study, entitled City of Carlsbad Water Reclamation Master Plan, was authorized by the City of Carlsbad and was jointly funded by the City of Carlsbad and the San Diego County Water Authority. The purpose of this study is to develop a master plan which would provide the City of Carlsbad a feasible water reclamation plan to serve the reclaimed water markets identified in this study. This study extends beyond previous works by presenting a phased water reclamation plan for the City of Carlsbad based upon evaluation of reclaimed water markets, reclaimed water sources, and distribution f facilities. b APPROACH P *• Initially, the exisitng environment of the study area was reviewed to provide a description of the study area, water reclamation planning in Carlsbad, water supply characteristics, *" wastewater characteristics, and reclaimed water policies, regulations, and requirements. ta The scope of the study required identification of potential reclaimed water users. The ^ study team identified well over 150 individual potential reclaimed water markets within the City of Carlsbad. After reclaimed water markets were identified, reclaimed water sources h* and distribution facilities were conceptualized and developed into alternatives and — subalternatives. Consideration was given to regulatory requirements, water quality to requirements, market size and location, and existing facilities. For this study, it was assumed that the facilities proposed in the Encina Basin Water Reclamation Project, -» Phase I Program Facilities Plan by John S. Murk Engineers, Inc. will be constructed, and to, therefore considered these facilities as Phase I of this Master Plan. Costs were developed for each alternative and used in an economic analysis to compare *" alternatives. The phasing of reclamation facilities with associated costs was developed !*• for the recommended plan. Common financing alternatives as well as special water reclamation financing methods that are available were researched. Separate financial *"" analyses were conducted utilizing low-interest state funding and revenue bond sales. ** Various implementation issues such as anticipated regulatory requirements, m intergovernmental agreements, and the need for a mandatory use ordinance were fc analyzed to develop specific recommendations for implementing the recommended plan. m ACKNOWLEDGEMENTS IP This report was prepared with the assistance of state and local agencies. In particular, m the cooperation and assistance of the following individuals and agencies are acknowledged: Pi (••xii Mr. Ralph Anderson, City of Carlsbad, Utilities & Maintenance Department m Mr. Peter MacLaggan, San Diego County Water Authority m Mr. LJoyd Hubbs, City of Carlsbad, Engineering Department Mr. Bob Greaney, Carlsbad Municipal Water District R Mr. William Rucker, Vallecitos Water District Ms. Joan Geiselhart, Leucadia County Water District E Mr. William Hunter, Encina Water Pollution Control Facility Mr. Doug Duncanson, City of Carlsbad, Parks & Recreation Department Mr. Mark Steyaert, City of Carlsbad, Parks & Recreation Department Mr. Tom Ham, California Department of Transportation Mr. Don Rideout, City of Carlsbad, Research and Analysis XIII p li p to CHAPTER 1 P SUMMARY AND RECOMMENDATIONS » m * 1.1 SUMMARY I 1.1.1 Description of the Study Area p The study area covers the entire area of the City of Carlsbad and covers approximately H 40 square miles. The City is divided into several different land use designations as identified in the General Land Use Plan. The total gross land use from the General Plan E is about 24,900 acres, of which 13,900 acres are designated as residential, 1,300 areas are designated as commercial, 2,200 areas designated as industrial, with the remaining land designated as schools, non-residential reserve, open space, railroad, streets, and p highways. » 1.1.2 Water Reclamation Planning in Carlsbadp» ^» Carlsbad's previous reclaimed water master plan reports are mostly outdated. The satellite treatment plants proposed in the late 1970's and early 1980's were to provide r secondary treatment at a time of sewer moratorium. In March 1978, a report entitled, ™ Overview of Waste Water Reclamation Opportunities, was prepared by Lowry & ^ Associates for the City which provided an overview of the need for reclamation. In September 1979, the City of Carlsbad Waste Water Reclamation Master Plan Study was *" prepared by Lowry & Associates, which recommended a master plan for staged P- . development of a reclaimed water system incorporating several satellite reclamation i. plants. *"• In May 1989, Luke-Dudek completed the Aviara Reclaimed Water Facilities Plan for the L City of Carlsbad. The report was prepared to serve as the first step toward obtaining a State low-interest loan for water reclamation facilities to serve the Aviara development. In *" May 1990, the CMWD applied for the State loan and prepared a mandatory use «• ordinance for reclaimed water. John S. Murk Engineers has prepared two studies: the San Diego Area Water Reuse Study, Volume V, Encina Basin Feasibility Study (Encina ^* Basin Feasibility Study) and the Encina Basin Water Reclamation Project - Phase I Facilities Plan (Encina Basin Facilities Plan). The Encina Basin Feasibility Study p, describes the water reclamation facilities required to produce reclaimed water in the " Encina Basin based upon a review of existing water demands and quality, an examination of regulatory requirements for reuse, and an evaluation of the potential p market for reclaimed water use. The Encina Basin Facilities Plan assess major potential II users of reclaimed water and develops several alternative projects. An analysis of each alternative is presented and a project is recommended which would be the first phase of m a basin-wide water reclamation project. 1-1 p It 1 .1 .3 Water Supply Characteristics P* !• Potable water delivered to the vicinity of the study area is supplied through a vast delivery system of the State Water Project and the Colorado River Aqueduct by the r Metropolitan Water District (MWD) and the San Diego County Water Authority (CWA). te The project site is under the jurisdiction of the Carlsbad Municipal Water District (CMWD), the Vallecitos Water District (VWD), and the Olivenhain Municipal Water District ** (OMWD), which purchase water from the San Diego CWA. Current potable water rates p, for domestic uses are $1 .01 per 100 cubic feet, or $440 per acre-feet. 1 .1 .4 Wastewater Facilities and Flow Characteristics ••» to The agencies providing wastewater collection and treatment services in the study area are the members of the Encina Joint Powers Agency (JPA) which are the Cities of *» Carlsbad and Vista, Vallecitos Water District, Encinitas Sanitary District (ESD), Buena •• Sanitation District (BSD), and Leucadia County Water District (LCWD). These six agencies own and operate the Encina Water Pollution Control Facility (WPCF). The ** facility was placed in operation in 1965 at a rated capacity of 4.5 mgd and is currently *• being expanded to a liquid capacity of 36 mgd. "* The VWD owns and operates the 2.0 mgd Meadowlark WRF which was constructed in ** 1982. The treatment plant is equipped with secondary and tertiary treatment facilities to meet California Administrative Code, Title 22 requirements for unrestricted use. The L Meadowlark Reclamation Facility (WRF) was designed for an ultimate expansion to 5.0 mgd. Since the draft master plan for the VWD has not been adapted, there are no p. current plans for expansion of the plant. tH The LCWD's Forest R. Gafner Wastewater Treatment Plant (WTP), which was *• constructed in 1962, provides secondary treatment for portions of the Cities of Encinitas bi and Carlsbad. The Gafner Treatment Plant is operating near its capacity of 0.75 mgd. The capacity of the plant was intended to be expanded to 1.5 mgd; however, the LCWD ** has no current plans to do so at this time. To provide reclaimed water for unlimited uses, ta the plant requires an upgrade to provide coagulation/flocculation, filtration, and extended chlorination. P ^™ The Lake Calavera Hills Water Reclamation Plant (WRP) was constructed to provide p, wastewater treatment for the Lake Calavera Hills Master Plan Community. The plant, ^ which was originally conceived as a 1 .2 mgd reclamation facility, was completed in 1981 and turned over to the City of Carlsbad, but was never operated until 1989. IP |g 1 .1 .5 Reclaimed Water Policies, Regulations, and Requirements p In California the specific requirements for the quality of reclaimed water and the effects m on the quality of receiving waters are established by the California Regional Water P m 1-2 H Quality Control Board (RWQCB). In addition to the RWQCB, the state and local Departments of Health Services retain special powers regarding the use of reclaimed E water. Statewide standards for the safe direct use of reclaimed water for irrigation and recreational impoundments have been established and are published in the California Administrative Code, Title 22.*• * Under the Porter-Cologne Water Quality Control Act of 1970, regulation of water pollution begins with adoption of a water quality control plan or "Basin Plan" by each B RWQCB. The study area is located in Carlsbad hydrographic unit as defined by the Comprehensive Water Quality Control Plan Report, San Diego Basin (9) (Basin Plan). _. Beneficial uses defined for groundwater in the basins located in the study area include 1 municipal and domestic supply, agricultural supply, and industrial service supply; however, the groundwater quality in most areas is high in total dissolved solids (TDS) §and does not meet the recommended criteria for either agricultural irrigation or livestock watering. p The State Department of Health Services (DHS) has established quality, treatment, L reliability and operational standards for the reuse of reclaimed water. These regulations are contained in Title 22, Division 4 of the California Administrative Code. The DHS r requires that an engineering report be prepared containing a detailed design of the i* proposed reclamation system. In addition to the detailed engineering report, a contingency plan is required to assure that no untreated or partially treated wastewater is r used. ^ The RWQCB issues State Waste Discharge Requirements to agencies producing [ reclaimed water, and discharging treated wastewater to land. The RWQCB issues federal National Pollutant Discharge Elimination System (NPDES) permits to agencies P discharging treated wastewater to navigable waters of the U.S. L The process for issuing water reclamation requirements is similar to that for issuing the r waste discharge requirements except that the process is initiated by sending the L RWQCB a letter stating who the user will be, and if available, an agreement between the user and the discharger. To the users and purveyors of reclaimed water, the RWQCB r issues a separate permit termed Water Reclamation Requirements, which describe the i« criteria and restrictions required for the safe use of the reclaimed water. u Reclamation of wastewater for irrigation must include a comparison of the quality of * reclaimed water with standards applicable to irrigation use. Salinity, measured in TDS, is m one of the most important water quality parameters in determining the suitability of L reclaimed water for irrigation. When reclaimed water is used for irrigation, salts may accumulate in the soil. E Toxicity due to a specific ions occurs when that ion is absorbed by the plant and accumulates in the plant in amounts that result in damage. Sodium, chloride, nitrogen f* and boron in high concentrations are of particular concern in irrigation because of their 1-3 lil potentially toxic effects on some plants. The forms of nitrogen found in wastewater, largely ammonium with some nitrate, behave in the same manner as applied fertilizer IP nitrogen. Excessive nitrogen levels may cause problems in some sensitive plants by H stimulating vegetative growth instead of flowering and fruiting. P 1.1.6 Reclaimed Water Markets It The extent of the reclaimed water market area for this project is the City of Carlsbad. The P existing potential markets lie in the developed areas of the City as well as agricultural * areas both north and south of Palomar Airport Road. Also, the rapidly expanding p industrial parks adjacent Palomar Airport Road provide additional potential markets. _ Future potential markets are found primarily in the eastern portion of the City. The City of Carlsbad General Plan allows further planned industrial and residential development p north of the Batiquitos Lagoon, southeast of Agua Hedionda Lagoon and east of El m Camino Real. •p In this study, the term "reclaimed water market" was used to identify a location where m reclaimed water could be used to replace the use or for future use of municipal (potable) water. Reclaimed water can also be used to replace the use of groundwater or improve ppl the quality of the groundwater that is being used, especially for irrigation purposes. *• Enhancement of riparian habitats is also a productive use of reclaimed water according to the RWQCB. Reclaimed water markets can be divided into three main categories: '"" irrigation uses, industrial/commercial uses, and ecological uses.ita ^ Irrigation uses of reclaimed water include the irrigation of pastures, crops, nurseries, golf courses, cemeteries, parks, campuses, and residential, commercial, and freeway ** landscaping. Irrigation water demands are non-uniform, varying seasonally from the *~ effects of wet and dry weather periods. The seasonal nature of crops also effects the ^ water demands of agricultural irrigation. Peak applications are applied during the dry summer months, and low applications occur during the wet winter months. The peak — reclaimed water demand in the study area at ultimate development for all types of *,» potential markets is about 21.4 million gallons per day (mgd). *" Golf courses provide a practical market for reclaimed water due to their large irrigation ^ demands. Water use by the California Department of Transportation (CALTRANS) for irrigation of landscape along freeways within San Diego County offers another potential """" market for reclaimed water. The City of Carlsbad maintains park turf and landscaping, ** school turf, and several landscaped areas. Residential and commercial/industrial m development landscape irrigation is a potential market for reclaimed water in the k developing areas of the City. Reclaimed water can be used to irrigate common areas in residential neighborhoods. Another beneficial use of reclaimed water would be to it irrigate fire breaks behind developments that border canyons, since brush-laden slopes jl present a major fire hazard. Agricultural operations in the City of Carlsbad are limited. About-1,100 acres supporting agricultural operations were identified as potential m reclaimed water markets.m P 1-4 * Industrial use of reclaimed water usually does not vary seasonally. Typical uses for industrial purposes within the market area include boiler water, cooling tower makeup p water, air conditioning uses, and process water. For this study, commercial use includes " the use of reclaimed water in a gray-water system. Reclaimed water could replace the 60 to 80 percent of a building total water consumption that is used in toilets and urinals. The streams and lagoons in the market area support lacustrine, riparian, and estuarine p. environments. Reclaimed water can provide additional freshwater flows for surface ^ waters during the dry season, thereby flushing and diluting poor quality dry season surface waters. Presently though, no definitive market currently exists. Groundwater i*» recharge is accomplished when reclaimed water is purified and stabilized as it percolates ^ vertically through the zone of aeration and moves laterally in an aquifer. The percolated reclaimed water enters and is stored in aquifers from which it can be withdrawn by wells *• and used for beneficial purposes. Aquifers in the study area are extremely limited and m are not candidates for reclaimed water discharge. Effective groundwater recharge requires an extensive aquifer with suitable geologic structure. Ecological uses of ** reclaimed water did not prove to be a potential reclaimed water market at this time for ^ the study area. I* 1.1.7. Alternate Project Description p, The planning period for this study extends from today through 2015. The components of L the water reclamation system include treatment facilities, pumping facilities, distribution pipelines, and storage facilities. to Alternatives were developed to produce sufficient reclaimed water to meet the peak seasonal demands of the majority of the potential reclaimed water markers in the study «• area. The alternative projects were developed based on the following assumptions: to • Title 22 treatment facilities will not be used on a continuous basis throughout the * year, but will process reclaimed water to meet the peak seasonal demands. • Proposed storage facilities and distribution would be sized to deliver the peak J seasonal reclaimed water demand in a eight hour irrigation period. _ • Reclaimed water treatment and distribution facilities identified in the Encina Basin H Facilities Plan and the Aviara Reclaimed Water Facilities Plan by Luke-Dudek would be constructed as Phase I of the ultimate reclaimed water facilities. P |j • Alignments were chosen to form logical distribution systems to minimize pipe runs and sizes. For the most part pipelines run in either existing or proposed streets » where practicable. Hydraulic analysis of the distribution system was done using the ft University of Kentucky KYPIPE network analysis software. m ik. 1-5 m to • Reservoir locations were set so that the hydraulic grade line established would R provide adequate pressures for the majority of the markets in that service zone ™ without the need of auxiliary pumping. p*L • Reclaimed water distribution systems presented are based on a certain degree of refinement to arrive at a realistic and workable distribution network, they were not B optimized, and there are probably variations in the alignment of pipelines, and the location and height of reservoirs that would result in a more cost effective reclaimed water distribution system. If The alternatives were based on location of proposed Title 22 facilities, location of markets based on Basin Plan TDS restrictions, location and number of proposed B reclaimed water reservoirs. The possible storage scenarios were storage at (1) the existing Mahr Reservoir only, (2) the existing Mahr Reservoir and a new reservoir in northeast Carlsbad, (3) the existing Mahr Reservoir, and an existing reservoir in the P southwest portion of Carlsbad with an intermediate pump station, and (4) the existing " Mahr Reservoir, a new reservoir in the northeast section of Carlsbad, and an existing reservoir in the southwest portion of Carlsbad area with an intermediate pump station. g^ Four alternatives were developed by combining the criteria listed above for the location ,,» of proposed Title 22 facilities and the location of markets. Alternative 1 proposed the ^ location of Title 22 facilities in the vicinity of the Encina WPCF and serving all markets. Alternative 2 proposed the location of the Title 22 facilities located in the vicinity of the P- Encina WPCF and serving all markets except irrigation markets within the area with y groundwater TDS limitations of 1,200 mg/l. Alternative 3 proposed the location of the Title 22 facilities in the vicinity of the Encina WPCF and at the Lake Calavera Hills P treatment plant and serving all markets. Alternative 4 proposed the location of the Title i» 22 facilities at both the Encina WPCF and at the Lake Calavera Hills treatment plant, serving all markets served except irrigation markets within the area with groundwater "" TDS limitations of 1,200 mg/l.i» ^ In addition to the four water reclamation project alternatives, there is a "No Project" i alternative which would consider that all future needs that could be met with reclaimed water would be provided by potable water. The net effect of this alternative would be that p» in the future local and regional potable water storage, transmission and distribution |i facilities would need to be added to provide for the future water demands. m 1.1.8 Alternative Project Analysis •To avoid numerous alternatives, the subalternatives were analyzed under the conditions • of Alternative 1 (proposed Title 22 facilities in the vicinity of the Encina WPCF and serving • all markets) by comparing capital costs and non-monetary considerations. From the subalternative analysis, it was determined that using only the existing Mahr Reservoir (in B addition to a reservoir required to serve the higher elevation) would provide the most suitable storage and distribution system. The four alternatives were further developed using this storage scenario. The capital costs of the distribution and treatment facilities and total annual operations and maintenance (O&M) costs for each alternative, not including Phase 1, are as follows: m Distribution Facilities Treatment Facilities Annual O&Mf m P m Alternative 1 Alternative 2 Alternative 3 Alternative 4 $40,827,000 $31,140,000 $41,445,000 $31,756,000 $8,570,000 $7,757,000 $9,267,000 $8,062,000 $1,930,000 $1,592,000 $1,964,000 $1.632,000 Based on data from the County Water Authority, the incremental cost of providing potable water is estimated to be about $690 per acre-feet for the water development costs, not including the retail agency capital costs, and operational and maintenance costs. The cost of the "No Alternative" project then would be $7,590,000, based on the construction of future potable water facilities to provide for 11,000 acre-feet of demand per year. An economic analysis was performed to compare each of the four alternatives. The capital costs and salvage values were annualized over a 20-year planning period using a discount rate of 7.5 percent. A unit cost for each alternative was calculated for each alternative. Based on the treatment and distribution facilities cost per unit of reclaimed water produced, Alternative 1 was determined to be the most cost effective. The capital costs include construction costs; costs for engineering, legal and administration, and construction management costs; land costs; and contingencies. The contingency accounts for unforeseen difficulties, modifications made during final design, and uncertainties that are unavoidable during preliminary design. Land costs are included in the estimate for off-site tertiary treatment facilities. Land costs were not included for pipelines since it was assumed they will be constructed within public right-of- ways. Engineering and construction management costs for construction projects include special site investigations; aerial surveys; geotechnical analysis; preparation of contract drawings and specifications; construction inspection; other engineering services during construction; construction administration; material testing; final inspection; and start up of the completed facilities. Included as O&M costs are labor, power, supplies, administration and other incidental costs. 1-7 f» m 1.1.9. Recommended Project The recommended project is Alternative 1. The physical components of the recommended plan include tertiary facilities in the area of the Encina WPCF, a new storage tank, the existing Mahr Reservoir, a reclaimed water distribution pump station at the site of the tertiary facilities and at the Mahr Reservoir, and the distribution pipeline system. Phase I of the plan would consist of the facilities described in the Encina Basin Facilities Plan. The sources of supply for Phase I would be the Meadowlark WRF and Gafner WTP, and the proposed users would be the Aviara development, La Costa Hotel, CALTRANS, Frazee Flowers, and Ukegawa Farms. Facilities constructed during Phase II include 30- and 36- inch pipelines from the distribution pump station to the Mahr Reservoir, the tertiary facilities, and the reclaimed water distribution pump station. The facilities would serve markets in the southwest area of the City and the area north of Palomar Airport Road and El Camino Real. During Phase III the tertiary facilities and distribution pump station would be expanded to serve a large number of markets in the northern part of the City. In Phase IV, the tertiary facilities and the distribution pump station would be expanded and four branches of the distribution pipeline would be added, serving markets in the southwest, southeast and northern parts of the City. In Phase V, the distribution pipeline system would be expanded to serve the higher elevations in the City by constructing a new reservoir and pump station, and the tertiary facilities and distribution pump station would be expanded to the ultimate capacity. The capital costs, schedule date of operation, and total amount of reclaimed water produced are as follows: p h i m to Phase I Phase II Phase III Phase IV Phase V Capita! Costs $6,366,000 16,249,000 13,678,000 9,623,000 9,142,000 Date of Operation 1992 1997 2002 2007 2012 Total Reclaimed Water Use 2,354 AF/YR 4,240 AF/YR 6,850 AF/YR 8,590 AF/YR 11,480 AF/YR 1.1.10 Project Funding Whatever institutional arrangements are ultimately established for the construction and operation of the water reclamation facilities and associated reclaimed water distribution system in the City of Carlsbad, it is assumed for this study that the agencies involved will not have the cash reserves available for the construction. It is unlikely also that sufficient cash flow is currently being generated to operate and maintain the proposed facilities. 1-8 Thus, several methods for generating necessary capital for construction and revenue for O&M will be required. In addition to traditional financing methods such as Mello-Roos Community Facilities Act of 1982, special assessment districts, lease purchase, joint powers authority, public facilities corporation, revenue bonds, lease revenue bonds, certificates of participation, and special obligation bonds, there are local and regional financing methods unique to water reclamation projects. These include programs sponsored by the CWA, MWD, and the State of California. From the review of reclaimed water pricing by various local agencies in Southern California which are implementing successful water reclamation programs and on a literature review of the subject, it becomes clear that there is no standard methodology being conducted for reclaimed water pricing. For the purposes of this report, financial analyses were complied based on different scenarios of the price of reclaimed water as a percentage of the cost of potable water. With the State low interest rate loan and the cost of reclaimed water set at 91% of the cost of potable water, annual expenditures would balance annual revenues. With revenue bonds instead of State low interest rate loan, expenditures would balance revenues when the price of reclaimed water is 109% of the cost of potable water. The purpose of a financial analysis is to determine if the projected revenues from the sale of reclaimed water and other sources are sufficient to meet the debt service for construction of the facilities and the annual O&M costs. Two financial analyses were performed; one based on revenue bond financing for capital costs, and the other based on State low-interest financing for capital costs. Several potential methods for funding the deficit years of the project are possible such as increasing sewer service charges, sewer connection fees, or potable water service changes. The financial analyses are presented as pro forma statements. The costs used in the financial analyses include: capital costs, annual O&M costs, reimbursement payments for existing facilities at the Meadowlark and Gafner treatment plants, and debt service payments. In addition to the revenue received through either a State low-interest loan or revenue bonds, the analyses includes revenue from MWD rebate monies and from the sale of reclaimed water. A rate of 4.25 percent was used for the State low-interest loan analysis and a rate of 8.5 percent was used for the revenue bond analysis. The financial analyses demonstrate that the recommended plan is financially feasible when a calculated price for reclaimed water is used or additional revenues to offset deficits are received from increased water service charges. State low-interest loan funding would require that the price of reclaimed water be set at 91% of the cost of potable water for no deficit. With revenue bond financing, the price of reclaimed water would need to be set at 109% of the cost of potable water for no deficit. An in-depth analysis to determine which financing mechanism is best suited for financing the project 1-9 Mi has not been done, but it appears that increased service charges or connection fees would accommodate the revenue stream in the case of either a State low-interest loan or "* the sale of revenue bonds. Also, in both analyses, a reserve is built up that could be ** used to construct replacement facilities. 1.1.11 Plan Implementation p It is likely that an environmental impact report (EIR) will be required for the construction j^ of the treatment and distribution facilities described in this plan. The preparation, review, and certification of this document can be expected to take at least nine months. The m construction of the reclaimed water treatment, storage, pumping, and distribution H facilities located within the coastal zone will require a coastal development permit from the California Coastal Commission. m • The CMWD must prepare and submit to the RWQCB a Report of Waste Discharge as an update to the Water Reclamation Requirements which fully describe the proposed water E reclamation plan. The existing Waste Discharge Requirements for the Meadowlark WRF and the Gafner WTP are expected to be adequate for the reclamation plan. The Encina WPCF will require a new Report of Waste Discharge as application for modified Waste f* Discharge Requirements for the new reclaimed water treatment and distribution system. to ,„, Agreements will be required from the suppliers of the reclaimed water, the Encina JPA, the VWD, and the LCWD, and the water purveyors, the VWD and the OMWD. User *" participation and commitment is an important aspect in the implementation of the plan. It r. has been proposed that the OMWD obtain letter of commitments from the proposed ^ Phase I users. The letter of commitment would define the understanding between the user and the City and would discuss responsibility for the reclaimed water distribution •- system, quantity of reclaimed water to be provided, delivery schedule and pricing, and ta point of connection to service. "" The OMWD has applied for a low interest loan from the State Water Resources Control >*• Board (SWRCB) for the Phase I facilities. The OMWD will need to establish a pricing policy prior to distribution of reclaimed water. It is recommended that the price of *" reclaimed water be at or higher than the retail price charged for potable water. Revenues ** from the sale of reclaimed water at that price, will be sufficient to support a positive m revenue flow and build a reserve. A more detailed study will be necessary to develop the : organizational structure for financing and to refine the revenue stream necessary to support the debt service. M li A mandatory reclaimed water use ordinance or resolution be adopted by the OMWD: In accordance with State law that prohibits the use of potable water for irrigation when JP reclaimed water is available, the use ordinance will insure that as much reclaimed water • as reasonably possible will be used by the OMWD. p M pL 1-10 IP k *• The RWQCB requires the preparation of reclaimed water handling Rules and Regulations for a purveyor of reclaimed water and for the user of reclaimed water. The City of *"* Carlsbad already has Rules and Regulations for the City; and the user of reclaimed water ** an adopt and use the City's Rules and Regulations. The City will be responsible for the ^ enforcement of these regulations. The Rules and Regulations for the City of Carlsbad are included as Appendix I. p The CMWD will be responsible for O&M of the reclaimed water system. General O&M of y the facilities will be integrated with the CMWD's present operation and maintenance activities.

The development and evaluation of alternative water P reclamation plans is dependent on the physical characteristics of this study area. This Chapter describes the study area location, and discusses the physical geography and p, topography, climate, and hydrologic features. 2.2 STUDY AREA m HI The study area covers the entire area of the City of Carlsbad, and is shown in Figure 2-2. The incorporated area of the City includes portions of several water and sewer f* agencies, which are described in Chapter 4 and 5. The City covers approximately 40 li square miles, and is bounded by the City of Oceanside to the north, the Cities of Vista and San Marcos to the east, the City of Encinitas to the south, and the Pacific Ocean to ^ the west. M m 2.3 TOPOGRAPHY m The City of Carlsbad is located within the San Diego Coastal Plain region. The coastal P. plain appears as flat-topped mesas or terraces and steep-walled canyons. These mesas ^ begin just behind the beaches and are considerably modified by erosion. p- Elevations range from sea level along the ocean to 980 feet near the coastal foothills in fc, the southeastern area of the City. The natural slopes vary from almost flat along the coastal, terrace and mesa tops to near vertical cliffs along the canyons.P* m 2.4 CLIMATE P The study area extends from the Pacific Ocean, which is the major influence on coastal " Southern California weather, to the coastal hills approximately 6 miles inland. Early morning and late evening fog in fall and late spring; dry, warm summers; and cool, I moderate winters are typical of the subtropical climate experienced in northern San Diego County. p m The temperature range increases with distance inland from the coast, with an average annual temperature in the low 60's on the coastal plain and in the coastal valleys. The p mean temperatures for the study area range from 55 ° F in January to 67 ° F in August. 2-1 COUNTY COUNTY ' POj LEGEND STUDY AREA/CITY OF CARLSBAD 0 16,000 32,000 FT.

FIGURE 2-2 STUDY AREA DUDEK & ASSOCIATES, INC 2-3 ^ Winds near the coast, which result from large scale circulation from the ocean, are generally light to moderate, though infrequent gusty Santa Ana wind conditions do occur *• in the fall and summer. Winds are predominantly from the west and northwest, with wind iw velocities rarely exceeding 30 miles per hour. ** The average seasonal precipitation along the coast is approximately 10 inches, and * increases with elevation as storm fronts move to the east. Most of the precipitation occurs between November and March. Thunderstorms occur less than three days per "" year along the coast.ft 2.5 HYDROLOGY u The City of Carlsbad is crossed by three major east to west trending creeks: 1) Buena p Vista Creek near the boundary with Oceanside, which terminates in Buena Vista Lagoon; |j 2) Agua Hedionda Creek, which terminates in Agua Hedionda Lagoon; and 3) San Marcos Creek, which terminates in Batiquitos Lagoon. In addition, Canyon de las p Encinas originates within the City limits, flows west along Palomar Airport Road, and H enters the ocean directly without a lagoon. P Precipitation over the City occurs mainly during November through March, although H local thunderstorms of short duration and high intensity do occur at other times of the year. Mean annual precipitation varies from 10 inches along the coast to 16 inches in the ** coastal range to the east. Most of the creeks are dry during the summer, with only the ^ major streams having small dry-weather flows. 2.6 LAND USEto P. The City of Carlsbad is divided into several different land use designations as identified ^ in the City's General Land Use Plan adopted in 1974 and updated in 1983. Figure 2-3 shows the land use areas as well as school and public utility locations. All residential F- uses such as high, medium, and low density residential uses are designated as !• residential. Similarly, the several types of commercial uses are categorized collectively as commercial. The term mixed use on Figure 2-3 indicates an area where more than f* one land use was designated on the General Plan. Table 2-1 shows the acreage for <H various land uses in the General Plan as provided in the Citywide Facilities and Improvement Plan (Citywide Plan) dated September 16, 1986. The Citywide Plan is the f first phase in the implementation process of the City's Growth Management Ordinance ** which was adopted by Ordinance No. 9810 on July 1, 1986 by Carlsbad City Council. The Citywide Plan will implement the City's Growth Management Program and zoning jjL ordinances by ensuring that development does not occur unless adequate public facilities and services exist or can be provided concurrent with new development. |»jg The objectives of the Land Use Element of the General Plan are to provide predominantly single family residential housing with higher density residential ft development located near commercial coves. The Palomar Airport Road corridor will be (I primarily industrial and mixed use, with an agricultural preserve at the west end. 2-4 '"LM/ Ji^jcv. - £ -. >T-*-»**,^-^ ->«LEGEND STUDY AREA/CITY OF CARLSBAD BOUNDARY OPEN SPACE j PLANNED INDUSTRIAL RESIDENTIAL NON-RESIDENTIAL RESERVE GOVERNMENT COMMERCIAL MIXED USE SCHOOL PUBLIC UTILITY 0 2500 5000 FT. FIGURE 2-3 CITY OF CARLSBAD GENERAL LAND USE PLAN DUDEK & ASSOCIATES, INC. 2-5 pi to mi Portions of the City are located within the Coastal Zone, and therefore are controlled by the Mello I and II Local Coastal Programs (LCPs) which were adopted by The Coastal Commission in 1981 and 1982. The Coastal Zone boundary is shown on Figure 2-2. In October 1985, the City of Carlsbad proposed revisions to the Mello LCPs which were approved by the Coastal Commission and incorporated into official City policy. These revised Mello I and II LCPs are the primary land use documents for portions of the City. Although not as site-specific as the Mello LCPs, the City of Carlsbad General Plan policies are also in effect. Zoning provisions were also approved to facilitate implementation of the General Plan and Mello LCPs. Both the Mello I and Mello II LCP Land Use Elements contain policies regarding agriculture and the grading of steep slopes, and require that development occur under a Master Plan. Land located within the Mello I district is designated as agricultural land or various residential densities, depending on the capacity class of the soil as determined 'by the Soil Conservation Service and the steepness of the slopes. The Mello LCP policies regarding drainage and erosion control are also very specific. The Mello I and Mello II LCPs provide for urban conversion of non-prime agricultural lands under specific conditions or subject to specific mitigation. In addition to the land use requirements of the local coastal programs, the Coastal Commission has specific guidelines and policy documents regarding developments of wetlands and required buffer zones. The primary applicable policies in the San Dieguito LCP include policies designed to protect environmentally sensitive habitats, such as coastal mixed chaparral and coastal sage scrub; policies to prevent further degradation of wetlands, to reduce sedimentation and to restore the lagoon's water quality and productivity; and policies to allow the conversion of non-prime agricultural lands. Visual resource policies are also contained in the San Dieguito LCP. Most of the requirements of the San Dieguito LCP have been incorporated into the newly-revised Mello LCPs. The Mello LCPs are implemented through the zoning ordinances of the local coastal programs, revised in October 1985, and through revisions to the City of Carlsbad's P-C (Planned Community) zoning ordinances.

The satellite treatment plants that were proposed in the late 1970's and early 1980's to provide secondary treatment at a time of sewer moratorium, with the exception of the Lake Calavera Hills plant were not constructed. The 1.2 million gallon per day (mgd) Lake Calavera Hills plant has never been operated, and cannot meet the strict reclaimed water treatment levels for unrestricted irrigation usage. Numerous water reclamation studies and reports have been prepared for the Carlsbad area which are listed in Table 3-1, found at the end of this Chapter, and described in the following paragraphs. 3.1.1. 1978 Overview Report In March 1978, a report entitled, Overview of Waste Water Reclamation Opportunities, was prepared by Lowry & Associates for the City. The report provided a comprehensive overview of the need for reclamation and a discussion of related information and issues at the time, including: • Reclamation program development, • Reclamation potential, • Satellite plant locations, • Reuse locations, • Storage and fail-safe requirements, • Cost analysis, and • Regulatory compliance. The report concluded that there was a viable, opportunity to establish a wastewater reclamation and reuse program, and that the needs for agricultural irrigation water in 1985 would be greater than the reclaimed water production. This conclusion was based on land use figures provided by the Comprehensive Planning Organization which showed about 9,000 acres of land classified as agricultural by 1985. The second largest potential reclaimed water use identified was landscape irrigation, followed by open- space irrigation, recreational impoundments and industrial reuse. The study recognized the need for a fail-safe connection to the Encina ocean outfall during times when the reclaimed water could not be used. The report presented a conceptual plan showing tentative location of satellite reclamation plants and reuse sites. The plants would mostly serve the City of Carlsbad but also the surrounding community and would be operated by Carlsbad, the Leucadia 3-1 County Water District (LCWD), Vallecitos Water District (VWD), Vista Sanitation District and the Encina Joint Advisory Committee. Proposed satellite plant locations included the Encina Water Pollution Control Facility (WPCF), Palomar Airport, along Buena Vista, Agua Hedionda and Batiquitos Lagoons, in La Costa, and near the existing Lake Calavera Hills, Gainer, Meadowlark, and Shadowridge treatment plants. The preliminary financial analysis in the report indicated there would be no massive commitment of public funds, and that the cost of the program would be borne by a combination of contributions by local developers, payments by reclaimed water users, and possible grant funding. 3.1.2 1979 Master Plan Study In September 1979, the City of Carlsbad Waste Water Reclamation Master Plan Study was prepared by Lowry & Associates. The study area encompassed the entire City and its sphere of influence with the exception of those lands served by the LCWD and the VWD, and the Lake Calavera Hills Water Reclamation Plant (WRP) study area. The study recommended a master plan for staged development of a reclaimed water system incorporating several satellite reclamation plants. Initially the plants were conceived to produce reclaimed water for the irrigation of agricultural land. It was visualized, however, that with future urbanization, irrigation of landscaping and open space in residential areas would gradually supplement agricultural irrigation as a potential market. Industrial use of reclaimed water was encouraged but not quantified. The master plan was conceived as one of several methods for alleviating the City sewer moratorium that existed at that time. Satellite reclamation plants were considered as a means for providing additional treatment capacity while furnishing a significant source of supplemental non-potable water. The City Council desired to develop the master plan for wastewater reclamation within its jurisdiction before giving further consideration to additional satellite treatment plants, such as the one that had been approved for the Lake Calavera Hills development. The master plan presented the following: • Population and land use data, • Description of reclamation concepts, • Location and capacity of potential wastewater reclamation plants, • Opportunities for use of reclaimed water and associated volumes, and • Costs and scheduling. The master plan recommended the construction of four satellite reclamation plants described as follows: • Batiquitos Reclamation Facility - would provide reclaimed water to agricultural areas lying north and west of Batiquitos Lagoon. The 0.4 mgd secondary treatment plant 3-2 would be constructed near the existing Batiquitos Lagoon sewerage pump station. The initial potential market would be 614 acres of agricultural land, west of Interstate 5 where no demineralization would be required. • Palomar Airport Reclamation Facility - would be constructed at the confluence of major sewer lines immediately south of Palomar Airport, and would serve reclaimed water to the abundant agricultural areas nearby. The estimated reuse market would be about 2,450 acre-feet per year (AF/YR) in that area, and an initial 2.6 mgd secondary plant was proposed. Wastewater from Carlsbad, San Marcos, and Buena would be treated there. In a later stage the plant would be expanded to 5.0 mgd, with a pipeline to serve coastal markets. • Encina Reclamation Facility - would be constructed at the Encina WPCF site. The reclamation portion of the plant would be relatively small and developed in later stages of the master plan. The 1.0 mgd reclamation facilities would require demineralization because of high total dissolved solid contents of wastewater collected at the Encina WPCF, and the reclaimed water would serve nearby agricultural, landscaping, and industrial users. • Buena Vista Reclamation Facility - would provide up to 0.5 mgd of secondary effluent by rehabilitating the abandoned City of Oceanside's treatment plant located on the Buena Vista Lagoon near the El Camino Real crossing. Most flows would come from the Vista Sanitation District and the City of Oceanside. Unlike the other three reclamation plants proposed, the Buena Vista plant would have no direct ocean outfall access as a fail-safe. Thus, the plant would be operated on an as-needed basis. That is, treating only the amount of wastewater needed for the immediate reclamation market, up to 85 acres of landscaping. Again, the immediate focus of the master plan was upon those portions of the City outside of Lake Calavera Hills and the Leucadia and Vallecitos Water Districts. The Lake Calavera Hills WRP study had been prepared for the City in 1978, by the consulting firm of James M. Montgomery, Consulting Engineers, Inc. in a reported titled, Environmental Impact and Facilities Plan for a Satellite Sewage Treatment Facility. The Leucadia and San Marcos County (Vallecitos) Water Districts were planning their own reclamation master plans at that time. Although not independently studied in the Master Plan, the results of the James M. Montgomery study of the Lake Calavera Hills WRP were incorporated. The Montgomery report proposed a 1.2 mgd satellite reclamation plant approximately one mile southwest of Lake Calavera to serve the 3,700 acre Lake Calavera Hills development. As planned, the effluent from the Lake Calavera reclamation facility would have been initially percolated into the groundwater basin immediately upstream of the Agua Hedionda Lagoon and pumped back out for agricultural irrigation. It was later proposed to construct an excess effluent line to the Encina ocean outfall. 3-3 ** With the previous expansion of the Encina WPCF, which was completed in 1983, and included an upgrade to secondary treatment, the sewer moratorium in Carlsbad was "~ ended. With additional capacity at the Encina WPCF, the return of extremely wet years in ** California, and the existence of a waiver from secondary treatment at the Encina WPCF, reclamation became less of an issue. None of the four reclamation plants proposed in m the 1979 Master Plan Study, the Batiquitos, Palomar Airport, Encina, and Buena Vista t" plants, were constructed. t* H 3.1.3 Basin Plan Revision pi In November 1980, two reports were completed for submittal as amendment requests to ^ the San Diego Regional Water Quality Control Board's (RWQCB) Comprehensive Water Quality Control Plan. The studies completed by Luke-Dudek Civil Engineers were titled IP" Proposed Revision Basin Plan Objectives - Carlsbad Hydrographic Subarea, and to Proposed Revision Basin Plan Objectives - A Portion Of The Agua Hedionda Subarea. The studies successfully provided sufficient analysis of these two groundwater basins to ** allow the San Diego RWQCB to significantly relax its groundwater objectives in and % around the Lake Calavera Hills area, thus, eliminating the need for costly demineralization of the Lake Calavera Hills WRP's reclaimed water.p> * 3.1.4 Lake Calavera Hills In May 1983, a report entitled Lake Calavera Hills Reclamation System Update Report ** was prepared by Glenn M. Reiter & Associates. The purpose of the report was to p. answer four questions: • Is there a demand for non-potable water, and if so, what is the demand, where is *- it, and how permanent is it? IM • What capital facilities will be required to complete the Lake Calavera Hills WRP •" reclamation program? to • When is the most opportune time to initiate a wastewater reclamation service? ** • What are the costs for a reclaimed water program? The report concluded that there is a market for non-potable water in an area that lends * itself to the efficient distribution of reclaimed water from the Lake Calavera Hills WRP, p, and that: %• The market is in a basin that does not require demineralization, IP * • The proposed distribution system is flexible and adaptable to meet demands, 3-4 • There is sufficient time to prepare for the implementation of the program, thus, ensuring the economic viability of the project at the most opportune time, and • Reclamation should become a viable, economical program in the middle or late 1980's. 3.1.5 Costa Real Municipal Water District Non-Potable Master Plan In September 1982, the Costa Real Municipal Water District (CRMWD) completed a report titled, Overview for Public Non-Potable Water Sources and Master Plan for Public Non-Potable Water System, prepared by Woodside/Kubota and Associates, Inc. The report restated much of the work done in previous reclamation studies referenced, such as available reclaimed water sources and potential use areas, with a particular emphasis toward the goals and objectives of the CRMWD. The conclusions are summarized briefly as follows: • A number of treatment plants are in the area with effluent pipelines passing through the CRMWD service area, • Agricultural and dry-land areas in the CRMWD are urbanizing with needs for landscaping irrigation, • The CRMWD, with its advantage of experience as an existing water purveyor, viewed the non-potable market place as growing and non-potable service as becoming cost effective, • The CRMWD provided a map of proposed non-potable water lines within its service area which showed interrelation with existing potable water lines and potential use areas, and • Success of the program will be based on the ability to design an appropriate financing program. 3.2 CURRENT WATER RECLAMATION PLANNING 3.2.1 Lake Calavera Hills Water Reclamation Plant The Lake Calavera Hills WRP, which is owned by the City of Carlsbad, was partially constructed in 1981, though a failsafe pipeline was never constructed. The existing facilities would provide secondary treatment only, using the activated sludge process in the form of an oxidation ditch. While the design capacity of the plant is 1.2 mgd, the estimated current flow rate possible to the plant from its service area is 0.25 mgd, and in five years will be about 0.56 mgd according to recent studies. Some of the major improvements needed to make the plant operational are: 3-5 • Completion of a fail-safe pipeline to the Encina ocean outfall for excess effluent or untreated wastewater, • Completion of a sewage pump station at Tamarack Avenue and El Camino Real, and • If on-site solids handling is not desired, construction of a gravity pipeline to the Encina WPCF is required for solids removed at the Lake Calavera Hills WRP. 3.2.2 La Costa Country Club Reclamation The La Costa Country Club (La Costa) currently uses reclaimed water to irrigate up to 15 holes of its 36 holes of golf course during six months of the year. The reclaimed water is produced at the Meadowlark WRF which is owned and operated by the VWD. The reclaimed water is wholesaled to the City of Carlsbad which then sells the water to La Costa according to procedures established in several documents, including these issued by the San Diego RWQCB: • Order No. 84-10, "Water Reclamation Requirements for the City of Carlsbad for the Purveyance Water in San Diego County," adopted by the San Diego RWQCB on January 23, 1984, and which allows the City to distribute within its boundary reclaimed water produced by the Vallecitos Water District's Meadowlark Water Reclamation Facility • Order No. 84-11, "Water Reclamation Requirements for the La Costa Hotel and Spa, San Diego County," adopted by the San Diego RWQCB on January 23, 1984, and which provides for the La Costa Hotel and Spa to use reclaimed water for landscaped irrigation, • Order No. 87-81, "Waste Discharge Requirements for San Marcos County Water District Meadowlark Reclamation Project", adopted by the San Diego RWQCB on May 4, 1987, and which establishes the Vallecitos Water District as a wholesaler of reclaimed water to the City of Carlsbad, and • Order No. 87-82, "Waste Discharge Requirements for Leucadia County Water District Forest R. Gafner Water Reclamation Plant near the City of Carlsbad, San Diego California" adopted by the San Diego RWQCB in May 1987, and which states up to 0.75 mgd of effluent from the Gafner plant will be used for irrigation of the La Costa Golf Course. Reclaimed water is used only during the drier six months of the year at La Costa because the ponds which store and help distribute it are not protected from 100-year flooding. Thus, the RWQCB has determined that these ponds must either be protected from flooding in the wetter half of the year, or a federal permit must be applied for allowing discharges to San Marcos Creek. 3-6 The reclaimed water provided to La Costa meets the strictest treatment requirements of the State Health Department, and therefore can be used for all types of irrigation or landscape impoundment replenishment with unrestricted public access. La Costa takes the reclaimed water on an as-needed basis with no formal agreement with the City. La Costa's managers have not agreed to take reclaimed water in a long-term contract. This situation has become a problem for the nearby Leucadia County Water District which also desires to produce reclaimed water for La Costa, and has constructed a pipeline from the Gafner Water Treatment Plant (WTP) to La Costa's lower irrigation water storage lakes. LCWD would like to upgrade its secondary plant to meet the most restrictive State Health Department requirements for reclaimed water, and has already received conceptual approval from the State Water Resources Control Board (SWRCB) for a low-interest loan to do so. The one stumbling block is the SWRCB need for a user agreement for at least fifty percent of the reclaimed water produced by the upgraded plant. Before approving any loan money for reclaimed water facilities, the SWRCB has asked for an executed user agreement or the existence of a mandatory reclaimed water use ordinance within the boundaries of the overseeing agency. 3.2.3 Agreement With Carlsbad Municipal Water District On May 25,1983, an agreement between the City of Carlsbad and CRMWD titled "Water Service Agreement" was executed. The Agreement provides an understanding of how water service duties will be provided by the City and the District. This agreement has been superseded by the 1989 Costa Real - City of Carlsbad Agreement which established the Costa Real Municipal Water District as a subsidiary district of the City (see Appendix A). The 1989 Agreement takes effect on January 1, 1990, and changes the District's name back to Carlsbad Municipal Water District. The responsibilities of the City and the District are divided as follows: City of Carlsbad City Council Responsibilities Adopting Ordinances Adopting Annual Budgets Adopting Annual Capital Improvement Plans Adopting Annual Financial Statements Approving Any Debt Issuances Setting Annual Tax Rates, Water Rates and Developer Charges Making Commission Appointments Authorizing Non Budget Expenditures Authorizing Expenditures Exceeding Budgeted Amounts Approving of Any Acquisition or Lease of District Property Approving Employment Contracts and Setting Salary and Benefit Packages 3-7 Carlsbad Municipal Water District Water Commission Responsibilities • Developing Potable Water Master Plans • Developing Annual Capital Improvement Plans • Developing Annual Financing Plans • Developing Annual Budgets and Expenditure Plans • Developing Water Conservation Programs • Developing Water Reclamation Programs (Master Plan Input Also) • Recommending Actions on Agenda Items for Board of Directors Consideration In July the City adopted a set of standard plans, specifications, and regulations for the installation, construction, and operation of reclaimed water facilities titled, "Rules and Regulations for Reclaimed Water Service Provided By the City of Carlsbad In Its Service Area". In May 1990, the CMWD adopted a water reclamation ordinance mandating the use of reclaimed water to maximize resource conservation and to streamline implementing reclamation projects by setting regulations for reclaimed water use. The CMWD will continue to be involved in initiating the implementation of the water reclamation recommendations in the master plan, which will be adopted by the City of Carlsbad as the Board of Directors for the CMWD. 3.2.4 Encina Basin Feasibility Study In 1987 and 1988 the six-volume San Diego Area Water Reuse Study was completed. The studies discuss water reclamation county-wide in an Overview Report, and specifically in the Encina Basin, San Dieguito Valley, San Pasqual Valley, Santee/San Diego River Basin, and in the Otay Basin. The studies were funded through a Section 201 Water Reclamation Study Grant of the Federal Clean Water Grant Program by the U.S. Environmental Protection Agency (EPA) and the SWRCB. The City and County of San Diego were joint recipients of the grant and both contributed local funds to the projects completed. In May 1987, the San Diego County Board of Supervisors directed its Chief Administrative Officer (CAO) to use a portion of the San Diego Water Reuse Study funds to further study water reclamation potential in the Encina Basin, particularly the "live- stream" discharge of reclaimed water to convey it from satellite reclamation plants to downstream users. The CAO's Special Projects Office was placed in-charge of the administration of the water reclamation study for the Encina Basin. In February 1988, a report titled San Diego Area Water Reuse Study, Volume V, Encina Basin Feasibility Study (Encina Basin Feasibility Study) was completed by John S. Murk Engineers. The Encina Basin Feasibility Study, reviews the existing water demands and existing water quality in the Encina Basin, examines the regulatory requirements for water reuse in the Basin, evaluates the potential markets for reclaimed water use in the 3-8 c area, and describes the water reclamation facilities required to produce reclaimed water in the Encina Basin.r ** The study describes the Encina Basin as 77,000 acres in size, with a population in 1980 of 137,400. It includes portions of the Cities of Vista, San Marcos, Carlsbad, and J* Encinitas. Existing potable water supply to the Encina Basin consists of 70 percent ** imported water and 30 percent local surface water from Lakes Henshaw and Hodges. Groundwater resources in the Basin are utilized only by a few privately owned wells for ' residential use, irrigation, and sand washing; however, groundwater quality is poor. The total dissolved solids (TDS) content ranges from 980 to 3,630 milligrams per liter (mg/l) p. and the chloride levels average 465 mg/l. Wastewater from the Encina Basin is primarily treated at the Encina WPCF. There are f also four satellite water reclamation plants located within the Basin which can provide ta, wastewater treatment and production of reclaimed water. The quality of the reclaimed water produced is suitable for most irrigation purposes. The TDS levels range from 800 *"" to 900 mg/l, and the chloride level averages 174 mg/l. t» The study reports that reclamation and water reuse in the Encina Basin are regulated by ** the San Diego RWQCB, who determines the water quality objectives for the Basin and *•» establishes the requirements for effluent discharge. The Encina Basin water quality objectives allow for use of reclaimed water throughout most of the Basin without demineralization. «M» r* Potential markets for reclaimed water in the Encina Basin include agricultural irrigation, ^ landscape irrigation and industrial use. The study estimates that 3,900 acres of *" agricultural area could be served with 7,800 AF/YR of reclaimed water. The potential for — reclaimed water use for approximately 2,200 acres of landscape irrigation is ^ approximately 5,700 AF/YR. Industrial use of reclaimed water includes the potential trash to energy plant in San Marcos and the SDG&E power plant in Carlsbad. These ** markets could potentially use 1,400 AF/YR of reclaimed water. fc, The water reclamation facilities available to produce reclaimed water include the Encina r WPCF (22.5 mgd), the Buena Sanitation District's (BSD's) Shadowridge WRP (1 mgd), *• the VWD's Meadowlark WRF (2.0 mgd), the LCWD's Gafner WTP Reclamation Plant (0.75 mgd), and the City of Carlsbad Lake Calavera Hills WRP (1.2 mgd).iP* lw The study recommends upgrades to the Encina, Gafner, Shadowridge, and Lake p Calavera Hills plants to provide the highest level of treatment required for unrestricted 1^ use of reclaimed water. For the Encina WPCF, it is proposed to provide this level of treatment for 2 mgd only. Interconnection of the reclaimed water transmission systems » is also proposed so that a reclaimed water network could be formed. Also the construction of pumping facilities would be required to provide reclaimed water to the proposed markets. The preliminary cost estimate for the proposed capital *• improvements is $9,625,000. Approximately $5,341,000 of this cost is estimated to be the cost required to add reclamation components to the existing plants. 3-9 m m 3.2.5 Aviara Reclaimed Water Facilities Plan ** In May 1989, Luke-Dudek completed the Aviara Reclaimed Water Facilities Plan for the City of Carlsbad. The report was prepared to serve as the first step toward obtaining a *"* State low-interest loan for water reclamation facilities to serve the Aviara development. ^ Aviara is located in Southwest Carlsbad. IP*The study describes the proposed master plan land use as a 1,400 acre mixed-use ** development with commercial uses, residential areas, a country club and 18-hole golf IP. course, a restaurant, and a resort hotel. Since a major element in the development of a ^ new source of water such as reclaimed water is evaluating existing water issues, the study presents a discussion of water supplies, water use trends, water quality, and water «- prices. •» The study provides a brief discussion of the regional wastewater collection treatment and ** disposal systems and specifically addresses the VWD's Meadowlark WRF and the «• Leucadia County Water District's Gafner WTP. The Meadowlark and Gafner plants have a potential to produce 1.6 mgd and 0.6 mgd of reclaimed water; however, Gafner WTP "* would require an upgrade to provide coagulation/flocculation, filtration, and extended ** chlorination required to produce reclaimed water for unlimited uses. The regulatory requirements for reclaimed water use described in the report include the ** Basin Plan by the RWQCB and Title 22 requirements established by the State ^ Department of Health Services (DHS). Landscape irrigation water quality consideration such as salinity, boron, nitrogen, and suspended solids are also discussed. *» The irrigation demand for the study was determined to be 1,215 AF/YR with a peak ^ summer demand of 4,020 gpm. *" The analysis of seven alternatives resulted in a recommended project consisting of a 16- *> inch delivery pipeline connecting to the existing Meadowlark failsafe pipeline, a 380 horsepower (Hp) distribution pump station, a 1.41 million gallon storage reservoir, a *"" pipeline to serve as the backbone of the distribution system. The report estimated the ** construction costs for the backbone pipeline of the distribution system would be ^ $1,618,000 and $1,576,000 for the delivery system. i* Project funding for the proposed facilities include a State low-interest loan for capital P. costs and revenues from the sale of reclaimed water and subsidies received from the te Metropolitan Water District (MWD) would provide money for the operation and maintenance of the system. Several financial analyses were performed by varying the «•» primary policy of reclaimed water. The analysis showed that a reclaimed water price set •» at 90 percent of the retail price of potable water result in a high positive present worth, a positive year-end-balance within a few years and provide an economic incentive for the *"* reclaimed water user and funds as necessary for the replacement of facilities in the » future. 3-10 The study concluded by recommending steps to be taken to obtain a State low-interest State loan for the reclamation facilities and to implement the findings in the facilities plan. The CMWD has prepared the loan application to the State and the application is now under review. 3.2.6 Encina Basin Facilities Plan In August 1988, the San Diego County Water Authority (CWA) authorized the preparation of the Encina Basin Water Reclamation Project - Phase I Facilities Plan (Encina Basin Facilities Plan). This study, prepared by John S. Murk Engineers, was funded by the CWA, BSD, City of Carlsbad, Carlsbad Municipal Water District (CMWD), LCWD, Olivenhain Municipal Water District (OMWD), San Dieguito Water District (SDWD), and the VWD. the facility planning efforts of this study are the outgrowth of the Encina Basin Feasibility Study. The report assesses major potential users of reclaimed water. The potential reclaimed water use areas include golf courses, agricultural enterprises, parks, and other landscaped areas. In the report, the list of potential users is refined to a list of seven candidate users by considering such factors as quantity of reclaimed water needed by the user, immediacy of need, potential for long term use, and utilization of existing facilities. The report presents alternatives and subalternatives based on serving various combinations of users and the concept of the demand system meeting the needs of a limited number of users or meeting the needs of an expanded number of users by using reclaimed water supplemented with potable water during periods of peak use. For facilities planning, a 10-hour delivery schedule is proposed, along with 75 pounds per square inch (psi) pressure at the point of metering the reclaimed water flow into the user's system. The Meadowlark, Gafner, and Shadowridge plants are the potential sources of reclaimed water. Screening of subalternatives using a combination of quantitative and qualitative criteria resulted in the recommended alternative which uses potable water supplementation of the reclaimed water supply to meet the needs of five users. The projected reclaimed water use for Aviara, La Costa Resort Hotel & Spa, Interstate 5, Frazee Flowers, and Okegawa Farms is 2,354 AF/YR. The facilities required at the Meadowlark reclamation plant include a new effluent screening facility at the Mahr Reservoir, additional effluent pumps, and a new force main from the plant to the reservoir. The facilities required at the Gafner treatment plant include new tertiary treatment facilities and a new effluent pump station and force main. On-site facilities include storage reservoirs with potable water connections and on-site pumps to feed the user's system. The existing Meadowlark failsafe pipeline will supply reclaimed water by gravity to users tributary to the line. Diversion structures and supply pump stations will pump reclaimed water from the failsafe to the on-site storage reservoirs from where it is pumped for use. The 3-11 ** potable water supply connection will automatically open to supplement the needs of the on-site pumps. The user's storage reservoirs served by the Gafner WTP will be filled by "* pumps located at the plant and via the existing 12-inch Gafner failsafe pipeline. Because ** the effluent from the Shadowridge treatment plant enters the Meadowlark WRF failsafe pipeline, it must be chlorinated to comply with minimum Title 22 requirements. 111 Appropriate monetary factors, such as cost indices, cost of money parameters, and the p useful life of project components are presented in the report. The report presents an ll economic analysis to determine the viability of the recommended project on monetary terms. The net present cost of the recommended alternative is $234/AF which is IP relatively low compared to $840/AF, the actual cost to develop alternative water for the IB Encina Basin. Also a financial plan and revenue program is developed which ensures sufficient revenue to support the project throughout its useful life. m Hm The initial action in implementing the project described in the report is to obtain firm commitments from the proposed users. A two step process, being acquisition of Letters m of Intent and negotiation of an agreement for the terms and conditions of the supply and *» use of reclaimed water, is suggested. Additional issues to be addressed include development of an operations plan, establishment of funding mechanism and agency, *** and the development and acceptance of standards to be used. ^ Agreements will also be needed for the water purveyors in the service area for distribution of reclaimed water, the Vallecitos Water District, and the Olivenhain Municipal ** Water District, these agreements will focus on the distribution of reclaimed water within ^ the service area of the other water districts. •H Table 3-1(«•» *» Water Reclamation Reports and Studies MM* M Report or Study Date IP L Overview of Wastewater Reclamation Opportunities, Lowry & Associates March, 1978 Preliminary Design Report, Reactivation of Existing LCWD Reclamation January, 1979 System, Engineering Science, Inc.m City of Carlsbad Wastewater Reclamation Master Plan Study, Lowry & September, 1979 P1 Associates Hi Environmental Impact Report for the City of Carlsbad Wastewater September, 1979 p Reclamation Master Plan, RECONn Environmental Impact and Facilities Plan for a Satellite Sewage Treatment 1980 _ Facility 3-12 p m Table 3-1 Water Reclamation Reports and Studies (continued) Report or Study Date f to Proposed Revision Basin Plan Objectives, Carlsbad Hydrographic Subarea, Luke-Dudek Civil Engineers Proposed Revision Basin Plan Objectives, Carlsbad A Portion of the Agua Hedionda Hydrographic Subarea, Luke-Dudek Civil Engineers Preliminary Design Report, Forest R.

Water supply facilities and water use trends will determine the availability of water. Water quality will establish the suitability of reclaimed water for reuse. This Chapter presents a discussion of water sources, water use trends, water quality, and water prices. 4.2 WATER SOURCES Potable water delivered to the vicinity of the City of Carlsbad is supplied through a vast delivery system of the State Water Project and the Colorado River Aqueduct by the Metropolitan Water District of Southern California (MWD) and the San Diego County Water Authority (CWA). The following description of water transmission, treatment, storage, and distribution facilities is provided as a basis for defining the roles of the various water agencies involved in supplying potable water to the study area. This section also includes a discussion of local water supply sources. 4.2.1 Regional Water Supply Regional water supply facilities discussed below include State Water Project facilities, MWD, and CWA facilities. 4.2.1.1 State Water Project At present, the State Water Project facilities consist of a series of dams, reservoirs, and aqueducts that deliver water through contracts to water service agencies in the Feather River area, the San Francisco Bay area, the San Joaquin Valley, and Southern California. Total water contracts call for the ultimate delivery of 4,230,000 acre-feet (AF) of water annually from the State Water Project, but the presently constructed facilities have an estimated firm yield of only 2,300,000 acre-feet per year (AF/YR). The firm yield will decrease in the future as demand increases in Northern California. Current water planning by of the California Department of Water Resources (DWR) has focused on two projects to help meet the State's water needs. The capacity of the State Water Project has been proposed to be expanded by the construction of the 1.25 million AF Los Banos Grande Reservoir in Merced County and the enlargement of the pumping plant that transfers water from the Delta to the California Aqueduct. 4-1 4.2.1.2 Metropolitan Water District The MWD was organized in 1928 and is restricted to the production, transportation, and distribution of water for municipal and domestic purposes. In 1941, MWD completed construction of the 242-mile long Colorado River Aqueduct and distribution system. Facilities for the expansion of the capacity of the main aqueduct to 1,200,000 AF/YR were completed in 1960. In 1960, the MWD entered into a contract with the DWR for an annual initial delivery of 1,500,000 AF from the proposed State Water Project. This amount was to increase beginning in 1972 to an eventual delivery maximum of 2,011,500 AF/YR by 1990, primarily to offset the loss of Colorado River water to Arizona due to a U.S. Supreme Court decision in 1964. The MWD's Colorado River right was decreased in 1985 from 1,212,000 AF/YR to 550,000 AF/YR when the Central Arizona Project went into operation. However, the MWD has first priority to 662,000 AF/YR of any water apportioned to California in excess of its basic 550,000 AF apportionment. The MWD's firm supply from both sources (the Colorado River Aqueduct and the State Water Project) will be 1,970,000 AF/YR in 1987 and is anticipated to decrease to 1,390,000 by the year 2000 unless additional measures and facilities are initiated. Demand for imported water is expected to increase from 1,600,000 AF to 2,010,000 AF during the same period. The MWD presently has five pipelines providing service to the CWA. The MWD's jurisdiction of these lines end at a delivery point approximately six miles south of the Riverside-San Diego County line at which point the CWA takes over. 4.2.1.3 San Diego County Water Authority The CWA delivers raw and treated imported water to its 24 member agencies which, in turn, supply almost 95 percent of the population of San Diego County. The CWA is governed by a Board of Directors consisting of at least one director from each member agency with additional directors appointed in proportion to the assessed valuation of property within each agency. The distribution system of the CWA consists of the extension of the aqueducts from the Metropolitan Water District delivery point to the member agencies throughout the County. The CWA operates the aqueduct system to deliver both raw and treated water; the primary treated water source being the Skinner Filtration Plant owned and operated by the MWD. Some treated water is purchased from local treatment plants within San Diego County for delivery to other member agencies. 4-2 4.2.2 Retail Water Suppliers The study area is under the jurisdiction of the Carlsbad Municipal Water District (CMWD), the Vallecitos Water District (VWD), and the Olivenhain Municipal Water District (OMWD). The CMWD, which serves over 85 percent of the City of Carlsbad, was originally formed in 1954 and has been known as both the Carlsbad Municipal Water District and the Costa Real Municipal Water District. In 1954, it joined the regional wholesaling agencies, namely the CWA and the MWD. The CMWD became a subsidiary of the City of Carlsbad in January 1990. The CMWD encompasses just over 20,000 acres almost entirely within the City of Carlsbad, and presently serves an estimated population of 41,600. OMWD and VWD serve approximately 15 percent of Carlsbad's water needs. OMWD was formed in April 1959 and joined CWA shortly after that. OMWD serves 3,511 customers. The VWD was formerly San Marcos County Water District and became VWD May 1, 1989. VWD is currently serving 660 customers over 897 acres in the City of Carlsbad. These service areas are shown in Figure 4-1. The future service area population is projected to be 109,000 at build-out. For all the Districts, 100 percent of their water supply is imported. The CMWD water is treated by the MWD at the Lake Skinner Filtration Plant. The CMWD currently has an average demand of 14,000 AF/YR with peak daily supply flows as high as 35 cubic feet per second (cfs), or about 70 AF per day. The CMWD has 38 million gallons (MG) or 117 AF of operational and short term emergency storage in tanks and 196 MG, or 600 AF of long term storage in the open, unlined Maerkle I Reservoir. These quantities are equivalent to 15 days of emergency storage. Proposed plans for a Maerkle II Reservoir would provide either 800 AF of storage with a treatment plant or 1,100 AF of the long-term storage objective of 5,250 AF with the remainder provided by the CMWD participating in the OMWD's proposed Mount Israel Reservoir Project. 4.2.3 Local Supply Local water supply within the San Diego Region comes from surface waters, groundwater, and reclaimed water. Local water supply within the San Diego Region including that from area reservoirs is considered to provide a dependable yield of 50,000 AF/YR; however, in extreme drought years this amount may be decreased by one half. The local water supply that is potentially available in the future could increase with the development of additional local storage. All major drainage areas in San Diego County contain small groundwater basins. These subsurface reservoirs are of limited size and subject to overdraft conditions and local quality deterioration. None of the surface water or groundwater sources in the area are used in the public water system; however, Carlsbad continues to maintain its water rights 4-3 to in the San Luis Rey River and there is a potential for utilization of that well field. The City of Carlsbad also has ownership of a well field in the Agua Hedionda Creek. The water ** from this supply is highly mineralized and has not been used in the public water system *• since 1958. r 4.3 WATER USE TRENDS <M The steady industrial and urban development in the study area has resulted in an f increase in residential and industrial/commercial water use and a decrease in agricultural water use. This section presents historical water use along with projected pi water use which identify the long-term demands on major conveyance and distribution y facilities. pi 4.3.1 Historical Uses to At the inception of the CMWD, urban area and irrigated agriculture was the predominant <" land use activity. Since the middle 1960's vast residential and commercial developments Im have resulted in the substantial reduction of irrigated agriculture by the conversion of the land uses. Table 4-1 shows the historic water uses for the District. For the Costa Real m Municipal Water District Master Plan for Public Water System, February 1985, water ** meter records from July 1979, through June 1982, were reviewed for all classes of use. The findings are summarized below. ^ Industrial water uses varied considerably; records varied from approximately 100 „» gallons per acre per day (gad) to over 6,000 gad. Based on individual industrial uses in the district, other agency values, and similar development uses, the master plan study used 3,000 gad for the industrial areas and 2,000 gallons per minute (gpm) for the *- Palomar Airport Business Park. ttw In commercial areas, the demands differed according to use. Meter records in the City *"* of Carlsbad service area indicated 980 gad for automobile retail sales, 840 gad for m intensive regional retail, 2,910 gad for restaurants, and 3,360 gad for motels. For agricultural areas, meters were reviewed for several areas. In general, the results *"" indicated demands less than what is normally considered necessary. The meter records *• varied according to crop. Since tomatoes were the main crop within the area, the Master ^ Plan Study used 2,500 gad, the water requirement for tomatoes. For freeway landscaping, records for three years averaged 2,640 gallons per day (gpd) per 1,000 1* feet of freeway. The highest-use year was four to ten percent higher than the average; m therefore, the Master Plan used 2,900 gpd per 1,000 feet for the study. Estimates for m school landscape requirements and water uses within school buildings were 1,840 gad for elementary schools, 2,215 gad for junior high schools, and 2,190 gad for high *» schools. 4-4 LEGEND 4000 8000 FT.

The estimated annual water demand for the City of Carlsbad is 25,600 AF for the year 2000 and nearly 44,000 AF at ultimate build-out which is expected to occur after 2010. A knowledge of water use variations in systems serving urban customers is important in projecting future demand. Invariably short term demands can greatly exceed the average annual rate. Monthly and daily peaking factors are generally found to be in the range of 110 to 160 percent and 150 to 220 percent of the average rate, respectively. The CWA estimates CMWD's peak month factor at 1 .5. The peak week for the CMWD has been determined by CWA to be at a rate 1.7 times the annual average daily demand. When the peak hourly demand is applied to the peak day demand, an annual peak hour factor, in terms of annual daily demand, of 2.7 results. 4.4 WATER QUALITY The quality of water supply in the study area generally determines its use. High quality imported water serves as the potable water source for the CMWD. Groundwater and surface waters are not used as a water source for the public water system, and the quality of these sources is not discussed. The MWD has an objective of serving a blend of 50 percent Colorado River water and 50 percent State Project water to reach a maximum total dissolved solids (TDS) level of 500 mg/l. The average TDS of the Colorado River at Lake Havasu has declined from 700 mg/l in fiscal year 1982-83 to 540 mg/l in June 1986, the lowest in 22 years. The average TDS for the east branch of the State Water Project was 275 mg/l. 4-7 * m Pin The quality of imported water supplied from the Skinner Filtration Plant to the CMWD is indicated in Table 4-3. As shown in the Table, 29 percent of the water that is supplied to CMWD is from the State Water Project. 4.5 HISTORIC AND FUTURE WATER PRICES Table 4-4 provides a summary of past, current, and projected CMWD retail water rates.

This Chapter provides a brief description of the regional wastewater collection and disposal systems. Wastewater flows and qualities of these treatment plants are also presented in this Chapter. 5.2 WASTEWATER AGENCIES AND FACILITIES There are many agencies providing wastewater collection and treatment services in the City of Carlsbad study area. Figure 5-1 shows the jurisdiction of these wastewater agencies and the location of the existing treatment plants. This section discusses the Vallecitos Water District (VWD) Meadowlark Water Reclamation Facility (WRF), the Leucadia County Water District's (LCWD) Forest R. Gafner Wastewater Treatment Plant (WTP) and, the City of Carlsbad Lake Calavera Hills Water Reclamation Plant (WRP). This section also describes the Encina Joint Powers Agency (JPA) and its regional facilities as they concern the study area reclamation planning. 5.2.1 Regional Facilities The Encina JPA consists of the Cities of Carlsbad and Vista, the VWD, Encinitas Sanitary District (ESD), Buena Sanitation District (BSD), and LCWD. These six agencies own and operate the Encina Water Pollution Control Facility (WPCF). Each agency owns a certain percentage of the treatment plant with a certain treatment capacity right. The facility was placed in operation in 1965 at a rated capacity of 4.5 mgd. After several expansions and additions, the plant has been upgraded from primary treatment to secondary treatment with a capacity of 22.5 million gallons per day (mgd). The Encina WPCF serves as a regional wastewater treatment and disposal facility for a service area encompassing approximately 120 square miles and a population of approximately 205,000, with 100,100 customer accounts. The WPCF also treats sludge from four upstream plants and wastes from septic tanks and chemical toilets for the northwestern portion of San Diego County. 5.2.1.1 Existing Facilities Current wastewater treatment at the Encina WPCF produces secondary effluent plus stabilized and dewatered sludge. The Encina WPCF consists of three parts - the 5-1 '*» wastewater treatment plant, the sludge disposal system, and the effluent disposal/reuse system. A schematic of the wastewater system at Encina WPCF is shown in Figure 5-2. """ The WPCF's operating components vary widely in flow capacity, due to the nature of ** individual processing operations, the number of existing units per processing operation, m and the quality and quantity of wastewater inflow. The nominal plant capacity for liquid wastewater treatment currently is estimated as 22.5 mgd. Although many of the WPCF's i<t existing operation units are capable of processing a greater capacity, the designation of M overall plant capacity reflects the limitations of individual wastewater processing units. '^ The quantity of wastewater treated at the WPCF currently averages 19.5 mgd, or nearly 87 percent of the nominal rated capacity. P» * 5.2.1.1.1 Wastewater Treatment Plant ^* At the Encina WPCF, raw wastewater from the interceptor sewers and sludge from l» upstream reclamation plants are combined and channeled to preliminary treatment which consists of grit removal and primary sedimentation. In the primary treatment ** tanks, suspended material in the wastewater is allowed to settle out. The settled *" material, primary sludge, is removed to the digesters while the liquid effluent flows to the secondary treatment facility. *" In secondary treatment, the primary effluent is mixed with bacteria and aerated to P. remove dissolved organic material. The resulting "mixed liquor" then flows into secondary clarifiers where the bacteria is allowed to settle out. The secondary sludge is either recirculated to the aeration tanks or removed for sludge thickening and eventually f is sent to the digesters and is combined with primary sludge. The sludge treatment ^ facility consists of sludge thickening equipment and four digesters to stabilize the sludge anaerobically. f* *. The chlorination facility/effluent pump station consists of chlorination equipment, a chlorine contact chamber where the chlorine contact chamber disinfects some of the "" wastewater, and effluent pumps and pipelines which convey the effluent to the ocean m outfall systems. "" 5.2.1.1.2 Sludge Disposal m The sludge disposal system consists of belt filter presses and a loading facility to convey ^ the dewatered sludge to trucks for disposal or reuse. Sludge is presently trucked either to a local county landfill or to a contractor who provides sludge reuse services. The m facility is designed to accommodate anticipated sludge volume up to an equivalent solids m flow of 27.9 mgd. It is anticipated that this treatment volume will be sufficient until 1992, at which time an expanded facility should be operating and available to accommodate ** increased sludge volume. 5-2 ENCINITAS SANITATION DISTRICT CARDIFF SANITA LEGEND 4000 8000 FT.

The Encina regional ocean outfall, originally constructed in 1965, has been extended and enlarged to a working capacity of 40.5 mgd peak wet weather flow with one pump in operation. The outfall has the flexibility to be expanded to a maximum capacity of 65.0 mgd. The WPCF reuses approximately 4 mgd daily for such uses as landscape irrigation, process water, and for plant cleanup and washdown. 5.2.1.2 Encina Expansion Project The Encina JPA has proposed to expand the WPCF from the current liquid wastewater treatment capacity of 22.5 mgd to 36.0 mgd and the current equivalent solids capacity of 27.9 mgd to 38.0 mgd in order to meet projected increases in population and corresponding wastewater treatment demand within the Sewer System service area. The Expansion Project will be located within the existing 25-acre plant site, which includes vacant and previously graded areas designed to accommodate new facilities. In addition to onsite treatment improvements, the Expansion Project includes the installation of a third and fourth effluent pump, the construction of an interim flow equalization structure, and improvements to the solid waste (sludge) treatment system. The installation of a third and fourth effluent pump has been determined to be necessary for reliable discharge of both existing and projected peak outfall flows. Construction has started on the Expansion Project, which is estimated to cost $47,688,000, including a contingency of $3,120,000. In major construction projects such as the Expansion Project, completion of construction on time and within cost estimates is dependent upon, among other things, the owners providing on a timely basis the funds necessary to construct and place such projects in operation. An estimated 59 percent of the cost of construction of the Expansion Project will be funded with a portion of the proceeds of bonds. ESD, LCWD, and VWD will each provide an equity contribution of 3 percent, 12 percent, and 26 percent, respectively, to the construction cost of the Expansion Project. Construction permits for the Expansion Project were issued by the City of Carlsbad in September, 1989. The Encina JPA has completed and certified an environmental impact report and has received a Coastal Development permit from the Coastal Commission. The Encina JPA presently holds and maintains permits to operate three engine/generators and two engine/blowers which form the power source of the Encina WPCF cogeneration system. The Encina JPA has applied for and received a permit to construct certain emissions control equipment to further decrease the discharge of air- borne pollutants to the atmosphere. This equipment will be installed concurrent with the Expansion Project. 5-5 Other permits held by the Encina JPA include a NPDES permit issued jointly by the P Environmental Protection Agency (EPA) and the RWQCB. The Encina JPA maintains *» permits for the Encina WPCF's underground fuel storage tanks, a license from the Federal Communications Commission to operate the Encina WPCF's radio system and !* various permits issued by the State's Department of Occupational Safety relating to •* certain portions of the Encina WPCF. **»i 5.2.2 Vallecitos Water District's Meadowlark Water Reclamation Facility p The VWD owns and operates the 2.0 mgd Meadowlark WRF which was constructed in la 1982. The Meadowlark WRF is located just west of Rancho Santa Fe Road adjacent the San Marcos Creek. The facility provides wastewater treatment for a population of f» approximately 30,000 within the District's service area. The treatment plant is equipped m with sufficient secondary and tertiary treatment facilities to meet DHS's, Title 22 requirements for unrestricted reclaimed water use. P» in Wastewater flows that are diverted to the Meadowlark WRF are pumped from the influent pumping station to rotary screens which remove solids ahead of the rotating biological P contractors. The screenings are carried to the solids pumping station. Two trains of ^ rotating biological provide biological treatment to the wastewater, and are designed for a biochemical oxygen demand (BOD) removal rate of 90 percent. Effluent from the rotating biological contractors flows to the final sedimentation tanks. Floating material is ** mechanically skimmed from the surface of the water by flight collectors and carried to «. the solids pumping station. In the final sedimentation tanks, solids settle to the bottom to and a portion is returned to the rotating biological contractors as return sludge with excess sludge wasted to the solids pumping station. *•* to Rapid mixing with a mechanical mixer followed by slow mixing by means of channel aeration allow for low level additions of alum and polymer. After chemical addition, the *" secondary effluent is conveyed to two dual media filters. The filter backwash flows to a *• storage tank and is then either pumped to the final sedimentation tank or wasted to the solids pumping station. Chlorine is mixed with the effluent by means of a mechanical """ mixer. Two hours of chlorine contact are provided in a baffled chlorine contact tank. (Ml Following chlorine contact, the effluent is either pumped directly to the Encina regional ocean outfall, or pumped approximately 4,000 feet to the 54 million gallon Mahr Reservoir. From either the reclamation facility or the reservoir, the effluent is disposed «. through the fail-safe pipeline to the Encina regional ocean outfall or to the La Costa Golf ^ Course. The 12-inch ductile iron fail-safe pipeline extends from the effluent storage reservoir north along Rancho Santa Fe Road, across to El Camino Real, and then n«» parallels Camino Vida Roble. The pipeline size increases to 16-inches at the intersection to of Yarrow Drive and Camino Vida Roble. The pipeline continues to the Encina regional ocean outfall, paralleling Palomar Airport Road and then Interstate 5. The fail-safe *" pipeline bisects the study area. 5-6 Screenings, skimmings, wasted sludge, and wasted backwash is transferred from the solids pumping station the to the Encina WPCF via the land outfall for treatment. Design criteria for the Meadowlark WRF are listed in Table 5-1 and a treatment process schematic is shown on Figure 5-3. The Meadowlark WRF plant was designed for an ultimate expansion to 5.0 mgd. The draft master plan for the VWD presents several alternatives including expanding the Meadowlark WRF, constructing a new treatment plant, or some combination of expanding the Meadowlark WRF and constructing a new treatment plant. The draft master plan has not been adopted at this time, therefore there are no specific plans to expand the plant at this time. 5.2.3 Leucadia County Water District's Forest R. Gafner Wastewater Treatment Plant The Forest R. Gafner WTP was constructed in 1962 and provides secondary treatment for portions of the communities of Carlsbad and Encinitas. The treatment plant is located north of La Costa Boulevard just east of El Camino Real. The plant was temporarily taken out of service after the Leucadia County Water District joined the Encina JPA in 1975, but has been operating since 1979. During its initial operation period the Gafner Plant provided reclaimed water to irrigate the La Costa Golf Course. The plant service area includes only a portion of the LCWD; most District flows are pumped to and treated at the Encina WPCF. The process units at the Gafner Plant include a bar screen and comminutor, primary clarifier, trickling filter, secondary clarifier, and a chlorine contact chamber. The facilities also include an 800,000 gallon onsite reservoir to equalize the final effluent prior to being pumped and discharged through the fail-safe pipeline to the Encina regional ocean outfall. The screenings and secondary sludge are discharged to the Encina WPCF for further treatment and disposal. A treatment process schematic of the Gafner Plant is presented on Figure 5-4, and pertinant design data for the major unit processes are given in Table 5-2. The Gafner WTP is operating near its capacity of 0.75 mgd. The capacity of the plant was originally intended to be expanded to 1.5 mgd. To provide reclaimed water for unlimited irrigation uses, the Gafner WTP would require an upgrade to provide coagulation/flocculation, filtration, and extended chlorination. The LCWD has qualified for a State low-interest loan for these upgrades. 5.2.4 Lake Calavera Hills Water Reclamation Plant The Lake Calavera Hills Water Reclamation Plant (WRP) was constructed to provide wastewater treatment for the Lake Calavera Hills Master Plan Community and other developments east of El Camino Real in the proximity of the Calavera Development. The 5-7 m plant was originally conceived as a reclamation facility, but until 1989 had never been operated. Major construction and a substantial expenditure of funds would be required ** to make the plant operational, as a reclamation plant meeting the most stringent Title 22 ** treatment standards. "* The plant was completed in 1981 and turned over to the City of Carlsbad for operation * and maintenance. The plant is now owned by the City of Carlsbad and all future m upgrades and all costs for operation and maintenance of the plant will be borne by the i City of Carlsbad. The feasibility of using the Lake Calavera Hills WRP as a source of reclaimed water to serve the markets identified in this Master Plan was studied further. m The results of this feasibility study are included as Appendix H. IB The original service area for the plant has been modified. When the plant was * conceived, most of the northeast quadrant of the City of Carlsbad was served by this w plant. The June 1984 master plan recommended including only the Lake Calavera Hills Planning Area in the plant's service area. m ll There are a number of unit processes involved in the treatment train in the Lake Calavera Hills WRP. These processes include comminution, aeration, clarification, chlorination * and solids handling. The Lake Calavera Hills WRP is designed to treat 1.2 mgd of sewage utilizing the . oxidation ditch process. The plant was designed with chlorine contact tanks, aerobic l* digesters and solids handling facilities. The plant is also equipped with stand-by power. p. Table 5-3 provides a description of the major process units, their size and their , capacities. Figure 5-5 shows the schematic of the treatment plant processes. •» The headworks of the plant consist of two open channels. One of these channels to contains a comminutor and the other contains a stationary, manually cleaned trash rack. The capacity of each channel is 2 mgd. All flow is normally routed through the *» comminutor the manually cleaned bar rack is used as an emergency bypass. The (to purpose of the comminutor is to grind up large objects which may enter the sewer system and cause damage to other elements of the treatment system. ^ The Lake Calavera Hills WRP is an extended aeration plant utilizing the oxidation ditch process. The oxidation ditch process utilizes oval tanks to provide both primary and secondary treatment to the wastewater. Oxygen is introduced into the tanks by the use * of brush aerators. Each tank has two brush aerators. The tanks are designed with a P, detention time of 24.9 hours and have a BOD loading rate of 2,500 pounds per day. L. Flow from these tanks is sent to the clarifiers. 5-8 Table 5-1 Meadowlark Water Reclamation Facility Design Summary Sewage Flows Design flow Initial flow Ultimate flow Design BOD Design suspended solids Influent Pumping Structure and piping designed for ultimate flow Variable-speed pumping First stage pumps Ultimate pumps Influent Screens Rotary screens with .020 inch openings First stage Ultimate Rotating Biological Contractors Design BOD, influent Design BOD, effluent Number of shafts Number of stages Area of media Loading rate Final Sedimentation Tanks Overflow rate First stage Ultimate Tank dimensions Chemical Feed System Alum dosage Polymer dosage 2.0 mgd, average; 3.6 mgd, peak 0.25 mgd, average; 0.5, peak 5.0 mgd, average; 9.0 mgd, peak 250 mg/l 250 mg/l One pump standby 2 -1150 gpm @ 25 ft.

ASSOCIATES, INC. 6-14 P it In The clarifiers at the plant provide the final unit process for the liquid stream to chlorination. The clarifiers separate the aeration tank effluent into a solid stream and a ** liquid stream. The liquid stream is sent to the chlorine contact facilities and the solid to stream is either sent back to the oxidation ditch process or to the solids processing train. The clarifiers have an overflow rate of 400 gallons per square foot per day and a m designed detention time of 4.5 hours at average flow.«• The chlorine contact chamber has a volume of 43,000 gallons and provides for a detention time of 30 minutes at peak flow. This facility is not heeded for ocean discharge m but would be needed for reclamation. P m The clarifier underdrains are connected to three pumps. These pumps can either be used to return solids to the aeration tanks or to send them to the aerobic digester. M Solids are normally returned to the aeration tanks as part of the secondary treatment U process. In order to prevent an accumulation of solids in the aeration tanks, solids are routinely wasted to the aerobic digester. p Hi The aerobic digester has a volume of 75,000 gallons, which provides for a liquid detention time of 25 days. The purpose of the aerobic digester is to stabilize the solids P prior to ultimate disposal. li The plant has a belt filter press capable of handling 25 gallons per minute (gpm) with anp approximate influent solids of 1.5 percent. It will output a minimum solids of 15 percent. 11 This process dewaters the digested sludge and reduces the volume which needs to be p. trucked to a landfill. This is the final sludge processing unit prior to disposal. (to The plant is equipped with a diesel engine generator set and fuel storage tanks to *- provide power to the plant in case of a power outage. 5.3 WASTEWATER FLOWS <m it The development and analysis of alternative reclamation plans requires the evaluation of wastewater quantities from each potential source of reclaimed water. Flow variations, " and both present and projected wastewater volumes for the Encina WPCF, the • Meadowlark WRF, the Gafner WTP, and the Lake Calavera Hills WRP are presented in this section.™ * 5.3.1 Flow Variations P*jy Diurnal variations in wastewater flows generally tend to follow a definite pattern with early morning and early evening peaks; however, no daily variations in influent occur at either P the Gafner WTP or at the Meadowlark WRF. Influent wastewater to the Gafner WTP If flows to the Leucadia Pumping Station wetwell from which it is pumped at a constant rate to the headworks. Flows to the Meadowlark WRF are also fairly constant. However, the ** Encina WPCF experiences peaking flows during the day. The largest peak occurs in the 5-16 m morning hour between 9:30 a.m. to 10:30 a.m. and reaches approximately 31 mgd, whereas the average flow is about 20 mgd.in B Seasonal variations in wastewater flows typically occur in resort areas, in small communities with college campuses, and in communities with seasonal commercial and ? industrial activities. Wastewater flow variation also occur because infiltration and inflow ™ quantities vary seasonally. Stormwater and groundwater can enter through cracks, p, joints, unauthorized drainage connections, and poorly constructed house connections. i^ The Meadowlark and Gafner plants do not experience seasonal variations since inflows are held fairly constant by diverting a portion of the wastewater flows to the Encina p WPCF. However, monthly flow records indicate somewhat higher flows during the wet ^ season and in the summer months, reflecting both infiltration/inflows and an influx of summer tourists. p • 5.3.2 Present and Projected Flows S Present and projected flows for the Encina, Meadowlark, Gafner, and Lake Calavera Hills plants are presented in Table 5-4. Currently, almost 0.70 mgd of wastewater is directed to the Gafner WTP. Flows in excess of this amount are pumped to the Encina WPCF; 1 however sometime in the future, the Gafner WTP may be operated at its current 0.75 " mgd capacity. The rated capacity of the Meadowlark WRF is 2.0 mgd. Since the current use of reclaimed water from the Meadowlark WRF is limited and it is more economical to E treat wastewater flows to only secondary levels at the Encina WPCF, only minimal flows are directed to the Meadowlark WRF. The average daily flow for the Meadowlark WRF p during June 1988 through September 1988 was 0.59 mgd. If the Meadowlark WRF is || expanded, the ultimate wastewater flows may be 5.0 mgd. The present capacity of the Encina WPCF is 22.5 mgd. Flow records for January 1989 and July 1989 indicate p average flows of 20.6 mgd and 22.7 mgd, respectively. The Encina WPCF was master m planned for 45 mgd. Although the Lake Calavera Hills WRP has a design capacity of 1.2 mgd, the Sewer Master Plan states that 0.88 mgd is the most that can reach the plant. P. Operational changes such as additional pump stations would be required to deliver the • projected wastewater flow of 1.20 mgd to the Lake Calavera Hills WRP. I 5.4 WASTEWATER QUALITY p The intended use of reclaimed water determines the level of treatment required to ^ achieve an acceptable effluent quality. The influent to both of these treatment plants is of domestic origin and is expected to remain of domestic quality. The Meadowlark WRF p provides tertiary treatment and the Gafner WTP provides secondary treatment. As m discussed previously, the Gafner WTP would require an upgrade of facilities to provide reclaimed water for unlimited uses. The probable effluent quality of the upgraded Gafner f» WTP would be approximately the same as the effluent from the Meadowlark WRF. The Li chemical and physical characteristics of the effluent from the Meadowlark WRF are presented in Table 5-5. 5-17 Table 5-4 Present and Projected Wastewater Flows m p m Pi p m P m m I E Pli P m P IP to p Hi 1. imm EncinaWPCF Meadowlark WRF Gafner WTP Lake Calavera Hills WRP Encina Water Pollution Control Wastewater Flows, mgd Present Ultimate 21 .7 1 45.0 0.59 * 5.0 3 0.61 4 0.75 0 0.88 5 Facility flow records, average for January 1989 and July 1989.

The governmental p> regulatory agencies require that wastewater be disposed of in a manner which will y protect health, maintain receiving water quality consistent with its beneficial uses, and prevent nuisance conditions in the disposal area. These requirements which determine P the degree and the type of treatment which must be provided prior to disposal or reuse, • are discussed in this Chapter. m 6.2 FEDERAL AND STATE INSITUTIONS AND REQUIREMENTSm The passage of the Federal Water Pollution Control Act Amendments of 1972, PL 92- 500, established the regulation of wastewater discharges on the basis of effluent quality m limitations. Section 301 of PL 92-500 set forth a timetable with the effluent limitations for m point discharges and required the Environmental Protection Agency (EPA) to further to define those limitations. «*• In California the Porter-Cologne Water Quality Act (Porter-Cologne Act) was enacted in fe 1969, and became Division 7 of the California Water Code and is included as Appendix B. It deals primarily with the control of water quality, but it also establishes California's — policy on the use of reclaimed water. It provides for the establishment and enforcement m of statewide reclamation criteria. *** California's policy on the use of reclaimed water is in Sections 13550 and 13551, Article m 7, of the California Water Code, titled "Waste Water Use", and is summarized here: "The legislature finds that the use of potable domestic water for the irrigation of m green belt areas, including cemeteries, golf courses, parks, and highway M, landscaped areas, is a waste of such water when reclaimed water which meets M the conditions, is available, and: P» a. The source of reclaimed water is of adequate quality and is available for m such use. f* b. The reclaimed water may be furnished to the greenbelt areas at a li reasonable cost. The cost of supplying reclaimed water shall be comparable to or less than, the cost of supplying potable domestic water. m P» pi li c. The use of reclaimed water will not be detrimental to public health. d. The use of reclaimed water will not adversely effect downstream water rights, degrade water quality, and not be injurious to plant life." "A person or public agency, including a state agency, city, county, city and county, district, or any other political subdivision of the state, shall not use water from any source of quality suitable for potable domestic use for the irrigation of greenbelt areas when suitable reclaimed water is available ..." as defined in the above section. 6.2.1 State Department of Health Services The State Department of Health Servicess (DHS) has established quality, treatment, reliability and operational standards for the reuse of reclaimed water. These regulations are contained in Title 22, Division 4 of the California Administrative Code (Title 22), and are intended to ensure that wastewater treatment facilities can reliably produce treated wastewater of adequate quality. Specific levels of treatment for various uses of reclaimed wastewater are shown in Table 6-1, and the section of Title 22 is included in Appendix C. Table 6-1 Treatment Requirements for Reclaimed Water Irrigation Maximum Allowable Coliform Count Reclaimed Water Use Level of Treatment perl 00 ml Orchards, vinyards, fodder, fiber and seed crops Surface irrigation of food crops Spray irrigation of food crops Pasture irrigation of milking animals Landscape irrigation of golf courses and freeway with restricted use Landscape irrigation of parks and schools with unrestricted use Primary Secondary Filtration1 Secondary Secondary Filtration No requirement 2.2 2.2 23.0 23.0 2.2 Filtration of wastewater requires secondary treatment followed by coagulation, clarification and filtration. The DHS requires that an engineering report be prepared containing a detailed design of the proposed reclamation system. The system must be operated so that all the reclaimed water receives adequate treatment prior to its point of use. A number of reliability features are specified in Title 22, including the following: 6-2 m • Alarm devices are required to warn of failure of any specified treatment process or of the normal power supply, P» m • Reclamation facilities must be provided with either a standby power source, short term retention or disposal facilities with standby replacement equipment, or long ** term storage or disposal provisions, and Ml • Primary treatment, biological treatment, secondary sedimentation, coagulation, filtration and chlorination processes must include either multiple or standby m treatment or process units or long term storage or disposal provisions. P» , In addition to the detailed engineering report, a contingency plan will be required to assure that no untreated or partially treated wastewater is used. Guidelines in Title 22 IP also describe the operational procedures to be implemented at the reclamation facilities. ta Sampling of effluent quality, including daily analysis for coliform and settleable solids, as well as monitoring of turbidity are required. Operating records and reports are required * to be completed and maintained to document all analyses and operational problems. If The DHS has also developed policies concerning the protection of groundwater quality m from potential adverse affects due to wastewater discharges. These policies reflect the ta concern of the DHS over the possibility that ingestion of reclaimed water produce long term health effects. In general, the policy of the DHS is that it will recommend against ** near term wastewater management plans which involve direct discharge of treated ** wastewater into a domestic water supply or plans which involve injection of treated m wastewater for groundwater replenishment. The DHS has two sets of guidelines for use in establishing restrictions for the waste m discharge requirements. These guidelines, entitled, Guidelines for Use of Reclaimed y Wafer for Irrigation and Impoundments and Guidelines for Worker Protection at Water Reclamation Use Areas, contain the DHS policies regarding the separation and p construction of domestic and reclaimed water mains, assurance of public health and it safety, spray irrigation, and impoundments. "• 6.2.2 Regional Water Quality Control Board m There are nine Regional Water Quality Control Boards (RWQCB) in the state, and each P operates under the general guidance and final authority of the State Water Resources • Control Board (SWRCB) and EPA. The City of Carlsbad is located within the jurisdiction m of the San Diego RWQCB. The RWQCB is authorized by the Porter-Cologne Act to i apply and enforce the reclamation criteria established by the DHS. pi The RWQCB issues State Waste Discharge Requirements to agencies producing Ig reclaimed water, such as the Vallecitos Water District and Leucadia County Water District, and which discharge treated wastewater to land (i.e., irrigation, percolation, «* groundwater recharge). The RWQCB issues federal National Pollutant Discharge . r 6-3 « Elimination System (NPDES) permits to agencies discharging treated wastewater to navigable waters of the U.S. (i.e., streams, lakes, lagoons, and the ocean). If an agency *"" discharges reclaimed water to a man-made pond, however, which is protected from ** overflowing to a natural water body, then State Waste Discharge Requirements are sufficient. wtt 1J 6.2.2.1 Report of Waste Discharge The procedure for processing and issuing Waste Discharge Requirements consists of ** the following steps: *• 1. the discharger describes the proposed disposal of wastewater in a document called "Report of Waste Discharge". This report contains the following information: M» m a. The design and operation of the treatment facility, m b. The discharge quality, *c. Demonstration that the RWQCB ground water quality objectives will not be m exceeded. This may require that salt or other constituent and water mass •• balance tests in the hydrologic subarea be performed, ** d. Demonstration that no surfacing of the reclaimed wastewater will occur 111 downstream of the development, ^ e. Description of measures which will be taken to prevent runoff and flooding, « f. Description of measures to be taken to exclude the public from the area, if te necessary, «"* g. Description of how the supplier of the reclaimed water will exercise control IP over its use, and a copy of any agreements made between the supplier, and*• ** h. Also required at this time is the final approved Environmental Impact Report or Negative Declaration. The discharger also has to describe ** storage facilities for use when the water may not be reused, such as during ^ wet weather. g 2. The staff of the RWQCB acts as a clearinghouse for the project. It sends the Report of Waste Discharge to the California Department of Fish and Game, the IP DHS, the SWRCB, the County Department of Health Services and other agencies m for review. Comments by these agencies are returned to the staff of the RWQCB and incorporated into the tentative Waste Discharge Requirements, 6-4 -* 3. The staff of the RWQCB drafts tentative Waste Discharge Requirements for the ^ project, *"* 4. The RWQCB submits the tentative Waste Discharge Requirements to the p, consulting agencies listed above in step 2, for review and comment. The RWQCB reviews the comments for possible inclusion in the requirements, and p. 5. The staff of the RWQCB presents the tentative requirements to the RWQCB at a I, public hearing for adoption. Once adopted, they are no longer considered tentative. PI *. In addition to obtaining a waste discharge permit, the following items must be completed and approved before discharge can commence:P» b 1. A design certification report containing an engineering analysis demonstrating that the facility will meet the waste discharge requirements, *• 2. An engineering report is submitted to the RWQCB and the DHS in accordance with Section 60323 of Title 22 of the California Administrative Code. The L guidelines for this report is included as Appendix D. This report contains an engineering analysis demonstrating that the facility will meet the requirements of m Title 22 and also a contingency plan assuring that no inadequately-treated to wastewater will be delivered to the use area. This report and the design certification may be combined, and P» to 3. Rules and regulation governing the design and operation of the facilities using reclaimed water are established by the discharger for each user. These rules are *~ developed in conformance with the DHS guidelines and the "Regulations Relating l» to Cross-Connections" contained in Title 17 of the California Administrative Code. The rules and regulations are submitted to the RWQCB and DHS.P» m The process for issuing water reclamation requirements is similar to that for issuing the waste discharge requirements except that the process is initiated by sending the L RWQCB a letter stating who the user will be, and if available, an agreement between the ** user and the discharger. The user must submit plans and specifications to the state and m county health facilities in place of the engineering reports specified above. If water y purveyor requirements are needed, the process for obtaining these is the same as for the water reclamation requirements. *» p The time required for the permitting process varies for different projects. The time allowed to the RWQCB to issue the permit is 120 days from the time the completed ** Report of Waste Discharge is received by the RWQCB. In practice, the waste discharge m requirements process typically takes three months and the water reclamation requirements process takes six weeks. 6-5 «* A procedure which may add considerable time to the permitting process is the preparation of the environmental impact report (EIR) for the project. The environmental *" impact evaluation procedure is usually conducted one time for each discharger. In the ** process, the environmental impacts associated with each of the users are considered. ^ As a result, when applying for water reclamation requirements, the user does not have to go through the environmental impact procedure again. If, however, a potential user m applies for water reclamation requirements that were not considered during the initial m environmental impact process, the environmental impact evaluation would have to be conducted. - 6.2.2.2 Existing Waste Discharge Requirements te Several Waste Discharge Permits related to this Master Plan have already been issued p» by the San Diego RWQCB. In May 1987, the San Diego RWQCB adopted ORDER NO. |» 87-87, WASTE DISCHARGE REQUIREMENTS FOR SAN MARCOS COUNTY WATER DISTRICT MEADOWLARK WASTEWATER RECLAMATION PROJECT, which established m the currently named Vallecitos County Water District as a wholesaler of reclaimed water to to the City, and permits the use of reclaimed water from the Meadowlark WRF to be used in certain portions of the City, including the areas including the Aviara and La Costa golf m courses.m Also in May 1987, the San Diego RWQCB adopted ORDER NO. 87-82, WASTE L DISCHARGE REQUIREMENTS FOR LEUCADIA COUNTY WATER DISTRICT FOREST R. GAFNER WATER RECLAMATION PLANT NEAR THE CITY OF CARLSBAD, SAN DIEGO _ CALIFORNIA. The Order states in its findings that up to 0.75 mgd of effluent from the ^ District's Leucadia County Water District (LCWD). Gafner Water Reclamation Facility will be used for the irrigation of the 250-acre La Costa Golf Course within the City. f* L New or modified Waste Discharge Requirements are required for any new and/or modified sources of reclaimed water, treatment methods or capacities, and reclaimed f water uses not already identified in the existing Waste Discharge Requirements identified <*• by the above orders. For example, if reclaimed water produced at the Encina WPCF were proposed for use at Aviara or the La Costa Hotel and Spa, the Waste Discharge *"" Reqirements for the Encina WPCF would need to be amended to regulate the disposal of '* treated wastewater in that method. #» 6.2.2.3 Water Reclamation Requirements P» To the users and purveyors of reclaimed water, the RWQCB issues a separate permit ^ termed Water Reclamation Requirements, which describe the-criteria and restrictions required for the safe use of the reclaimed water. to The process for issuing Water Reclamation Requirements is similar to that for issuing the Waste Discharge Requirements except that the process is initiated by sending the ** RWQCB a letter stating who the user will be, and if available, an agreement between the 6-6 "• user and the supplier. Other pertinent information can be used from the original Report of Waste Discharge provided the use area is identified and approved in that document. ** The user must submit plans and specifications of the proposed reclaimed water ** distribution facilities to the DHS and County Department of Health Services facilities via p. the RWQCB for system approval prior to use. Water Reclamation Requirements issued to public agencies as reclaimed water — purveyors must again have the proposed service area approved for application in the to original Waste Discharge Requirements issued to the producer of the reclaimed water. Water Reclamation Requirements for both water users and purveyors require the "* designation of a Water Master to be in charge of the irrigation system described in the M permit, and the preparation of Rules and Regulations for the safe use of the reclaimed water.*"• *» The process of obtaining Water Reclamation Requirements takes about six weeks, considerably less than the six months required for Waste Discharge Requirements. m 6.2.2.4 Existing Water Reclamation Requirements J" In January 1984, the San Diego RWQCB adopted ORDER NO. 84-10, WATER " RECLAMATION REQUIREMENTS FOR THE CITY OF CARLSBAD FOR THE m PPURVEYANCE OF RECLAIMED WATER IN SAN DIEGO COUNTY. The Order permits the m City to distribute within its boundaries reclaimed water produced by the Vallecitos Water District's (VWD) Meadowlark Water Reclamation Facility (WRF). F M Also in January 1984, the San Diego RWQCB adopted ORDER NO. 84-11, WATER RECLAMATION REQUIREMENTS FOR THE LA COSTA HOTEL AND SPA SAN DIEGO m COUNTY, which allows the use of reclaimed water from the Meadowlark Water ii Reclamation Facility for irrigation of the 36-hole La Costa Hotel and Spa Golf Course. T Thus, Water Reclamation Requirements are needed for each additional potential user of * reclaimed water in the City, and the San Diego RWQCB should be notified if reclaimed water from any source other than the Meadowlark WRF is to be used at the La Costa •L Hotel and Spa Golf Course. p* 6.2.2.5 Basin Plan Compliance m As part of its regulatory powers, the San Diego RWQCB has the responsibility for f* formulating and adopting long-range policies and objectives for water quality control b through the preparation of its Comprehensive Water Quality Control Plan Report, San Diego Basin 9 (Basin Plan). The Basin Plan identifies the water quality objectives If" necessary to protect the beneficial uses of receiving waters, both groundwater and to surface water, and describes the implementation program necessary to achieve these objectives. These water quality objectives and designation of beneficial uses of ground ^ and surface waters are listed according to hydrographic units, areas, and subareas in * the Basin Plan. 6-7 The City of Carlsbad is divided into several separate hydrographic subareas (HSAs) as "* shown in Figure 6-1. Each HSA has its own numerical water quality objectives and ** designated beneficial uses as defined in the Basin Plan. Those objectives and ^ designations are listed in Tables 6-2 and 6-3. ** State law requires that no discharge of treated wastewater, which includes reclaimed n water shall cause the established ground and surface water objectives nor established beneficial uses for any HSA to be degraded. To apply this law, the San Diego RWQCB requires that agencies discharging reclaimed water for irrigative purposes must treat the »- reclaimed water until its salt concentration, measured as total dissolved solids (TDS) in „, units of milligrams per liter (mg/l), either equals one-third the established numerical objective or meets the quality of the alternative water source for that irrigative use. m For example, if the numerical objective for TDS in a particular HSA in Carlsbad is 1,500 mg/l, and the existing water supply for irrigation to that HSA is imported water averaging m 550 mg/l TDS; then the San Diego RWQCB would require reclaimed water to meet the •» 550 mg/l TDS concentration for irrigation. Generally, reclaimed water quality has a TDS concentration of approximately 300 mg/l greater than the associated potable water * supply, and thus, varies between 850 to 1,100 mg/l in San Diego County. However, in ** some communities where the use of self-regenerating water softeners is high, _ wastewater TDS can go as high as 1,500 mg/l.^w 'm Fortunately, several of the HSAs in Carlsbad have had their numerical objectives p substantially relaxed by amendments to the Basin Plan, or deleted altogether as |l indicated by Table 6-2. However, some markets for reclaimed water are located in areas of Carlsbad where the numerical objectives are less than 2,500 mg/l TDS. Those areas ft will either need to be relaxed with additional Basin Plan amendments, will have to use fi only costly demineralized reclaimed water for irrigation, or will be excluded from reclaimed water use. IP h Waste Discharge Requirements are prepared by the San Diego RWQCB on a case-by- case basis. Salt and water mass balances submitted in the Report of Waste Discharge R will be important in establishment of the ultimate reclaimed water quality requirements. * Such parameters as site-specific soil characteristics, crops being grown, irrigation practices, and groundwater quality will be important in preparing the Report of Waste Ij Discharge to meet the Basin Plan requirements. An analysis may require a detailed salt balance study or, in the case of a proposed relaxation of the Basin Plan, a detailed pi hydrogeologic investigation, particularly if there are significant beneficial uses of the m groundwater.

The 1972 ™ amendments to the Federal Water Pollution Control Act (Clean Water Act), prohibit the _ discharge of any pollutant to the navigable waters from a point source unless the L discharge is authorized by a NPDES permit. Any surface application or discharge of reclaimed wastewater constitutes a point source, and requires a NPDES permit. The p RWQCB establishes effluent discharge and receiving water monitoring and reporting H programs to ensure compliance with the discharge requirements. • 6.3 LOCAL INSTITUTIONS AND REQUIREMENTS Management and water quality in the study area entails close coordination among the E institutions concerned with planning and maintaining environmental quality. The composition, jurisdiction and functions of wastewater management and planning agencies involved in the implementation of the proposed water reclamation project are P discussed in the following paragraphs.m 6.3.1 California Coastal Commission and Local Coastal Program ^^ ^With the passage of Proposition 20, the California Coastal Zone Conservation Act of pi 1972, a State Coastal Zone Conservation Commission, and six Regional Commissions L were created. This 1972 Act was subsequently superceded by the 1977 California Coastal Act which spelled out in more detail the policies regarding protection of the •m resources on the Coastal Zone. The 1977 Act also initiated the Local Coastal Plan *, process for local jurisdictions to eventually take over the issuance of the Coastal Development Permits. The coastal zone extends from Oregon to the Mexican border. "* The zone includes the land and water area seaward to the outer limit of state jurisdiction, b including all islands within that jurisdiction. The zone extends landward to the highest elevation of the nearest coastal mountain range. m Within the coastal zone, a permit area extends from the seaward limits of state ^ jurisdiction to 1,000 yards landward from the mean high tide line, subject to specified exceptions. Any development within this permit area is prohibited without a Coastal *" Development Permit. The Act establishes criteria and requires submission of plans for p. the preservation and enhancement of the environment and the ecology of the coastal zones of California. It also prescribes standards for the issuance or denial of these special permits. With the completion of the San Dieguito Land Use Plan by the County of m San Diego, and the adoption of implementing ordinances for the Local Coastal Program, H the County will soon be the responsible Agency for the Coastal Development Permits. The western portion of the study area is within the boundaries of the coastal zone and *" therefore in the jurisdiction of the Coastal Commission as shown in Figure 2-2. MM The Coastal Commission does not have policies specifically regarding reclaimed water, "" but if the project requires development of presently undeveloped land within the coastal 6-12 ** zone, a coastal development permit would be required. For development such as installation of a pipeline, a coastal development permit would probably not be required if it were installed in easements or right-of-ways which presently contain utilities. p 6.3.2 San Diego County Hi The County of San Diego office of Special Projects has sponsored the preparation of S studies which included the Carlsbad area. The San Diego Water Reuse Study, Volume V Encina Basin Feasibility Study, completed in February, 1988, identified the potential water reuse markets in the Encina Basin, and investigated the feasibility of new m reclamation facilities within the basin. m The San Diego County Department of Health Services, along with other state and local P agencies, reviews the Report of Waste Discharge for the RWQCB. They are also to responsible for mosquito abatement in water impoundments, which includes any open storage reservoirs used for reclaimed water. The mosquito abatement methods include: ^^ • • Impoundments can be lined or sufficiently sloped to discourage rooted aquatic plant growth along pond edges which provide protection for mosquito larvae, • Drainage water and impounded water can be circulated and kept moving to m minimize mosquito breeding, and m • Impoundments can be sprayed with a thin layer of an oil-like substance to suffocate «"» mosquito larvae. *» Any planned improvements for reclaimed water should receive review by the mosquito *" abatement group of the County Department of Health Services for vector control «•> guidance. *~ 6.3.3 San Diego County Water Authority ^ The San Diego County Water Authority (CWA) formed the Water Authority Reclamation Advisory Committee (WARAC) in November, 1987. It is made up of all public water *" purveyors and sewer agencies in San Diego County, and will study and evaluate •. proposed water reclamation projects, and make policy recommendations to the Board of m the SDCWA. *» 6.3.4 San Diego Association of Governments m The San Diego Association of Government (SANDAG) was formerly called the "* Comprehensive Planning Organization (CPO). SANDAG is the Clearinghouse Agency *• for all projects requesting State or Federal grant funds within its jurisdiction which includes the County of San Diego and sixteen member cities within the County. *"" SANDAG operates under a Board of Directors appointed by each of its member 6-13 m If agencies. SAN DAG develops land use planning and population projection models to aid in efficiently planning development and the corresponding need for service in San Diego * County, and reviews projects to ensure that proposed facilities are rationally planned. * Other functions include transportation planning and crime information data management.m.m E 6.3.5 Association of Water Reclamation Agencies In northern San Diego County, many of the cities, water districts, and sanitation districts have joined to form the Association of Water Reclamation Agencies (AWRA). The goals of AWRA, which was formed in 1980, are to promote and encourage the beneficial uses of reclaimed water. Members of AWRA include the Cities of Carlsbad, Oceanside, and Vista; Carlsbad Municipal Water District (CMWD); San Dieguito Water District (SDWD); Vallecitos Water District (VWD); and Vista Irrigation District. The objectives of goals AWRA are to: • Provide a forum to discuss and coordinate water reclamation projects, • Promote development of reclaimed water to meet the goals and expectations of the area's water users, • Develop a project assistance and/or advisory committee, • Facilitate interagency and intergovernmental cooperation at all levels, • Maintain a library for project reports, sample agreements, contracts, technical specification, rules and regulations applicable to water reclamation, and • Maintain a list of agencies providing water reclamation grants. 6.4 RECLAIMED WATER QUALITY CRITERIA AND TREATMENT REQUIREMENTS The level of wastewater treatment and resultant water quality required for each potential class of reuse must be identified to screen potential users and further develop alternative treatment and disposal schemes. Three general reuse options are available, irrigation uses, industrial uses, and ecological uses, with varying water quality criteria. Criteria for landscape irrigation is discussed in the following sections with regard to user requirements. 6.4.1 Reclaimed Water Quality Criteria 6.4.1.1 Landscape Irrigation Water Quality Criteria In determining the acceptability of a water for irrigation purposes, the effect of specific ions on plant growth as well as the physical and chemical factors in the relationship 6-14 m between ionic concentrations, soil and plant metabolism must be considered. The „„ specific factors are important in this analysis: m • Soil salinity hazard, determined on the basis of total dissolved solids or electrical m conductivity, • Soil permeability hazard, as related to total salt concentration and concentration of p sodium relative to calcium and magnesium, m • Specific ion toxicities caused by sodium, chloride, boron, or nitrogen, andm if • Other criteria including impact of heavy metals and potential for clogging irrigation piping systems. p ^ A discussion concerning reclamation of wastewater for landscape irrigation must include a comparison of the quality of reclaimed water with standards applicable to irrigation R use. From past studies by agricultural experts, standards for irrigation water classification have been adopted by the U.S. Department of Agriculture, the Cooperative p Extension Service, and others. Guidelines developed by the University of California |i Cooperative Extension Committee of Consultants are presented in Table 6-4. ~ 6.4.1.1.1 Salinity m Salinity is one of the most important water quality parameters for landscape irrigation *» water quality considerations. Changes in salinity result in changes in osmotic pressure •. of the soil solution in the root zone, which affects the availability of water for plant consumption. Salinity is measured by determining the electrical conductivity (EC) of a ** solution, which is a measure of the ability of salts in solution to conduct electricity, and is »» expressed as micromhos per centimeter (/imho/cm) at 25 °C. While carbonates of ^ calcium and magnesium may precipitate in harmless form in the soil, and other salts may *"* precipitate as calcium sulfate or may not reach a damaging concentration, the EC of an "* irrigation water does give a parameter which can be correlated with plant growth. When waters with salts in excess of plant tolerance levels are used for irrigation, soil salinity may be controlled by leaching. Leaching is the introduction of excess water »- beyond evapotranspiration levels into the root zone to carry salts below the root zone to before toxic concentrations accumulates. If soil salinity is a problem, permeability rates must be adequate for the penetration of water in sufficient quantity for both ** evapotranspiration and leaching. A leaching fraction, or excess water application, of 15 ta> to 20 percent was assumed as a basis for deriving the guidelines prescribed in Table 6- 4. By increasing the leaching fraction to 30 percent, the impact of saline irrigation water *" on plants could be minimized, but prolonged irrigation could also damage plants from *"• water logging and poor aeration. 6-15 Table 6-4 ,„ Standards for Irrigation Water "• Water Quality Guidelines *" Severe *t Factor No Problem Problem Problem pi IH Salinity, EC in/imho/cm <750 750-3000 >3000 Permeability, percent sodium <60 60-75 >75 _ Specific ion toxicity from root absorption L Chloride, mg/l <142 142-355 >355 •• Boron, mg/l <0.5 0.5-2.0 2.0-0.0 From foilar absorption P Sodium, mg/l <69 >69 Ml Chloride, mg/l <106 >106 Miscellaneous Constituents p NH,, mg/l for sensitive crops <5 5-30 >30 Ig HC03, mg/l <90 90-520 >520 pH Normal Range 6.5-8.4 Source: University of California Cooperative Extension, 1975. Table 6-5 presents the tolerance of major San Diego agricultural crops to salinity as IDS as well as boron and chloride. Ornamental plants and ground covers vary in their tolerance to salinity. Most common species and grasses are tolerant of medium salinity levels, which allows full use of reclaimed water on golf courses, parks, and other landscaped areas. Ornamental shrubs and covers which are intolerant of high salinity levels include star jasmine, pineapple, guava, burford holly, rose, algerian ivy, hibiscus and heavenly bamboo. 6.4.1.1.2 Permeability Permeability is related to the organic and clay fractions of the soil, which carry predominantly negative charges, and the varying amounts of positive ions, or cations, in the soil. The distribution of adsorbed cations in the soil is in equilibrium with the soil solution; irrigation or fertilization disturbs the equilibrium and alters the distribution of adsorbed ions in the soil. When calcium is the predominant cation adsorbed on this exchange complex, the soil develops a granular structure which is easily worked and permeable. When the amount of adsorbed sodium exceeds 10 to 15 percent of the total cations on the exchange complex, the clay becomes less permeable, unless a flocculated condition is maintained due to a high concentration of total salts. 6-16 mi Adsorption of sodium from an irrigation water is a function of the proportion of sodium to the divalent cations, calcium and magnesium, in the water. An estimate of the degree to which sodium will be absorbed by a soil from a given water is the sodium ratio. The sodium ratio or percent sodium is expressed as the following: Percent sodium = [Na]/([Na] + [Ca] + [Mg]) where concentrations of the cations are in milliequivalents per liter.

Sodium, chloride, boron, and nitrogen, in high concentrations, are of particular concern in landscape irrigation because of their ^ potentially toxic effects on some plants. Tree crops and woody perennials are especially susceptible to sodium and chloride, and annuals also are affected at higher m concentrations of these ions. Sprinkler irrigation can lead to special problems due to H foliar absorption of sodium and chloride. P Chlorides in irrigation water are considered to be among the most troublesome of li anions. Plants grown on some soils show their injury by subnormal growth rates. Symptoms of chloride injury are a yellowing of leaves, followed by a burning around their •* margins and excessive exfoliation. 6-17 ib Boron, in low concentrations, is an element necessary for plant growth; however, at f* concentrations greater than 0.5 mg/l, boron can be increasingly toxic to plant life. Boron h* absorbed by the roots from the soil solution is moved to the leaves, where the water is lost by transpiration. Boron remains in the leaf and tends to accumulate in the tip and f* margin. As the process continues, the boron concentration becomes toxic to the leaf ^ tissue. Among trees advanced damage will result in leaf-yellowing and burning, premature leaf drop and reduced yield. The quality of soil, drainage, and climatic and E other environmental factors, such as the amount of rainfall and total amount of irrigation water applied, can modify the safe concentration limits. The symptoms of boron injury m may not become apparent for several years; the effect is cumulative and only mature ^ plants show signs of boron toxicity. Crop tolerances for both boron and chloride are presented in Table 6-5. I The forms of nitrogen found in wastewater, largely ammonium with some nitrate, behave in the same manner as applied fertilizer nitrogen. Nitrogen is an essential component of JP proteins and other constituents of living matter and is generally available to plants as II nitrate ion. When nitrogen is applied to soil in the ammonium and nitrite forms, nitrifying bacteria in the soil convert it to available nitrate ion. Organic forms of nitrogen undergo ** biodegradation with conversion of the nutrient elements to simple inorganic forms which ^ plants can assimilate. Excessive nitrogen levels may cause problems in some sensitive plants by stimulating vegetative growth instead of flowering and fruiting. IF* ta 6.4.1.1.4 Other Criteria r*L Some trace elements are essential for plant growth and negatively affect plants only when plant tolerance levels are exceeded. When an element is added to the soil by «• irrigation in toxic amounts, it may combine in the soil to decrease the concentration to ^ below toxic levels, or it may increase the accumulation of that element in the soil. If the process of adding irrigation water containing a toxic level of the element continues, a •• steady state will be approached with time in which the amount of the element leaving the H soil in the drainage water will equal the amount added with the irrigation water, and no further change in concentration in the soil will occur. Some elements may be toxic in relatively low concentrations. Irrigation water containing trace toxic levels of elements may be added for many years before steady state is approached and a situation exists where toxicities can develop years later from the continued addition of trace elements in irrigation waters. Guidelines for safe levels of some trace elements in irrigation water are presented in Table 6-6. 6-18 Table 6-6 Guidelines for Trace Elements in Irrigation Water Recommended Maximum Concentration, mg/l Continuous Use Up to 20 Years Use on Fine Element on All Soils Textured Soils of pH 6.0 to 8.5 Aluminum Arsenic Beryllium Boron Cadmium Chromium Cobalt Copper Fluoride Iron Lead Lithium Manganese Molybdenum Nickel Selenium Vanadium Zinc Source: Environmental 1972. 5.0 0.1 0.1 0.01 0.1 0.05 0.2 1.0 5.0 5.0 2.5 0.2 0.01 0.2 0.02 0.1 2.0 Studies Board, National Academy of Science, 20.0 2.0 0.5 2.0 0.05 1.0 5.0 5.0 15.0 20.0 10.0 2.5 10.0 0.05 2.0 0.02 1.0 10.0 National Academy of Engineering, Water Quality Criteria, High concentrations of suspended solids in irrigation water can affect surface irrigation interfering with the flow of water in conveyance systems and structures. Deposits of sediment reduce the capacity of these systems to carry and distribute water and can also decrease reservoir storage capacity. In sprinkler irrigation, suspended mineral solids may cause additional wear or plugging of irrigation pumps and sprinkler nozzles, and reduce irrigation efficiency. Soils are affected by deposition of these suspended solids, especially when they consist primarily of clays or colloidal material, which cause crust formations and reduce seedling emergence. These crusts also reduce infiltration and reducing irrigation efficiency and hinder the leaching of saline soils. Suspended solids high in silt may improve the texture, consistency and water-holding capacity of a sandy soil. 6-19 if Reuse of water from wastewater generally allows for a greater possibility of direct human contact with effluents. The proper treatment and safe application of reclaimedm wastewater are essential to the protection of public health. The potential hazard to ** public health is judged by the number of coliform group organisms present in the water, usually expressed as the most probably number (MPN) per 100 milliliters. While ^ organisms of this group are generally not pathogenic or disease producing, they are * present in immense numbers in the fecal discharges of all warm-blooded animals, and p are a useful indicator of the potential presence of pathogenic bacteria of wastewater L origin. Different end uses of reclaimed water dictate different limiting amounts of coliform, as presented previously in Table 6-1. Jg 6.4.1.2 Industrial Water Quality Criteria f Like irrigation uses, industrial uses may be sensitive to the quality of reclaimed water. w The quality of water required for industrial applications is dependent on the type of application. Some industrial uses, such as gravel washing, may be relatively unaffected f* by the reclaimed water quality. Other uses may require a reclaimed water supply that is A* free from organics or minerals (e.g. cooling water and boiler make-up water). Use- related water quality requirements for individual industries should be assessed on an ** individual basis to determine whether the use of reclaimed water is acceptable.h. _ 6.4.1.3 Ecological Enhancement Water Quality Criteria ^ Use of reclaimed water for ecological enhancement of streams, lakes and other «. recreational areas is sensitive to the quantity of flow and the nutrient content of the reclaimed water. Lacustrine and coastal wetland environments can be expected to be sensitive to the changes in stream flow and water quality, particularly with regard to the P» addition of nutrients from reclaimed water discharges. M 6.4.2 Reclaimed Water Quality Treatment Requirements m HI As presented in the previous paragraphs, reclaimed water requires further treatment beyond secondary treatment for unrestricted Title 22 use. The tertiary treatment 2 processes that are required are coagulation and flocculation, filtration, and chlorination. 6.4.2.1 Coagulation and Flocculation j^I Coagulation and filtration are pretreatment processes following secondary treatment and p proceeding filtration which enhance the removal of particulate matter in the filtration m process. The coagulant used is a polymer, or a polymer in conjunction with alum. Polymers or polyelectrolytes are high molecular weight compounds which act as bridges P» in reducing charges between colloidal and dispersed floe particles, which increases m settling velocities. Polymers are available in either bulk, dry or liquid form. In the dry form, wetting, mixing and aging equipment is required, and in the liquid form, tanksm constructed of fiberglass reinforced plastic or other corrosion resistant material is m r 6-20 p In required. Alum is a coagulant which reacts with the alkalinity and phosphate in wastewater to form insoluble aluminum salts. Like polymers, alum can be supplied in ** either dry or liquid form, and requires similar handling and storage equipment. Rapid mixing is necessary to assure that the coagulants are effectively dispersed in the r wastewater prior to flocculation. The flocculation process involves the use of a basin and ** mechanical mixers for the agglomeration of floes of colloidal material when the p coagulants are added. Flocculation requires low energy mixing so that colloidal floes are L not sheared and sufficient contact time for floe formation. p 6.4.2.2 Filtration There are two configurations of tertiary wastewater filters that conform to Title 22 and pu that have been approved by the DHS. These filters are the conventional gravity or |y pressure filters that require separate cycles for filtration and media backwashing, and the continuous operation filters in which the media is continuously backwashed. Continuous P backwash filters have the advantage that backwash surge tanks and high flowrate M backwashing equipment is not required. Also the backwater stream produced is a steady flow that reduces hydraulic shock loading to the treatment facilities. *• 6.4.2.3 Chlorination Chlorination is the typical method of disinfection of reclaimed water. When chlorine gas ** is used the process begins with the dissolving of chlorine gas in water to form m hypochlorous acid and hypochlorite ions. These compounds react immediately with ^ ammonia nitrogen in the wastewater to form chloramines, which with hypochlorites, provide the disinfecting power. The process of chlorine disinfection is the combined *• effect of chlorine dosage rate, mixing and contact time with the wastewater. Urn To meet the requirements for disinfection for unrestricted Title 22 use, the chlorine "" contact chamber must have a theoretical chlorine contact time of two hours and an ** actual contact time of at least 90 minutes at maximum design flow. The contact basin must have a length to width ratio of about 40 to 1 to insure plug flow and to prevent short *"* circuiting. In addition to the chlorine gas injection and metering equipment, automatic ** chlorine residual monitoring would be required. •» m m m m 6-21 CHAPTER 7 RECLAIMED WATER MARKETS 7.1 DEFINITION OF MARKET AREA jy The scope of the reclaimed water market area for this project is the City of Carlsbad, and markets are identified in the service areas of the CMWD, VWD and the OMWD. The m existing potential markets lie in the developed areas of the City as well as agricultural m areas both north and south of Palomar Airport Road. Also, the rapidly expanding industrial parks adjacent Palomar Airport Road are additional potential markets. Future m potential markets are found primarily in the eastern portion of the City. The City of • Carlsbad General Plan allows further planned industrial and residential development north of the Batiquitas Lagoon, southeast of Agua Hedionda Lagoon and east of El "" Camino Real. ^ 7.2 IDENTIFICATION OF MARKET TYPES *"" For the purposes of this study, the term "reclaimed water market" was used to identify a P. location where reclaimed water could be used to replace the use or future use of ^ municipal (potable) water. Reclaimed water can also be used to replace the use of groundwater or improve the quality of the groundwater that is being used, especially for — irrigation purposes. Enhancement of riparian habitats is also a productive use of to reclaimed water according to the RWQCB. These uses were considered potential "reclaimed water markets" in this study. Reclaimed water markets can be divided into *" three main categories: irrigation uses, industrial/commercial uses, and ecological uses. m The following discussion will highlight the potential uses for reclaimed water within the City of Carlsbad. Specific markets are shown on Figure 7-1 . Table 7-1 summarizes the *" specific potential reclaimed water uses in the City of Carlsbad.«• m 7.2.1 Irrigation Uses ** Irrigation uses of reclaimed water include the irrigation of pastures, crops, nurseries, golf ,M courses, cemeteries parks, campuses, and residential, commercial and freeway 1^ landscaping. Both public and private facilities are included in this study as potential reclaimed water markets. For irrigation in this area, reclaimed water provides a more *• reliable and potentially less expensive source of water than is currently available. «• 7.2.1.1 AgriculturaMrrigation m As in the rest of San Diego County, agricultural operations in the City of Carlsbad have given way to urbanization. Agricultural irrigation requirements, therefore, have been f* reduced to a small fraction of what was previously a large water demand. Agricultural 7-1 use of reclaimed water, however, should not be dismissed. The CWA cites the following reasons: that the availability of reclaimed water may encourage and enable remaining agricultural users to stay in business or to expand their operations; that reclaimed water may in the future be the only water available to growers; that inclusion of an agricultural operation as a reclaimed water market in an overall water reclamation project may enhance the feasibility of that project; and finally, that the conversion of agricultural land to urban use may result in an equal reclaimed water demand for landscape irrigation. 7.2.1.2 Golf Course Irrigation Golf courses provide a practical market for reclaimed water due to their large irrigation demands. Reclaimed water is typically used to irrigate golf course fairways and roughs. Greens and tees are sometimes maintained with potable water because of the sensitivity of the grasses and the desire to keep these areas in top condition. Golf course superintendents are concerned with the quality of the reclaimed water, its impact on golf course turf, and the cost of reclaimed water. The Golf Course Water Conservation Group was recently formed in San Diego County to address the issue of water conservation at golf courses in a potential drought situation. The group consists of golf course managers, developers, irrigation system manufacturers and vendors, and others involved in the local golf course industry. The group intends to be involved with the development of reclaimed water as a resource and to represent the needs of the golf course industry. 7.2.1.3 Freeway and Median Landscape Irrigation Water use by the California Department of Transportation (CALTRANS) for irrigation of landscape along freeways within San Diego County offers another potential market for reclaimed water. Areas of landscaping along freeways include medians, rights-of-way, and interchanges. Interstate 5 traverses north-south along the west side of the market area, and presents an opportunity for reclaimed water use. Landscape within medians maintained by the City are also candidates for reclaimed water use. 7.2.1.4 Parks, School Turf, and Landscaped Area Irrigation One of the largest potential uses of reclaimed water in San Diego County is the irrigation of various city, county, and state parks. No county parks are located in the market area; however there are two state parks and several city parks within the study area. In addition to the city parks, the City also maintains school turf and several landscaped areas. 7.2.1.5 Residential and Commercial/Industrial Development Landscape Irrigation Landscape irrigation within residential and commercial/industrial developments is a potential market for reclaimed water in the developing areas of the City. Reclaimed water 7-2 M can be used to irrigate common areas in residential neighborhoods. Another beneficial use of reclaimed water would be to irrigate fire breaks behind developments that border IP canyons, because brush-laden slopes present a major fire hazard. By landscaping a it 200-foot wide strip at the top of the slopes with a fire retardant plant and requiring regular irrigation with reclaimed water, a firebreak could be maintained. The cost of this f irrigation should be compared to the potential loss of life and property, as evidenced by i» the devastating Normal Heights fire in 1985. * The best opportunity for this type of market are those developments in the planning or ** conceptual stages. Reclaimed water facilities can be readily incorporated into these m future developments. Existing developments that have separate irrigation meters are I also potential markets since minimal onsite retrofitting would be required to serve those developments. «• ^ 7.2.2 Industrial/Commercial Uses IP Industrial use of reclaimed water remains an undeveloped market in San Diego County. iy However, this market provides a use for reclaimed water that usually does not vary seasonally and therefore is a good candidate for reclaimed water use. Typical uses for f" industrial purposes within the market area include boiler water, cooling tower makeup ** water, air conditioning uses, and process water. *" The General Plan designates a moderate amount of area for industrial/commercial ** development along the Palomar Airport Road corridor. It is expected that the majority of m these activities will be the type conducted by relatively "dry" industries which would not require large amounts of water as is the case of those already existing in the industrial ** parks. However, industrial operations using major quantities of water include Hughes P. Aircraft, SDG&E's Encina Power Plant, and the Encina WPCF. m Relatively new potential markets for reclaimed water are the numerous existing or *» proposed commercial buildings within the market area. These buildings, if dualed to plumbed for use of a gray-water system, could utilize reclaimed water. It has been estimated by the Irvine Ranch Water District (IRWD) that the toilets and urinals in a *" commercial building account for approximately 60 to 80 percent of the building's total to daily water consumption. If gray-water systems were utilized, the reclaimed water for plumbing could be dyed to distinguish it from potable water. ^^^ "* 7.2.3 Ecological Uses 7.2.3.1 Lagoon/Stream Enhancement «. The streams and lagoons in the market area support lacustrine, riparian, and estuarine to environments. Concerns with regard to enhancement with reclaimed water vary for each habitat. Reduced water movement in the ponded areas or lacustrine environment •» contributes to extended water detention times, vertical stratification, and potential for 7-3 substantial nutrient cycling. In a riparian environment algal growth can be continuously exported from the system, however in a lacustrine environment, algae may settle out and become incorporated into the bottom sediments, providing an auxiliary source of nutrients for algal growth in subsequent years. Provided, however, that there is adequate nutrient removal and significant flow volume, the San Diego RWQCB believes that reclaimed water discharges can be expected to have a positive effect on most lacustrine environments. Similarly, estuarine habitats are also sensitive to nutrient loadings. Another concern is the effect on the saline conditions in this habitat if a uniform, continuous freshwater flow is discharged through the estuary. The San Diego RWQCB maintains that through effective management of the volume, timing and location of the increased dry-season stream flows, a coastal wetland can benefit from improved water circulation, an increased frequency and extent of tidal exchange, a reduction of hypersaline conditions, and the creation of true estuarine conditions. Small stream flows could be utilized to enhance both the germination and growth of particular marsh vegetation, however large flows may have to be diverted. 7.2.3.2 Groundwater Recharge Groundwater recharge is accomplished when reclaimed water is purified and stabilized as it percolates vertically through the zone of aeration and moves laterally in an aquifer. The percolated reclaimed water enters and is stored in aquifers from which it can be withdrawn by wells and used for beneficial purposes. Effective groundwater recharge requires an extensive aquifer with suitable geologic structure. If a suitable aquifer were available in the area, recharged groundwater could be used for irrigation and the aquifer could be used for wet-season storage of reclaimed water which would be of better quality than the local groundwater in the basin. 7.3 MARKET RESEARCH Information on potential reclaimed water markets was obtained through a variety of resources. Reports on water reclamation in the study area, such as Lake Calavera Hills Reclamation System Update Report submitted to the City of Carlsbad by Glenn M. Reitter & Associates and Lowry & Associates, Wastewater Reclamation Master Plan Study and Overview of Wastewater Reclamation Opportunities prepared by Lowry & Associates for the City of Carlsbad, Luke-Dudek's Aviara Reclaimed Water Facilities Plan, and the reports on water reclamation within the Encina Basin by John S.

The City also provided a list of customersm who have separate irrigation or agricultural meters. The Carlsbad Tract Log was m reviewed as were the Planning Department files for specific information such as total acreage, status, name of developer, location, type of development, and landscape ^ plans. Information on the planned industrial areas was obtained from the Zone 5 Local Facilities Management Plan and the Zone 16 Acreage Summary. The City of Carlsbad p General Plan and Zoning Map were used extensively for determining future reclaimed In water markets. m A list of potential reclaimed water users was prepared from the above sources. An || attempt was made to contact each potential user by telephone. Information compiled from telephone calls and site visits includes the following: the type of use, whether that «* use is seasonal or uniform, the quantity of water used annually and seasonally, the m quality of water required for that use, the pressure requirements to serve that market, the owner's interest in use of reclaimed water, the current cost to provide water to that m market, and the future plans for water use at that location. Hi m 7.4 DESCRIPTION OF SPECIFIC MARKETS *" The locations of specific potential markets in the City of Carlsbad are shown in Figure 7- *. 1. The markets have been grouped into several categories: agricultural, golf courses, to freeway, parks, schools, landscaped areas, medians, residential, commercial/planned industrial, industrial use, and commercial use. The irrigational markets have been — subdivided into several groups. The specific markets in each category are discussed h, below. The potential markets in shown on Figure 7-1 are numbered approximately from northwest to southeast. *• Table 7-2 summarizes the demands of potential reclaimed water markets. The number of total acres and irrigated acres is noted, if known and applicable. The use factor, or *" application rate in Table 7-2 applies only to irrigated areas and refers to the number of *• acre-feet per acre per year (AF/AC/YR) that is used at that location. The criteria used to ^ develop the use factor are described in detail in sections that follow. Table 7-2 lists the annual water use in acre-feet (AF) and the peak daily water use in gallons per day (gpd). ** The annual water use is totaled at the bottom of Table 7-1. Peak daily reclaimed water — use in 1995 is estimated to be approximately 11.69 mgd with an average annual use of m 5.63 AF/YR and increasing to approximately 21.35 mgd peak daily use and 10.39 AF/YR annual use in 2013. to An expanded version of Table 7-2 is included as Appendix E. Appendix E shows the estimated demand at five year intervals from the year 1990 to the year 2015. Many "" markets do not change throughout this time period. For each market, the type of use *• (seasonal or uniform) is noted. Seasonal use refers to irrigation use, which varies seasonally. Uniform use refers typically to an industrial use that does not vary ** seasonally. Appendix E also lists the status of the market. The status is either existing, 7-11 proposed, or in the case of future residential and commercial/industrial developments that are filed with the City, the status may be tentative maps approved, final maps approved, or being processed. Markets projected to undergo either increases or decreases in water use are the result of land use changes. For large new developments, phased buildout and therefore phased reclaimed water use was assumed for water use projections as described in Section 7.4.1.8 Residential and Commercial/Industrial Development Landscape Irrigation. Because reclaimed water is not used uniformly throughout the year, low, average and peak daily flows were estimated for irrigation markets and shown in Appendix E. The criteria used to estimate peak and low use factors is developed in Section 7.4.1.1.1 Seasonal Demands. Low daily water use is assumed to occur in the winter months of January or February, when irrigation needs are small. Peak daily water use is assumed to occur in the summer months when irrigated demands are high. 7.4.1 Irrigation Water Demands The variations in irrigation water demand, both seasonal and application rate, and the specific irrigation demand markets including agricultural, golf course, freeway and median, park and school turf, residential, commercial, and industrial uses, are discussed in this section. 7.4.1.1 Variations in Irrigation Demands 7.4.1.1.1 Seasonal Demands Irrigation water demands are non-uniform, varying seasonally from the effects of wet and dry weather periods. The seasonal nature of crops also effects the water demands of agricultural irrigation. Peak applications are applied during the dry summer months, and low applications occur during the wet winter months. Individual irrigation user water consumption data and recent seasonal irrigation water use estimates developed by the CWA were used to develop a composite seasonal water demand curve. Comparisons with previous seasonal demand curves used in past water reclamation studies for several San Diego County communities were also made. Table 7-2 presents the seasonal demand data used in this report, in which the demand in August is 2.16 times the average month demand. 7-12 m Table 7-2 ^ Seasonal Variation in Irrigation Demand Values ft* Ratio of Peak Monthly *" Percent of Use Rate to Average to Month Total Annual Demand Monthly Use Rate January February March April May June July August September October November December 2.5 3.0 4.5 5.5 7.0 10.0 17.5 18.0 12.5 9.0 6.0 4.5 0.30 0.35 0.54 0.66 0.84 1.20 2.10 2.16 1.50 1.08 0.72 . 0.54 The precise annual irrigation demand pattern will vary slightly from location to location depending on climate, soil conditions, method of application, type of crop, etc. The changes due to seasonal demand, however, will generally follow the pattern shown in Table 7-2. 7.4.1.1.2 Irrigation Application Rates The amount of water required for irrigation is dependent on the type of vegetation, soil type and condition, hours of daylight, temperature, topographic and geologic conditions, and the method of irrigation water application. The net irrigation water required over a specified period of time defined as the depth of water needed to meet the water loss through evapotranspiration, leaching, seed germination, climate control, frost protection, and fertilizer application. In San Diego County, rainfall provides only a fraction of the net irrigation water requirement for most plants. Irrigation systems are designed to apply enough water to supplement the amount of water provided by rainfall, and satisfy the net irrigation requirement. Methods for determining irrigation application rates are based on the reference evapotranspiration rate, the rate of precipitation, and efficiency factors associated with the application method, and the type of crop and crop coefficients. Evapotranspiration rates are dependent on the type of vegetation and climate. Precipitation rates in the study area of this report average 12 inches per year near the coast, and 14 inches per year inland. Application efficiencies for irrigation distribution systems typically range from 70 to 80 percent. 7-13 The CWA estimates the total water requirement for vegetation in coastal San Diego *" County to range from 30 to 45 inches per year. Of this amount approximately 12 inches *" is provided by rainfall. Therefore, irrigation must provide 18 to 33 inches of water to ^ meet this requirement. M For this report, an average applied water irrigation demand of 30 inches per year was ,_ used for landscape irrigation markets unless more specific data was available from the ^ user. The applied water irrigation rates for each type of irrigational use is presented in the description of the specific markets. i* m 7.4.1.2 Agricultural Irrigation ** Agricultural operations in the City of Carlsbad are limited. About 1,100 acres supporting it agricultural operations were identified as potential reclaimed water markets. The markets identified included about 560 acres of flower fields; 440 acres of tomatoes, squash, ^* cucumbers, and beans; and 90 acres of strawberries. The Plan and Zoning Map h* indicates less then 500 acres will remain in the agricultural zone/non-residential reserve. The Tabato Brothers Farm, Ukegawa Farm, and a portion of Frazee Flowers are located *~ in this area and will likely continue their agricultural operations with the exception of the * Tabato Brothers Farm. Mr. Iso Tabato stated that he will discontinue his operations ^ within three years and Frazee Farms will probably expand their flower fields onto the ta property. P- Discussions with the major growers indicated an irrigation rate or use factor of 3 ito AF/AC/YR for strawberries; 2 AF/AC/YR for beans, squash, and tomatoes; and 1.5 AF/AC/YR for flowers. These rates are relatively low in comparison to data published by *• the Department of Agriculture and rates presented in the Costa Real Municipal Water m District Master Plan for Public Water System by Woodside/Kubota and Associates, Inc. in February 1985 which were established by researching water meter records. Irrigation ** rates from these sources range from 2 to 6 AF/AC/YR for strawberries, 2 to 3 *• AF/AC/YR for vegetables, and 3.5 to 4.2 AF/AC/YR for flowers. For this report, the irrigation rates indicated by the major growers were used to compute the potential reclaimed water demands for all the agricultural markets based on the specific crop m grown. The estimated peak daily reclaimed water demands for agricultural irrigation are PB, 2.66 mgd in 1995 and 0.78 mgd in 2015. *7.4.1.3 Golf Course Irrigation •• m The existng golf courses in the City of Carlsbad are the Rancho Carlsbad Golf Course located on El Camino Real in the northeast part of the City and the La Costa Golf f1 Courses in the southeast portion of the City. Approximately 84 acres are irrigated at the M Rancho Carlsbad Golf Course. Mr. Paul Grahm, Vice President of the La Costa Hotel and Spa, specified that 310 acres are irrigated. There are also three proposed golf m courses that are potential reclaimed water markets. These are the Lake Calavera 7-14 ** Municipal Golf Course, the McClellan Executive Golf Course, and the Aviara Golf Course. Mr. Mark Steyaert of the Parks and Recreation Department estimated 150 acres of the f* 250-acre Lake Calavera Golf Course would be irrigated. A 180-acre golf course is *" planned as part of the Aviara development and the water demands for this golf course _ are included in those presented for the Aviara development listed as residential.j^ JL Irrigation rates used to estimate the water demand for golf courses in previous reports p, varies from 2.0 AF/AC/YR to 3.5 AF/AC/YR. For this report, 3.2 AF/AC/YR was used to ty estimate the water demands for both existing and proposed golf courses with the exception of the Aviara golf course. The peak daily reclaimed water demands for the golf p courses are 3.60 mgd in 1995 and in 2015, excluding the Aviara Golf Course. M ' 7.4.1.4 Freeway and Median Irrigation m It Discussions with Mr. Tom Ham of CALTRANS indicated that CALTRANS is very interested in using reclaimed water along the State freeways. Currently, within the City of ** Carlsbad, the median of Interstate 5, three interchanges, and portion of the right-of-way ^ are fully landscaped, irrigated, and maintained by CALTRANS. According to Mr. Ham, the median landscaping will be removed and irrigation discontinued within five years; , however, new landscaping is planned for the right-of-way and the other interchanges. Reclaimed water use can be incorporated as these changes take place. For the type of P, interchanges along Interstate 5 within the City of Carlsbad, there would be approximately , 4 to 10 acres of landscaping, depending on the configuration. The interchanges will be fully landscaped, requiring 2 AF/AC/YR. The right-of-way landscaping would average *» about 70 feet on both sides of the freeway. Based on data provided by CALTRANS, each ^ mile of freeway would be equivalent to 8.3 acres. The type of landscaping planned for the right-of-ways would require 1 AF/AC/YR. The total landscaping along Interstate 5 *" within the study area would cover about 90 acres. The estimated peak daily irrigation ». demands for freeways are 0.35 mgd in 1995 and in 2010. *" The City of Carlsbad irrigates and maintains several landscaped medians in roads ** throughout the City such as El Camino Real, College Boulevard, Palomar Airport Road, and Rancho Santa Fe. Although these areas are small, they can be easily irrigated with reclaimed water if they are located adjacent a distribution line or larger market. to According to the data provided by the City of Carlsbad, these landscaped areas receive „« 1.88 AF/AC/YR of irrigation. The individual medians are listed in Table 7-1, but they were ^ not assigned a number as they are not shown on Figure 7-1. The estimated peak daily irrigation demands for City maintained medians are 0.02 mgd in 1995 and 2015. m 7.4.1.5 Park Irrigation "* The City parks are predominately located in the northwest part of the City with the li exception of the La Costa Canyon and Stagecoach Parks which are located in the southeastern portion of the City within the La Costa development, and the Calavera Hills ^ Park located in the northeastern portion of the City within the Calavara Hills 7-15 I* development. The City parks total about 30 acres of irrigated turf and about 22 acres of irrigated landscape. According to the data provided by the City of Carlsbad Parks and ** Recreation Department, the irrigation requirement for turf is 3.75 AF/AC/YR and for * landscape the requirement is 1.88 AF/AC/YR. L To meet the City's growth management program and park standard requirement, the City has several park projects planned. Of these projects, eight future parks are potential p reclaimed water markets. The Macario Canyon Park is the largest proposed park with y approximately 408 acres. The recreational amenities of the Macario Canyon Park will include a sports complexand an amphitheater complex. The reclaimed water demands p for the proposed parks were phased according to information provided by the City Parks fl and Recreation Department. Mr. Mark Steyaert, a park planner at the Parks and Recreation Department, suggested using conservative estimate of 80 percent of the total » future park acreage as irrigated turf and landscaped areas. Mr. Steyaert agreed that a If good approximation of the irrigation requirement is 2.5 AF/AC/YR. f" The Carlsbad State Park and the South Carlsbad State Park support only about a total of ** four acres of landscaped and irrigated areas according to the State Parks and Recreation Department and do not exhibit a substantial reclaimed water market. ^W ** Table 7-2 provides specific information for the existing and future parks. The estimated p, peak daily reclaimed water demands for the parks are 0.71 mgd in 1995 and 2.40 mgd in 4, 2015. F» 7.4.1.6 School Turf Irrigation M Ten schools within the Carlsbad Unified School District are located in the northwestern f portion of the City. The La Costa Meadows elementary school of the San Marcos Unified H School District, and the La Costa Heights elementary school and the newly constructed Mission Estancia elementary school of the Encinitas Unified School District are located in ** the southeastern portion of the City. The school yards total about 60 acres of irrigated ** turf. Based on the General Plan, sixteen schools are proposed at ultimate buildout: 10 elementary schools, 3 junior high schools, and 3 high schools.j^M ^m According to data provided by the Parks and Recreation Department, the irrigation — requirement for the school turf is 3.75 AF/AC/YR. Based on the "Water Reclamation |l Study Land Use Statistics" by the City of Carlsbad Planning Department in September 1982, proposed elementary schools were estimated at 10 acres each with 60 percent PI landscaping, junior high schools at 20 acres each with 50 percent landscaping, and ^ senior high schools at 50 acres each with 40 percent landscaping. The estimated peak daily demands for reclaimed water for school yards is 0.48 mgd in 1995 and 1.49 mgd in *» 2015. 7-16 m 7A.I.7 Landscaped Areas Irrigation ** The City of Carlsbad Parks and Recreation Department maintains several landscaped to and turf areas throughout the city. Most of these areas are in the northwestern portion of the city. Although the individual areas are quite small, they constitute a viable reclaimed W market because of their proximity to each other and other markets. The Safety Center • has the largest irrigated area and is located on El Camino Road, across from the Carlsbad Research Center. The estimated peak daily demands for reclaimed water for L these landscaped and turf areas maintained by the City are 0.27 mgd in 1995 and in 2015. Py 7.4.1.8 Residential and Commercial/Industrial Development Landscape Irrigation m Some of the larger future residential reclaimed water markets include Carlsbad || Highlands, Kelly Ranch, Evans Point, Aviara, and the La Costa developments. Existing developments that are potential reclaimed water markets because they are served by p separate irrigation meters include Tamarack Pointe, Falcon Hills, Sea Pines, Seacrest, h and Telescope Point. Both existing and future commercial/industrial developments with potential reclaimed water demands are located along Palomar Airport Road. l^w * Assumptions had to be made on the timing of future developments. The reclaimed water demands of residential developments larger than 100 acres were phased over ten years. P The entire reclaimed water demands of smaller residential developments were assumed to occur within five years of the start of construction. For simplicity, these demands were p. assumed to occur at the five year intervals shown in Appendix E. Table 7-3 summarizes ^ the assumptions made to represent ultimate buildout of the market area and to estimate the timing of reclaimed water demands based on the status of known projects. The p- . timing of commercial/industrial developments was based on the Zone 5 Local Facilities (* Management Plan. "* Unless specific data were available, the irrigated common space of residential *» developments was estimated to be 20 percent of the total acreage and the irrigated landscaped areas within commercial/industrial parks was estimated to be 15 percent of *" the total acreage. These percentages are based on discussions with property ** owners/managers and reviewing landscape plans for several developments. An irrigation rate of 2.5 AF/AC/YR was used to compute the reclaimed water demand for these markets. Residential landscaping represents estimated reclaimed water demands ** of 2.60 mgd in 1995 and 9.78 mgd in 2015 while commercial/industrial parks *. landscaping reclaimed water demands are estimated at 0.87 mgd in 1995 to 1.85 mgd in 2015. 7-17 p m 1 7.4.2 Industrial/Commercial Uses 7.4.2.1 Hughes Aircraft One of the larger water users in the City of Carlsbad is Hughes Aircraft. The larger water demands at Hughes Aircraft are for electronic equipment cleaning, scrubbers, boiler makeup water, and cooling tower makeup water. Pretreated potable water is used in the boilers and for the equipment cleaning and would not be replaced with reclaimed water. Reclaimed water could possibly be used for the scrubbers but Hughes Aircraft may be recycling water for this purpose. Cooling tower water is the largest water demand and the most likely use for reclaimed water at Hughes Aircraft. Currently potable water is allowed to concentrate four times prior to being wasted. Since the chemical constituents in reclaimed water are higher than potable water, using reclaimed water in the cooling towers may require more frequent wasting and additional chemical treatment. Discussions are continuing with the water specialist who oversees the cooling towers to determine the quantity of reclaimed water that could be used as well as the breakeven cost of reclaimed water. A preliminary estimate made by David McKinley, facilities project engineer specialist for Hughes Aircraft, of the potential demand of reclaimed water for the cooling tower is roughly 0.06 mgd. Table 7-3 Timing of Reclaimed Water Demands Size/Status Year of 50% Demand Year of 100% Demand Developments Over 100 Acres Final Map Approved Tentative Map Approved Being Processed, Proposed Developments Under 100 Acres Final Map Approved Tentative Map Approved Being Processed, Proposed Designated Residential Land 1995 2000 2005 2010 2000 2005 2010 1995 2000 2005 2015 7.4.2.2 San Diego Gas and Electric's Encina Power Plant San Diego Gas and Electric's (SDG&E) is also a major water user in the City. A large quantity of pretreated potable water is used for boiler water makeup at the Encina Power Plant. The amount of water required for the boilers is based upon the rate of power 7-18 m m I I generation. The maximum amount of makeup water required when all units are operating is in the range of 0.10 mgd to 0.17 mgd. Upon evaluating the quality of tertiary treated effluent from the Meadowlark WRF, which is essentially the quality of reclaimed water that would be available to SDG&E, the Environmental Department determined that using reclaimed water for boiler makeup water would require a significant capital expense and greatly increase operating costs. SDG&E estimated the equipment for pretreating the reclaimed water would cost approximately $600,000 and additional operation expenses would be about $60,000 per year. SDG&E recommended that a pilot study be performed prior to any use of reclaimed water and estimated the cost of this study to be approximately $100,000. Another concern of SDG&E regarding reclaimed water use is that they must meet their National Pollutant Discharge Elimination System (NPDES) permit requirements for ocean disposal. Additional cost would be incurred if the reverse osmosis brine required treatment prior to discharge as a result of reclaimed water use. Based on the information provided by SDG&E, no reclaimed water demands were associated with the Encina Power Plant for this study. 7.4.2.3 Encina Water Pollution Control Facility The Encina WPCF currently reclaims approximately 4.5 mgd of secondary treated effluent for odor scrubbers, washdown, engine cooling, and landscape irrigation; however, Encina also has a large demand for tertiary treated reclaimed water which is not being met. Currently, potable water is being used for the pump seal water system and chemical additions. Encina WPCF staff have estimated the current average and peak demands for the two uses to be 55 AF/YR and 80 AF/YR, respectively, and the future peak demand to be 110 AF/YR. Using this data, the peak daily tertiary reclaimed water demand was estimated at 0.07 mgd in 1995 and 0.10 mgd in 2015. 7.4.2.4 Commercial Buildings The General Plan designates about 1,600 acres as planned industrial use along Palomar Airport Road which includes the Carlsbad Research Center, Palomar Business Park, Carlsbad Airport Center, Carlsbad.Safety Center, Bircher Pacific Business Center, Faraday Business Park, Palomar Tech Center, and additional properties. Approximately 20 percent of this area is currently developed. Review of the Zone 5 Local Facilities Management Plan dated July 1, 1987 and the Zone 16 Acreage Summary, which together encompass the entire planned industrial area, indicate that 4,223,177 square- feet (SF) of industrial structures exist; 8,658,422 SF of industrial structures is unbuilt but already have either approved final maps, site development plans, planned industrial permits, or planned unit developments as of January 1, 1987; and 13,265,266 SF is future potential industrial structures. The only feasible market for reclaimed water use for a gray-water system would be future buildings that could be dualed plumbed. 7-19 «• To estimate the potential reclaimed water demand for use in gray-water system in future buildings, the following factors were used: ** • Net developable acres = 90% gross acres, L • SF of structures = 40% net developable acres, p, • 1 EDU = 1,800 SF of office and manufacturing structures 1 EDU = 5,000 SF of warehouse structures, E L. • Planned industrial land use = 50% office and manufacturing and 50% warehouses, • Total water use = 250 gpd/EDU, and • Gray-water system use = 60% total water use. F The estimated peak daily demand for reclaimed water for use within future buildings for • toilet flushing is 0.65 mgd in 2015. 7.4.3 Ecological Uses ^ 7.4.3.1 Stream and Lagoon Enhancement Both the San Marcos Creek and the Agua Hedionda Creek traverse the market area and IP» discharge into coastal lagoons. Growth of the riparian vegetation is restricted along the ^ segment of San Marcos Creek which traverses the La Costa Golf Course. Extensive dredging of the Agua Hedionda Lagoon and constant withdrawal for cooling water from *•* the lagoon has made it uniformly deeper than other coastal lagoons in the San Diego i» Region and have allowed continual tidal exchange. According to a draft report titled Stream Enhancement Potential, 1988 Through 2015, prepared by the San Diego RWQCB ^* in February of 1988, a stream enhancement discharge to the San Marcos Creek could ^ be incorporated into a comprehensive management plan for the Batiquitos Lagoon to create a brackish water marsh and true estuarine conditions. In the same report, the San Diego RWQCB stated that much of the Agua Hedionda Creek remains in a somewhat natural state, with good potential for enhancement but stream enhancement P, discharge to the Agua Hedionda Lagoon could cause the water quality of the lagoon to ^ suffer. «"• As part of the proposed Batiquitos Lagoon Enhancement Project, a 33-acre IH impoundment is proposed for a freshwater marsh which may require a supplemental source of freshwater to maintain its biological value. The project's Environmental Impact ** Report (EIR) anticipates that even using all of the flows from the San Marcos Creek may m be inadequate to keep the marsh supplied with water during the peak dry season. The EIR concluded that the feasibility of using reclaimed water as a supplemental source for ** the freshwater marsh would require further studies regarding expected water conditions ** at both the intake and discharge locations of the marsh. There may be a potential market 7-20 in for lagoon enhacement after further studies; however, since no definitive market currently exists, no water demands were attributed to this use. jp« I* 7.4.3.2 Groundwater Recharge f There are no major aquifers within the market area which presently provide a substantial ** portion of the water needs. The aquifers are relatively small, high in total dissolved solids (TDS), and primarily along the coastal areas. However, if the aquifers were recharged P with higher quality reclaimed water, they coufd be utilized to a greater extent for *i beneficial uses. P»^ In September 1987, the CWA prepared the San Diego Area Water Reuse Study, Volume I, Overview Report (Overview Report). The Overview Report evaluates potential p reclamation projects and includes detailed feasibility reports on the reclamation projects I, that are considered feasible within the next five to ten years. The report recognizes the Carlsbad planning area as a focal point of a large potential marketplace of reclaimed p water service to augment the public potable water supply. In regards to groundwater hi recharge, the Overview Report concludes that because of the limited groundwater storage, extensive management of the alluvial aquifers through recharge within the study f* area, recharge, storage, and exportation of groundwater may not be economically i» feasible. Since the feasiblity of a groundwater management program would be an extensive study in itself and has not been identified as a likely market for reclaimed water * in previous studies, groundwater recharge was dismissed as a potential reclaimed water ** market. Pm 7-21 « CHAPTER 8 ** ALTERNATIVE PROJECT DESCRIPTION r» *• 8.1 PLANNING AND DESIGN CRITERIA Developing alternative plans to serve reclaimed water to the study area required establishing certain criteria applicable to the preliminary design of major facilities. The - design criteria presented in this Chapter apply to preliminary design and layout of the te proposed facilities. Approximations of size, location, and type of construction are present only in sufficient detail to compare alternatives. A detailed engineering study will — be made during the preparation of design drawings and specification which will * determine the final location, size, and type of construction. ~ 8.1.1 Design Period *•> According to the SWRCB Water Reclamation Loan Program Guidelines, the period over ""* which a water management system is evaluated for cost effectiveness begins with the ** systems initial operation and is defined to be 20 years. The planning period for this ^ study extends from 1997, the year the proposed facilities described in the Encina Basin Water Reclamation Project, Phase I Program Facilities Plan (Encina Basin Phase I *"* Facilities Plan) by John S. Murk Engineering, Inc. could be expanded through 2017. _ Phase I of this master plan incorporates the Encina Basin Phase I Facilities Plan which is ^ expected to be complete by 1992. — 8.1.2 Supply Methodology M There are three options that exist to match reclaimed water supply and reclaimed water """ demand when the seasonal peak demands exceed the reclaimed water production. ** These options are to: """ 1. Provide seasonal storage if the reclaimed water production is sufficient to meet *" annual demands, 2. Serve fewer users in the system such that the peak demands can be met entirely *"" by the reclaimed water supply, and to 3. Serve additional users in excess of reclaimed water supply and meet the peak demands with supplemental potable water. *, Since reclaimed water can be in ample supply when the Encina WPCF is employed, these options may not be applicable. For this master plan, it is assumed that reclaimed *" water facilities in each of the alternatives will be able to meet the peak seasonal demands 8-1 m m IM of the markets. The methodology used for the development of the alternatives is that of a water purveyor; that is, reclaimed water is to be delivered at a specified minimum f1 pressure and at the required peak flowrate to each user. 8.1.3 Reclaimed Water Demand Variations *" A majority of the reclaimed water is intended to be used for irrigation purposes, as ^ presented in Chapter 7. Irrigation water demands are non-uniform, varying diurnally as well as seasonally. P* 8.1.3.1 Seasonal Reclaimed Water Demands As discussed in Chapter 7, seasonal variations in irrigation demands are induced by m weather effects and the nature of various crops. Peak applications are applied during to the dry summer months, and low applications occur during the wet winter months. Reclaimed water distribution systems must be designed to deliver peak and low flows to P accommodate these non-uniform seasonal demands. to 8.1.3.2 Diurnal Reclaimed Water Demands P • In addition to seasonal demand variations, daily variations in reclaimed water demands also impact the design of the reclaimed water distribution system. The majority of ? irrigation demands are usually scheduled during the late evening and early morning hours, within an 8 to 10 hour period. In fact, for areas available to public access, the m California DHS requires irrigation with reclaimed water scheduled during periods of to minimal public use. In contrast, industrial reclaimed water demands typically occur during weekday, daytime hours. Because industrial demands in the study area are IP much smaller than potential irrigation demands, the design of the reclaimed water m distribution facilities will be governed by the peak irrigation demand. ** 8.1.4 Storage Requirements Seasonal storage is not required since the peak seasonal demand will be met with m reclaimed water supply. Since seasonal storage will not be provided, reclaimed water will * be produced only to meet the peak seasonal demand. 3 Operational storage is provided for the varying daily demands of a reclaimed water distribution system. Storage of approximately two-thirds of the peak daily demand is p required based on the assumption that irrigation would occur during an 8-hour period. H Operational storage is also required for flow equalization at the treatment facility since production of reclaimed water varies throughout the day. m 8.1.5 Pressure Requirements <* Reclaimed water must be delivered to a market at an adequate pressure. Where H reclaimed water is replacing a potable water demand, water pressures at least equal to *>» 11111 8-2 j| the pressure of the potable water system (40 to 75 psi) are typically required. A market service area, or specific elevation zone, was established for this Master Plan with the pi hydraulic grade equivalent to existing or proposed potable storage reservoirs. The li elevation used in the analysis was the average water level of storage reservoirs in that particular zone. fc This study does not attempt to design individual irrigation systems, however even the preliminary design of the reclaimed water distribution mains (including the alignment, r capacity, head losses, etc.) must take into account the pressure requirements of the *• service area. i It was assumed that the minimum pressure delivered to a market would be 50 psi and the maximum would be 120 psi. If the pressure is below 50 psi, booster pumps would m be required and if over 120 psi, a pressure reducing valve would be used. The elevation H of proposed storage reservoirs and extent of each zone was chosen so that the majority of the markets within that zone could be served without utilizing pressure reduction in valves or booster pumps. M 8.1.6 Pumping Requirements m m The water level in the reservoir would control the operation of the pump stations. To replace the amount of water withdrawn from the storage reservoir on a peak summer * day, the pumps would operate continuously at a constant rate over a 24-hour period. ^* During times when reclaimed water demands are less than the peak summer demands, the pumps would only operate for the time required to fill the reservoir. These pumps L would be variable frequency driven to accommodate the differential total dynamic head (TDH) conditions existing during the irrigation and non-irrigation periods. ^ Booster pumps were included in the distribution system if the available pressure at the user's site was less than 50 psi (115 feet of TDH). Booster pumps were sized to meet m the user's peak hour demand rate at 75 psi (175 feet of TDH). The booster pumps m would operate as needed during the 8-hour irrigation period. The irrigation booster pumps would be either operated manually or interconnected with the user's automatic P irrigation system or supply system, in the case of industrial and commercial users. 8.1.7 Distribution Pipeline Criteria • Distribution pipelines conveying reclaimed water to storage sites must be sized to meet the peak day demands. In contrast, conveyance pipelines from reservoirs to an E individual user's site must be sized to deliver reclaimed water at the peak hour flowrate, which for this study is three times the peak day demand since use was assumed to in occur during an 8-hour period. Suitable materials for distribution pipelines include polyvinyl chloride (PVC), ductile iron m pipe (DIP), cement lined and coated (CML&C) steel pipe, and concrete cylinder pipe p ll (CCP). PVC nominal pipe sizes were used for lines 21-inches in diameter and smaller and CCP nominal pipe sizes were selected for lines 24 inches and larger. Distribution E pipeline sizes were determined based on a Hazen-Williams friction coefficient (C) of 120. Friction losses were allowed to range between 2 and 10 feet per 1,000 feet of pipeline which resulted in velocities of less than 10 feet per second (fps). p» * 8.2 ALTERNATIVE PROJECT DEVELOPMENT AND DESCRIPTION ** The alternatives developed were based on producing sufficient reclaimed water to meet *• the peak seasonal demands of the majority of the potential reclaimed water markets in the study area. Since the basis of this plan is to meet the peak flows, and the Title 22 treatment facilities are expected to be sized for these peak demands, the alternative projects were developed based on the following assumptions: *• to • The Title 22 treatment facilities will not be used on a continuous basis throughout the year, but will process reclaimed water to meet the peak seasonal demands. During pt the heavy irrigation demand period from June through September, these facilities * would operate nearly continuously. At certain times of the year when the storage reservoirs are full and there is little demand for reclaimed water, these facilities would m- not operate. m • Records for the Meadowlark Water Reclamation Facility (WRF) indicate about 20 m percent of the flow is wasted as solids to Encina. Therefore, to account for solids * wasted to the Encina WPCF, the reclaimed water available from the Gafner Wastewater Treatment Plant (WTP) and Meadowlark WRF plants was estimated at L 20 percent less of the present capacities of 0.75 mgd, and 2.0 mgd, respectively. Although the Lake Calavera Hills WRF has on-site solids handling facilities, the m amount of reclaimed water produced after solids are wasted was estimated in the Ig same manner. pi • The proposed storage facilities and distribution would be sized to deliver the peak tt seasonal reclaimed water demand in an 8-hour irrigation period. Since the reclaimed water pump station at the site of the Title 22 facilities will operate continuously, and at ff full speed during the peak demand periods, the storage reservoirs will provide two- * thirds of the flow demand rate, with the pump station providing the other one-third of the flow demand rate. " • The reclaimed water treatment and distribution facilities identified in the Encina Basin Phase I Facilities Plan and the Aviara Reclaimed Water Facilities Plan, prepared by 2 Luke-Dudek, would be constructed as Phase I of the ultimate reclaimed water facilities. m H • Pipeline alignments were chosen to form logical distribution systems to minimize pipe runs and sizes. For the most part, pipelines run in either existing or proposed m streets. It should be noted that there is the potential to use abandoned water lines 3.4 on m as they become available. Hydraulic analysis of the distribution system was done using the University of Kentucky KYPIPE network analysis software. Pipe lengths P and diameters, market flow demands, reservoir locations, pressure reducing ^ stations, and pump stations were modeled in the computer analysis. f • Points of user connections were located at about the center of the market for the ** purpose of developing a network to be used for KYPIPE input and do not necessarily ^ represent actual connection points. Likewise, the pipe lengths and diameters , determined and presented from this layout and KYPIPE analysis do not intend to represent final pipeline lengths or diameters. IP* te • Reservoir locations were set so that the hydraulic grade line established would provide adequate pressures for the majority of the markets in that service zone m without the need of auxiliary pumping. m • While reclaimed water distribution systems presented are based on a certain degree P of refinement to arrive at a realistic and workable distribution network, they were not * optimized, and there are probably variations in the alignment of pipelines, and the location and height of reservoirs that would result in a more cost effective reclaimed * water distribution system.m 8.2.1 Development of Alternatives|^M m The alternatives were developed according to their relative characteristics for location of p* proposed Title 22 facilities, location of markets based on the San Diego RWQCB's ^ Comprehensive Water Quality Control Plan Report, San Diego Basin (9) (Basin Plan) total dissolved solids (TDS) restrictions for groundwater, and location and number of — proposed reclaimed water reservoirs. The alternatives were based on the following t, criteria: ** • Location of proposed Title 22 facilities; the possible sitings were (1) in the vicinity of <* the Encina WPCF only and (2) at both the Lake Calavera Hills WRF and in the vicinity of the Encina WPCF,j^w * • Location of markets based on the Basin Plan's TDS restrictions; the possible markets served were (1) all markets within the study area regardless of Basin Plan y TDS limitations and (2) all markets except irrigation markets within the area with groundwater TDS limitations of 1,200 mg/l, and m ^1 • Location and number of proposed reclaimed water reservoirs; the possible storage scenarios were storage at (1) the existing Mahr Reservoir only, (2) the existing Mahr p» Reservoir and a new reservoir in the northeast of Carlsbad, (3) the existing Mahr m Reservoir, and an existing reservoir in the southwest portion of Carlsbad with an intermediate pump station, and (4) the existing Mahr Reservoir, a new reservoir in * the northeast section of Carlsbad, and an existing reservoir in the southwest portion B of Carlsbad area with an intermediate pump station. 8-5 m 8.2.2 General Description of Alternatives i^R m Four alternatives were developed by combining the criteria listed above for the location of proposed Title 22 facilities and the location of markets as follows: fM m Alternative 1 ** • Proposed Title 22 facilities located in the vicinity of the Encina WPCF ** • All markets served Alternative 2to 0. • Proposed Title 22 facilities located in the vicinity of the Encina WPCF • All markets served except irrigation markets within the area with groundwater TDS limitations of 1,200 mg/l i* m Alternative 3 * • Proposed Title 22 facilities in the vicinity of the Encina WPCF m • Proposed Title 22 facilities at the Lake Calavera Hills WRF • All markets, servedm • Alternative 4 ^ • Proposed Title 22 facilities in the vicinity of the Encina WPCF • Proposed Title 22 facilities at the Lake Calavera Hills WRF p, • All markets served except irrigation markets within the area with groundwater TDS g limitations of 1,200 mg/l S Each of the above alternatives would incorporate the facilities proposed in the Encina Basin Phase I Facility Plan. The facilities that would be incorporated from the Encina Basin Phase I Facilities Plan are: m H • Meadowlark reclamation facility; new effluent screening facility, additional effluent pumps, and a new force main from Mahr Reservoir to the Meadowlark WRF, ^^B *• • Gafner WTP; new tertiary treatment facilities to provide Title 22 effluent, a new effluent pumping station, and a new force main, «La Costa (North) facilities; a supply control system, 2,000 feet of 8-inch pipeline, p 3,200 feet of 10-inch pipeline, and a 0.34 million gallon (MG) reservoir, m • La Costa (South) facilities; existing pump station modifications, 300 feet of 12-inch *• pipeline, 8-6 • CALTRANS facilities; a supply diversion structure, a 0.40 MG storage reservoir, a S distribution pump, and 4,000 feet of 8-inch pipeline, • Frazee facilities; a supply system 1,000 feet of 10-inch pipeline, and a distribution ^ pump station, • Ukegawa facilities; a supply pump station, 200 feet of 6-inch pipeline, a 0.07 MG * storage reservoir, and a distribution pump station, and p • Aviara facilities; a supply pump station, 800 feet of 12-inch pipeline, a 1.39 MG L storage reservoir, and a distribution pump station. PI In each of the alternatives, the Gafner reclamation facilities constructed for Phase I In would serve the on-site irrigation demands as well as a portion of the La Costa Golf Course irrigation demands. Also, Meadowlark effluent would be pumped to Mahr f» Reservoir from where it would enter the distribution system. Table 8-1 summarizes the Hi amount of reclaimed water that would be produced at each reclamation facility for each alternative on a peak summer day. It should be noted that the flows listed for the Gafner, p Meadowlark, and Lake Calavera Hills facilities are less than the design capacity to ** account for wasted solids. £ Discussions with Encina WPCF personnel has indicated that the Title 22 facilities and the ™ distribution pump station required to use Encina WPCF effluent must be located off-site. p Although further study is required to determine the actual area required and an L appropriate nearby site, a preliminary estimate of the size must be made for facility costs. The upgraded Encina WPCF for all alternatives would include filtration, coagulation, P. flocculation, and disinfection facilities. Based on preliminary calculations and layouts, ^ these facilities would require approximately 3 acres. f» Each alternative would serve several markets located at higher elevations in the western if portion of the study area. These markets would form a separate distribution system. The system would include a new pump station at Mahr Reservoir to pump reclaimed m water to a new reservoir at elevation 740 feet, Dependent upon the markets served, the fc reservoir would be 1.5 MG for Alternatives 1 and 3, and 1.2 MG for Alternatives 2 and 4. H 8.2.3 Description of Subalternatives P Several distribution systems were analyzed by considering a number of storage Subalternatives. The ^ Subalternatives were not only dependent upon the location and number of storage reservoirs, but also t pipeline diameters which were varied to allow different amounts of reclaimed water from each reservoir. p The Subalternatives use a combination of existing and proposed storage reservoirs.

It has a storage volume of 54 MG which is sufficient operational storage for the entire study area. Approximately *** 12 to 15 MG of operational storage is required in the Mahr Reservoir for the alternatives *• considered. Each subalternative would use the Mahr Reservoir as a primary reservoir. ^ Two existing potable water reservoirs in the southwest portion of the study area could possibly serve as reclaimed water storage reservoirs.tat *. These twin reservoirs, each 1.25 MG, are owned by the Carlsbad Municipal Water ^ District (CMWD) and located just south of Palomar Airport Road and west of El Camino Real. These reservoirs may be available if CMWD constructs a new larger reservoir as *~ specified in their master plan. An intermediate pump station would be located at the twin to. reservoirs site, which would pump only the portion of reclaimed water for the market in the southern area. The subalternatives that were analyzed are described below. !•» *• Subalternative A m • Existing Mahr Reservoir serves the southern and northern areas * • New reservoir in southeast serves higher elevations • Encina pump station: 2,600 Hp (13,500 gpm, 570 FT TDH) s • 6 booster pumps pi Subalternative B •• Existing Mahr Reservoir serves the southern area and a portion of the northern area m • New reservoir in northeast (2.6 MG) serves a portion of the northern area H • New reservoir in southeast serves higher elevations • Encina pump station: 2,900 Hp (13,500 gpm, 635 FT TDH) P .7 booster pumpsm P 8-8to w Subalternative Cp "* • Existing Mahr Reservoir serves a portion of the southern and northern areas • Existing twin reservoirs in southwest (2.5 MG) serve a portion of the southern area f* • New reservoir in southeast serves higher elevationsi"1 • Encina pump station: 2,600 Hp (13,500 gpm, 570 FT TDH) p, • Intermediate pump station: 440 Hp (5,800 gpm, 225 FT TDH) ^ • 9 booster pumps pi Subalternative D b • Existing Mahr Reservoir serves a portion of the southern area m • New reservoir in northeast (3.8 MG) serves most of the northern area m • Existing twin reservoirs (2.5 MG) in southwest serve a portion of the southern area • New reservoir in southeast serves higher elevations f* • Encina pump station: 2,100 Hp (13,500 gpm, 470 FT TDH) h • Intermediate pump station: 440 Hp (5,800 gpm, 225 FT TDH) • 9 booster pumps m m m m to Pi m p m m mm it pjL 8-9 B B £ CHAPTER 9 ALTERNATIVE PROJECT ANALYSIS 9.1 BASIS OF COST ESTIMATES The capital costs and operational and maintenance (O&M) costs that are presented in y this Chapter are presented based on the preliminary layout of proposed facilities. Since the costs are based on very preliminary layouts, it can be expected that refinements in p the detailed design may have an impact on these costs. tb 9.1.1 Capital Costs m H The capital costs information is based on recent bidding data and supplemented by bonding cost estimates used by the City and County of San Diego. Capital costs in this p report include the construction costs as well as costs for engineering, legal and m administration, construction management, and contingencies. "" 9.1.1.1 Construction Costsm 9.1 .1 .1 .1 Construction Cost Index ym Since future construction costs are expected to increase with the change in the p, economy, a means to index the costs to a baseline is used. The Engineering News ^ Record Construction Cost Index (ENR CCI), which is computed from prices of construction materials and labor, is used as the cost index for this report. The ENR CCI jj is based on a value of 100 in 1913, and has steadily risen to approximately 5,850 for Los § Angeles in June 1989. p 9.1.1.1.2 Distribution Pipeline Costs It was determined that it was most economical to use polyvinyl chloride pipe (PVC) for lines 21 inches and smaller and concrete cylinder pipe (CCP) for 24 inch and larger distribution lines. In-place costs for each pipe size was calculated by estimating separate costs for material, basic installation, pavement cutting and replacement, traffic control, and appurtenant valves and fittings. Right-of-way costs were not included. Based on this analysis, the rounded construction costs used in this report for pipelines are presented in Table 9-1 . Due to the uncertainty of the costs that would be required to y utilize abandoned pipelines, no costs were attributed for their use. p 9.1.1.1.3 Pump Station Costs| Costs for pump stations are developed individually for the specific pump station flow and P system head requirements. An approximation of the costs of pump stations is presented * C 9'1to p m H in Figure 9-1 (A). Because there are a number of specific factors for each pump station situation that affect the construction costs, the costs presented should only be used as P an order of magnitude estimate of costs. The costs developed for the specific pump ** station requirements include vertical turbine pumps with electric motors, suction and discharge piping and valving, motor control center and instrumentation, and housing in a P concrete block building. m 9.1 .1 .1 .4 Booster Pump Costs ••A construction cost curve was developed for booster pumps and is shown in Figure 9-1 m (B). The construction cost for various size pumps was based on exterior siting of factory I, assembled package units. The factory assembled units consist of horizontal split-case pumps and include all controls and valving. Sitework and electrical hookup costs are P included in the costs. m 9.1 .1 .1 .5 Storage Reservoir CostsP» ** Storage reservoirs were sized to meet the peak day operational needs of the user or cluster of users. As mentioned previously, this will require 16 hours of storage for users m with an 8-hour daily irrigation schedule. It was assumed that storage reservoirs are 111 covered reservoirs, constructed of steel. Construction costs were estimated by using a m unit cost of $0.50 per gallon which includes land costs, sitework, yard piping, foundation, erection, costing, and cathodic protection. p 9.1.1.1.6 Land Costs m Land costs are included in the estimate for off-site tertiary treatment facilities. Land costs «) were assumed to be $250,000 per acre near the Encina WPCF. Land costs were not ll included for pipelines since it was assumed they will be constructed within public right-of- ways. Neither were land costs included for irrigation booster pumps because it was P! assumed that they will be located on the user's property. Access roadway costs are not M included for any components of the distribution system. J 9.1 .1 .2 Contingencies ^ The capital costs include a contingency of 15 percent of construction costs for pipelines ^ and reservoirs. A 20 percent contingency was used for booster pumps, pump stations, and tertiary treatment facilities. The contingency accounts for unforeseen difficulties, nt modifications made during final design, and uncertainties unavoidable during preliminary 0 design. This factor allows for additional costs resulting from unusual foundation conditions, special construction methods, and variations in final lengths, diameters, and « depths of pipelines. 9-2 §o COou o ICO Oo Io o u ICO oo 100 200 150 100 4 5 6 7 8 9 10 CAPACITY.

These costs vary considerably based on the size and complexity of the project. For this study, 20 percent of the construction cost was used ffi for estimating a combined costs for engineering and construction management for • pipelines and reservoirs, and 25 percent for booster pumps, pump station, and tertiary treatment facilities. Two percent of the construction cost for all facilities was used to E account for legal and administration costs involved in the implementation of the project. 9.1.2 Operational and Maintenance Costs Included as O&M costs are labor, energy, supplies, administration, and other incidental costs. For all pipelines and reservoirs, the annual O&M cost has been assumed to be 0.3 percent of the construction cost. For pumps and tertiary treatment facilities, the annual O&M cost was based on the projected energy usage at a cost of $0.12 per kilowatt-hour, plus 1.5 percent of the construction cost. 9-4 m m m mk | m to F° L P» L 9.2 SUBALTERNATIVE PROJECT ANALYSIS To avoid numerous alternatives, the subalternatives were applied to Alternative 1 and compared on the basis of capital costs and non-monetary considerations. The most feasible subalternative was then applied to the other three alternatives. The four alternatives were then compared on the basis of an economic and non-economic analysis. 9.2.1 Capital Cost Comparison As stated, each subalternative was based on Alternative 1. That is, it was assumed that the tertiary treatment facilities would be located near the Encina WPCF, all markets would be served, and the reservoirs included the existing Mahr Reservoir and a new 1.5 million gallon (MG) reservoir to serve the higher elevations. The treatment facilities would be identical for each subalternative and therefore excluded from the capital costs of the subalternatives. Also, Phase I costs were also excluded for the same reason. Costs were estimated for distribution pump stations, pipelines, booster pumps, and reservoirs. The capital costs are presented in Table 9-2. Table 9-2 Distribution System Capital Costs of Storage Subalternative Capital Costs, $1,000 Subalternatives Pipelines Reservoirs Pump Stations Total A B C D 36,990 39,260 35,990 35,990 1,020 1,930 1,020 2,330 2,820 2,900 3,770 3,770 40,830 44,080 40,780 42,090 P m The pipeline costs constitute over 85 percent of the total distribution system costs in each of the subalternatives. Subalternatives lowest pipeline cost, primarily because only a portion of the flows would be pumped from the intermediate pump station to the Mahr Reservoir, thus requiring a smaller diameter pipeline for that distance. Even with the cost of the additional pump station, Alternative C has the lowest capital cost, $40,780,000, and Alternative A has the second lowest capital cost, $40,830,000. Alternative B has both the highest pipeline cost and total capital cost. 9-5 m m m 9.2.2 Non-Monetary Considerations m The non-monetary considerations in selection of the best apparent storage h subalternative is based on the comparison of the favorable and unfavorable aspects resulting from that subalternative. As presented in the previous chapter, the primary P difference between the subalternatives is in storage at Mahr Reservoir alone or storage • at Mahr Reservoir in conjunction with either a new reservoir in the northeast or the twin ,„ reservoirs in the southwest. In this comparison a simplified ranking matrix, presented in Table 9-3, was developed to p, compare the results of the alternatives. The factors used in the matrix are constrained to ^ environmental impacts during construction and operation, aesthetics of the facilities, and implementation ability. Each factor was given equal weight with a number from 1 to 5, m with 1 representing the best rating. Table 9-3 i Non-Monetary Benefit Ranking Matrix of Subalternatives » Subalternative Factor A B C D p ; m Environmental Impact 1244 Aesthetics 1545 H Implementation 1253 Total 3 9 13 12 In all the subalternatives, there will be an adverse impact on the environment due to the B noise and dust associated with construction of the reservoir and pump station, but the * subalternatives with greater facilities to be constructed would create more impacts. In addition, some adverse environmental impact can be expected with the storage of B reclaimed water in an open reservoir. In terms of aesthetics, all the subalternatives will have some adverse impact since all will have new above grade structures. Again, the •i impact would be greater for those subalternatives that require the most facilities.i All of the subalternatives for storage of reclaimed water are technically feasible, but the m unanswered question of the availability of the twin reservoirs in the southwest portion of IK the City makes the feasibility questionable of subalternatives using these reservoirs. if 9.2.3 Summary of Subalternative Project Analysis The storage subalternatives are listed in Table 9-4 according to the ranking from the P capital cost comparison and non-monetary considerations developed in the previous ™ sections. m * 9-6 Table 9-4 Subalternative Project Analysis Summary Rank Capital Environmental/Aesthetics Cost Implementation 1 C A 2 A B 3D D 4 B C *» The capital costs of the subalternatives do not vary considerably; the cost difference to from the most expensive subalternative to the least expensive subalternative is less than ten percent. Although both Subalternatives A and B do not use the twin reservoirs, f" Subalternative A appears to be the most balanced alternative in terms of both capital It cost and ability to be implemented. E 9.3 DESCRIPTION AND COSTS OF ALTERNATIVES From the above analysis, it was determined that using only the existing Mahr Reservoir L (in addition to the reservoir required to serve the higher elevations) would provide the most suitable storage and distribution system. The next section briefly describes the P, distribution system for each alternatives. The costs for each alternative are also ^ presented. ~ 9.3.1 Description of Alternatives tec The distribution facilities for Alternative 1 are shown in Figure 9-2. A 30- and 36-inch *~ pipeline comprise the backbone of the system which extends from the distribution pump t» station near the Encina WPCF to the Mahr Reservoir, paralleling the existing Meadowlark WRF failsafe outfall most of the distance and branches off to the north. An abandoned "" 20-inch pipeline in El Camino Reservoir is utilized from Palomar Airport Road to *"•• Tamarack Avenue. The southern portion of the study area is served from pipeline ^ branches extending from this pipeline. The northern portion is served by a 30-inch pipeline extending from Palomar Airport Road to El Camino Real. The total annual ** demand would be 11,478 AF/YR. A peak summer day would require approximately 21.4 «-. mgd of reclaimed water. to The markets at higher elevations along the western edge of the study area would be *• served by a pump station at Mahr Reservoir and a new reservoir. Most of the markets a, served by this system would be future residential developments and future commercial developments along Palomar Airport Road. Alternative 1 would require approximately 14 *" MG of storage at Mahr Reservoir. 9-7 2500 5000 FT. o o LAKECALAVERA HltLS LEGEND — — EXISTING PIPELINE STUDY AREA/CITY OF CARLSBAD PROPOSED RECLAIMED WATER PIPELINE EXISTING WASTEWATER RECLAMATION FACILITY EXISTING STORAGE RESERVOIR PHASE I STORAGE RESERVOIR PHASE I PUMP STATION PROPOSED STORAGE RESERVOIR PROPOSED PUMP'STATION A6 P8• • POTENTIAL RECLAIMED WATER MARKETS AGRICULTURAL A1VALDMA A2KATOFARMS A3UKEOAWAFARMS A4FRAZEEFLOWERS A9TABATO A8PMTO FLOWERS A7DENMS FLOWERS Aa THOMPSON ROSE COMPANY A9 FERNANDEZ A10 LA COSTA WHOLESALE FLOWERS All STCNOORFF A12BRESSC RANCH A13L» 8 FLOWERS A14SANTANA GOLF COURSES 0 1 LAKE CALAVERA OOLF COURSE 0 2 RANCHO CARLSBAD COUNTRY CLUB 0 3 MeCLEUAN GOLF COURSE G 4 AVIARA GOLF COURSE 0 5 LA COSTA COUNTRY CLUB FREEWAY F114 INTERCHANGES F 21-5 RIGHT-OF-WAY PARKS PtMAGEE Pa HOLIDAY P 3 PINE FIELD P 4 CARLSBAD BEACH STATE PARK P 5 LARWIN COMMUNITY PARK PS CALAVERA HILLS P 7 LACUNA RIVIERA P 8 MACARO CANYON DEVELOPMENT P9 CANNON LAKE P10 ALTA MIRA COMMUNITY PARK P11 SOUTH CARLSBAD BEACH STATE PARK P12 SPECIAL USE AREA P13 ALGA NORTE COMMUNITY PARK P14 CARRILLO PIS LA COSTA CANYON PIC STAGECOACH SCHOOLS S 1 ARMY NAVY ACADEMY S 2 BUENA VISTA ELEM.

ASSOCIATES, me. 9-7 m The distribution facilities proposed for Alternative 1 are summarized below: S « New reservoir: 1.49 MG • 6 on-site booster pumps • Mahr pump station: 100 Hp (1,482 gpm, 200 FT TDH) E • Encina pump station: 2,600 Hp (13,500 gpm, 570 FT TDH) • • Phase I facilities E The distribution facilities for Alternative 2 are shown in Figure 9-3. Since fewer markets would be served if irrigation is restricted from a portion of the study area because of total p, dissolved solids (TDS) restrictions, a smaller pipeline would be required from the jy distribution pump station near the Encina WPCF to Mahr Reservoir. This pipeline would be 20- and 24-inch pipe. Two portions of the abandoned pipeline in El Camino Real are p utilized: a section approximately 4,500 feet extending from Palomar Airport Road to Jy Faraday Avenue and a section approximately 6,400 feet extending from Cannon Road to Tamarack Avenue. Approximately 11 MG of storage would be required for Alternative 2 •" at the Mahr Reservoir. The annual demand for Alternative 2 would be 9,313 AF/YR. The distribution facilities for Alternative 2 include the following: !"• • New reservoir: 1.18 MG • 4 on-site booster pumps P • Mahr pump station: 85 Hp (1,200 gpm, 210 FT TDH) *" • Encina pump station: 2,000 Hp (10,000 gpm, 590 FT TDH) „ • Phase I facilities *" The distribution system for Alternative 3 would be similar to Alternative 1. A small — distribution pump station approximately 90 Hp (490 gpm, 530 FT TDH), would be ta required at the Lake Calavera Hills WRP. The Encina WPCF distribution pump station, the Mahr Pump Station, and the new reservoir would be the same or approximately the """ same size as described for Alternative 1. Also, the amount of storage required at Mahr *. Reservoir for Alternative 3 would be just over 13.5 MG. *" The distribution system for Alternative 4 would be similar to Alternative 2 except with a *• distribution pump station at Lake Calavera Hills WRP about the same size as that required for Alternative 3. Alternative 4 would utilize just under 10.4 MG of the Mahr "" Reservoir.m P, In addition to the water reclamation project alternatives described in the previous ^ paragraphs, there is a "No Project" alternative. The "No Project" alternative would consider that all future needs that could be met with reclaimed water would be provided PI by potable water. The net effect of this alternative would be that in the future local and to regional potable water storage, transmission and distribution facilities would need to be added to provide for the future water demands. P m r 9.9IH I 9.3.2 Alternative Costs R A summary of the costs for each alternative is presented in Tables 9-5 through 9-8. ™ Detailed cost estimates are provided in Appendix F. The capital costs presented in the p tables are for the facilities proposed in this report and do not include costs for Phase I Jy facilities. Likewise, the O&M costs presented would be additive to the Phase I O&M costs. The costs presented do not include annual costs for the purchase of reclaimed p water from the Encina Joint Powers Agency JPA, Leucadia County Water District |i (LCWD), or Vallecitos Water District (VWD) nor were costs included for the use of abandoned waterlines. Alternative 3, which would serve all the market area and would p utilize reclaimed water from both the Encina treatment plant and the Lake Calavera WRP, m would have the highest capital costs and O&M costs. Since Alternative 2 and 4 would not serve irrigation markets in the area with TDS limitations, the pipeline costs are IP considerably less than the other two alternatives. As a result, Alternative 2 has the least • capital costs as well as the least O&M costs. f 9.4 ECONOMIC ANALYSISm __ 9.4.1 Methodologyfl^w L The objective of an economic analysis is to determine the optimal use of resources; that p is, which particular available alternative provides the very best use of resources in the |j sense of maximizing the net gain to society. In this section, an economic analysis is presented for each alternative. The economic analysis is based on the cost estimates p» presented in Tables 9-5 through 9-8. Cost escalation, that is inflation of wages and ^ prices, is excluded from the analysis since changes in the general level of prices will not effect the results of the economic analysis. Interest incurred during construction was f" excluded. The capital costs were annualized over a 20 year planning period. A 7.5 L percent discount rate was used to be consistent with the Encina Basin Facilities Plan by John S. Murk Engineers, Inc. The discount rate is the expected rate of return from the P project investment. Although the nutrient value of reclaimed water would be a benefit that ^ could easily be assigned a cost, it was excluded from this analysis. !»"• Salvage values for capital facilities were computed on the basis of an appropriate useful """ life of the project facility during the 20-year planning period using straight-line _ depreciation. A period of 50 years was used for the useful life of the pipelines and jy reservoirs, and 30 years for booster pumps, pump stations, and tertiary water treatment facilities. To calculate the salvage value of land for off-site tertiary treatment facilities, the P» land value was appreciated at a compound rate of 3 percent annually over the planning Ib period. 9-10 m P m m Table 9-5 Alternative 1 Cost Summary Facility Construction Costs Including Contingency $1,000 Engineering, Const.

In calculating the annual project cost the annualized 111 capital cost, the annual O&M costs, and the annualized salvage value (a negative cost) p were summed. Initially a unit cost was calculated based on the additional quantity of H reclaimed water provided by the proposed facilities and the costs presented in Tables 9- 5 through 9-8. The additional quantity would be the total reclaimed water demand of the ni system (11,478 AF/YR for Alternatives 1 and 3 and 9,313 AF/YR for Alternatives 2 and 4) |l less the 2,450 AF/YR supplied to the Phase I users. These quantities are based on reclaimed water demands projected for 2015. In this manner, only the additional costs P» imposed by the facilities proposed in this Master Plan which would expand upon the to Phase I facilities are initially compared. It should be noted, that the economic analysis assumes the facilities would be constructed at the same time without phasing, except for ** Phase I facilities. *In the "No Project" alternative, which assumes that all future needs that could be met with ^ reclaimed water would be provided by potable water, future local and regional potable * water storage, transmission and distribution facilities would need to be added to provide for the future water demands.1^^ Ig According to the County Water Authority, the incremental cost of providing potable p, water, that is the avoidance cost of construction of these facilities, is estimated to be ^ about $690 per acre-feet for the water development costs, the MWD delivery cost, and the CWA delivery cost. Not included is the retail agency capital costs, and operational f- and maintenance costs. The cost of the "No Alternative" project then, less the CMWD ta costs, would be $7,590,000, based on the construction of future potable water facilities to provide for 11,000 acre-feet of demand per year. *** *. 9.4.2 Results of Analysis r The results of the economic analysis are presented in Table 9-9. Alternative 3 has the *" highest distribution unit cost and Alternative 4 has the highest treatment and combined ^ unit cost. Alternative 1, which would distribute reclaimed water produced at the Encina WPCF to the entire study area would have the least distribution, treatment, and *"" combined unit cost. «• ^ As stated, the unit costs represent the additional costs without regard to capital and O&M costs of Phase I facilities. To compare the alternatives in a more realistic manner, *• the O&M costs incurred to continue to supply the markets served by Phase I facilities M should be considered. The capital costs of the Phase I facilities would be considered sunk costs and not used in the economic analysis since it is assumed that these facilities * would be constructed prior to and regardless of the facilities proposed in this Master * Plan. However, the salvage value of the Phase I facilities should be used. T The O&M costs, capital costs, and useful lives of the Phase I facilities were obtained from 9-14 m Appendix F of the Encina Basin Facilities Report. The O&M costs were adjusted slightly. The Encina Basin Facilities Plan estimated the cost to produce tertiary treated reclaimed P water to be $100/AF at the Meadowlark and Gafner WRP. This unit cost was applied to "B the quantity of reclaimed water to be used by Phase I users presented in Chapter 7 of p, this Master Plan. Also the cost of chlorination at Shadowridge was not used since the L alternatives presented here propose to ultimately serve the Phase I users via a new distribution line. For this Master Plan, it is assumed that the Phase I facilities would be PI expanded after 5 years of operation. To account for the offset planning periods, new y salvage values were calculated for the Phase I facilities. Also, since some of the Phase I facilities would have a useful life of 20 years, replacement costs would be incurred in *» year 15 of the planning period for the alternatives presented here. Taking these factors to into consideration in addition to the Phase I O&M costs, the annualized cost to continue to supply reclaimed water to those markets served by Phase I facilities would be ^ $642,095 per year. Adding this annual cost to the annual project costs presented in lh» Table 9-9, and dividing by the total quantity of reclaimed water distributed results in the unit costs for the alternatives presented at the bottom of the table. to mm I 9-15 CHAPTER 10 RECOMMENDED PROJECT 10.1 RECOMMENDED PLAN PHASING Previous chapters have described the background and development of reclaimed water systems and have identified Alternative 1 to be the recommended project. This Chapter presents a description of the recommended plan and associated costs. As should be expected, re-evaluation of each aspect of the plan during detail design may produce some features that depart from those described in this Chapter. The physical components of the recommended plan include the tertiary treatment facilities in the vicinity of the Encina WPCF, a new storage tank, the existing Mahr Reservoir, a reclaimed water distribution pump station, the Mahr Reservoir, the distribution pipeline system, and all appurtenances necessary for a complete reclaimed water system to serve the study area. Appropriately 14 MG of storage will be required at the Mahr Reservoir; this represents about 26 percent of the 54 MG capacity. As previously stated, the facilities proposed for this study expand upon the Phase I facilities described in the Encina Basin Facilities Report by John S. Murk Engineers, Inc. The recommended project has been divided into five phases as described in this section and presented in Figures 10-1 through 10-5. Appendix G contains a list of pipelines by the identification numbers shown on the figures which includes pipeline diameter, pipeline lengths, and markets served. Table 10-1 lists the amount of reclaimed water used in each phase. 10.1.1 Phase I Phase I facilities are presented in Figure 10-1. The sources of supply for Phase I are the Meadowlark WRF and Gafner WTP, and the proposed users are Aviara Development, La Costa Hotel and Spa, CALTRANS, Frazee Flowers, and Ukegawa Farms. Reclaimed water will be transported to the users' sites via the existing failsafe pipeline systems, and stored on-site for distribution to the users' irrigation systems. The combined reclaimed water production capacity of the Meadowlark WRF and the Gafner WTP is 2,464 acre-feet per year (AF/YR) or 2.2 mgd (2.75 total treatment capacity less 20 percent to account for wasted solids). The annual demand based on the market research presented in Chapter 7 is 2,338 AF/YR. The projected peak demand is 4.6 mgd which exceeds the combined capacity of the Meadowlark and Gafner plants. The user demand will be met by a combination of reclaimed water and potable water to meet peak summer demands. 10-1 2500 5000 FT.

Phase II facilities would serve several markets in the southwestern part of the City and the area just north of the Palomar Airport Road and El Camino Real intersection. A portion the 20-inch abandoned line in El Camino Real would be connected to the distribution system. The Mahr Reservoir would begin to provide operational storage for the distribution system. The reclaimed water demand would increase to 4,240 AF/YR with a peak demand of 6.9 mgd. L 10.1.3 Phase III f A large number of markets in the northern part of the study area will be served when fci Phase III facilities become operational since the backbone of the northern portion of the system would be constructed. A 24-inch pipeline will be constructed along Alga Road F which will provide reclaimed water service to several markets. The facilities constructed • for Phase III will deliver an additional 2,600 AF/YR. During Phase III, both the tertiary treatment facility and reclaimed water distribution pump station would be expanded. ^P m 10.1.4 Phase IV IP^ As shown in Figure 10-4, four branches of the pipeline network would be added in Phase IV, adding markets in the southwest, southeast and north sections of the study area. »» The majority of the new markets served will be residential markets. Phase IV would to include the expansion of the tertiary treatment facilities and the distribution pump station to a peak capacity of 15.9 mgd. The total reclaimed water use during Phase IV will be "» 8,590 AF/YR. 10.1.5 Phase V fr" During Phase V, the distribution system to serve the higher elevations would be constructed which would include a pump station at the Mahr Reservoir, a new reservoir, L and a distribution system. The new reservoir will be constructed in the currently undeveloped area referred to as La Costa Northeast. In Phase V, the remaining markets p would be added to the system. The tertiary treatment facilities and the distribution pump |l station would be expanded to the ultimate capacity of the system. The ultimate system would serve 11,480 AF/YR of reclaimed water, with a peak demand of 21.4 mgd. 10.2 RECOMMENDED PROJECT COSTS E The projected costs for each of the five phases of the recommended project are presented in Table 10.-1. The table shows the expected date of operation of each phase, the total capital and operational costs, and the amount of reclaimed water • projected to be used. A further breakdown of these costs, including the cost of the 10-7 C tertiary treatment facilities, pump stations, reservoirs, and distribution pipelines, is presented in Appendix G. The impact of the construction and operation of the proposed reclaimed water facilities would result in an increase in the total debt service and operation and maintenance costs to the CMWD. As shown in Table 10-1, the operation and maintenance costs of would increase from $668,000 for the Phase I facilities, to $2,569,000, when the Phase V C C E C E E c E C E 1 1 1 1 1 Taciimes are in operatic Capital Costs Design Construction including Services Land Total Capital Costs 2 O&M Increase3 Total O&M2 Reclaimed Water Use Annual Use, AF/YR Peak Day, mgd )n.

It is unlikely also that sufficient cash flow is currently being generated to operate and maintain the proposed facilities. Thus, several methods for generating necessary capital for construction and revenue for O&M will be required. The following sections describe California's public facilities financing methods which could be used to construct wastewater treatment/water reclamation plant and appurtenant reclaimed water storage and distribution facilities. Some methods have more direct applicability to the proposed project than others, but a more in-depth financial analysis will be required during the implementation phase of the project to determine which method or combination of methods is most suitable for financing the project. That financial analysis will closely examine the existing and future fee structure for the individual agencies participating in the program. In addition to California's traditional financing methods described, this Chapter describes the local and regional financing methods unique to water reclamation projects. These include programs sponsored by the San Diego County Water Authority (CWA), Metropolitan Water District of Southern California (MWD), and the State of California. This Chapter also presents an overview of reclaimed water pricing from the author's perspective and based on local and regional methodology developed to date. This overview with specific recommendations for the study should be considered a starting point for the City to build a solid defensible, but flexible reclaimed water pricing program for the future. The final sections analyze the revenues, expenditures, and capital costs of the construction and operation of the recommended project throughout the planning period with pro forma statements of the financial analyses. 11.2 PROJECT FINANCING ALTERNATIVES 11.2.1 Capital Financing Alternatives The following sections give a brief overview of reliable capital facility financing methods successfully used in California and some organizational structures for the agencies involved as they relate to project financing. 11-1 m m 11.2.1.1 Mello-Roos Community Facilities Act of 1982 m On January 2,1983, the "Mello-Roos Community Facilities Act of 1982" became effective. *• This statute authorizes formation of community facilities districts which are authorized to provide certain additional public services or facilities to be financed through elector- approved special taxes. The code enactment for the Mello-Roos Act is found in the ^ Government Code commencing with Section 53311 (Chapter 2.5 to Part 1 of Division 2, p. Title 5 of said Government Code.) to A Mello-Roos Community Facilities District is formed either by a written request signed p by two members of the legislative body or a petition submitted by not less than 10 to percent of the registered voters within the proposed district boundary. The services which a community facilities district may provide are defined as additional services p performed by employees to provide police protection and/or fire protection and it suppression services (including operation, maintenance and repair activities) to the extent that they are in addition to those provided in the territory before the district was • created.m Facilities which can be provided under the Mello-Roos Act include the purchase, p construction, expansion or rehabilitation of the following: 1) Local park, recreation or parkway facilities. 'L 2) Elementary and secondary school sites and structures. 3) Libraries. m 4) Any other governmental facilities the legislative body is authorized to construct, own, m or operate. m The question of a special tax levy must be submitted to qualified electors within the to district. If fewer than 12 registered voters reside within the proposed district, the vote is by landowners voting one vote per acre or portion thereof. If long term bonded m indebtedness is required, a resolution and public hearing is also required on the •i necessity to incur the debt. Bonds are secured by the voted special taxes within the community facilities district and this special tax is levied in the same manner as general ff taxes for the legislative body with the funds paid to the community facilities district. 11.2.1.2 Special Benefit Assessment District Special assessment financing is applicable when the value or benefit of an improvement E can be assigned to a particular property. Assessments are levied in specific amounts against each individual property on the basis of the benefit each receives. Special assessments may be used for both publicly dedicated on-site and off-site improvements. it• The most commonly used assessment acts are the Improvement Act of 1911 (California Streets and Highway Code Sections 5000 et. seq.), the Municipal Improvement Act of • 1913 (California Streets and Highway Code Sections 8500 et. seq.). f* 11-2m m 1913 and 1915 Acts p* 1915 Bonds are typically issued in conjunction with the 1913 Improvement Act. «• Virtually any capital improvement can be financed. Assessments are levied and bonds are issued PRIOR to the actual construction of public improvements. "* Bonded indebtedness is the collective responsibility of all parcels within the *• assessment district. The bond issue is a lien AGAINST ALL PROPERTIES, although each parcel does have a specific assessment against it. Bonds are not L issued to represent individual parcels but are pooled in marketable denominations. Bonds are tax-exempt and not usually rated. P•y The 1915 Bond Act offers some flexibility in funding high initial capital costs. Bonds can be issued in series to parallel the cash loan needs of major projects pi that are staged over time. Time-phasing of bond issues not only reduces interest m costs, but also affords more time for development to occur. As development progresses, property values increase and the funding potential of assessment m bonds rises. Bonds are tax- exempt, do not require voter approval, and can be If sold at a discount which increases the effective interest rate of yield. P 11.2.1.3 Lease Purchasei The lease-purchase arrangement allows a city to extend payment of capital purchases r over time without a vote of the electorate. Equipment is purchased by the city and * financed by an institution which retains title to the property. The city "leases" the m purchase, making equal annual payments to the institution. Title to the capital L expenditure reverts to the city upon final payment. p 11.2.1.4 Joint Power Authority I A Joint Power Authority (JPA) is not in itself a financing mechanism but rather a means to I establish a third party for financing and administration of a project. Where two or more agencies are involved in a public facility or service, a JPA may be formed including representatives from each agency involved in the agreement. : i 11.2.1.5 Nonprofit Corporation (Public Facilities Corporation) Like the JPA, the nonprofit corporation (NPC) is not in itself a financing mechanism, but rather a tool for issuing debt. The traditional purpose of a nonprofit corporation is to issue revenue or lease revenue bonds secured by a pledge of revenues due under a lease of the project to a public entity (usually a city, county, school district, or redevelopment agency). It is necessary for the governing body of the public entity to cause the formation of the nonprofit corporation, which is incorporated pursuant to Part 1, commencing with Section 9000, of Division 2 of Title 1 of the Corporation Code. This corporation must 11-3 fW m m m also qualify as a charitable corporation under Section 501 (c) (3) of the Internal Revenue Code of 1954, as amended. Revenue Ruling 63-20 of the Internal Revenue Service *• provides further clarification on how public entities may use nonprofit corporations to te finance public facilities. *" This financing technique is used primarily for large public facility construction projects. *• The nonprofit corporation agrees to construct the project and to lease back the site and the project to the public entity (City) for a certain annual rental. The corporation finances *" the project by issuance of bonds secured by the pledge of the rental revenues. Once 1111 the bonds are paid in full, the nonprofit corporation is disbanded and the project and site ^ revert to the city. "* Security on nonprofit corporation financing is provided by the lease agreement, *. insurance on the facility, a reserve fund equal to maximum annual debt service but not ^ more that 15 percent of the bonds issued, and revenues pledged for repayment. Pledged revenues may include project revenues, tax increments, and the revenues and m reserves of the general fund. m NPCs have been used extensively in California to assist public entities in financing *• facilities. All leases must be approved by ordinance which is subject to referendum It under California law. If a sufficient number of voters petition to put the matter on the ballot and 50 percent of those voting oppose approval of the lease, all proceedings must p be terminated. An offering on nonprofit corporation bonds in an amount of $500,000 or * more must be bid at a public competitive sale under California law. *" 11.2.1.6 Revenue Bondsto p Revenue Bonds are used for debts incurred in the purchase or construction of specific |0 property which are to be paid solely from income generated by use of that property. Revenue bonds are considered self-liquidating and will generally not constitute a debt of p the issuer. m The Sewer Revenue Bond Act of 1933 contained in Chapter 5, Section 4950 et.seq., Part fP 3, Division 5 of the Health and Safety Code allows for financing of sewage projects. V These issues do not need voter approval unless 15 percent of the property owners or registered voters petition an election. IP ^ The Revenue Act of 1941, Chapter 6, Section 54300 et.seq., Part 1, Division 2, Title 5 of the Government Code may be used to finance water systems, garbage or refuse jT collection and disposal facilities, sewage systems, parking facilities, and various other public projects. IP H Issuers of revenue bonds may be cities, counties, redevelopment agencies, parking authorities, joint powers authorities or nonprofit corporations as specified in the m respective revenue acts. Except for the use of the Sewer Revenue Act of 1933 majority b m 11-4 * in voter approval is required to authorize the specific purpose and size of an issue. Revenue bonds have no legal limit on the amount of bonds issued and there is no "* obligation on the part of the general fund either to raise taxes or operate and maintain «• the facilities. *"* 11.2.1.7 Lease Revenue Bonds m A form of debt financing that has evolved over the past several decades is known as "lease-revenue bond" financing. Simply stated, lease revenue bond financing is a 111 process wherein one entity finances a public facility with revenue bonds, the revenue for p, which is derived from a long term lease agreement with a public agency. The entity m issuing the revenue bonds may be a non-profit corporation formed for that purpose or it could be a joint authority created by two or more local agencies for the purpose of «• finding the construction of the facilities. • Depending on which form the entity (NPC or JPA) is used to finance the facility, the ** procedure will differ slightly. In the case of a NPC, the Board of Supervisors would form fci the corporation by resolution and could appoint itself as board of directors of the corporation. p * Using the JPA as the financing entity requires that two or more public agencies adopt resolutions and/or ordinances authorizing the joint exercise of powers common to the " agencies by the joint powers authority. The governing body of the joint authority may consist of members of the governing bodies of the parent agencies or those agencies p may appoint a separate board. The JPA may issue bonds for the construction of certain |f facilities. The benefiting public agency will enter into a lease agreement with the JPA for the facility that is being financed. The lease agreement is subject to referendum. The m lease provides the security on which the bonds are issued. The debt obligation is not a jfg "general obligation" of the parent public agencies, but is rather a specific obligation against the revenue pledged for the lease payments of the lessee agency. m •I Lease-revenue bond financing can be used for a wide variety of public facilities. In 1985 the legislature enacted Senate Bill 17 (Marks) which greatly expanded the types of B facilities that joint powers agencies may finance and include a Water Reclamation Facility * (WRF). 1 A key consideration in the case of either a JPA or NPC is what source of revenue will be used by the leasing agency to provide for the lease payments. In some instances the p revenue might be derived from a combination of development fees and increments of H taxes to be used to fund the lease payments. In either case the leasing entity will need to make a specific commitment of revenue before the creation of the debt obligation in §order to provide the necessary assurances to the potential purchasers of the bonds that will make the bonds marketable at competitive rates. m H * 11-5 m 11.2.1.8 Certificates of Participation m This financing technique provides long term financing through a lease (with an option to b purchase or a conditional sale agreement) that does not constitute indebtedness under the State constitutional debt limit and does not require voter approval. This method is ** being used for long term financing of major projects, such as administration buildings,m public safety facilities, court houses, parking garages, and public works facilities. p 11.2.1.9 Special Obligation Bonds JP, In 1985 the California Legislature authorized the issuance of special obligation bonds for to the financing of capital improvements. The legislation authorizes cities and counties, but not special districts, to issue limited obligation bonds secured by a specific amount of m revenue received from any source, including property or sales tax, to acquire, install, m construct or improve any or all public works or improvements which the local agency is otherwise authorized to undertake. The issuance of the bonds for such purposes * requires a majority vote of the electorate of the issuing city or county. m To issue limited obligation bonds, a city or county must first determine that facilities will ** be constructed or improved with the proceeds of the bonds. Once determined, the * governing body adopts a resolution which designates the revenue source(s) and amounts that will be pledged to pay the debt service on the bonds. The question of * whether the bonds should be issued is then put to a vote of the electorate at the next •* general election. If the question receives a majority vote the bonds are issued and _ construction of the facility is undertaken. t^W t^M 11.2.2 Special Reclamation Financing Methods m y 11.2.2.1 CWA Water Reclamation Technical Assistance Program P) On May 19,1988, to further promote the development of water reclamation in San Diego iM County, the CWA Board of Directors authorized funding for the Water Reclamation Technical Assistance Program. The intent of the program was to encourage water S reclamation facilities planning, feasibility investigations and preliminary engineering studies. As authorized, the program provided funding for water reclamation project documents, on a 50:50 cost sharing basis, with the maximum contribution set at $50,000 for any given study. The fiscal year 1988-1989 budget for the program was limited to $300,000.3 1 The fiscal year 1989-1990 Water Reclamation Financial Assistance Program provides the same support to the development of water reclamation projects as the original program, p but includes a more structured application procedure and a budget of $500,000. The H new program also provides funding for research projects related to the development of water reclamation. Other aspects of the program remain the same and are listed below: mi P 11-6m m m • Support proponent on a 50:50 cost sharing basis. ** • Maximum CWA funding contribution for a given study to be set at $50,000.m • If the CWA becomes the lead agency, the proponent(s) shall deposit the amount of m their cost sharing with the CWA at commencement of the study.In m • If the CWA is not the lead agency, the CWA's share shall be made available on a matching basis (up to $50,000), as needed by the proponents). am • If the study results in implementation with CWA and funding from other sources, the to CWA shall be reimbursed such amounts as may be permitted from the funding source, not to exceed the amount contributed by CWA to the study plus interest •* calculated at the CWA's average interest earnings rate for the pertinent period. M In order to evaluate process requests for the Financial Assistance funding in a fair and m equitable manner to all project proponents, a detailed application and review process fb was established. The application process consists of two application periods in the summer and winter. The first period had a deadline of August 31,1989. The second m application period will occur during the month of January 1990. Once the deadline has 11 passed, a Financial Assistance Program Review Committee consisting of Water Authority Reclamation Advisory Committee (WARAC) members, review the applications and L formulate a recommendation to WARAC on each application. A priority list will be formulated based on how each applicant satisfies certain criteria. II To assure that all the funding available from the CWA for fiscal year 1989-1990 was not allocated during the summer application period, only half the budgeted amount was m available to the applicants. Any money not allocated will be available at the winter II application period. If all the money designated for the summer application is allocated, applicants not approved for funding will be encouraged to resubmit during the winter fP application period. If an applicant chooses to proceed with a study and then requests Hi funding at the winter application period, the review committee will consider the request along with other applicants, with no guarantee that they will receive funding. M'""11.2.2.2 Proposed San Diego County Water Authority Revenue Enhancement Programn The Water Reclamation Revenue Enhancement Program was initiated by the SDCWA in p June 1990 to assist local agencies in developing water reclamation projects. The H SDCWA is interested in developing local water sources to relieve dependence on imported water supplies. The adopted program includes the following stipulations: I • SDCWA contributions will be based on the actual financial need of a project after detailed consideration has been given to all other funding sources including • Metropolitan Water District of Southern California (MWD) contributions, reclaimed 11-7 m water sales, and costs attributable to sewage disposal. Financial need is defined when a project is not financially possible under normal conditions unless SDCWA *" provides financial assistance. m • A project requiring the SDCWA's financial assistance will be eligible for a financial '"" contribution of up to $100 per AF, subject to periodic review by the SDCWA Board of *" Directors. P«• The project lead agency must be able to demonstrate an ability to produce a new water supply that replaces a demand on the SDCWA. IP ta • Any prior obligations for reimbursement of the SDCWA funds distributed through the SDCWA Technical Assistance Program will be deducted from approved *•« contributions. IK • As an alternative to annual contributions, the SDCWA can make a one-time capital m contribution which will be financially equivalent to the estimated annual contributions. • Should the project lead agency be unable to meet the contractual commitments for supply development, all or part of the funding contribution shall be returned to the • SDCWA. tt • The SDCWA will tailor its financial contribution to a project by varying the term of ff the agreement. The maximum term would be twenty years. In cases where the project becomes financially self-sufficient in less than twenty years, the term of _ participation will be adjusted to the break-even year.B 1 1 1 .2.2.3 Metropolitan Water District Local Projects Program (LPP) SPSBH Under the MWD Local Projects Program, qualifying reclamation projects are eligible for a subsidy equivalent to MWD's avoided State Water Project pumping costs. The B reclamation program must be a "Local Project" which is defined as a project under which a new local water supply is developed by MWD's member agency or subagency that receives municipal and industrial water from MWD. The new water supply must be used S in MWD's service area and will reduce MWD's cost to convey, treat, and distribute water. Recently, each AF of new local supply avoided the delivery of an AF of imported water at an estimated energy cost savings of $93 per AF. The program in the past allowed a B minimum payment of $75 per AF which was based on the average net demand of approximately 3,000 kilowatt-hour kWh per acre foot multiplied by the Department of __ Water Resources' (DWR) average sale price for surplus energy of $0.25/kWh. Currently, the LPP contribution by MWD to a water reclamation project is $154 per AF. • To qualify for funding, a project must meet the following qualifying criteria: • The project must deliver at least 100 AF/YR of new water within MWD's service p area and replace firm water demands on MWD's system, ? 11-8i pi • The project must require MWD's financial assistance to be economically viable to the project sponsor, • The project must be implementable under MWD's enabling Act and any other pertinent legal requirements, • The project must have a Facilities Plan completed to show project layout, staging, and cost. A marketing analysis must be completed for nonpotable projects, • The project must demonstrate that public health and regulatory permits are obtainable, • The project must comply with the provisions of the California Environmental Quality Act (CEQA) before MWD's Board of Directors can approve the project for inclusion in the LPP. If the project meets the qualifying criteria, a contract is negotiated with the following contracting principles: • The project will be constructed, owned, and operated by the sponsoring agency, • MWD will guarantee to purchase the project's new water yield at the unit rate equal to the sum of MWD's applicable water rate plus LPP contribution of $154 per AF, • The new water yield will be sold to MWD's member agency at the applicable water rate for resale to the project sponsor (if the member agency is not the sponsor), • The net effective payment by MWD will be the LPP Contribution. The LPP Contribution will be reviewed and may be adjusted by MWD's Board of Directors periodically. The maximum period between reviews is to be five years and the minimum three years. • All contracts will include a MWD member agency. • The term of the agreement will be up to 25 years. Since the SDCWA is the only local member agency of MWD, it must be a co-party to any agreement under this program with the OMWD. The LPP is not intended to provide a direct capital facilities funding mechanism. However, if any agency is unable to secure financing for its project, MWD will consider providing a capital contribution equivalent to MWD's estimated annual contributions. In such event, MWD would own the yield from the project and the project sponsor would be required to guarantee that the project would produce an appropriate amount of water for 11-9 IP m MWD. The LPP Contribution is important factor in conducting economic and financial feasibility studies for reclamation projects, often becoming the factor making a potential * reclamation project initially feasible.m 11.2.2.4 State Low-Interest Loan Funding *• In November 1988, two State of California bond issues for funding reclaimed water ^ projects with low-interest loans were passed by the States's voters, as follows: *" • Mello Bill, SB 997, Clean Water and Water Reclamation Bond Law of 1988, which will m provide $30 million for loans administered by the State Water Resources Control m Board (SWRCB). Office of Water Recycling, and *- • Costa Bill, AB 1715, Water Conservation Bond Law of 1988, which will provide $20 m million for water projects assistance, water conservation, and groundwater recharge for loans administered by the State Department of Water Resources (DWR). This «"» issue includes the funding of facilities to store and distribute reclaimed water, but not m to treat it. F* Because the loan program guidelines for the Water Conservation Bond Law of 1988 if have not yet been finalized, the following information will apply only to the SWRCB administered Clean Water and Water Reclamation Bond Law of 1988 (1988 Bond Law), * and the preceding Clean Water Bond Law of 1984 (1984 Bond Law). m The 1984 and 1988 Bond Laws are administered by the SWRCB. The purpose of the H programs is to develop cost-effective water reclamation projects which will augment water supplies. For the purposes of the SWRCB loan programs water reclamation is p defined as the process of treating wastewater to produce water for beneficial use, the |f storage and distribution of reclaimed water to the place of use, and the actual use of reclaimed water. The loan program is administered by the SWRCB's Office of Water «* Recycling. m Clean Water Bond Law of 1984pi H A Water Reclamation Account was established under 1984 Bond Law, which authorized up to $25 million for loans to municipalities to assist in the design and construction of B water reclamation projects. Repayments of principal and interest are returned to the * Water Reclamation Account to make additional loans. Also, the first $30 million in _ principal and interest repaid for loans for wastewater facilities from the Clean Water E Construction Grant Account, provided for the 1984 Bond Law, will be deposited in the Water Reclamation Account. RIf Loans for water reclamation projects could be for a period of up to 25 years at an interest rate equal to 50 percent of the rate paid by the State on the most recent sale of m state general obligation bonds. A moratorium on payments of principal and interest isa M 11-10 * not permitted. No single project received more than a $2 million loan from this program. Loans could cover any part of a project up to 100 percent design and construction costs. The Leucadia County Water District has .been approved to receive funds from the 1984 Bond law to upgrade the Forest R. Gafner reclamation plant to meet the most stringent Title 22 requirments. Clean Water and Water Reclamation Bond Law of 1988 Up to $30 million is available under the 1988 Bond Law for loans to local public agencies to aid in the design and construction of water reclamation projects. Local public agencies do not include state agencies, which are included in the 1984 Bond Law as part of "municipalities". Loan repayments from these funds do not become part of a revolving fund as is the case of the 1984 Bond Law. The objective of the 1988 Bond Law is to provide assistance to eligible water reclamation projects. Generally, available funds will be committed to projects for which facilities planning is complete, provided the project meets the loan program requirements and is ready to proceed. However, the SWRCB reserves the right to manage the program to achieve the best use of loan funds. For example, the SWCRB may reserve funds for projects deserving special consideration or offer partial loans to achieve the maximum use of available loan finds. Under present SWRCB policy, a maximum loan commitment of $5 million is established for an individual project. It is the obligation of all loan applicants to comply with the California Environmental Quality Act (CEQA). Separate guidelines have been issued to describe these H requirements. The State Board cannot authorize a loan until the CEQA process is complete. Any change in the project after completion of the CEQA process or after p concept approval by the State Board may result in the need to revise CEQA documents. I The reclamation loan program begins with the SWRCB distributing loan application •P* packages to interested agencies upon request. The completed applications, including M project planning documents, are submitted by the applicant for review. After determining that project planning is complete and all other application requirements have been met, fl SWRCB staff presents the project to its Board for approval of a loan commitment and • subsequent loan contract. B Once the project is designed, the SWRCB's Office of Water Recycling reviews and "• approves the plans and specifications, user contracts, construction financing plan, and revenue program. An approval to advertise is then issued to the applicant, and a loan • contract is drafted. When the applicant has awarded the construction contract, the loan contract is executed and a 100 percent loan payment may be requested. Loan p repayments from the applicant to the SWRCB must begin within two years after award of jy the construction contract. P« To further State support of reclamation projects funding Assembly Bill (AB) 1312 (Filante 11-11 ill and Bradley) is being proposed for the November 1990 election. AB 1312 as recently proposed would authorize the sale pf $200 million in State bond issues to finance S reclamation projects. However, because of the enormous value of State bond issues approved by the voters in June 1990, AB 1312's funding authorization has reportedly been trimmed to $50 million.p» ** 11.2.3 Alternative Revenue Sources Methods for obtaining additional revenue to be used to finance the proposed project 111 include increasing the connection fees for future development and increasing the sewer p, and/or service charges. It has been estimated that future development will occur at a .•m rate of 1,130 equivalent dwelling units (EDUs) per year until ultimate build-out, which is expected to occur about 2013. Currently, approximately 26,517 EDUs exist in the City of IP Carlsbad. The current charges and fees within the City of Carlsbad are as follows: P» m • Carlsbad Sewer District Sewer Service Charge: $7.30/EDU/month * Sewer Connection Fee:$1,250/EDUb • Leucadia County Water District P Sewer Service Charge: $13.45/EDU/month * Sewer Connection Fee:$2,600/EDU fc • Vallecitos Water District, Improvement District A Sewer Service Charge: $11.85/EDU/month *» Sewer Connection Fee:$2,400/EDU «•• Vallecitos Water District, Improvement Districts 1, 2, 5, and 6 <P Sewer Service Charge: $11.50/EDU/month m Sewer Connection Fee:$2,400/EDU f 11.3 RECLAIMED WATER PRICING The following discussion of reclaimed water pricing is based on the methodology P exercised by various local agencies in Southern California implementing successful ™ water reclamation programs, and on a literature review of the subject. Through interviews with personnel from these agencies it becomes clear that there is no standard E methodology being conducted for reclaimed water pricing. Each agency has its own method that works for that situation. To prove this point, the following briefly describes «P the methods used at these agencies. These methods are summarized in Table 11-1 at m the end of this section. mi m 11-12 it • m 11.3.1 Irvine Ranch Water District m The Irvine Ranch Water District (IRWD) began planning its highly successful reclaimed m water system in the early 1960's and has maintained a separate reclaimed water distribution system since the mid-1960's. As demonstrated by a 1987 paper titled, *" "Water Reclamation - Is It Cost Effective? Irvine Ranch Water District - A Case Study," the 111 IRWD has given the cost and pricing of reclaimed water a lot of analysis. The paper m documents the IRWD's actual costs, in dollars per AF for tertiary treatment and ^ distribution of reclaimed water. Adding a factor for capital replacement reserve, the IRWD found at that time that the cost of producing and distributing reclaimed water was ~ $303 per AF. This cost compared well with the IRWD's calculation for providing m additional potable water supply, which amounted to $449 per AF, and does not include the cost to develop and deliver additional water supplies from northern California. m In the past the IRWD conducted detailed economic analyses for each new prospective reclaimed water market area to determine if reclaimed service was economically viable.m The price of reclaimed water was then set by this analysis, generally in the range of 85 * percent of potable. Some areas of IRWD were excluded from reclaimed water service because of high pumping costs. The IRWD now reportedly recognizes the absolute P need to develop alternative water supply sources for the region, and is making it "* mandatory to use reclaimed water for certain major irrigation markets throughout its boundary. m At present, the policy is to price reclaimed water at about 80 percent of potable water p, throughout the IRWD. Potable water is sold for about $231 per AF and reclaimed water H is, therefore, sold for about $184 per AF. Most major capital facilities for the reclaimed system are paid for with general obligation bonds. Thus, the cost of major capital P> facilities for reclaimed water are paid separately with property taxes. In addition, IRWD M charges a monthly meter fee to both potable and reclaimed water users varying from $4 for a 3/4-inch meter to $246 for a 4-inch turbo-meter. Both reclamation system costs * and revenues are fc allocated to the sewer side of the ledger at the IRWD rather than the water side. R One interesting program for the funding of the user system retrofitting of irrigation * equipment is exercised by the IRWD. IRWD provides the user a loan for such retrofitting. The user then must pay an abnormally higher water price for the reclaimed water until II the loan principal and interest is paid off by the accumulated price differential. p 11.3.2 Santa Margarita Water District m The Santa Margarita Water District (SMWD) in Orange County, California has an active, m on-going reclamation program that began in the late 1970's. Serving about 2,400 AF/YR JM of reclaimed water today from a 3 mgd tertiary treatment plant, the SMWD is proposing to produce up to 25 mgd of reclaimed water ultimately. 11-13 Hi The SMWD has eight separate improvement districts for water service, only one which is allowed to serve reclaimed water by the San Diego RWQCB (without demineralization). *" In that one improvement district the SMWD irrigates about 800 acres with reclaimed ^ water equivalent to about 2,400 AF/YR . The SMWD has plans to irrigate up to 1,300 ^ acres in that same improvement district. With an approved Basin Plan amendment from the RWQCB SMWD will reportedly some day have markets to use up to 25 mgd (77 AF "" per day) of reclaimed water. Because reclaimed water can only be served to customers in one improvement district, ** the SMWD's policy is to sell reclaimed water at the same price as its potable water •» (about $500 per AF). The SMWD officials reportedly believe it unfair to serve reclaimed m irrigation to select customers in one improvement district at a price discount, when other irrigation water customers are paying full price. 4M to Most of the reclaimed water distribution system built within the SMWD is built in newly developing areas. Thus, no program for assisting in the retrofitting of existing irrigation *" systems is employed by the SMWD. Major distribution pipelines greater than 8 inches in *» diameter are constructed by the SMWD using bonds, capital improvement funds, and State loans. Developers are required to construct lesser-sized, on-site distribution and f* irrigation facilities. m 11.3.3 South Coast Water District m The South Coast Water District (SCWD) is another Orange County, California agency p with an active water reclamation program. Like many San Diego County water in purveyors, the SCWD is totally dependent on imported water supplies to serve its customers. Providing also sewage treatment capabilities to its customers, SCWD *• decided to enter the reclaimed water production and distribution business in the mid- IH 1980s when a major planned development was proposed in SCWD's service area which contained an 18-hole golf course and abundant community landscaping.n» *• The initial project delivered 860 AF/YR of tertiary treated reclaimed water through 50,000 feet of transmission and distribution mains, booster pump station, and 1.7 MG storage m reservoir. With eight initial users, including a golf course, parks, schoolyard, and green- ^ belt areas, the peak daily consumption was 2.6 mgd (8 AF per day). The system can ultimately provide 2,000 AF/YR of reclaimed water. JH The SCWD has developed a financial plan and revenue program whereby reclaimed p water is delivered at 80 percent of the imported water price to its customers. Thus, m reclaimed water is sold for about $340 per AF. SCWD also charges its reclaimed water customers a water conservation connection fee that varies according to the size and •» type of user. The fee is currently $404 per one-bedroom unit, $822 per two-bedroom m unit, $1336 per three-plus-bedroom unit, and varies for other residential and commercial/industrial user types. This fee is used to help defer the cost of State loansm used to construct the reclaimed facilities. All other project costs are repaid through Hi reclaimed water sales revenues. <p • 11-14 M 11.3.4 Las Virgenes Municipal Water District P The Las Virgenes Municipal Water District (LVMWD) is located in Ventura County, •* California, just north of Los Angeles. LVMWD has been distributing reclaimed water since the early 1970's. In 1986, LVMWD in cooperation with the Triunfo County f" Sanitation District (TCSD) completed a $9 million expansion of their joint reclaimed water *» distribution system funded by the MWD. The system is now delivering approximately 2,500 AF/YR of reclaimed water, which is planned to expand to 3,000 AF per year in the < next five years.i* ' p. The LVMWD now has an 8 mgd (24.5 AF per day) capacity tertiary treatment plant y producing the most restrictive Title 22 effluent for direct irrigation reuse and stream discharge. Special nutrient removal facilities are not required by the local RWQCB at this m time. The LVMWD is planning to ultimately expand its treatment capacity to 16 mgd. M Like the other agencies described in the chapter, the LVMWD has conducted detailed » cost and pricing analyses for its reclaimed water program. Also, like these other m agencies, LVMWD has settled on a percentage of potable water prices to market its reclaimed water. Reclaimed water is sold to users in the service area at 75 percent the m price of potable water, which peaks at about $450 per AF in the LVMWD. Thus, *•» reclaimed water is sold for about $338 per AF. m In addition, LVMWD charges new development a special water conservation connection m fee of $1,100 per new 3/4" potable water meter. This money is placed in a Water m Conservation Fund which is used to pay for up to 50 percent of on-site costs for m providing a dual-water system in new and existing developments. The Water Conservation Fund is also used to fund LVMWD-wide regional reclamation facilities, as *. well as water conservation fixtures, such as low-flush toilets. «•» LVMWD personnel report that users, including developers, are pleased with the 25 *" percent price discount for reclaimed water, which compensates for the cost of user- to constructed facility retro-fits and dual distribution system. The LVMWD is currently studying additional pricing and funding options, including using the Water Conservation *"* Fund to loan users the money to construct retro-fits, and charging extra for reclaimed «•» water until the loans are paid with the funds generated by the price differential. "" 11.3.5 Otay Water Districtm p, The Otay Water District (OWD) is located in the southern portion of San Diego County, , ' and is in fact the most southerly water purveyor serviced by the MWD via the CWA. The OWD has a 1.3 mgd capacity WRF which is expandable to 2.6 mgd. Because the WRF pi does not have acceptable reliability features and treatment redundancy to meet the H current most restrictive Title 22 Requirements, the WRF is currently treating only about 0.8 mgd. These deficiencies have been recently studied and the OWD will soon be p issuing a design contract to upgrade the WRF to provide 1.3 mgd of the highest quality P 11-15fe- p-i fc non-restricted Title 22 reclaimed water. The WRF will also then be conveniently expandable to 2.6 mgd in the future. I^PI i* For many years the OWD was required by the RWQCB to demineralize its effluent prior m to spray irrigation disposal. In May 1989, the SWRCB approved a Basin Plan j. amendment in a portion of the OWD's service area eliminating the need for further demineralization prior to spray irrigation in that area. The OWD is now, therefore, selling •M up to 0.6 mgd (1 .84 AF per day) of reclaimed water receiving secondary treatment for ^ construction use at the EastLake planned development in Chula Vista, California. OWD plans to sell 1 .3 mgd (4.0 AF per day) to EastLake in the future for irrigation of a golf m course, parks, and common greenbett areas. Ml The OWD has recently adopted an ordinance establishing a reclaimed water price equal «"» to its existing commercial potable water rate of $1.17 per hundred cubic feet ($510 per 1* AF). Because the OWD is at the end of the vast MWD system in Southern California and its present and future supplies are severely limited, reclaimed water is the only other * viable source available to future development. Thus, customers there should be * satisfied to pay this price for a reliable irrigation water source. !T The price for reclaimed water has no additional monthly meter charges to customers as * do the OWD's potable and irrigation water rates. The $510 per AF rate is currently being m charged to EastLake for the reclaimed water it uses for construction purposes, and will |i not go up in price (except with the OWD's regular commercial rate increases) when the reclaimed water quality is tertiary rather than secondary. I p m f"iin 11.3.6 County Sanitation Districts of Los Angeles County The Sanitation Districts of Los Angeles County (SDLAC) serve the sewage treatment needs of about four million people. In the urbanized areas of the Los Angeles Basin, SDLAC operates facilities known as the Joint Outfall System which includes five water reclamation plants with a treatment capacity of about 140 mgd. These plants provide the highest level of Title 22 treatment. Thus, the reclaimed water can be used for just about any type of non-potable demand. Excess reclaimed water is discharged to the San Gabriel River drainage basin for groundwater recharge and ocean disposal. In 1986, SDLAC reportedly provided 15.2 billion gallons (46,700 AF) of reclaimed water that was directly used, equivalent to the entire amount of water used by San Luis Obispo County (population of 187,000) at that time. During the fiscal year ending June 30, 1989, the SDLAC reportedly sold an average of 60 mgd (67,000 AF) to its customers. n-16 E p In Table 11-1 Summary of Reclaimed Water Pricing By Various Southern California Agencies mL I m m i I i Agency (California County) Irvine Ranch Water District (Orange) Santa Margarita Water District (Orange) South Coast Water District (Orange) Las Virgenes Municipal Water District (Ventura) Otay Water District (San Diego) Sanitation Districts of Los Angeles County (Los Angeles) City of Cerritos (Los Angeles) Existing Quantity Served (AF/YR) 8,000 2,400 1,200 2,500 670 67,000 1,500 Potable Price (perAF) $231 1 $497 $427 $450 $540 N/A $261 Reclaimed Price (perAF) $184 1 $497 $340 $338 $510 $20 3 $1744 Reclaimed/ Potable Price Ratio 80% 100% 80% 75% 95% N/A 67% MWD Rebate Yes Yes Yes 2 Applying No No IRWD builds all its major reclamation facilities with bonds, which are paid for with property taxes rather than user fees. Also, IRWD has a monthly meter charge for reclaimed and potable water ranging from $4/mo. for a 3/4" meter to $246/mo. for a 4" meter. 2 LVMWD received a $9 million loan from MWD to construct reclaimed water distribution facilities. SDLAC does not distribute its own reclaimed water normally, and considers the cost of treatment a sewage disposal cost. SDLAC provides land for each distributing agency to construct a pump station to receive and purvey reclaimed water purchased. 4 Cerritos received a $4.5 million state grant to construct a portion of its reclaimed water distribution facilities. Because tertiary treatment is needed by these five SDLAC plants for disposal purposes, the cost of reclaimed water production is not considered part of the sewerage service. SDLAC arbitrarily sells its reclaimed water to other agencies for a price equivalent to about one-fifth its WRFs' operation and maintenance costs, or about $15 to $20 per AF. SDLAC does have a few retail customers for its reclaimed water (one country club and some nurseries), but it charges the same low price. SDLAC is planning to renew its sales contracts with users in the future charging one-fifth MWD's price for treated, interruptible water, or about $30 per AF. 11-17 As an added benefit to its users, SDLAC provides free land for the construction of each E customer agency's distribution pump station at the WRF site. In addition, the SDLAC will provide pump station operations and associated trained personnel. The agency will have to pay the cost of constructing and operating the pump station, however. ^^ '* 11.3.6.1 City of Cerritos p*t The City of Cerritos (Cerritos) is one of the newer customers of the SDLAC and has recently started its own reclaimed water distribution and pricing systems. Cerritos last C year served about 1,500 AF of reclaimed water to various schools, parks, cemeteries, and other landscaped areas throughout its boundary. f> Cerritos originally established a price of 50 percent of potable water as its reclaimed || water rate, or about $131 per AF. Cerritos officials felt this price would provide the incentive necessary for users to join the system immediately. During the construction of P the $10 million distribution system, of which $4.5 million was provided by a State grant, it il was decided to have the same contractor install the reclaimed water tie-ins for each user. To justify this additional cost the price is now set at two-thirds of the city's potable 1 commodity rate. The price for reclaimed water served is now about $174 per AF. Cerritos has rights to up to 4,000 AF per year of reclaimed water from SDLAC, and ^ ultimately hopes to distribute 3,500 AF per year to its customers. r 11.4 FINANCIAL ANALYSIS h 11.4.1 Methodology **• ta The purpose of the financial analysis is to determine if the projected revenues from the sale of reclaimed water and other sources are sufficient to meet the debt service for r construction of the facilities and the annual operations and maintenance (O&M) costs. «M The financial analysis was performed twice; once by assuming revenue bonds would be used to fund the capital costs, and secondly by assuming a State low-interest loan would P be obtained for capital costs. The price of reclaimed water was set as a percentage of *"• the cost of potable water to arrive at a year end revenue balance that would not require ^ an increase in the water service charge or some other means to prevent a deficit. For the State loan the price for reclaimed water would be 91% of the cost of potable water; for m revenue bond funding, the cost of reclaimed water would be 109% of the cost of potable p water. The pro forma statements with State loan funding and with revenue funding are g presented in Table 11-2 and Table 11-3, respectively. Appendix J presents pro forma statements based on the scenarios of setting the price of reclaimed water equal to 75% m and 100% of the cost of potable water, and the amount of increase in the water service It charges that would be required to eliminate the deficits. 11-18 m 11.4.2 Costs «"" The capital costs and the annual O&M costs used in the financial analyses are those to presented in Chapter 10. These costs were increased at a rate of 3 percent per year to the year in which they would be incurred to account for inflation. The payments *" presented for reimbursement of existing facilities at the Meadowiark and Gafner • treatment plants in the Encina Basin Water Reclamation Project - Phase I Program Facilties Plan, by John S. Murk Engineers, Inc., are used in this analysis. The debt "" service was calculated for each phase for a loan amount equal to the construction costs * including services during construction plus the design costs compounded for one year ^ using the same interest rate as the permanent loan. A rate of 4.25 percent was used for the State low-interest loan analysis and a rate of 8.5 percent was used for the revenue *" bond analysis. 11.4.3 Revenues •• As stated, it was assumed that the source of funding for capital costs would be either a » State low-interest loan or revenue bonds. Also, it was assumed that the City of Carlsbad, would be eligible for the Metropolitan Water District (MWD) rebate. The ** current minimum MWD rebate is $75 per AF. Another source of revenue to offset the m production costs is the sale of reclaimed water. For these analyses, the price of reclaimed water was set at 100 percent of the retail price of potable water. This * percentage may change depending upon the reclaimed water pricing philosophy * adopted by the City. Both the MWD rebate and the price of reclaimed water were projected to increase at a rate of 6 percent. ^W ^m To offset the negative year-end balance during the initial critical years of the project, m revenues from increased water service charges were added to obtain a new year-end ^ balance. Rough estimates based on landuse designation and phasing obtained from the City of Carlsbad as well as water use projections previously made by other agencies • were used in the analyses. The amount of the increase per 100 cubic feet (CF) was |i varied until no negative year-end balances occurred. P 11.4.4 Financial Feasibility 1 Tables 11-2 and 11-3 demonstrate that the recommended plan is financially feasible with ff a calculated price reclaimed water without the need for additional revenues from • increased water service charges. As can be seen from the pro forma statements, the year-end balance is greatly affected by the percentage rate for financing. ^Wn If the price of reclaimed water were set at a lower rate, the resulting year end revenue p deficits could be eliminated by increasing the water service charge or sewer connection ii fees. I&&I pi 11-19 m An in-depth analysis to determine which financing mechanism is best suited for financing the project has not been done, but it appears that a calculated price for reclaimed water or increased water service charges would accommodate the revenue stream in the case of either a State low-interest loan or sale of revenue bonds. Also, in both analyses, a reserve is built up that could be used to construct replacement facilities. A more detailed study will be necessary to develop the organizational structure for financing and to refine the revenue stream necessary to support the debt service. The next steps should be taken concurrent with the design of the project which will also provide more detailed cost information.

Presented in Table 12-1 is the implementation schedule for Phase I of the recommended facilities. In addition to the design, construction, and operation milestones, the schedule also shows the key IP environmental and regulatory processing milestones. The implementation schedules for m the other phases, which are not presented, will appear very similar in format to the Phase I schedule. •» m As previously discussed, the CMWD will continue to be involved in initiating the implementation of the water reclamation recommendations in the master plan, which will m be adopted by the City of Carlsbad as the Board of Directors for the CMWD.m 12.2 ENVIRONMENTAL AND REGULATORYp *" 12.2.1 Environmental Impact Report ^ The California Environmental Quality Act (CEQA) requires that an environmental impact assessment form be prepared for the projects identified in this Master Plan. It is likely PI from this assessment that an environmental impact report (EIR) will be required for the l! construction of the treatment and distribution facilities described in this plan. The preparation, review, and certification of this document can be expected to take at least p nine months. in 12.2.2 Coastal Development Permitpi hi The construction of the reclaimed water treatment, storage, pumping, and distribution facilities located within the coastal zone will require a coastal development permit from r the California Coastal Commission. The tertiary facilities for the Encina WPCF, the * distribution pump station, a substantial portion of the distribution pipeline system, as well as three of the Phase I on-site pumping and storage facilities, are located within the '"L coastal zone.

The existing Waste Discharge Requirements for the Meadowlark WRF and the w Gafner WTP are expected to be adequate for the reclamation plan. The Encina EWPCF will require a new Report of Waste Discharge as application for modified Waste i* Discharge Requirements for the new reclaimed water treatment and distribution system. j^&i 12.2.4 Basin Plan Amendmentp **• The recommended project serves reclaimed water markets within Hydrographic Subarea 4.31 , a portion of which has current groundwater quality objectives and beneficial uses [* that restrict irrigation with reclaimed water unless it is demineralized. This area, which is •* east of El Camino Real and north of Highway 78 as shown in Figure 6-1 , has a total dissolved solids (TDS) limitation of 1 ,200 milligrams per liter. The use of reclaimed waterr objectives for TDS, chloride, nitrate, and boron. t in this area without demineralization will require a Basin Plan Amendment to eliminate the municipal and domestic supply beneficial use and to relax the groundwater quality The Basin Plan Amendment must be prepared by the CMWD and submitted to the r RWQCB for approval. The State Water Resource Control Board (SWRCB) and the i» Environmental Protection Agency (EPA) are responsible for reviewing the Basin Plan Amendment. The Basin Plan Amendment is equivalent to an EIR, and complies with l* CEQA requirements, with the RWQCB as the lead agency. KM 12.2.5 Inter-Agency Agreements **" Agreements will need to be reached between the suppliers of reclaimed water in the service area, the Encina JPA, the Vallecitos Water District, and the Leucadia County L Water District to utilize reclaimed water generated from the tertiary treatment facilities. The agreements would discuss the following items: P m • Responsibility for reclamation facility, IP • Responsibility for reclamation distribution system, including use of the Mahr Hi Reservoir, P • Quantity of reclaimed water provided, m • Description of institutional arrangements, If^m *- • Evaluatation of additional site acquisition for Encina and revise Master Plan for _ Encina, 12-4 1 • Quality of reclaimed water provided, and • Purchase price for reclaimed water. £Agreements will also be needed for the water purveyors in the service area for distribution of reclaimed water, the Vallecitos Water District, and the Olivenhain Municipal Water District, these agreements will focus on the distribution of reclaimed water within * the service area of the other water districts. _ 12.2.6 User AgreementsIPiUser participation and commitment is an important aspect in the implementation of the E plan. It has been proposed that the CMWD obtain letter of commitments from the proposed Phase I users. The letter of commitment would define the understanding between the user and the CMWD and would discuss the following: p* to • Responsibility for reclaimed water distribution system, •* • Quantity of reclaimed water to be provided, •H • Quality of reclaimed water to be provided, *" • Delivery schedule and pricing, and *•»• Point of connection to service. to p. After the commitment has been obtained, a contract between the user and the CMWD ta would be drafted. In lieu of user agreements, the CMWD may elect to adopt a mandatory reclaimed water use ordinance and issue user permits to individual users. *•» ta 12.3 FINANCING "" 12.3.1 Project Funding «• 12.3.1.1 State Loan Application *• In May 1990, the CMWD completed and submitted a loan application to the SWRCB low- ^ interest Loan Program. After the SWRCB staff approves the plan and makes preliminary eligibility determinations, the loan contract will be processed and executed by the SWRCB and the CMWD. Once design begins, the CMWD will submit design submittals m for SWRCB staff review. The SWRCB staff will make final eligibility determinations and fc authorize approval to advertise and award the construction contract. If SWRCB Loan Program funding is obtained, the funds will be released according to the disbursement *» schedule shown in Table 12-2. 12-5 m Table 12-2 w Loan Disbursement Schedule m Level of Construction Disbursement AmountPI to Award of construction contract Design costs and 60% of estimated construction p costsinConstruction 50 percent complete Payment based on 90% of estimated total eligible _ costs less the first disbursement • Construction and audit of project costs complete Payment to cover the remainder of the full loan share of all eligible costs 12.3.1.2 Bond Sales Programm m if funds are required from bonds sales, a sales program must be studied and developed. The bond sales program developed by financial experts will determine the type or types m of funding instruments that are most appropriate, the ratings of the bonds, and the P. amount to be funded. ttw 12.3.1.3 Other Financial Assistance ita, As discussed in detail in Chapter 11, other sources of funding for the proposed facilities may be available to the CMWD. To take advantage of these funds, the CMWD should "" apply for financial assistance from other agencies such as the CWA and the MWD. _ 12.3.2 Reclaimed Water Pricing Policy *• The CMWD will need to establish a pricing policy prior to distribution of reclaimed water. ^ Based on the financial analyses presented in Chapter 11, it is recommended that the 'L price of reclaimed water be set at or more than the retail price charged for potable water. Revenues from the sale of reclaimed water at that price will be sufficient to fund the debt p, service; pay operations and maintenance (O&M) costs; purchase reclaimed water from IP the Encina JPA, the VWD, and the LCWD; and provide a reserve for future expansions and replacement costs. m * 1.2.3.3 Project Financial Plan ** Once adopted, the CMWD will need to have an overall financial plan for each phase of to development for this Master Plan. Once project costs are refined in a project design report, a revenue program as part of the financial plan will establish in greater detail the ** adjustments to the CMWD water service fees necessary to fund the project. 12-6 ill m m m 12.4 RECLAIMED WATER pi II 12.4.1 Mandatory Use Ordinance m In May 1990, a mandatory reclaimed water use ordinance was adopted by the CMWD. M In accordance with State law that prohibits the use of potable water for irrigation when reclaimed water is available, the use ordinance will insure that as much reclaimed water *" reasonably possible will be used by the CMWD. 12.4.2 Rules and Regulations<• ^ The RWQCB requires the preparation of reclaimed water handling Rules and Regulations for a purveyor of reclaimed water and for the user of reclaimed water. The City of Carlsbad already has Rules and Regulations for the City which the user of reclaimed ** water can adopt and use. The City will be responsible for the enforcement of these P» regulations. These Rules and Regulations are included as Appendix H. "" 12.4.3 Reclaimed Water Use p* te The CMWD will be responsible for O&M for the reclaimed water system. General O&M of the facilities will be integrated with the CMWD's present O&M activities. m 12.4.4 Public Awareness Program *~ The CMWD should develop and execute a Public Awareness Program to inform the *• public on reclaimed water uses and benefits. By discussing a potential water crisis, the CMWD would highlight the need for reclaimed water and encourage its use. Methods of ** informing the public should include holding a public meeting to introduce this Master m Plan and newsletters with information about reclaimed water include in water bills. As a p more active measure, the CMWD could initiate public tours of water reclamation facilities, |l organize lectures in the classroom, and setup educational booths at community gatherings. p I 12.5 PLANNING, DESIGN, AND CONSTRUCTION «• 12.5.1 Reclaimed Water Markets m Since industrial use of reclaimed water may be sensitive to the quality of reclaimed water, " use-related water quality requirements should be assessed on an individual basis. ** Further investigation of water quality requirements should be conducted for both existing and proposed industries to determine weather reclaimed water is acceptable for that *" particular use. m As discussed in Chapter 7, the Batiquitos Lagoon Enhancement Project may require m <- 12-7 m 'm supplemental freshwater to maintain the proposed freshwater marsh impoundment. Further studies should be conducted to determine both the environmental impacts and <* the feasibility of using reclaimed water as the supplemental source of freshwater for the ii project. C i Any changes to the assumptions made in calculating the reclaimed water demands for potential users should be incorporated into this master plan. Of particular importance is the timing of water demands of both proposed projects and undeveloped land. Implementation of the Master Plan should include continual monitoring of the reclaimed water needs of potential users as development occurs and more accurate information becomes available. 12.5.2 Facility Planning The recommended project of this master plan requires that Title 22 facilities be located p near the Encina WPCF. There is an immediate need to initiate a siting study to evaluate In additional site acquisition adjacent the Encina or locate an appropriate and feasible site in the vicinity of the Encina WPCF. Also, immediate coordination is required for installing f" distribution pipelines as new roads are constructed since many of the proposed roads *"» are currently in design. When existing potable water lines are abandoned in the vicinity of future reclaimed water *" distribution lines, these potable water lines should be considered for possible reclaimed r water use. A review of potable water lines that are expected to be abandoned should be ! reviewed on an annual basis for each phase of the proposed reclaimed water distribution system. Some of the questions that should be answered in the review are the following: ^ 1. What is the design capacity, both in terms of flow and pressure of the potable water lines, and how does that compare to the required pressures and flows for "• the reclaimed water distribution system? I* 2. What is the expected economic life of the existing potable water line based on the '"" age of the pipe, the condition of the pipe, and the corrosion protection provided *» and the corrosion potential? 3. How many connections are there to other potable water piping that would require disconnection and separation? **> 4. Based on the economic life of the existing potable water line, what is the present worth value for the alternative of using the existing pipe in comparison to P» construction of a new reclaimed water distribution line? 12-8 m IP_ 12.5.3 Project Design and Construction IP Prior to any design of the proposed facilities in this master plan, a design standards Hi manual for the design and construction of reclaimed water distribution and storage facilities must be prepared. Preliminary design will include a project design report which •» will provide preliminary engineering for the proposed facilities and precise cost estimates ^ for the project financial plan. Final design will include the preparation of design plans and specifications. The design process will end with the bidding and award of the *" construction contract. The recommended project proposes that the ultimate system will • be constructed in five phases; however, detailed facilities planning and preliminary design of each phase may determine it more appropriate to increase or decrease the *" number of phases. m C m P 12-9 PI REFERENCES m Boyle Engineering Corporation and HYA Consulting Engineers.

On or before January 1 of each succeeding year, the operators of the next 150 solid waste disposal sites ranked on the list shall submit a solid waste water quality assessment test to the appropriate regional board for its examination pursu- ant to subdivision (d). (b) Before a solid waste water quality assessment test report may be submitted to the regional board, a registered geolo- gist, registered pursuant to Section 7850 of the Business and Professions Code, a certified engineering geologist, certified pursuant to Section 7842 of the Business and Professions Code, or a civil engineer registered pursuant to Section 6762 of the Business and Professions Code, who has at least five years' experience in groundwater hydrology, shall certify that the report contains all of the following information and any other information which the state board may, by regulation, require: (1) An analysis of the surface and groundwater on, under, and within one mile of the solid waste disposal site to provide a reliable indication whether there is any leakage of hazardous waste. (2) A ch lical characterization of the soil-pore liquid in those areas which are likely to be affected if the solid waste disposal site is leaking, as compared to geologically similar areas near the solid waste disposal site which have not been affected by leakage or waste discharge. (c) If the regional board determines that the information specified in para- graph (1) or (2) is not needed because other information demonstrates that haz- ardous wastes are migrating into the wa- ter, the regional board may waive the requirement to submit this information specified in paragraphs (1) and (2) of subdivision (b). The regional board shall also notify the State Department of Health Services, and shall take appropri- ate remedial action pursuant to Chapter 5 (commencing with Section 13300). (d) The regional board shall examine the report submitted pursuant to subdivi- sion (b) and determine whether the num- ber, location, and design of the wells and the soiling testing could detect any lea- chate buildup, leachate migration, or haz- ardous waste migration. If the regional board determines that the monitoring pro- gram could detect the leachate and haz- ardous waste, the regional board shall take the action specified in subdivision (e). If the regiona1 'roard determines that the monitoring p.\.fam was inadequate, the regional bobi.i shall require the solid waste disposal site to correct the monitor- ing program and resubmit the solid waste assessment test based upon the results from the corrected monitoring program. (e) The regional board shall examine the approved solid waste assessment test report and determine whether any hazard- ous waste migrated into the water. If the regional board determines that hazardous waste has migrated into the water, it shall notify the Stale Department of Health Services and the California Waste Man- agement Board and shall lake appropriate remedial action pursuant to Chapter 5 (commencing with Section 13300). (f) When a regional board revises the waste discharge requirements for a solid waste disposal site, the regional board shall consider the information provided in the solid waste assessment lest report for that solid waste disposal site.

In making such determination, the regional board shall consider all rele- vant evidence related to such discharge, in- cluding, but not limited to, those factors set forth in Section 13241. possible adverse impacts if such discharge is permitted, failure rates of any existing individual dis- posal systems whether due to inadequate design, construction or maintenance or un- suitable hydrogeologic conditions, evidence of any existing, prior, or potential contamination, existing and planned land use. dwelling density, historical population growth, and such other criteria as may be established pursuant to guidelines, regulations, or policies adopted by the state board. 13282. Where it appears that adequate protection of water quality, protection of beneficial uses of water, and prevention of nuisance, pollution, and contamination can be attained by appropriate design, location, sizing, spacing, construction, ind maintenance of individual disposal systems in lieu of elimination of discharges from such systems, and where an authorized public agency provides satisfactory assurance to the regional board that such systems will be appropriately designed, located, sized, spaced, constructed, and maintained, such discharges shall be per- mitted so long as such systems are ade- quately designed, located, sized, spaced, constructed, and maintained. 13283. In reviewing any determination that discharge of waste from existing or new individual disposal systems should not be permitted, the state board shall include a preliminary review of possible alter- natives necessary to achieve protection of water quality and present and future beneficial uses of water, and prevention of nuisance, pollution, and contamination, in- cluding, but not limited to, community collection and waste disposal systems which utilize subsurface disposal, and possible combinations of individual dis- posal systems, community collection and disposal systems which utilize subsurface disposal, and conventional treatment systems. 13284. The state board may adopt guidelines, regulations, or policies necessary to implement the provisions of this article. CHAPTER 5. ENFORCEMENT AND IMPLEMENTATION Article 1. Administrative Enforcement and Remedies by Regional Boards 13300. Whenever a regional board finds that a discharge of waste is taking place or threatening to take place that violates or will violate requirements prescribed by the regional board or the state board or that the waste collection, treatment, or disposal facilities of a discharger are approaching capacity, the board may require the dis- charger to submit for approval of the board, with such modifications as it may deem necessary, a detailed time schedule of specific actions the discharger shall take in order to correct or prevent a violation of requirements. 13301. When a regional board finds that a discharge of waste is taking place or threatening to take place within its region in violation of requirements or discharge prohibitions prescribed by the regional board, or the state board the board may issue an order to cease and desist and direct that those persons not complying with the requirements or discharge prohibitions (a) comply forthwith, (b) comply in accordance with a time schedule set by the board, or (c) in the event of a threatened violation, take appropriate remedial or preventive action. In the event of an existing or threatened violation of waste discharge requirements in the opera- tion of a community sewer system, cease and desist orders may restrict or prohibit the volume, type, or concentration of waste that might be added to such system by dischargers who did not discharge into the system prior to the issuance of the cease and desist order. Cease and desist orders may be issued directly by a board, after notice and hearing, or in accordance with the procedure set forth in Section 13302. 13301.1 The regional board shall render to persons against whom a cease and desist order is issued pursuant to Section 13301 all possible assistance in making available current information on successful and economical water quality control programs, as such information is developed by the stale board pursuant to Section 13167. and information and assistance in applying for federal and state funds necessary to comply with the cease and desist order. 13302. (a) Hearings for consideration of issuance of a cease and desist order may be conducted by hearing panels designated by the regional board, each panel to consist of three or more members of the board as it may specify. A member of the board may serve on more than one panel. (b) Due notice of the hearing shall be given to all affected persons. After the hearing, the panel shall report its proposed decision and order to the regional board and shall supply a copy to all parties who appeared at the hearing and requested a copy. Members of the panel are not dis- qualified from sitting as members of the board in deciding the matter. The board, after making such independent review of the record and taking such additional evidence as may be necessary, may adopt, which or without revision, the proposed decision and order of the panel. 13303. Cease and desist orders of the board shall become effective and final upon issuance thereof. Copies shall be served forthwith by personal service or by registered mail upon the person being charged with the violation of the re- quirements and upon other affected per- sons who appeared at the hearing and re- quested a copy. 13304. (a) Any person who has dis- charged or discharges waste into the wa- ters of this stale in violation of any waste discharge requirement or other order or prohibition issued b\ a regional board or the state board, or who has caused or permitted, causes or permits, or threatens lo cause or permit any waste to be dis- charged or deposited where it is. or prob- ably will be. discharged into the waters of the state and creates, or threatens to cre- ate, a condition of pollution or nuisance, shall upon order of the regional board clean up such waste or abate the effects thereof or. in the case of threatened pollu- tion or nuisance, take other necessary re- medial action. Upon failure of any person to comply with such cleanup or abatement order, the Attorney General, at the re- quest of the board, shall petition the supe- rior court for that county for the issuance of an injunction requiring such person to comply therewith. In any such suit, the court shall have jurisdiction to grant a prohibitory or mandatory injunction, ei- ther preliminary or permanent as the facts mav warrant. M ID m Environment Reporter CALIFORNIA PORTER—COLOGNE ACT S-11 721:0113 n IP pi m (b) The regional board may expend available moneys to perform any cleanup, abatement, or remedial work required un- der the circumstances set forth in subdivi- sion (a) which in its judgment is required by the magnitude of endeavor or urgency of prompt action needed to prevent sub- stantial pollution, nuisance, or injury to any waters of the state. Such action may be taken in default of, or in addition to, remedial work by the waste discharger or other persons, and regardless of whether injunctive relief is being sought. The regional board may perform the work itself, or by or in cooperation with any other governmental agency and may use rented tools or equipment, either with operators furnished or unoperated. Notwithstanding any other provisions of law, the regional board may enter into oral contacts for such work, and the contracts, whether written or oral, may include provisions for equipment rental and in ad- dition the funishing of labor and materials necessary to accomplish the work. Such contracts shall be exempt from approval by the Department of General Services pursuant to the provisions of Section 14780 of the Government Code. (c) If such waste is cleaned up, the effects thereof abated, or, in the case of threatened poi.ution or nuisance, other necessary remedial action is taken by any governmental agency, the person or per- sons who discharged the waste, discharges the waste, or threatened to cause or permit or permit the discharge of the waste, with- in the meaning of subdivision (a), shall be liable to that governmental agency 10 the extent of the reasonable costs actually in- curred in cleaning up such waste, abating the effects thereof, or taking other remedi- al action. The amount of such costs shall be recoverable in a civil action by, and paid to, such governmental agency and the state board to the extent of the tatter's contribution to the cleanup costs from the State Water Pollution Cleanup and Abate- ment Account of other available funds. (d) If, despite reasonable effort by the regional board to identify the person re- sponsible for the discharge of waste or the condition of pollution or nuisance, such person is not identified at the time cleanup, abatement, or remedial work must be performed, the regional board shall not be required to issue an order under this section. (e) "Threaten," for purposes of this sec- tion, means a condition creating a substan- tial probability of harm, when the prob- ability and potential extent of harm make it reasonably necessary to take immediate action to prevent, reduce, or mitigate dam- ages to persons, property, or natural resources. (f) This section does not impose an, new liability for acts occurring before Jan uary 1, 1981, if the acts were not in violation of existing laws or regulations at the time they occurred. 13305. (a) Upon determining that a condition of pollution or nuisance exists which has resulted from a nonoperating industrial or business location within its region, a regional board may cause notice of such condition to be posted upon the property in question. The notice shall state that such condition constitutes either a condition of pollution or nuisance which must be abated by correction of such con- dition, otherwise it will be corrected by the city, county, other public agency, or regional board at the property owner's ex- pense. Such notice shall further state that all property owners having any objections to the proposed correction of such condi- tion may attend a hearing to be held by the board at a time not less than 10 days from the posting of the notice. (b) Notice of the hearing prescribed in this section shall be given in the county where the property is located pursuant to Section 6061 of the Government Code. (c) In addition to posting and publica- tion, notice as required in this section shall be mailed to the property owners as their names and addresses appear from the last equalized assessment roll. (d) At the time stated in the notices, the board shall hear and consider all objec- tions or protests, if any, to the proposed correction of the condition, and may con- tinue the hearing from time to time. (e) After final action is taken by '-;•• board on the disposition of any protests or objections, or in case no protests or objec- tions are received, the board shall request the city, county, or other public agency in which the conditions of pollution or the nuisance exists to abate it. In the event that such city, county, or other public agency does not abate such condition within a reasonable time the board shall cause the condition to be abated. It may proceed by force account, contract or other agreement or any other method deemed most ex- pedient by the board, and shall apply to the state board for the necessary funds. (0 The owner of the property on which the condition exists, or is created, is liable for all reasonable costs incurred by the board or any city, county, or public agency in abating in condition. The amount of the cost for abating the condition upon the property in question shall constitute a lien upon the property so posted upon the recordation of a notice of lien, particularly describing the property on which the con- dition was abated and the amount of such ., in the office of the county recorder of .; county in which the property is located. Unon such recordation, the lien shall have the same force, effect, and priority as if it h: ] been a judgment lien imposed upon n . property which was not exempt from execution, except that it shall attach only to the property so posted and described in such notice of lien, and shall continue for 10 years from the time of the recording of such notice unless sooner released or otherwise discharged. Such lien may be foreclosed by an action brought by the ci- ty, county, other public agency, or state board, on behalf of the regional board, for a money judgment. Money recovered by a judgment in favor of the state board shall be returned to the State Water Pollution Cleanup and Abatement Account. (g) The city, county, other public agen- cy, or state board on behalf of a regional board, may at any time release all or any portion of the property subject to a lien im- posed pursuant to subdivision (f) from the lien or subordinate such lien to other liens and encumbrances if it determines that the amount owned is sufficiently secured by a lien on other property or that the release or subordination of such lien will not jeopar- dize the collection of such amount owed. A certificate by such board, city, county, or other public agency to the effect that any property has been released from such lien or that such lien has been subordinated to other lisns and encumbrances shall be con- clusive evidence that the property has been released or that the lien has been subor- dinated as provided in such certificate. (n) As used in this section, the words "nonoperating" or "not in operation" means the business is not conducting routine operations usually associated with that kind of business. 13306. A majority vote of the entire membership of a regional board shall be required to adopt, rescind, or modify any enforcement action authorized by Section 13301. Article 2.

Upon finding that the action the regional board, or the failure of the regional board to act. was inap- propriate or improper, the state board may direct that the appropriate action be taken by the regional board, refer the matter to any other state agency hav- ing jurisdiction, take the appropriate action itself, or any combination of the foregoing. In taking any such action, the state board is vested with all the powers of the regional boards under this division. (d) In the event a waste discharge in one region affects the waters in another region and there is any disagreement between the regional boards involved as to the re- quirements which should be established, either regional board may submit the dis- agreement to the state board which shall determine the applicable requirements. 13321.

(b) "Public agency" means any city, county, city and county, district, or other political subdivision of the state. (c) "Facilities" means: (1) facilities for the collection, treatment, or export of waste when necessary to prevent water pollution, (2) facilities to reclaim waste waters and to convey reclaimed water, (3) facilities or devices to conserve water, or (4) any combination of the foregoing. 13401. The State Water Quality Control Fund is continued in existence. The follow- ing moneys in the fund are appropriated, without regard to fiscal years, for expen- diture by the state board in making loans to public agencies in accordance with the provisions of this chapter: (a) The balance of the original moneys deposited therein. (b) Any money repaid thereto.

CHAPTER 7. WATER RECLAMA- TION Article 1. Short Title 13500. This chapter shall be known as and may be cited as the Water Reclama- tion Law. Article 2. Declaration of Policy 13510. It is hereby declared that the peo- ple of the state have a primary interest in the development or facilities to reclaim water containing waste to supplement ex- isting surface and underground water supplies and to assist in meeting the future water requirements of the state. 13511. The Legislature finds and declares that a substantial portion of the future water requirements of this state may be economically met by beneficial use of reclaimed water. The Legislature further finds and declares that the utilization of reclaimed water by local communities for domestic, agricultural, industrial, recreational, and fish and wildlife purposes will contribute to the peace, health, safety and welfare of the people of the state. Use of reclaimed water constitutes the development of "new basic water supplies" as that term is used in Chapter 5 (commencing with Section 12880) of Part 6 of Division 6. 13512. It is the intention of the Legislature that the state undertake all possible steps to encourage development of water reclamation facilities so that reclaimed water may be made available to help meet the growing water requirements of the state. Article 3, State Assistance 13515. In order to implement the policy declarations of this chapter, the state board is authorized to provide loans for the development of water reclamation facilities, or for studies and investigations in connection with water reclamation, pur- suant to the provisions of Chapter 6 (commencing with Section 13400) of this division. Article 4. Regulation of Reclamation 13520. As used in this article "reclama- tion criteria" are the levels of constituents of reclaimed water, and means for assurance of reliability under the design concept which will result in reclaimed water safe from the standpoint of public health, for the uses to be made. 13521. The State Department of Health Services shall establish statewide reclama- tion criteria for each varying type of use of reclaimed water where such use involves the protection of public health. 13522. Whenever the State Department of Health Services or any local health of- ficer finds that a contamination exists as a result of use of reclaimed water, the department or local health officer shall order the contamination abated in accor- dance with the procedures provided for in Chapter 6 (commencing with Section 5400) of Part 3, Division 5 of the Health and Safety Code. 13522.5. (a) Any person reclaiming or proposing to reclaim water or using or proposing to use reclaimed water within any region for any purpose for which reclamation criteria have been established, shall file with the regional board of that region a report containing such informa- tion as may be required by the board. (b) Every person reclaiming water or us- ing reclaimed water shall file with the regional board of that region a report of any material change or proposed change in the character of the reclaimed water or its use. (c) Each report under this section shall be sworn to or submitted under penalty of perjury. (d) The provisions of this section shall not be construed so as to require any such report in the case of any producing, manufacturing, or processing operation, involving the reclamation of water solely for use in such producing, manufacturing, or processing operation. 13522.6 Any person failing to furnish a report under Section 13522.5 when so re- quested by a regional board is guilty of a misdemeanor. 13522.7 The Attorney General, at the request of the regional board, shall petition the superior court for the issuance of a temporary restraining order, temporary injunction or permanent injunction, or combination thereof, as may be ap- propriate, requiring any person not com- plying with Section 13522.5 to comply forthwith. 13523. Each regional board, after con- sulting with and receiving the recommen- dations of the State Department of Health Services and after any necessary hearing, shall, if it determines such action to be necessary to protect the public health, safe- ty, or welfare, prescribe water reclamation requirements for water which is used or proposed to be used as reclaimed water. Requirements may be placed upon the per- son reclaiming water, the user, or both. Such requirements shall include, or be in conformance with, the statewide reclama- tion criteria established pursuant to this article. The regional board may require the submission of a preconstruction report for the purpose of determining compliance with the reclamation criteria. 13523.5. A regional board may not deny issuance of water reclamation require- ments to a project which violates only a salinity standard in the basin plan. 13524. No person shall reclaim water or use reclaimed water for any purpose for which reclamation criteria have been es- tablished until water reclamation re- quirements have been established pursuant to this article or a regional board deter- mines that no requirements are necessary. 13525. Upon the refusal or failure of any person or persons reclaiming water or us- ing reclaimed water to comply with the provisions of this article, the Attorney General, at the request of the regional board, shall petition the superior court for the issuance of a temporary restraining order, preliminary injunction, or perma- nent injunction, or combination thereof, as may be appropriate, prohibiting forthwith any person or persons from violating or threatening to violate the provisions of this article. 13525.5. Any person reclaiming water or using reclaimed water in violation of Sec- tion 13524, after such violation has been called to his attention in writing by the regional board is guilty of a misdemeanor. Each day of such reclaiming or use shall constitute a separate offense. 13526. Any person who, after such ac- tion has been called to his attention in writing by the regional board, uses 3-22-85 Published by THE BUREAU OF NATIONAL AFFAIRS. INC.. Washington. D.C. 20037 721:0122 STATE WATER LAWS reclaimed water for any purpose for which reclamation criteria have been established prior to the establishment of water reclamation requirements, is guilty of a misdemeanor. 13527. in administering any statewide program of financial assistance for water pollution or water quality control which may be delegated to it pursuant to Chapter 6 (commencing with Section 13400) of this division, the state board shall give added consideration to water quality control facilities providing optimum water reclamation and use of reclaimed water. Nothing in this chapter prevents the ap- propriate regional board from establishing waste discharge requirements if a dis- charge is involved. 13528. No provision of this chapter shall be construed as affecting the existing powers of the State Department of Health Services. Article 5. Surveys and Investigations 13530. The department, either in- dependently or in cooperation with any person or any county, state, federal, or other agency, or on request of the state board, to the extent funds are allocated therefor, shall conduct surveys and in- vestigations relating to the reclamation of water from waste pursuant to Section 230. Article 6. Waste Well Regulation 13540. No person shall construct, main- tain or use any waste well extending to or into a subterranean waterbearing stratum that is used or intended to be used as. or is suitable for, a source of water supply for domestic purposes. Notwithstanding the foregoing, when a regional board finds that water quality considerations do not preclude controlled recharge of such stratum by direct injection, and when the State Department of Health Services, following a public hearing, finds the proposed recharge will not impair the quality of water in the receiving aquifer as a source of water supply for domestic pur- poses, reclaimed water may be injected by a well into such stratum. The State Department of Health Services may make and enforce such regulations pertaining thereto as it deems proper. Nothing in this section shall be construed to affect the authority of the state board or regional boards to prescribe and enforce re- quirements for such discharge. 13541. As used in this article, "waste well" includes any hole dug or drilled into the ground, used or intended to be used for the disposal of waste. Article 7. Waste Water Reuse 13550. The Legislature hereby finds and declares that the use of potable domestic water for the irrigation of green be It areas, including, but not limited to, cemeteries, golf courses, parks, and highway landscaped areas, is a waste or an un- reasonable use of such water within the meaning of Section 2 of Article X of the California Constitution when reclaimed water which the state board, after notice and a hearing, finds meets the following conditions is available: (a) The source of reclaimed water is of adequate quality for such use and is available for such use. (b) Such reclaimed water may be fur- nished to such greenbelt areas at a reasonable cost for facilities for such delivery. In determining reasonable cost, the state board shall consider all relevant factors, including, but not limited to. the present and projected costs of supplying potable domestic water to affected greenbelt areas and the present and pro- jected costs of supplying reclaimed water to such areas, and shall find that the cost of supplying such reclaimed water is com- parable to. or less than, the cost of supply- ing such potable domestic water. (c) After concurrence with the State Department of Health Services, the use of reclaimed water from the proposed source will not be detrimental to public health. (d) Such use of reclaimed water will not adversely affect downstream water rights, will not degrade water quality, and is determined not to be injurious to plantiife. The state board may require a public agency or person subject to this article to furnish such information as may be rele- vant to making the findings required by this section. 13551. A person or public agency, in- cluding a state agency, city, county, city and county, district, or any other political subdivision of the state, shall not use water from any source of quality suitable for potable domestic use for the navigation of greenbelt areas when suitable reclaimed water is available as provided in Section 13SSO; provided that any such use of reclaimed water in lieu of the extraction of ground water shall, to the extent of such reclaimed water so used, be deemed to constitute a reasonable beneficial use of the ground water and such use of reclaim- ed water shall not cause any loss c; diminution of any existing water right however acquired. CHAPTERS. FEDERAL ASSISTANCE FOR TREATMENT FACILITIES 13600. The state board shall administer any program of financial assistance for water quality control which may be delegated to it by law, and may accept funds from the United Slates or any per- son to that end. 13601. The state board, in cooperation with the regional boards, shall survey the statewide need for waste collection, treat- ment and disposal facilities which will be required during the five-year period, January 1, 1968, to December 31,1972, in- clusive, to adequately protect the waters of the state for beneficial use. The state board shall also, biennially, commencing in 1970, survey the need for facilities which will be required by public agencies for the ensuing five-year period. The state board may re- quest a local public agency operating such facilities to transmit to its regional board a report on ihe following: (a) A summary of the construction or improvement of its waste collection, treatment and disposal facilities and amounts expended therefor. (b) An estimate of its needs for five-year period, January 1. 1 ,.,, to December 31, 1972. inclusive, and for any- ensuing five-year period. The state board shall review the infor- mation contained in the reports made by the local public agencies. The state board shall submit to the Legislature findings and conclusions as to the anticipated local, state, and federal financing necessary to provide the needed facilities for such periods. 13602. The state board shall make no commitment or enter into any agreement pursuant to an exercise of authority under this chapter until it has determined that any money required to be furnished as the Environment Reporter CALIFORNIA PORTER—COLOGNE ACT S-14 721:0123 fin E m It IP state's share of project COM is available for such purpose. 13603. The Governor may request the funds required to finance the state's share of project costs for each fiscal year through inclusion of the anticipated state's share in the annual Budget Bill. 13604. The state board shall review and approve each waste collection, treatment, and disposal project for which an applica- tion for a grant under the Federal Water Pollution Control Act has been made. The state board shall, in reviewing each pro- ject, determine whether such project is in conformity with state policy lor water quality control and in conformity with water quality control plans adopted by regional board, and shall certify that such project is entitled to priority over other eligible projects on the basis of financial as well as water pollution control needs. 13605. For the purpose of reviewing applications for grants made pursuant to authority granted in Section 13600. the state board shall give added consideration to applicants having facilities providing optimum water reclamation and use of reclaimed water. 13606. If an application states that the applicant is not able to finance the local agency share of the project, the state board shall consider whether the applicant should be required to levy a sewerage service, charge. If the state board determines a sewerage service charge is necessary to pay costs, the state board shall not approve the grant application unless, as a condition to such approval, the applicant agrees to levy a reasonable and equitable sewerage ser- vice charge in connection with the propos- ed project. Any such applicant, not otherwise authorized, is authorized by this section to levy a sewerage service charge pursuant to such an agreement, and shall levy such charge in the manner provided in the agreement. 13607. All money appropriated by the Legislature for the state's share of the pro- ject costs shall he appropriated without regard to fiscal years, or shall augment an appropriation without regard to fiscal years. 13608. After the effective date of the amendment of this section by the 1972 Regular Session of the Legislature, no application for a grant under this division or under the Federal Water Pollution Con- trol Act, or amendment thereof, or for a loan pursuant to Chapter 6 (commencing with Section 13400) of this division, shall be accepted by the state board unless such application contains assurances that super- visors and operators af the plant meet or will meet certification requirement*;, adopted pursuant to Chapter 9 (commen- cing with Section 13625) of this division, for the proposed plant, as well as the plant in current operation. 13609. Each applicant for a grant under this chapter for a project to be funded by the federal fiscal 1973-74 allotment and all federal allotments thereafter shall pay to the state board a reasonable grant process- ing fee not to exceed one-half of 1 percent of total eligible project costs according to a fee schedule established by the state board. 13610. The fee authorized by Section 13609 shall be an eligible project cost for grants from the State Clean Water Fund. Section 13609 shall not apply unless the fee is an eligible project cost of the grant ob- tained under the Federal Water Pollution Control Act. 13611. Fees collected under the provisions of Section 13609 shall be deposited in the State Clean Water Grants Administration Revolving Fund, which fund is hereby created. 13612. The Department of Finance in conjunction with the state board shall, from time to time, review the status of the State Clean Water Grants Administration Revolving Fund to determine whether the amount of money therein is adequate to carry out the provisions of this chapter. If the Department of Finance determines that there are excess amounts in the fund, it shall notify the State Controller who shall effect the necessary transfer to the General Fund. The expenditures from the State Clean \Vater Grants Administration Revolving Fund shall be subject to annual appropria- tion in the Budget Act. except that for the !9~4-~5 fiscal year such expenditures as are determined necessary by the state board subject to approval of the Depart- ment of Finance and Section 28 of the Budget Act of 1974 may be made.

The report shall contain such recommended standards for water well and cathodic protection well construc- tion, maintenance, abandonment, and destruction as. in the department's opi- nion, are necessary to protect the quality of any affected water. 13801. The regional board upon receipt of a report from the department shall hold a public hearing on the need to establish such well standards for the area involved. The regional board may hold such a public hearing with respect to any area regardless of whether a report has been received from the department if it has information that such standards mav be needed. 13802. If the regional board finds that standards of water well and cathodic protection well construction, maintenance, abandonment, and destruction are needed in any area to protect the quality of water used, or which may be used, for any beneficial use, it shall determine the area to be involved and so report to each affected county and city in the area. The report shall also contain any well stan- dards which have been recommended by the department. 13803. Each such affected county and city shall, within 120 days of receipt of the report, adopt an ordinance establishing standards of water well and cathodic protection well construction, maintenance, abandonment, and destruction for the area designated by the regional board. Prior to adoption of such ordinance each affected county and city shall consult with all in- terested panics, including licensed well drillers. A copy of such ordinance shall be sent to the regional board on its adoption and the regional board shall transmit such ordinances to the department for its review and comments. 13804. Such county and city well stan- dards shall take effect 60 days from the date of their adoption by the county or city unless the regional board, on it own mo- tion, or on the request of any affected per- son, holds a public hearing on the matter and determines that the county or city well standards are not sufficiently restrictive to protect the quality of the affected waters. If the board makes such a determination it shall so report to the affected county or city and also recommend the well stan- dards, or the modification of the county or city well standards, which it determines are necessary. 13805. If a county or city fails to adopt an ordinance establishing water well and cathodic protection well construction, maintenance, abandonment, and destruc- tion standards within 120 days of receipt of the regional board's report of its deter- mination that such standards are necessary pursuant to Section 13802, or fails to adopt or modify such well standards in the manner determined as necessary by the regional board pursuant to Section 13804 within 90 days of receipt of the regional board's report, the regional board may adopt standards for water well and cathodic protection well construction, maintenance, abandonment, and destruc- tion for the area. Such regional board well standards shall take effect 30 days from the date of their adoption by the regional board and shall be enforced by the city or county and have the same force and effect as if adopted as a county or city ordinance. 13806. Any action, report, or determina- tion taken or adopted by a regional board or any failure of a regional board to act pursuant to this article, or any county or city ordinance in the event of the failure of a regional board to review such ordinance pursuant to Section 13804, may be review- ed by the state board on its own motion, and shall be reviewed by the state board on the request of any affected county or city, in the same manner as other action or inac- tion of the regional board is reviewed pur- suant to Section 13320. The state board has the same powers as to the review of ac- tion or inaction of a regional board or of a county or city ordinance under this article as it has as to other action or inaction of a regional board under Section 13320. in- cluding being vested with all the powers granted a regional board under this article, with like force and effect if it funds that ap- propriate action has not been taker, by a regional board. Any action of a regional board under this article or any county or city ordinance affected by the review of the state board shall have no force or effect during the period of the review by the state board. m mi r*L 3-22-85 Pubhsned by THE BUREAU OF NATIONAL AFFAIRS.

The report shall be amended prior to any modification to the ^^ *l project. The report shall describe the manner by which the projects will comply with the Wastewater Reclamation Criteria and conform to the Guidelines h* for Use of Reclaimed Water. The Wastewater Reclamation Criteria are containedIP» ta in Sections 60301 to 60355, inclusive, of the California Administrative Code, "" Title 22, and prescribe: ta» + Reclaimed water quality and wastewater treatment requirements for the *"» various forms of uSe of reclaimed water, and fcM + Reliability features required for the treatment facilities to ensure _ safe performance. DM ^ Section 60323 of the Wastewater Reclamation Criteria specifies that the report *• be prepared by a properly qualified engineer, registered in California and """ experienced in the field of wastewater treatment. <p» ta Reclamation projects vary in complexity. Therefore, reports will vary in *•» content, and the detail presented will depend on the scope of the proposed H •project and the number and nature of the agencies involved in the production, P^ distribution, and use of the reclaimed water. The report must contain _ sufficient information to assure the regulatory agencies that the degree of treatment and reliability is commensurate with the proposed use, and that the H distribution and use of the reclaimed water will not create a health hazard ori nuisance. fI. «• • *, 2.0 PRODUCER m The producer is the public or private entity that will treat the wastewater used in the project. Where more than one agency is involved in the treatment, the responsibilities of each agency must be described. •M 2.1 Reclaimed Water m H State the treatment processes and quality of water that are required and will be provided for each use. to 2.2 Raw Wastewater _ 2.21 State the chemical quality. ** 2.22 State the proportion and type of industrial waste. 2.3 Treatment Processes 2.31 Provide a schematic of the treatment train. «* ''2.32- Describe-the treatment-processes and the loading rates and/or contact tines.

M 2.4 Plant Reliability Features The plant reliability features proposed to comply with Sections 60333 -• JM™ 60355 of the Wastewater Reclamation Criteria must be described in detail. B The discussion of each reliability feature must state under what conditions it will be actuated. When alarms are used to indicate system S . failure, the report must state where the alarm will be received, how the f» location is manned, and who will be notified. The report must state the*hours the plant will be manned. 2.5 Supplemental Water Supplym The report must describe all supplemental water supplies. The description must include: M + SourceP» «• + Quality ^ + Quantity available m 2.6 Monitoring urn • . M ...'"..The report must describe a monitoring program than complies with the Wastewater Reclamation Criteria, and includes the frequency and locationm of sampling. Where continuous analyses and recording equipment is used, IP iH the method and frequency of calibration must be stated. All analyses m shall be performed by a laboratory approved by the State Department of |k| Health Services. p ^ 2.7 Contingency Plan K Section 60323 (c) of the Wastewater Reclamation Criteria requires that the engineering report contain a contingency plan designed to prevent^p M •. •— inadequately treated wastewater from being delivered to the user. The ^ "Contingency Plan" must include: + A list of conditions which would require an immediate diversion to take 1 Place: + A description of the diversion procedures; pi HI -i- Designation of the diversion area; p + A plan for the disposal or treatment of any inadequately treated |l effluent; + A plan for notifying the reclaimed water user, the regional board, the K state and local health departments, and other agencies as appropriate of • any treatment failures that could result in the delivery of inadequately treated uastewater to the use area. Pi p •i *(•» „. 3.0 TRANSMISSION AND DISTRIBUTION SYSTEMS Ota Maps shoving the location of the transmission facilities and the ^ distribution system layout must be provided. The plans must include the ** location of all water and sewer lines. The report must describe how the transmission and distribution systems will comply with the following documents: «• + Guidelines for the Distribution of Kon-potable Water, California-Nevada Section AWWA m + Guidelines for Use of Reclaimed Water (DOHS) m + Regulations Relating to Cross-Connect ions (Title 17, Chapter 5, Subchapter 1) m + Manual of Cross-Connect ion Control / Procedures and Practices (DOHS) *•* Any deviation from the above, and the necessity therefore, must be discussed in the report. Mi ' 4.0 USE AREAS •* A.I Use Area Description m The description of each use area must include: + The land use; P* + The type of reuse proposed; + The party responsible for the distribution and use of the reclaimed m' water at the site; Hi + A map showing: - Specific areas of use m v - Areas of public access Hi - Surrounding land use P - The location of wells in or near the use area to In addition to the general information, the following must be provided for these specific proposed uses: + Irrigation - Type of irrigation (e.g. landscape, specific food crop) - Method of irrigation (e.g. spray, flood, drip) ~ The location of domestic water supply facilities in or adjacent to the use area - The depth to groundwater underlying the use area and a description of the quality - The direction of drainage and a description of the area to which the drainage will flow - For spray irrigation a wind rose or the best available wind data are needed - The proposed irrigation schedule + Inpoundraents - The type of recreational activity to be allowed on the impoundment - The conditions under which the impoundment can be expected to overflow and the expected frequency - The direction of drainage and a description of the area to which the drainage will flow - The depth to groundwater underlying the use area and a description of the quality and use of the groundwater - A description of the soil profile underlying the use area + Cooling - Type of cooling system - A wind rose or the best available wind data + Groundwater Recharge - The appropriate information shall be determined on a case by case basis IP m mi^i&i •*• Other Industrial Uses - The appropriate information shall be determined on a case by case basis 4.2 Use Area Design The report must discuss how the facilities will be designed to minimize the chance of reclaimed water leaving the designated use area. The design must be in conformance with the Guidelines for Use of Reclaimed Water. Any proposed deviation from the Guidelines, and the necessity therefore, must be discussed in the report. Any domestic water distribution system • shall be protected from the reclaimed water in accordance with the Regulations Relating to Cross-Connections. 4.3 Use Area Inspections and Monitoring Identify the locations.at the use area where problems are most likely to occur (e.g. ponding, runoff, overspray) and propose a program of inspection and reporting. 4.4 Contingency Plan The report must identify the actions and precautions to be taken to protect the public health in the event inadequately treated water is delivered. The plan must include notification of the appropriate regulatory agencies and the exposed public. The plan must discuss the provisions for a backup water supply. P to 4.5 Employee Training urn *i The report must describe the training the use area employees will receive ** to ensure compliance with the Wastewater Reclamation Criteria and • Guidelines for Use of Reclaimed Water. The report must identify the . entity that will provide the training and the frequency of training. ** 4.6 Rules and Regulations m The procedures, restrictions, and other requirements that are to be p IB followed by the distributor and/or user must be described. The Ml requirements and restrictions should be codified into a set of rules and m regulations. The "Rules and Regulations" should be developed in P .jug . accordance with "Guidelines for Use of Reclaimed Water". The Rules and _ Regulations should include measures to be used to protect the public §m health and prevent cross-connections. Describe in the report the ffi feasibility of the adoption of enforceable Regulations to cover all the distribution systems and use areas, and identify the agency or agencies P JH that would adopt them.

Since the completion of the plant, the City of Carlsbad has been responsible for operation and maintenance of the facility. The plant, though, has never been in use for wastewater treatment because the sewer moratorium which prompted its construction was lifted when the Encina Water Pollution Control Facility (WPCF) expansion was completed in 1981, and the required distribution system for reclaimed water from the treatment plant was never constructed. As part of the City of Carlsbad's contract with the City of Vista, which is leasing to Carlsbad a portion of its treatment capacity at the Encina WPCF for about three years, until the current expansion of the Encina WPCF is completed, testing of the Lake Calavera plant with wastewater was undertaken in April 1989. While the presence of the treatment plant has not been an issue in past years, since it had not been in service, the recent testing of the plant with wastewater has focused attention on the plant. In 1988, a report on the reclamation facility was prepared by Wilson Engineering to assess the status of the plant and to evaluate what would be required to bring the plant in operation. The report determined that the ultimate service area that could reasonably served by the treatment plant was only about 0.88 mgd, even though the plant was designed for a flow of 1.2 mgd. The report also determined that the cost to operate the plant would be $360,000 annually, and that the capital cost for construction of the required tertiary facilities to meet the Title 22 guidelines would be $1,028,000. In addition about $1,600,000 for the effluent pump station and effluent disposal pipeline and solids disposal pipeline would be required. This report will provide an analysis of the feasibility of continued operation of the Lake Calavera Hills WRP for reclamation in comparison to treatment at the Encina WPCF, and determine the costs of ceasing operations at the plant, dismantling the facilities, with the salvage value of various equipment and materials. 1.2 LAKE CALAVERA HILLS TREATMENT PLANT FOR RECLAMATION From the analysis of the markets that were analyzed in Chapter 7 of the Water Reclamation Master Plan, it was determined that reclaimed water would need to be treated to Title 22 requirements for reuse. In Chapter 9 of this Master Plan, an analysis was provided to compare the cost of producing Title 22 reclaimed wastewater at the Lake Calavera Hills WRP treatment at the Encina WPCF. Based on the cost of Title 22 treatment alone, it was determined that reclaimed water treatment at the Encina WPCF would be the most cost effective alternative. The comparison of the relative costs of the Title 22 treatment is provided in Table 1. The costs presented in Table 1 are based only on the additional facilities required for Title 22 treatment at both treatment plants, and do not include the effluent distribution system nor any modifications to the Lake Calavera Hills WRP for sludge handling or effluent disposal. Sludge disposal at the Lake Calavera Hills WRP should be handled by conveying of the waste activated solids in a new solids disposal pipeline to the Encina WPCF, even though the plant does have an aerobic digester and a belt filter press. For effluent disposal an effluent pump station and completion of an effluent pipeline to the Encina WPCF would be needed. Presently approximately half of the effluent has been or will be constructed. The cost of the solids disposal line had been previously estimated by Wilson Engineering to be about $300,000, with the cost of the effluent disposal line and effluent pump station at about $1,300,000. The Lake Calavera Hills WRP presently has chlorination equipment consisting of chlorinators and a chlorine contact tank, but the detention time in the chlorine contact tank is 30 minutes at peak flow. The chlorination process cost is to provide for a detention time of 120 minutes at average flow, or about 80,000 gallons. m b Table 1 Treatment Construction Costs Treatment Process Construction Cost, in dollars Encina WPCF Calavera Hills Coagulation/Flocculation Filtration Chlorination Subtotal Engineering, 15% Administration, 10% Construction Contingency, 15% Total $16,000 165,000 49,000 230,000 34,000 23,000 35,000 $322,000 $52,000 523,000 121,000 852,000 128,000 85,000 129,000 $1,038,000 The estimated annual operation and maintenance (O&M) costs, excluding the annualized capital costs, for the Lake Calavera Hills WRP with Title 22 treatment was derived from adding the secondary treatment costs of $360,000 from the Wilson Engineering report, plus the additional annual conveyance costs for pumping to the plant of $80,000, to the estimated annual operating cost for the Title 22 facilities of $128,000, for a total of $568,000. Based on the treatment of 0.88 mgd, the annual operating cost of producing Title 22 reclaimed wastewater would be $446 per acre-foot (AF) for the secondary facilities and $130 per AF for the Title 22 facilities for a total of $576 per AF. The cost of treatment at the Encina WPCF under Alternative 1, from Table 9-9, would be about $225 per AF for the secondary treatment, which does not include annualized capital costs, plus $90 per AF for the Title 22 facilities for a total of $315 per AF, as, shown in Table 2. Note that this comparison does not include any annual sludge disposal costs nor effluent disposal for the Lake Calaveras Hills WRP.

From the marketing analysis presented in Chapter 7, the <•» peak daily water use projected at build out of the golf course is about 900,000 gpd, which is slightly more than the projected throughput of the treatment plant. Delivery of the reclaimed water will require an effluent •• pump station and distribution piping; the estimated cost of these facilities are $300,000 for the effluent |l pump station and $600,000 for the effluent distribution pipeline. Since the cost to provide reclaimed water to the golf course would also need to include the cost to modify the Calaveras Hills WRP to produce Title m 22 water of $2,630,000, the total capital cost would be $3,530,000, assuming no on site storage of reclaimed water at the golf course. If provisions were made to construct the estimated fail safe storage * volume of 243 acre-feet at the golf course, the total construction cost would be reduced to $2,230,000. The annual operating cost of the plant would be about the same as that shown in Table 2. if 1.4 LAKE CAUWERA HILLS WATER RECLAMATION PLANT DISMANTLING P* The cost of dismantling the Lake Calavera Hills WRP was based on removal and salvage of the usable m equipment and demolition and the demolition and removal of all above grade structures, and filling of all below grade depressions. Site improvements such as asphalt paving and fencing would be removed, but p storm drainage structures and piping would remain. Mechanical piping on the site and within structures _ would be removed and valves would be salvaged. Upon completion of the demolition work, the entire *l treatment plant site would be regraded to a uniform grade for drainage. The cost summary for the demolition of the plant is presented in Table 3. ^W IH Much of the mechanical process equipment and valves that can be removed and used or reinstalled without modification can be salvaged. The remaining equipment, in particular specially fabricated «- equipment such as the clarifier collection mechanism, has very little if any salvage value, and has value te only as scrap metal. The expected salvage value of the mechanical equipment is low based on the discussion with equipment suppliers on used process equipment. These values are based on the p, assumption that there is a market for the particular process equipment, which may or may not be the case.

The offender shall, within the period of time stated in such notice, permanently cease all violations. This provision is in addition to, and not by way of, derogation of any other remedies or procedures available to the City by law, regulation, or pursuant to any of the provisions of these Rules and Regulations. Failure to permanently cease all violations within the time stated shall result in revocation of the permit by the City and termination of reclaimed water service. 13.2 INTERIM RECLAIMED WATER SERVICE DISCONTINUATION In cases where the serious nature of the violations described above requires immediate action, the City may, in its sole discretion, immediately cease reclaimed water service, subject to a timely decision on permanent revocation of permit pursuant to a public hearing as provided herein. 13.3 PERMANENT REVOCATION The City may permanently revoke any permit. However, no permit may be permanently revoked until after the customer has been given an opportunity for a public hearing as hereinafter provided. 13.3.1 Where the City determines that a permit should be permanently revoked, the City shall prepare a written notice of permanent revocation which includes a statement of the proposed action, a concise explanation of the reasons for the proposed action, and an explanation of the customer's right to a public hearing. Such notice shall be sent by certified mail to the customer's last billing address or be personally served on the customer at least ten (10) days before the effective date of the proposed permanent revocation. If, within five (5) days after receipt of such notice, the customer or an authorized representative requests in writing a public hearing from the City, the City shall immediately set a hearing and give the customer written notice of the time, date, and place of such hearing, either by personal service or by First Class mail. The hearing shall be held not more than thirty (30) days from the date of receipt of said request for hearing. The hearing shall be conducted by a hearing officer designated by the City. The person designated as hearing officer shall not have been connected in any way with the decision to permanently revoke the subject permit. No hearings shall be continued except upon a showing of good cause. 13.3.2 The hearing officer is authorized to administer oaths to all witnesses, and conduct the hearing. At such hearing the City and the customer may present evidence relevant to the permanent revocation of the permit. The hearing officer shall receive evidence and shall rule on the admissibility of evidence and on questions of law. At the hearing any person may present evidence in opposition to, or in support of, the customer' case. The customer may have the assistance of counsel or may appear by counsel, and shall have the right to present evidence. In the event that neither the customer nor counsel representing the customer appears at the hearing, the evidence of the existence of facts which constitute grounds for the permanent revocation of the permit shall be considered unrebutted. 13-1 13.3.3 (a) Oral evidence shall be taken only on oath or affirmation. (b) Each party shall have these rights: to call and examine witnesses; to introduce exhibits; to cross-examine opposing witnesses on any matter relevant to the issues regardless of whether or not that matter was covered in the direct examination; to impeach any witness regardless of which party first called the witness to testify; and to rebut any evidence given. If the customer does not testify in his or her own behalf, the customer may be called and examined as if under cross-examination. (c) The hearing need not be conducted according to technical rules relating to evidence and witnesses. Any relevant evidence shall be admitted if it is the sort of evidence on which responsible persons are accustomed to rely in the conduct of serious affairs, regardless of the existence of any common law or statutory rule which might make improper the admission of such evidence over objection in civil actions. Heresay evidence may be used for the purpose of supplementing or explaining any direct evidence, but shall not be sufficient in itself to support a finding unless it would be admissible over objection in a civil action. The rules of privilege shall be effective to the same extent that they are now or hereafter may be recognized in civil actions. Unduly repetitious evidence may be excluded at the discretion of the hearing officer. (d) The hearing shall be conducted in the English language. The proponent of any testimony to be offered by a witness who does not speak the English language proficiently shall provide an interpreter, approved by the hearing officer conducting the proceeding as proficient in the English language and the language in which the witness will testify, to serve as interpreter during the hearing. The cost of the interpreter shall be paid by the party requiring the interpreter. 13.3.4 The decision of the hearing officer shall be based solely on the evidence presented at the hearing. Upon conclusion of the hearing, the hearing officer may orally announce an intended decision. Whether or not the hearing officer announces an intended decision at the conclusion of the hearing, the hearing officer shall, within five (5) days of the conclusion of the hearing, file a written decision with the City Council and mail a copy to the customer or his or her authorized representative. The written decision shall include findings of fact and conclusions of law, shall clearly state whether the permit is or is not permanently revoked, and shall become final upon filing with the City. A copy of the written decision shall be posted in the office of the City Clerk for a period of five (5) days following its receipt. 13.4 RE-ESTABLISHMENT OF RECLAIMED WATER SERVICE Any request to re-establish service subsequent to the revocation of a permit and the termination of reclaimed water service shall be in the manner described for initially obtaining service from the City, which may include the collection of a security deposit. The City may, at its discretion, deny re-establishment of service or require that an agreement of financial security conditioned upon compliance with these Rules and Regulations be provided. The foregoing provisions of these Rules and Regulations are a requirement of any permit, and any application for service and permit therefore shall be subject to such provisions. 13-2 APPENDIX A APPLICATION FORM FOR RECLAIMED WATER SERVICE WITHIN THE CITY OF CARLSBAD (Please type or print all information) User Account # (by City) Descriptive Information (Completed by Owner or Authorized Representative) Owner of Property Organization Name Responsible Individual Title Owner's Address Owner's Telephone Authorized Representative of Owner Responsible Individual Title Authorized Representative's Address Authorized Representative's Telephone Property Location (City) Property Use Property Description Intended use for reclaimed water Total area to be actually irrigated with reclaimed water per this application. acres.
