HomeMy WebLinkAbout; 2004 Phase II Recycled Water Implementation Plan; 2004 Phase II Recycled Water Project Implementation Plan; 2004-04-01This Implementation Plan complies with all requirements for "target" and "optimum" of Goal No. 442. Target is met through the completion of this Implementation Plan, which includes recommendations on connecting customers, City staffing and community outreach. Optimum is met through completion of several tasks including: • Obtaining a commitment from the Department of Environmental Heath to meet our schedule in connecting customer use sites to the Phase II system • Completing the connections required for fiscal year 2003/2004, and • Initiating the community outreach program. The recommendations contained in this plan will be implemented unless othenwise directed. Budget costs for conversions and retrofits can be presented to the Leadership Team or City Council for their consideration at this time. The following team members developed the Implementation Plan, and we welcome any comments or questions. Recycled Water Retrofit Team Members David P. Ahles, Senior Civil Engineer Team Leader, Goal No. 442 Terry^mith, Senior Civil Engineer Engineer Chapter 1 Background and Purpose Background In 1991, the Carlsbad Municipal Water District (CMWD) began developing a recycled water system referred to as the Encina Basin Water Reclamation Program, Phase I. The Phase I system was completed ini994 and is capable of delivering up to 2,050 acre-feet per year (AFY) of tertiary treated recycled water. Since 1997, the CMWD has been developing the Encina Basin Water Reclamation Program, Phase II. Phase II is designed to increase the recycled water demand to 5,000 AFY in combination with Phase I. This increased recycled water demand reduces the CMWD's overall dependence on imported water by meeting approximately 20 percent of CMWD's ultimate average annual demand of 28,000 AFY. Through an agreement dated March 28, 2000, between the Metropolitan Water District of Southern California (MWD) and the CMWD, the Phase II project receives a rebate for every acre-foot of recycled water sold provided the CMWD increases its demand above 2,050 AFY. The increase in demand must begin in fiscal year 2004/2005, and then incrementally increase every four years until a yield goal of 5,000 AFY is reached. If incremental increases in the annual yield specified in the agreement are not met, then MWD will reduce or eliminate rebate funding, which amounts to over $11 million by the year 2018. Refer to Appendix A for a copy of the agreement. Purpose The purpose of this "Implementation Plan" is to provide recommendations on procedures and City staffing required to achieve the recycled water yield stipulated in the MWD agreement. The plan is divided into eight chapters addressing the following subjects: • Location and demand of Phase II recycled water irrigation use sites. • Priority to be used in connecting different use sites to the Phase II distribution system. • Construction schedule for Phase II facilities and its impact on connecting use sites. • The schedule to connect every use site to the Phase II system, and the commitment from Department of Environmental Health to meet the schedule. • Staffing required for a recycled water retrofit and cross-connection testing program, and the operation and maintenance program for the Phase II system. • Recommended methodology to perform onsite retrofits and conversions, and associated cost and possible financing options for this work. • Recommended community outreach program and its implementation. Chapter 2 Customer Use Sites Background The State of California defines a use site as an area of recycled water use with defined boundaries. A use site may contain one or more facilities or buildings. This could include a single housing tract or an industrial building for example. This Chapter first identifies prospective commercial, industrial and Homeowners Association (HOA) irrigation water use sites that front along pipelines being constructed in the Phase II recycled water distribution system. Second, each use site is placed into one of three categories to account for the different types of work to be perfonned by the City at the use site prior to being able to use recycled water. In 1997, CMWD's Reclaimed Water Master Plan identified potential recycled water use sites for the Phase II project. Using the master plan, CMWD submitted an application to MWD in 1998 for rebate funding indicating a minimum demand of 2,950 AFY from Phase II customers. By January 2000, CMWD estimated the annual demand at 4,327 AFY based on the location of proposed pipelines. This information was subsequently used in applying for loans and grants from the State Water Resources Control Board, and the Bureau of Reclamation for Phase II project funding. In 2003, irrigation water use site demands were re-estimated forthis Implementation Plan using the following information: • Current Phase I recycled water irrigation demands from meter records. • Irrigation water meter records from existing prospective commercial, industrial and HOA use sites fronting along Phase II pipelines. • Projected irrigation demand data from future land development projects. The total annuai irrigation demand from Phase II is now estimated at 4,418 AFY, which will be obtained from 319 additional use sites. This irrigation demand exceeds the MWD requirement of 2,950 AFY providing assurance that the Phase II system will be able to comply with the "rebate agreement" in terms of total yield requirements. Regulatory Oversight to Connect Use Sites Connecting 319 use sites to the Phase II system requires significant coordination efforts between the State Department of Heath Services (DHS), County Department of Environmental Health (DEH), and the City. California Health Laws related to recycled water as of June 2001 require DHS to review: 1. Treatment Plant design, performance criteria, and reliability 2. Allowable uses of recycled water and use area requirements 3. Monitoring and cross connection control at use sites In San Diego County, DHS has an agreement with DEH to perform the use site monitoring and cross connection control. On December 3, 2003 the City met with DEH to review the monitoring and cross connection testing and inspection requirements to be used in connecting each new use site in Phase II. Based on the infonnation presented at the meeting, a final recommended approach was prepared and a formal request was then submitted in a letter dated December 11, 2003 to the DEH. The letter requested DEH approval of the following: • Our approach in connecting each irrigation use site to the recycled water system. • A commitment by DEH to meet our schedule to connect use sites, and • The method to be used in abandoning disconnect vaults allowing conversion of large areas to recycled water at one time. The connection process presented to DEH is described at the end of this chapter. In a letter dated March 15, 2004, the DEH indicated that they would meet our schedule, which also satisfied one of the requirements for "Optimum" in City Goal No. 442. A copy of the City's request letter and the DEH response letter is shown in Appendix B. In March 2004, DEH began efforts to modify their program by proposing to the water purveyors (stakeholders) in the County two main changes. First, they will reduce the time spent observing "shutdown tests" by reducing onsite inspection from 4-hours down to observing only the beginning or the end of the test. This saves the County staff time and reduces the number of staff positions from three full time cross-connection control specialists down to two. Second, they propose to change their fee structure. For construction by developers the fees will be fixed lump sum based on a table of values. Retrofit work will be changed to an houriy rate. Testing will be changed to a flat rate of $60 per year per use site no matter what size the use site is. They assured the City staff that these changes will not affect their commitment to CMWD. However, should the proposed changes not be adopted by their Board, the DEH indicated they may give the program back to DHS because of a lack of adequate funding. In locations where DHS manages the program they have assigned the water purveyor with all oversight responsibilities based on the capability, knowledge, and integrity of the water purveyors staff. Phase II Recycled Water Use Site Database A database was created to indicate actual water demands, billing information, and connection status at each use site. An example of the infonnation contained in the database for one use site is shown at the end of this chapter for reference. This database will be maintained and used by the City on an ongoing basis and has now become part of the overall "water customer" database the City uses for all potable and recycled water billings. Each recycled water irrigation use site in the database was grouped under one of three types of connection categories: • New Developments • Conversions • Retrofits As described below the type of work to be performed by City personnel for each connection category varies. New Developments - This category includes near term land development projects fronting a Phase II pipeline that have been already approved or is anticipated to be approved in the near future for construction by the City. These projects include for example Bressi Ranch, Villages of La Costa, and proposed industrial or commercial buildings. The developer of each "new development" project is required to prepare recycled water use plans for their onsite irrigation system. The City and DEH must review and approve the recycled water irrigation plan before irrigation system construction begins on the development project. As these "new development" projects proceed into construction they also extend distribution pipelines throughout the "new development", which makes up part of the overall Phase II distribution system. After construction, the City also perfonns onsite cross connection (shutdown) and coverage tests of the entire land development project where recycled water is to be used, and assists in scheduling training programs for landscape maintenance personnel through a program offered by the San Diego County Water Authority. Conversions - Conversions require the removal of either an existing "Disconnect Vault" for existing land development projects or conversion of existing potable irrigation meters to recycled water at commercial, industrial and HOA use sites. Each conversion site already has a CMWD / DEH approved onsite recycled water irrigation system plan. For this category the City must perform the work to remove the "disconnect vault" or potable irrigation meter. In addition along with DEH, City staff must also perform shutdown testing and coverage testing, and training of landscape personnel. Existing disconnect vaults were installed for projects such as Rancho Carrillo, and Calavera Hills Villages Q and T. These are currently being used to supply potable water to land development sites already approved for the use of recycled water. An example of an existing industrial site with approved plans includes the City's Faraday Building. Retrofits - These include commercial, industrial and HOA use sites that developed prior to adoption of CMWD Ordinance No. 31 on May 8, 1990 requiring the use of recycled water where it is made available. These projects generally developed prior to 1993. Because these irrigation systems are older, they will need to have retrofit work performed prior to using recycled water. Since no approval was received by DEH, City staff will need to prepare plans of each private recycled water irrigation system for each use site, and then the plans will need to be submitted to the DEH for final approval before retrofit work can be commenced. City staff will be involved in the work to retrofit the irrigation systems, plus monitor construction improvements, and perform cross-connection and coverage tests. For reference, an Implementation Map was created showing the current status of each commercial, industrial and HOA use site identified for the Phase II system. This map is shown in Appendix C and it will be updated as each use site is converted to recycled water. The Connection Process The Regional Water Quality Control Board states 'The Producer shall be responsible to ensure that all users of recycled water comply with the specifications and requirements for recycled water use." In October 1993, the CMWD responded to this requirement by preparing "Reclamation Rules & Regulations for Construction of Reclaimed Water Mains". A portion of the rules and regulations concern the steps to be taken in the connection process. In summary these steps include: 1. Submittal by applicant of a map showing where recycled water will be used. 2. An application form is signed by the applicant whereby he agrees to Carlsbad's rules and regulations for use of recycled water. 3. Submittal of application package to DEH and DHS for their approval. 4. Submittal of detailed construction plans of the irrigation system to City and DEH, for approval and pay required fees. 5. Issuance of a City Permit for Reclaimed Water Service. 6. Pre-Construction conference to answer any questions 7. Construction Inspection by the City of distribution and irrigation piping. 8. Final Field Inspection 9. Perform Cross Connection and Coverage Tests by the City 10. Obtain training for landscape maintenance personnel to properiy work with recycled water. Table 1 on the next page summarizes the types of activities that are required to be perfonned by City personnel. Generally, new developments require the least number of activities followed by conversions and then retrofits.

At the end of this Chapter is supporting information on the water demand anticipated at each use site. Each use site is shown on one of fourteen location maps along with the corresponding pipeline segment designed for Phase II. Also shown on the map is the number of existing meters to be connected to the recycled water distribution system, average water usage, and type of connection (i.e. new development, conversion, or retrofit). Following each location map is a spreadsheet indicating the: • Existing Irrigation Meter Number (if applicable) • Use site Address • Meter size • Existing or projected average annual Irrigation demand in AFY, based on the last 5-years of record • Determination on need for a "Retrofit Plan" at the site? (Yes or No) • Determination on issuance of a DEH approved onsite irrigation plan? (Yes with DEH assigned "RW" number, or no approved plan) RECYCLED WATER PROGRAM DATABASE Q Recycled Water - [Menu-Main : Form] Tools Window Help -Ifflxl % 1 §i li la V 1 w-^ •aa' i ' V 1 Talioma •» 11 " 1 B " i —' Recycled Water Program Main Menu Use Site Form Customer & Backflow Informabon Update Account Information Inspections Menu Test & Maintenance Menu Reports & Queries Menu Non-Compliance Form Test Results & Testers Menu Carlsbad Approved Projects Phase II Menu I Exit Site Supervisor Menu Record: l< I < I \ Form View 1 \ > I M |> >| of 1 CAPS I NUM IStartJlJ ^ CCD |] g]5..| [P]d..| ©R. |M..

These contracts are a result of developers building facilities through reimbursement agreements, combining pipelines with concurrent roadway, park and golf course projects, upgrading other agency's facilities, and constructing master planned facilities under contract. The projects include two treatment facilities, 24 miles of pipelines, three booster-pumping stations, and two reservoirs. A map showing the location of these facilities is in Appendix D. The completion of the projects noted above is necessary in order to supply recycled water for irrigation and other uses to identified use sites. Initial construction of some projects started in January 2002 and completion of all projects is currently scheduled for March 2006. The timeframe in which each construction contract is completed influences the location and order in which connections to the system can occur because various pipelines and pressure zones in the system can be activated while construction continues on remaining projects. This situation allows for connections to be made at several locations in advance of completing the entire system. Following is a discussion on the construction schedule of each major facility group, and there influence on water availability. Treatment Facilities For the Phase II project, recycled water will be supplied from three treatment facilities, which include: 1. Meadowlark Water Reclamation Facility (MWRF), owned by Vallecitos Water District 2. Gafner Wastewater Treatment Plant (GWTP), owned by Leucadia Wastewater District 3. The new Carlsbad Water Recycling Facility (CWRF) owned by CMWD. Following is a discussion on each treatment plant's capacity and supply availability date. MWRF - This treatment plant is being designed to increase its capacity from 2.0 MGD up to 5.0 MGD. In an agreement with Vallecitos Water District dated August 20, 2003, the CMWD will purchase up to 3.0 MGD from April through October and up to 2.0 MGD from November through March of each year from the MWRF. The agreement expires in 2025. In a separate agreement between Olivenhain Municipal Water District and Vallecitos Water District, dated October 24, 2003, Olivenhain will be purchasing up to 1.5 MGD beginning July 1, 2005 from the MWRF. Discussions with Vallecitos Water District indicate that the treatment plant design will be completed in June 2004. The tentative construction schedule calls for completion in eighteen months, which is approximately March 2006. This will be the last project constructed for the Phase II system. Until construction of the expanded treatment facility is completed, no additional recycled water supply above 2.0 MGD will be available from the MWRF. GWTP - This tertiary treatment plant has a discharge order capacity of 1.0 MGD. However, the recycled water is directed only to the south golf course at La Costa Resort. Therefore, the supply from GWTP will only match the demand for irrigation water from the south golf course, which is typically 385 AFY. The GWTP recycled water is supplied to CMWD in accordance with an agreement between Leucadia Wastewater District and the CMWD dated March 25, 1991. The agreement term is for 20 years, which will expire in April 2011. It is uncertain that the agreement with Leucadia Wastewater District will be renewed, resulting in a need to expand the Carlsbad Water Recycling Facility in the near future to meet the Phase II irrigation water demand. CWRF - This is an advanced tertiary treatment facility with a discharge order capacity of 4.0 MGD, which uses a parallel treatment system consisting of granular media filtration and microfiltration followed by reverse osmosis. However, by operating the microfiltration system only in series with the granular media filtration system, the facility can treat up to 4.8 MGD. To revise the flow rate would require an amendment to the existing discharge order prior to using the increased supply. The additional flow will eventually be needed to meet anticipated demand. Secondary treated effluent supplied to this facility is obtained from the Encina Water Pollution Control Facility through an agreement between the City of Carlsbad and the Encina Wastewater Authority (EWA) dated June 26, 2001. The agreement requires that EWA also construct the secondary effluent pump station, the tertiary treated water pump station, and flow equalization tank which are all necessary components of the CWRF. Construction of the CWRF will be completed in May 2004; however, the EWA project will not be completed until April 2005. Therefore, the CWRF will not become operational until April 2005. Reservoirs There are two reservoirs that will be connecting to the Phase II system. The first is CMWD's existing one million-gallon (MG) "C" tank, which will be converted from potable water storage to recycled water storage. The conversion work will be completed when the McMillin Company completes construction of Cannon Road and College Boulevard in September 2004. These streets contain the transmission main that will be used to reach the "C" tank inlet/outlet pipeline. The second project includes Mahr Resen/oir. This is a 54-MG earthen dam storage resen/oir owned by Vallecitos Water District. The CMWD will be making improvements designed to maintain the quality of the recycled water stored in Mahr Reservoir. Design of the improvements is scheduled for completion in June 2004. Construction is tentatively scheduled to be completed in June 2005. Full use of the Phase II system is dependent upon completion of the reservoir improvements. However, by using only the booster-pumping stations a lower initial water demand can be supplied to customers on an interim basis. Booster Pumping Stations There are three booster-pumping stations labeled Twin D, Calavera, and Bressi booster pumping stations. These are used to supply water to higher elevations in the recycled water distribution system. The capacity and schedule of each booster pumping station is described below. Twin D Pumping Station - This facility has the following pumps: • Four 150 HP pumps (3 duty and 1 standby) • Pump capacity is 1,500 gpm each or 4500 gpm total The design of Twin D is completed, and construction is tentatively scheduled for completion in April 2005. This booster pumping station receives flow from the 384- pressure zone and pumps it to Mahr Reservoir to create the 550-pressure zone. The 550-pressure zone will be operational upon completion of Twin D Booster Pumping Station. Calavera Pumping Station - This facility has the following pumps: • 2 duty and 1 standby pump at 60 HP each • Pump capacity is 620 gpm each or 1,240 gpm total The design of Calavera Pump Station is scheduled for completion in April 2004. Construction is tentatively scheduled for completion in May 2005. This facility receives water from the 384-pressure zone and pumps the flow into a closed system using a hydropneumatic tank to maintain pressure and creating the 580-pressure zone. The 580- pressure zone will become operational upon completion of Calavera Pumping Station. Bressi Pumping Station - This facility has the following pumps: • 2 duty and 1 -standby pump at 75 HP each • Pump capacity is 1,080 gpm each or 2,160 gpm total. The Bressi Pumping Station design will be completed in June 2004 and its construction is scheduled for completion in June 2005. This facility pumps water from the 550- pressure zone into a closed system using a hydropneumatic tank to maintain pressure and creating the 660-pressure zone. The 660-pressure zone will become operational upon completion of Bressi Pumping Station. Pipelines There are sixteen pipeline contracts. Pipelines range in size from 30-inches in diameter down to 4-inches in diameter. The last pipeline constructed will be the transmission main included with the City's Rancho Santa Fe Road Phase II project. Although awarded in March 2004, the roadway will not be completed until August 2005. This pipeline will also connect Mahr Resen/oir and MWRF to the pipeline distribution system. Gonstruction of the remaining pipelines is scheduled to be completed by April 2005. 10 Construction Schedule Influence on Use Site Connections Four pressure zones are being created in the Phase II project. Each pressure zone will not become operational until the construction of the corresponding pumping station is completed as noted above. Based on the construction schedule, the lower pressure zones will become operational first which dictates that customer use sites in the lowest pressure zones will be able to connect to the distribution system prior to those in higher elevation pressure zones.

The activities were then compared to the amount of irrigation demand that would be expected from each category. With this information the recommended connection priority is established for each use site category. Potential Yield from Each Connection Category Listed below is a summary of the potential yield estimated for each of the three use categories. New Development - The largest water demand group of use site customers for the Phase II system is "new development" with a potential yield of 2,418 AFY. These customers represent major land development projects under construction or anticipated to be under construction in the next three years. New development within the Phase II system represents almost 60% of the demand on the expanded distribution system. Conversions - Since 1993 the CMWD's Ordinance No. 31 required developers to construct recycled water pipelines and irrigation systems as part of their project requirements. If there is no existing recycled water pipeline neariDy then these new recycled water pipelines are temporarily connected to the potable wateriines through either a "disconnect vault" or a temporary potable irrigation meter. The total anticipated demand from conversions is 1,067 AFY. The "disconnect vaults" are designed to make easier the disconnection from the potable water system and reconnection to the recycled water system when recycled water becomes available. The Phase II project includes pipeline conversions by removing eleven "disconnect vaults". This Chapter identifies Homeowners Association (HOA) irrigation water customers that have recycled water pipelines installed but are connected to the potable water supply. With the construction of the Phase II pipelines, the existing distribution pipelines can be converted to recycled water and have the disconnect vaults removed. A map showing the location of these disconnect vaults is on the next page. Industrial and commercial sites generally approved after 1993 also had their system designed and constructed to use recycled water. There are 100 12 Legend Facility CWRF Encina Basin Water Reclamation Program - Phase II Project - Disconnect Vault Locations January 2004 ^1. vu 1 I Usage VLT Potable Water Disconnect Vault Currently Not In Use In Use With Potable Water In Use With Recycled Water Under Construction Mahr Reservoir Booster Pump Stations Joint Use Facility / Pump Station Pressure Reducing Station Existing Water Reclamation Facilities Meter DATE: 02/04/2004 NAME: LRosu FILE: C:'>GIS ArcViewProject' Plummer'.reclaimedwaler byUsaqe.mxd industrial/commercial use sites that need conversion. These sites are shown on a Map in Appendix C. Retrofits - Retrofits make up the largest number of new connections to Phase II, but when compared to the other two categories will have the least amount of total yield at 933 AFY. These customers include commercial, industrial, and HOA sites, generally constructed prior to 1993, and are identified on the map in Appendix C. Priority of Connections As described in Chapter 2, there is less work effort required by City staff to connect a "new development" to the Phase II system, and, in addition, "new development" has the highest potential irrigation demand compared to conversions and retrofits. Therefore, the financial success of the Phase II program will be greatly enhanced by concentrating City staff time in the initial years to connecting "new development" customers. Based on this information and an overview of the connection process it is recommended that all new developments and conversions be given the highest priority, followed by retrofits because retrofits require the most amount of City staff time and have the least annual yield. Additional consideration must also be given to the time frame for construction of Phase II facilities. For example use sites located in the 260 and 384-pressure zones will be in place prior to the 550-pressure zone and 580- pressure zone. The 660-pressure zone will be the last to be on line because the pumping station supplying this pressure zone will be the last pumping station constructed according to the schedule shown in Chapter 3. In summary, connections will be made in the following priority: 1. New construction and conversion use sites will have a higher priority than use sites requiring retrofit. 2. Use sites in the lowest pressure zones shall have a higher priority for connections to the system than use sites in the higher elevation pressure zones. 13 Chapter 5 Connection Schedule General A connection schedule was established for each use site using the connection priority information presented in Chapter 4, and comparing this information to Metropolitan Water District's rebate agreement conditions. MWD Recycled Water Demand Requirement The rebate agreement with MWD requires that CMWD meet a specified recycled water annual yield, which increases incrementally over a twelve-year period. The annual yield is charted in Table 2 below for reference. The agreement stipulates that if the MWD target yield is reached in any one of the four fiscal years then the agreement condition for that four-year period is satisfied. This condition in the rebate agreement is important because the current construction schedule indicates that full completion of the Phase II system will not occur until March 2006, implying that the first full annual yield increase will not occur until FY 05/06. This situation effectively eliminates the ability to achieve MWD's yield requirement for one to two years of the first four-year period. A second condition in the agreement with MWD states that if the target yield of 2,950 AFY is reached in any one fiscal year, then CMWD has met MWD's requirements; and thereafter, no rebate adjustment will be made by MWD. Table 2 MWD Recycled Water Yield Requirement id Hequireme Bin Fiscal Years 08/09 through 11/12 2,050 AFY 1,858 AFY 3,908 AFY Fiscal Years 12/13 through 15/16 2,050 AFY 2,212 AFY 4,262 AFY (a) When the corresponding MWD target yield is met in any one of the four-year periods then the requirement meets the MWD rebate agreement condition for that four-year period. If the Phase II target yield of 2,950 AFY is reached, then all agreement conditions are also met. 14 Connection Schedule A review was made of the potential yield from each use site. With this information the following detailed breakdown by fiscal year is the proposed schedule to connect use sites and meet the MWD annual target yields listed in Table 3: TABLE 3 RECYCLED WATER YIELD PER FISCAL YEAR Description Water Demand (AFY) FY 2003-2004 New Developments — 2 sites (avallabiHty of operations'staff need to coordinated with Kurt Musser) 1.

Each parcel is color coded on the map to correspond to a fiscal year in which the connection is to occur. For new development projects the year shown is the year connections will begin, but not necessarily completed because it is anticipated it may take three or more years for the industrial lots or residential lots to be fully developed. Table 4 below shows that connections will not meet the MWD demand criteria until fiscal year 2006/07. However, since the demand will reach the target yield requirement before the end of the first four-year demand period the rebate will remain in affect. It is anticipated that by the end of fiscal year 2008/09 the demand will reach or exceed MWD's ultimate Phase II yield requirement of 2,950 AFY.

As shown in Table 4, this yield requirement will be met in FY 07/08. The maximum yield of 2,950 AFY will also be reached in FY 07/08. Therefore, no reduction in the MWD rebate will occur with this connection schedule approach. Another condition is to meet a target yield for Phase I and Phase II combined. This yield is shown in Table 2. The Phase I demand for FY 02/03 was 1,728 AFY, which is less than its planned yield of 2,050 AFY. By adding this to the Phase II yield in Table 4 above the MWD target yield for fiscal years 04/05 through 07/08 will not be reached until fiscal year 06/07. The ultimate target yield of 4,262 AFY should be reached in fiscal year 07/08. In utilizing the connection schedule above a summary graph of the resulting water demand compared to the MWD annual yield requirement is shown below. 20 Q.

Parcels connecting to Phase II pipelines are separated into the three categories described previously. Implementation focuses first on new development followed by conversions, and ending with use sites needing retrofit. As each parcel is connected to the system the map will be updated to reflect the change. The database described in Chapter 2 will also be used in tracking the connection status on each parcel. 22 Chapter 6 Staffing Analysis General This Chapter includes a staffing analysis of the workload required to connect new development, conversions, and retrofits to the recycled water system. It also evaluates the altemative of contracting these services. Finally, a staffing analysis was prepared forthe operation and maintenance of Phase II facilities. Staffing for New Development Connections New Development requires that cross-connection (shutdown) and coverage testing is performed and also verification that the irrigation system was installed in accordance with the DEH approved recycled water irrigation system plans. Upon completion of testing and inspection the landscape maintenance staff for each use site must attend a one-day training class. These classes are provided by the San Diego County Water Authority, which conduct them six or seven times per year. Two of the classes are conducted in Spanish. The City's Cross-Connection Control Section coordinates services for New Development, with the developer's contractor, and DEH. The City's Cross- Connection Control Section has three full time Cross-connection Control Specialists perfonning the required work. Also involved is the Meter Services Section who installs the new irrigation meters and is responsible for monthly reading of the meters. As of this date both Sections in Maintenance and Operations have been able to keep up with the various scheduling needs of developers within the CMWD sen/ice area. Discussions with their supen/isor, Kurt Musser, indicate that they will continue to handle these services; however, if these Sections are unable to comply with any developer's schedule, then the City will establish a priority to perform the work for each new development. If prioritization occurs, the finalizing of the tract mav be delaved. In conclusion no additional staffing is proposed to handle the workload involved in "New Construction" at this time. Staffing for Conversion and Retrofit Connections Approximately 106 use sites will need conversions, and 102 use sites will need to have retrofits. Each use site can vary is size from an industrial building site to a City Park. In order to perform the required sen/ices to meet the MWD agreement conditions, up to approximately 24 conversion sites are planned per year beginning in FY 2004-05, and up to approximately 21 retrofit sites are planned to be completed each year beginning in fiscal year 2005-06. The Cross-connection Control Section does not have sufficient staff to perform the more extensive additional work required for conversions and retrofits. To 23 accomplish this work, the Engineering Department's Design Division can be used to perform the work using two options. First, an Engineering Technician II can be used provided they have completed the American Water Works Association (AWWA) training and testing to become certified Cross-Connection Control Specialists. They would need to be supplemented with two temporary workers or student workers. The initial work effort includes assessing the work that needs to be done at each conversion or retrofit use site. It is planned that they will meet with the property owner and obtain records on the existing potable water system serving the property and also the onsite irrigation system. They will need to also meet with landscape maintenance personnel to determine all aspects of the irrigation system. After obtaining the necessary background information they will prepare irrigation system retrofit plans for approval through DEH. To accelerate the data gathering process, it is planned at this time to use existing City aerial photographs overiayed with property line information, and then locate existing onsite facilities using a mobile GPS handheld system. The GPS data logger can be downloaded to plot the location of various facilities directly onto the aerial photograph. This should significantly reduce irrigation site plan preparation time compared to developing these same drawings using field notes and AutoCAD. To efficiently perform shutdown and coverage testing at each site requires two people. One person operates the controls and records pressure settings, and another person walks the site to observe the resulting irrigation system in operation, and make necessary adjustments. Communication between the two people would be through the use of two-way radios. A summary of the equipment required to perfonn this work include: • Laptop computer $2,000 • Dickson data loggers (at least 2, $400 each, total $800) - need as many as the amount of water meters tested at one location plus one (could be 5 or more, but for the majority of sites just one) Tool box $25 Channel lock pliers (6-1/2" and 9-1/2") $15 Wrenches (8" and 12") $15 Screwdrivers (8" and 14") $5 Teflon tape $5 Misc. hoses, test cocks, etc. $100 Working boots $50 Truck for storage of equipment - use available City vehicle 2-way radios (walkie-talkies) $100 GPS mobile unit $4,000 GPS data collection and office software $2,000 Total equipment budget cost = $10,000. The required number of staff hours to perform this work is shown in Tables 5 and 6 below. After reviewing the tables the following is concluded: 24 City staff time required to complete all conversions and retrofits is 10,976 hours Temporary staff or Student workers may increase total hours by an additional 100 hours. Each Engineering Technician II has other duties. However, by restructuring and prioritizing their activities may allow for 3 to 4 hours per staff person or 8 hours total per day. Number of working days required to complete the work is 1,372 days or 5.5 years. The time frame is acceptable to meet the MWD schedule requirement. The Engineering Technician II with AWWA cross-connection specialist certification will probably require additional training; and therefore, a consultant would be used to provide direction for the initial conversions and retrofits perfonned until efficiency and continuity is achieved. Two -Temporary workers or student workers are required to assist the Engineering Technicians. An option being considered in lieu of temporary workers is to use the assistance of Larry Black and Mike Black to perform construction oversight and to enhance the connection schedule. 25 TABLE 5 - Retrofit Use Sites Line Item Engineering Services Average Number of Work Hours Per Use Site for City Engineermg Line Item Engineering Services Commercial/Industrial HOA 1 Site Survey - Inspect existing on-site systems for potential issues. 16 40 2 Record Review - Obtain and review existing record drawings of proposed improvements to on-site systems. 4 40 3 Ensure proper backflow prevention with regard to fire prevention assemblies. 2 0 4 Prepare and approve through DEH, onsite irrigation system retrofit plans. 12 40 5 Select contractors and hold Pre-construction Meeting 4 4 5 Inspect retrofit on-site system construction 3 30 6 Confirm adequate separation of recycled and potable water facilities 2 8 7 Perform cross connection testing (potable & irrigation) 10 24 8 Perform irrigation coverage testing 4 8 9 Coordinate inspection scheduling and other construction contractor interactions to confirm compliance with CMWD's recycled water rules and regulations. 8 24 10 Final Inspection of contractor installed improvements 3 8 10 Confirm proper recycled water identification 2 8 11 Process preliminary and final as-built plan submittals through DEH 2 8 12 Establish/augment converted site documentation and database records 1 2 13 Miscellaneous - Unforeseen work 4 8 13 Total number of work-hours per use site (a) 77 252 14 Number of Use Sites 84 13 15 Total Number of Work hours to complete all retrofits 6468 3,276 16 Total Number of Work Days to complete all retrofits 809 410 (a) Temporary Workers/student workers may add an additional 12 hours for commercial/industrial use sites and 36 hours for HOA use sites. 26 Table 6 - Conversion Use Sites Line Item Engineering Services Average Number of Work Hours Per Use Site for City Engineering Line Item Engineering Services Commercial/Industrial HOA 1 Site Survey - Inspect existing on-site systems for potential issues. 2 16 2 Record Review - Obtain and review existing record drawings of proposed improvements to on-site systems. 4 8 3 Ensure proper backflow prevention with regard to fire prevention assemblies. 2 0 4 Prepare and approve through DEH, onsite irrigation system retrofit plans.

Several private firms have AWWA certified cross- connection control specialists to perfonn this type of work plus engineers and engineering technicians to prepare irrigation retrofit plans and coordinate their approval through DEH. The work is nonnally perfonned and billed on a time and material basis for several reasons: • Arranging and keeping meetings with property owners and landscape maintenance personnel is difficult in many cases and can require several site visits to complete. • Obtaining reliable as-built infonnation is difficult or not available, • Reviewing the work of contractors for compliance can vary greatly per site and contractor • Site conditions vary. • Number of meters and improvements needed varies Inten/iews were made with three agencies and two engineering firms to obtain historical cost infonnation for these services. Following is a summary of the discussions. Moulton Niguel Water District - Discussions were held with Dave Blythe, Recycled Water Crew Chief. This agency currently sells 7,800 AFY of recycled water at 1075 sites having 1,135 meters. They plan to sell up to 9,800 AFY in their current expansion. They use CGvL Engineers to perfonn retrofit work, which primarily includes retrofits at malls, schools, and HOA sites. For a commercial site the average time billed is 60 hours. The current rate is $58/hour to $62/hour for two cross-connection control specialists. At this rate, the cost is approximately $7,000 per site, which covers onsite testing and inspection only. Additional costs include irrigation site plan preparation and approval through DEH, which adds an additional $5,000. Total cost is aoproximatelv $12.000 per site. City of San Jose - Discussions were held with Eric Hanson, Recycled Water Section, regarding their South Bay Water Recycling system. They contracted with Kennedy-Jenks for "Customer Retrofit Design and Construction" sen/ices for the period March 31, 2001 to December 31, 2003. This work included preparing irrigation retrofit plans, approving them through their local Health Department, and performing onsite testing. Cost proposals for this work were bid based on looking at aerial photos and driving around the area. The cost was budgeted in the amount of $1,852,892, and covered 117 customer use sites. Using this budget, the averaqe cost is $15.837 per site. City of San Diego Water Department - Discussions were held with Hossein Juyberri of San Diego's Recycled Water Section. They contracted with RBF and PBS&J for this work. According to Mr. Juyberri the costs to the City were 28 expensive with a $10.000 minimum charae per site. Hossein has charted the costs, which ranged from $1,000 per acre-foot to $2,000 per acre-foot per site. The City of San Diego has decided not to continue contracting this work out. They are preparing the retrofit irrigation plans using the City's engineering technicians. The onsite testing is perfonned by the City's Cross-connection Control Specialists. At our request we obtained an infonnal quote from CGvL Engineers to perfonn "Customer Retrofit and Design and Construction Services" on an industrial lot. Their quote is shown on Table 7. The approximate cost closely matches the costs listed above at an average of $12,500. Shown below in Exhibit 1 and 2 are their assumptions for the type of work required.

Conclusion on Consultant Costs for Phase II Conversion and Retrofit Connections- Cost for conversions and retrofits in the Phase II project by consultants performing the work are estimated below. On average for conversions at commercial and industrial use sites it was assumed they could be performed for $10,000 per site at today's cost. Some sites may be higher or lower. Since there are 106 conversion sites the cost for contracting this work to consultants is estimated at $1,060,000. For retrofit work, the cost is assumed at $13,000 for each commercial and industrial use site, and $30,000 for City Park and HOA sites. An estimate for 102 retrofit sites is approximately $1,500,000. Total cost to contract with consultants for this work is approximately $2,500,000 A budget of $3,000,000 would need to be established for a consultant to do this work. 34 staffing for Maintenance and Operation of Phase II Facilities CWRF - In this analysis, operation and maintenance of the CWRF is being separated from the distribution system. This decision is based on a proposal to contract the CWRF operation and maintenance work with the Encina Wastewater Authority. If the City were to perform this work, then a Grade V Wastewater Treatment Plant Operator plus a Grade I or Grade 2 Wastewater Treatment Plant Operator would need to be hired by the City to operate and maintain the facility. The City, through its consultant, is preparing operation and maintenance manuals to be used in outlining the work required at the CWRF. With this information an agreement will be prepared with the Encina Wastewater Authority to operate and maintain CWRF. The first full year of operation probably will not occur until FY 05/06. In 2002, the Encina Wastewater Authority made a preliminary estimate of the cost to operate and maintain the CWRF, which is summarized below: 1. Encina Wastewater Authority Labor = $135,706/year 2. Power cost excluding the finish water pumping station = $115,850/year 3. Chemical Cost = $88,985/year. 4. Miscellaneous = $122,995/year Total annual cost for CWRF was estimated at approximately $464,000/year. Distribution System - For the Phase II distribution system, the City's unifonn performance standards were used in preparing a staffing analysis for maintenance and operation. The workload will impact the Water Operations Section, the Cross-Connection Control Section, and the Meter Sen/ice Section. The staffing analysis for the first two sections is presented in two separate memorandums both dated February 19, 2004 and shown at the end of this Chapter. The analysis indicated that the Water Operations Section will need one additional operator and the Cross-Connection Control Section will need three additional cross-connection specialists. The Meter Service Section has seven Meter Sen/ice technicians and one supervisor. Although the addition of the recycled water meters will impact their workload discussions with Kurt Musser indicate that they are proposing to have in place within a year a "remote meter reading program" which will allow more meters to be allocated to each staff position. Recommendation on Required City Staffing for Phase II Recycled Water System The following number of additional personnel are needed to complete construction, and operate and maintain the combined Phase II and Phase I system: 35 Table 11 Public Works Division Current Staffing Additional Staffing Required for Phase II Water Operations Section 6 - Water Operators 1 - Water Operator Meter Service Section 8- Meter Sen/ice Techs. -0- Cross-connection Control Section 3 - Cross Connection Control Specialist 3 - Cross-connection Control Specialist Engineering Department, Design Division 2 - Engineering II Technicians, with AWWA certification as Cross- Connection Control Specialist 2 - Temporary Workers or student workers In the Operations Sections, it will take four to six months to obtain the qualified personnel, and approximately one-year to train them on the required procedures. In the Engineering Department it will take six months to train Engineering Technician II staff and the temporary workers on preparing the required site plans using Auto Cad and site work review. It is recommended that recruitment of these staff positions now begin in order to maintain the connection schedule proposed in this Implementation Plan. 36 February 19, 2004 TO: PUBLIC WORKS MANAGER, UTILITY OPERATIONS FROM: PUBLIC WORKS SUPERVISOR, WATER OPERATIONS Recycled Water Phase II Staffing Projections The Phase II expansion of the recycled water system will impact the following operational Activities - P04 Regulating Valve Maintenance, P06 System Surveillance, POS Pump Station Maintenance, P12 SCADA System Maintenance and Installation, TRG Training and Leave.

ROS - Site Monitoring: We are estimating the addition of at least 365 sites. In addition, sites such as Bressi Ranch and Villages of La Costa are not far enough along in the development process to accurately predict the number of sites each development will generate. Additional Site Monitoring will require approximately 1,993 hours. R04 - 4 Yr. Cross-Connection Tests: Will require an additional 4,211 hours and add 87 units each year. The total number of additional cross-connection tests includes 41 units from Bressi Ranch, which is the minimum number there will be and none from any other projects currently under development. Numbers may vary slightly between the following spreadsheets and the Maintenance Management Reports due to rounded numbers. R06 - Walk Through Inspections: An additional 1,166 acres will be added that require 455 staff hours to inspect. The figures for additional hours required on the worksheets were derived using the existing Maintenance Management Projected SH/Unit of .39 hours per acre. This figure is subject to change depending on the types of use sites and is very conservative for the types of sites that will be coming on line. TRG - Training: Using the current Maintenance Management figure of 95 hours per person, per year an additional 285 hours would be required. Leave: An additional 690 hours of leave would be required. With the exception of Bressi Ranch and Villages of La Costa, figures involving future development have not been included in these estimates.

However, the process of converting or retrofitting a customer's use site to use recycled water in place of potable water has not previously been detailed and it is anticipated that the work effort will require significant coordination and record keeping to be successful. It may also take seven years to complete the connection process and possibly longer depending on the approach used. There are three alternative processes that have been investigated for this project. Each process is described below. Alternative 1 - Perform Retrofit Work by Property Owner The work required at each use site is divided into two main areas engineering and construction. With Alternative 1, it is recommended that the City would perform the engineering aspects and the property owner funds, arranges, and completes construction. Engineering - A City Engineering Technician II or consultant will first determine what retrofit or conversion work needs to be performed by making a site visit with the property owner. The City's staff or consultant will gather the information necessary to prepare a conceptual design of the retrofit. City staff will speak to potential customers about their operations, gather drawings, and visually inspect the proposed recycled water use site. To accelerate the preparation of the site plan. City staff is strongly considering on using a mobile GIS data collection device combined with existing City aerial photos to accurately locate irrigation system attributes and plotting them automatically on the aerial map rather than using hand written notes from the field and preparing site plans using AutoCAD. With this infomnation the City staff will prepare the retrofit site plan of each use site and have it approved through the DEH at the City's expense. Finally, the City either using its staff or a consultant will perform onsite inspection of contractor's work and perform required testing. At completion DEH would witness the shutdown test. Construction - The property owner would construct the necessary retrofit work at their expense in accordance with CMWD Ordinance No. 31 requirements, which states the following in Section 5.1.3: 'Ttie water customer shall be required to submit a plan of implementation to the Carlsbad Municipal Water District's General Manager within ninety (90) days after receipt of notice of preliminary determination. The plan of implementation shall describe in detail how 37 the water customer intends to retrofit his water facilities to use reclaimed water in accordance with all Federal, State and local laws and public health guidelines. ...Carisbad Municipal Water District's General Manager shall have the authority to approve the water customer's plan of imptementation within thirty (30) days after it is submitted to the District. Once approved, the water customer must implement the plan of implementation within one (1) yean If more than one (1) year is required by the water customer to implement the required plan of implementation, an appeal may be made to the Carlsbad Municipal Water District's Water Commission for their recommendations to the Board of Directors by submitting appeal in writing to the General Manger of the District". Based on Section 5.1 of Ordinance No. 31 the connection process will include the following procedures: 1. Preliminary Determination - City determines if a specific property shall be converted from potable irrigation to recycled water irrigation. 2. Notice - City provides written notice by certified mail to water customer of City's preliminary determination. 1. Implementation Plan- Water customer prepares an implementation plan detailing how his property will be converted to recycled water for irrigation, and submits this plan within ninety (90) after City provided written notice of preliminary determination. 2. Approval of Implementation Plan - City must approve implementation plan within thirty (30) days after receiving the implementation plan from water customer. 3. Implementation - Water Customer must complete retrofit work within one (1) year of approval of implementation plan. 4. Appeal - If retrofit work will take longer than one (1) year, then water customer must submit a written appeal within thirty (30) days after receiving any notice of determination to comply by the City. 5. Penalty - Any owner who violates Ordinance 31 is subject to a fine up to $1,000, and water service to the property may be discontinued. To assist property owners, who will be unfamiliar with the work required, the City could provide a list of contractor's familiar with making retrofits and the City's process for final acceptance. The "contractor list" would be for information only and not a recommendation of any contractor. Alternative 2 - Incentive Program This is similar to Alternative 1 except in lieu of discontinuing water service an increased penalty is added to the customer's potable water billing for non- compliance until the required work is completed, and a City loan option would be included to assist property owners in paying for the work. The City would fund and perform the engineering work. Engineering - Refer to description above for Alternative 1. 38 Construction - Construction would be the responsibility of the property owner. However, Ordinance No. 31 would be revised to delete the penalty of discontinuing potable water service for noncompliance, and in its place add a 50 percent surcharge onto the customer's potable water billing until the retrofit or conversion has been completed. As an example, the following paragraph could be added to Ordinance No. 31. "Where recycled water is available in offsite facilities, if after one hundred and eighty (180) calendar days from the date of the CMWD's final detemiination under Section 5.1.3 the prospective user has not completed required onsite retrofit or conversion work, then in addition to those penalties set forth in Section 7, the CMWD shall impose a surcharge equal to fifty percent (50%) of its potable water rate in effect at the time of violation, such surcharge to be included in the customer's monthly billing." Through a separate resolution, an optional low-interest loan could also be made available by the City to fund the retrofit or conversion, which would be paid back within five years. An agreement could be made with the customer for this loan funding. Loans are not to exceed $2,500 per irrigated acre. To provide financial assistance to the property owner the following process could be implemented: 1. Customer requests loan information from City's Engineering Technician II. 2. Customer contacts City for agreement 3. City mails agreement documents to customer 6. City's Engineering Technician II provides account number, user site number, irrigated acreage if available and site location. 7. Customer retums information regarding name, address, contact, etc. to City. 8. Agreement information completed by City and sent to customer for execution 9. City staff approves itemized invoice for retrofit work for each service and submits amount for City records. 10. Executed agreement approved by City Council 11. Approved agreement sent to customer, copy to engineering files and field inspector notified. 12. City field inspector notifies Finance Department of service status change to recycled water. 13. City issues check request and loan agreement copy to Finance Department and Finance mails check to customer 14. Finance begins loan repayment billing 15. Once the required loan repayment is completed the customer-billing rate is reduced to the recycled water rate. 39 Alternative 3 - All Work Funded by City This process has the retrofit or conversion perfonned by contractors under contract with the City. Engineering - Refer to the description above for Alternative 1. Construction - There are four options to construct the required improvements. Optioni: The City would first obtain a "right of entry" from all property owners. The City would then obtain bids from contractors to perfonn the work, by supplying them the retrofit or conversion plans approved by DEH and obtaining bids to perform the work. A bid option may include awarding the work based on time and material rather than a total contract bid with change order allowance. The Rincon Del Diablo Municipal Water District used this approach and they found that the work was significantly less than the bid price. Because of the complexity and unknowns at each site contractors bidding the work was found to result in high bids. The time and material approach removed the uncertainty out of the work effort. The agency's cross-connection control specialist staff perfonned the inspection. Option 2: To avoid excesses by contractors bidding this type of work, the construction could be separated into three Phases. Phase I would be awarded to one contractor and Phase 2 could be awarded to another contractor. Whichever contractor completes the work quickest and with the fewest problems and customer complaints would receive Phase 3. Rincon Del Diablo Municipal Water District used this approach, and performed retrofits at 72 sites in four months time. Option 3: Construction is bid based on work required for 20 to 25 retrofits and 25 conversions per year (a total of 50 use sites per year). The construction schedule for onsite work at this rate meets the MWD target yield goals. Option 4: The City could also perfonn the construction work using its own staff. An Engineering Technician II would be assigned two or three construction laborers who would be hired as temporary workers. The construction laborers would perfomn the work on a continuous basis proceeding from site to site as plans are approved by DEH. This is the lowest cost approach because profit, overhead and bonds are eliminated. 40 Potential Expense of Retrofit and Conversion Alternatives An estimate has been made of the potential construction costs involved in the retrofit and conversion process at a typical industrial building site. These costs are listed below in Tables 12 and 13. PBS&J Engineers has provided a cost estimate for a park site that could also be extrapolated to an HOA site (see Table 14). The approximate total cost for each of the three alternative connection approaches is shown in Table 15. To better understand the type of improvements that a contractor makes, pictures were taken at retrofit sites in Rincon Del Diablo Municipal Water District, which just completed this type of work in 2003 through the use of two contractors. These pictures are shown following Table 15. 41 ^ble 12 OPINION OF PROBABLE COST FOR CONVERSION OF AVERAGE INDUSTRIAL USE SITE Line Description Quantity Material Cost Labor Cost Total Cost Line Description Quantity Unit Cost Total Mat.

The connections may not occur in the time frame outlined in the MWD agreement with CMWD. Explaining potential costs to perfonn the work may cause property owners to pursue an exemption. The City may be forced to shut off the potable water supply to irrigation meters in order to encourage the property owner to comply. The property owner is going to be inexperienced with how to proceed with the retrofit or conversion process. Contractors may take advantage of the situation to perfonn more work than is necessary. City may not accept the work completed requiring the property owner to have the contractor return to make required improvements. Obtaining signed user agreements may be difficult to obtain. Property owners are anticipated to throw up every excuse on why they should not do the work resulting in many petitions to the City Council for exceptions. • The City will need to chart the progress of each property owner separately rather than being able to combine multiple use sites into cost effective bid groupings. Alternative 2: • The potable water rate increase of 150 percent will probably be needed to encourage compliance with the connection schedule for most property owners. This situation has been encountered by Moulton Niguel Water District. • The connections may not occur in the time frame outlined in the MWD agreement with CMWD. • The property owner is going to be inexperienced with how to proceed with the retrofit or conversion process. • The City will need to chart the progress of each property owner separately rather than combining multiple use sites into cost effective bid groupings. • The time frame for construction may not coincide with the MWD agreement conditions. • Contractors may take advantage of the situation to perfonn more work than is necessary. • City may not accept the work completed requiring the property owner to have the contractor return to make required improvements. 57 • Property owners are anticipated to throw up every excuse on why they should not do the work resulting in many petitions to the City Council for exceptions. • If consultants were used to perform the engineering activities rather than using City staff a budget of $3,000,000 would be needed for consultant work alone. • Moulton Niguel Water District uses this approach and they indicate that it takes many more years to have property owners proceed with the work. Alternative 3: • The City can coordinate with contractors directly to perform the retrofits and conversions at the City's schedule to meet MWD agreement requirements. • The City can schedule retrofit and conversion work into cost-effective groupings to reduce mobilization demobilization downtime between use sites that are at contiguous locations. • This has the highest cost to the City because of the need to pay for the onsite work. However, Rincon Del Diablo Water District was able to perform 72 use sites for $180,000 using a time and material approach. • Construction cost would be budgeted at $1,800,000. • If consultants were used to perform the engineering activities rather than using City staff a budget of $3,000,000 would be needed for consultant work alone. Using a consultant is not recommended at this time. Recommendation It is recommended that Alternative No. 3 be used in processing this work. Alternative No. 3 offers the most control on the connection process and time schedule. It relieves property owners of the burden of determining how to make the conversion or retrofit. It allows the quickest time to begin collecting revenue from monthly billings to pay back low-interest loans from the State Water Resources Control Board. It reduces the amount of accounting work by the City in tracking the status of each use site (i.e. less correspondence between property owners and the City). The contractors should be selected based on bidding large groupings of use site conversions and retrofits (e.g. 50 use sites). Awarding the contract on a time and material basis may reduce the total cost as experienced by Rincon Del Diablo Municipal Water District. In using Alternative 3, it is further recommended that the City's Engineering staff be used to perform the Engineering aspects rather contracting this work out. In the initial year it is recommended that an experienced consultant be used to provide additional training on what to look for in the field and how to handle issues with contractors. Using consultants to perform all tasks would require approximately $3,000,000 in a contract to complete the work. The additional expense compared to City staff is significant and is not presently budgeted. However, a consultant can be programmed as back up or for training of City staff if the Engineering Department cannot accommodate the workload. Additionally, Alternative 3 allows the City to maintain continuity, momentum, and 58 accountability. These three issues are important because it completes the work in a timely manner at the least cost and provides the most amount of knowledge on what occurred in the field at each use site. It enables staff to be able to answer any question with property owners and they would also be able to respond to any question regarding Vhy the process is not moving ahead as scheduled." With City staff performing the work we know what the problems are and can address issues as they occur. The City can fund the construction cost and DEH fees using a portion of the $6 million the City Council appropriated for water resources in 1998.This appropriation was placed into the water replacement fund. It is recommended that the funding required be obtained from the Recycled Water Account (502) through a loan from the Water Replacement Fund. This will enable the Finance Department to track actual expenses for use of recycled water. 59 Retrofits Page 1 of2 Environmental Service: CITY ov Si\h }i ISl -i \l'll.\l tlf SIIK.O.N V.\I IM Services fon ;:Aiioiifc'S0ii'Je§@': Recycling Dunking V^astewater Wdter & G.trb^qs Water TisatPi?nt Corstnv-it'.on Resi ci ents Businesses Schools Water Pollution Pre\<enti3n Ndtur^l & Energy Resources Search ESD Fe«db3ck Retrofits for Recycled Water Sites that are large water users and located near the South Bay Water Recycling (SBWR) pipeline system are being contacted to utilize recycled water to irrigate crops, and for landscaping, golf courses and parks, as well as for industrial processing. The 60-mile pipeline will deliver up to 21 million gallons of recycled water per day in the cities of Santa Clara, Milpitas and San Jose for non-drinking purposes. Water recycling has numerous benefits. It will save you money because it costs up to 30% less than potable water. Recycled water is purified from wastewater, so the supply is drought-proof and virtually unlimited. Our water has been endorsed by the Santa Clara County Medical Association. Using recycled water saves limited potable water supplies for domestic purposes. Retrofit Your Site At No Cost To You South Bay Water Recycling will provide design and construction for the irrigation retrofits at your site, all at no cost to you. Our staff will fully coordinate with you throughout the process and make it as simple as possible. Here's how to get connected! "No-w, not only have we identified a drought-proof source of water, but we anticipate a reduction in our water bill." - Jim Opdenbrouw, General Electric Its Easy To Get Connected Step 1: Contact your SBWR representative at (408) 945-5185 for more details. Step 2: Approve and sign the Right of Entry Form. Step 3: Coordinate water shutoff. Step 4: Attend SBWR Site Supervisor Training. Step 5: Reap the benefits of recycled water, and start saving on your water bill. Questions & Answers Why should I retrofit now? If you retrofit now, you can begin saving on your water bill immediately. If you don't retrofit now, you may have to pay your own retrofit costs later. So act now! How is this latest offer different from those in the past? In the past, SBWR has offered money in the form of water credits for you to construct your own retrofits. This new offer shoulders all of the responsibility and cost. SBWR designs it, builds it, and pays for it. All you need to do is agree to participate. Is it true that the use of recycled water can be mandated? If SBWR does not reach a diversion goal of 15 million gallons per day, a moratorium on sewer hookups may be implemented which would halt all construction in the Santa Clara Valley. In the future, the use of recycled water for irrigation and industrial processes may be mandated. http://www.ci.san-jose.ca.us/sbwr/Retrofits.htm 07/17/2003 Retrofits Page 2 of 2 Why was my site chosen to receive recycled water? Your site is located within a specified area of the main SBWR pipeline and has been targeted as a large water user. Is recycled water being used elsewhere and what have the results been?

A certified AWWA Cross-Connection Specialist must perform the test. Click here for a list of certified specialists. First part of the test: 1. The potable water system shall be activated and pressurized. The recycled water irrigation system shall be shut down at its point of connection and depressurized. This is usually done by manually bleeding an irrigation control valve and/or quick-coupling valve that is located at the lowest point of elevation in the irrigation system. 2. The potable water system shall remain pressurized for a minimum period of time specified by the Cross-Connection Control Specialist while the irrigation system is depressurized. The minimum period of time the recycled water irrigation system is to remain depressurized shall be determined on a case by case basis, taking into account the size and complexity of the potable water and recycled water irrigation systems, but in no case shall that period be less than one (1) hour. 3. All recycled water irrigation control valves and quick-coupling valves, and any site features that are approved to be supplied with recycled water from the on-site irngation system (such as decorative fountains) shall be tested and inspected for flow. Continuous flow from any part ofthe recycled water system-irrigation system or decorative fountains, etc.-indicates a cross-connection. 4. All potable water fixtures (interior and exterior)-faucets, hose bibs, drinking fountains, toilets and urinals, supply lines to decorative fountains, etc.-shall be tested and inspected for flow. No flow from any potable water outlet indicates that it may be connected to the recycled water irngation system. 5. If no cross-connections are discovered, proceed to the second part of the test. If any cross-connections are found, they must be disconnected, and the site must be retested by an AWWA Cross-Connection Specialist per these procedures. Second part of the test: 1. The potable water system shall be shut down at its point of connection (usually the meter) and completely drained-usually at its drain valve or at the reduced pressure principle backflow device. 2. The recycled water irrigation system shall then be activated and pressurized. 3. The recycled water irrigation system shall remain pressurized for a minimum period of time specified by the Cross-Connection Control Specialist while the potable water http://www.ci.san-jose.ca.us/sbwr/CrossConTest.htm 07/17/2003 Cross Connection Testing p^gg 2 of 2 system is depressurized. The minimum period of time the potable water system is to remain depressurized shall be determined on a case by case basis, but in no case shall that period be less than one (1) hour. 4. All potable water fixtures (interior and exterior)-faucets, hose bibs, drinking fountains, toilets and urinals, supply lines to decorative fountains, etc.-shall be tested and inspected for flow. Some flow may occur from water breaking loose from an air lock in an overhead water line. The amount of flow to cause a concern is a judgment call by the Cross-Connection Specialist. Continuous flow from any part of the potable water system (that is beyond the drainage generated by an air lock breaking free) indicates a cross-connection. 5. All recycled water irrigation control valves and quick-coupling valves, and any other site features that are approved to be supplied with recycled water from the on-site irrigation system (such as supply lines to decorative fountains) shall be tested and inspected for flow. No fiow from a recycled water irrigation control valve, quick- coupling valve, or any other recycled water fixture indicates that it may be connected to the potable water system. 6. If no cross-connections are discovered, then the potable water system shall be re- pressurized. If any cross-connections are found, they must be disconnected, and the site must be retested by an AWWA Cross-Connection Specialist per these procedures. 7. The certified AWWA Cross-Connection Specialist responsible for completing the above test must indicate the results on a SBWR Cross-Connection Certification Form.

Updated 7-9-03 http://www.ci.san-jose.ca.us/sbwr/WaterRates.htm 07/17/2003 CHAPTER 8 COMMUNITY OUTREACH PROGRAM strategy The strategy of the Public Outreach Program is to educate and build the trust of the public, and customers impacted by the Phase II project conversion and retrofit process and use of recycled water. It is desired that Carlsbad's recycled water program develop a positive identity (brand identity). The program is designed to provide information and feedback addressing six elements: 1. Explain the problem that recycled water solves 2. Describe other alternatives that the City investigated to solve its problem 3. Discuss perceptions of risk and negative connotations 4. Respond to construction related impacts 5. Explain the retrofit and conversion process 6. Explain the proper way for landscape maintenance people to work with recycled water It is important that these elements relate to customers and every dialog about value center around the first three elements listed above. It may be useful to incorporate public health professionals to provide testimonials in drafting up the language for information regarding recycled water. The public or audience would include "middle school" age children through adults, plus residents and businesses. Key Messages The key messages to present at meetings and include in written infomnation material are: Future imported water supplies are being challenged Water shortages and rationing in San Diego County and Carlsbad may occur unless new water sources are developed Recycled water provides a reliable drought-proof supply to an arid area Recycled Water is reliable and drought proof Recycled water produces less energy than importing water Water Industry is entering a new era where reuse, efficiency, etc. is more important Recycled Water is Safe, but is not for drinking Landscape maintenance staffs need some training on proper handling of recycled water to eliminate cross connections and general heath concerns. Messages must address health and safety, use simple terms because jargon may imply you're hiding something, and testimonials from outsiders (could be 60 very important). Written information and presentations at meetings will be prepared to deal with opposing viewpoints. Following are the recommended components on the public outreach program: Public Meetings - Conduct at least three public meetings especially for the industrial park areas and HOA's. At these meetings the purpose, development and benefits of the Phase II Project will be reviewed, and safety issues and landscape maintenance staff training regarding its use will be presented. The treatment and water quality will be described. The connection schedule will be presented. Customers are to be given the opportunity to ask questions about recycled water and get an update on the progress of the Phase II project. Retrofit Process Meetings - These meetings serve three purposes. First, potential retrofit and conversion customers (208 total) will be briefed on the benefits and safety of recycled water and on the details of the Phase II Project. Potential customers are to be given the opportunity to ask questions and express their interest in using recycled water. Second, the meetings allow City staff to gather the information necessary to prepare a conceptual design of the retrofit. City staff will speak to potential customers about their operations, gather drawings, and visually inspect the proposed recycled water use site. These meetings also provide an opportunity for the City to explain the retrofit process to customers. It can be used to issue a "Customer Retrofit Guidebook." Which is explained below. Customers are given the opportunity to ask questions about recycled water and get an update on the progress of the projects. Prepare displays - These displays are envisioned to be large self-interpreting information storyboards on the Phase II project and the retrofit process. They will be semi-permanent. They will be durable for use during public meetings, during presentations to the Citizens Academy and to have for continuous viewing at City Hall, the Faraday Building entry area, the Operations Building entry, the entry at the Carlsbad Water Recycling Facility, and both City Libraries. Prepare Project Brocliures - These shall be suitable for handouts at public meetings and placed next to the semi-permanent displays located throughout the City. Information shall provide a simplified treatment process drawing, current pictures of existing recycled water use sites and purple color piping and signs, discuss purpose of making retrofits and general steps in the retrofit process, and contact information. Some preliminary examples are shown at the end of this chapter. Customer Retrofit Guidebool( - The major work involved in performing retrofits will be contained in this guidebook to assist potential customers with a written description on the steps to complete the onsite retrofit work. 61 Information Hotline - This shall be used to field questions during construction and also during the retrofit and conversion process. Initially monitored by Katz and Associates under contract the telephone number has been established at (760) 325-8784. Project Information Card - This card is issued to the construction inspectors who hand them out to the general public. This card briefly explains the purpose of the project. The card has already been created and is shown at the end of this Chapter. Illuminated Message Board Signs - These will be used to announce the beginning of construction, and potential road impacts or traffic delays. These will be placed at selected street locations after discussion with the City's assigned inspector and the contractor. PowerPoint Presentation - This would be infonnation prepared for the Engineering Department and Cross-Connection Control Section and used in making presentations at public meetings and to landscape maintenance personnel. An example is shown at the end of this chapter. Video Presentation - This will be used at public meetings, presentations to middle school students, and to assist in training landscape maintenance staff in handling recycled water. We will attempt to use City staff in the production of this video with the assistance of an outside consultant on its content and message. This video could also be shown on local cable television channels made available to the City. Treatment Facility Tours - Provide tours of the new Carlsbad Water Recycling Facility in concert with the Encina Water Pollution Control Facility. Tours could be handled by EWA staff or trained City staff. Direct Mail - Submit letters to HOA and commercial and industrial owners on project impacts. Enclose updated infonnation periodically in monthly water billings. The City's engineering staff would prepare these. City Web site - Have a homepage prepared, which discusses the Phase II project status and infonnation concerning recycled water and the retrofit process. The information on construction would be updated. Citizens Academy - Provide a display, written material, and someone to answer questions during the twice a year citizens academy. Implementation The community outreach program has been started. We have begun preparation of display material, a recycled water infonnation brochure, and PowerPoint 62 Presentation. We have completed "project information cards" as handouts for inspectors, moved in message board signs to construction areas, provided information to "Worth Noting". In the near future we will be updating the City's web site. Finally, we will be utilizing the City's Communications Team for comments and suggested improvements on our message, theme and assistance in developing a brand identity for the recycled water supply. 63 Recycled Water Pipeline Project ^ P™|eC.„,on««io„U„e: 1 V(760) 325-8784 Deputy City Engineer — Inspection Division City of Carisbad 5950 El Camino Real, Carlsbad, CA 92008 The City of Carlsbad is expanding its recycled water system to supply irrigation water. The recycled water will be safe for human contact and will be used for landscape irrigation at parks, schools, golf courses, greenbelts, commercial businesses and the common areas of homeowner associations. This project will support our community's efforts in conserving and increasing our current water supply and will increase the reliability of the water supply. The recycled water project includes pipelines and associated infrastructure for distributing recycled water. ~*yTjiiw ••as-v ---- ' in a nutshell i e entire community benefits when recycling helps conserve our drinking water I Qler oilobilily In Southern California water - the source of life - refreshes, cleanses and sustains our quality of life, in what often would be an arid environment. It's required for residences, agriculture, and industry. And yet only 2.6% ofthe earth's water supply is fresh. Uloler Supply In Southern California, 30% of the water used is being imported from the Northern part of the State, and the Colorado River supplies about 60% of annual usage. Seven states are dependent on the Colorado River, which leads to disagreements in allocation, toxin clean up and unforseen problems. Historically California has used more water than its entitlement, which was possible by reallocation of unused water from Arizona and Nevada's entitlements. Recently, because of rapid growth of the neighboring states, there has not been enough unused water to meet California's demand. According to predictions, the Golden State's demand for water will continue, but access to Colorado River water is limited by California's water entitlement as well as by capacity of the delivery system. Being dependent on imported water, it is 26 countries have more people than their water supply can adequately support essential that we all learn to use it more wisely by giving it a second chance. hot is cycled Ulciter The California Water Code defines recycled water as "water which, as a result of treatment of waste is suitable for a direct beneficial use or a controlled use that otherwise would not occur." And one of the common forms of pollution control in the United States is wastewater treatment. It utilizes basic physical, biological and chemical principles occurring naturally in a lake or stream, just at a higher speed. Today's population and volume of domestic and industrial wastewater require communities such as Carlsbad to give nature a helping hand. Tk'eQlmenl System Water is treated through an efficient, effective and well-established treatment process to produce recycled water. The incoming wastewater undergoes three treatment levels: primary, secondary and tertiary. Primary treatment uses sedimentation tanks to remove solid pollutants. D uring secondary treatment the effluent from the primary process is treated with beneficial micro-organisms to eliminate organic solids. This is followed by tertiary treatment whereby pathogens and fine suspended solids are removed through filtration and disinfection. Corlsbod's Uloler Aecycling Process Residential and industrial wastewater is pumped into the treatment plant Large debris are removed Heavy debns settle lo the bottom of the tank and are removed Floatir>g material and grease is removed by skimmer Suspended solids heavier than water settle to the bottom and are processed for compost fertilizer or hauled to remote site land disposal Waste water is mixed with oxygen causing bactena to decompose organic pollutants Remaining tiny particles are removed Chemicals cause the remaining suspended malerials to form small masses Recycled water and grannual media is held until fitters remove the disinfection remaining is complete waste _______ Fulty treated STORAwc recycled water TANKS [?a<^X:*9^ beneficial use Seporotion of Systems Today more than one billion people lack adequate access to clean drinking ater Standard practice requires separate piping for potable and recycled water to eliminate potential cross- connection. The 1994 Uniform Plumbing Code, Appendix J requires buried recycled water lines to be separated from potable lines by 10- foot horizontal and I -foot vertical distance. -.>* Houi is Using Recycled Uloter Different While recycled water is a highly treated product, it is not suitable for drinking. Therefore, conditions for use have been established. Recycled water customers must post informational signs, mark sprinkler heads, valving, and other appurtances, and ensure that there are no cross-connection between the potable and recycled water systems. Purple is the color that signifies a system is designed for recycled water use. Irrigation with recycled water scheduled between the hours of 10:00 p.m. and 6:00 a.m. minimizes misting and evaporation and lessens pubiic contact. There are periodic inspections by the City of Carlsbad and the County Health Department to ensure that all regulations are being complied with. Cncino Bosin iter Aeclomotion Progrom A s more recycled water projects come on-line , more recycled water will be available. Common areas of many homeowner's associations as well as a lot of commercial and industrial sites has been designated for retrofitting. Within the next three to five years, the amount of recycled water available to the public will increase by approximately 6 million gallons per day. Current program, when completed, will include: a new advanced tertiary treatment facility, transmission and distribution system of 24 miles of pipelines ranging from 4-inch to 30-inch in diameter, 3 new pump stations, and improvements to the existing Mahr Reservoir. Benefits A dvantages to recycled water use fall into financial and aesthetic categories and include: • Reliable water supply not affected by drought • Nutrients in recycled water lower need for fertilizers • During retrofit process irrigation systems are upgraded: u Leaks and breaks discovered and eliminated u Water-efficient sprinkler heads installed • Controllers or clocks installed and/or upgraded A mong many sites irrigated with recycled water (golf courses, hotel sites, parks, school campuses), the most recognized sites being supplied with recycled water are: • Legoland of California • Four Seasons Resort of Aviara • World-renowned Flower Fields • 1-5 Freeway landscaping Wa cloimed ter Rote The rate charged for reclaimed water was established by resolution of the Board of Directors and is at 5% discount comparing to potable water. Other Cosy Uloys to Conserve Uloter • Adjust your watering schedule to the season. • Always water during the early morning hours to minimize evaporation. • Choose low water use trees, shrubs and groundcovers. • Run your washing machine and dishwasher only when they are full. • Check for dripping faucets and leaking toilets. • Install covers on pools and spas to avoid evaporation. • Install low-volume toilets and make sure there are aerators on all your faucets. For many communities, including Carlsbad, an investment in recycled water solves many problems. It forestalls a severe water shortage and provides drought protection. It offsets the need to purchase additional water from an external supplier. Water recycling extends our drinking water supply, allows the community's investment in water to work right at home, creates jobs, and provides cost effective, environmentally acceptable alternative to imported water. 1636 Faraday Avenue Carlsbad.CA 92008 For information: 1-760-602-7503 Water Recycling Presented by: ^^^^ What is Recycled Water?

Metropolitan, Authority, and Carlsbad may be collectively referred to as "Parties" and individually as "Party". RECITALS A. There is now in effect a Local Resources Program Conversion Agreement (Conversion Agreement) dated July 1,1999 by and among the Parties for the development and utilization of recycled water, which provides for the Encina Basin Water Reclamation Project - Phase I (Phase I Project); B. Pursuant to the Conversion Agreement, the Phase I Project commenced operations in January 1993 and is capable of meeting an annual demand of 2,050 acre-feet of Recycled Water for non-potable landscape, agricultural, commercial, and industrial purposes; C. Metropolitan's Board of Directors, at its June 9,1998 meeting, established terms and conditions for the LRP and authorized staff to issue a Request for Proposals (RFP) targeting 53,000 acre-feet per year (AFY) of needed local resource production by the year 2010 from cost-effective projects that would help contribute to the region's overall water supply reliability; D. In response to the RFP, Carlsbad submitted a project proposal for the 2,950 AFY Encina Basin Water Reclamation Project - Phase II (Phase II Project) that was competitively evaluated by a review committee and subsequently identified as one of 14 projects recommended for inclusion in the LRP to achieve the targeted production; E. The Parties mutually agree to terminate the Conversion Agreement, referenced in Paragraph A above, effective July 1,2000; F. This Agreement combines both Phases I and II of the Encina Basin Water Reclamation Project; -j- MWD Agreement No. 23300 G. Metropolitan was incorporated under the Metropolitan Water District Act (Act) for the purpose of developing, storing, and distributing water for domestic and municipal purposes; H. The Act empowers Metropolitan to acquire water and water rights within or without the state; develop, store and transport water; provide, sell and deliver water at wholesale for municipal and domestic uses and purposes; set the rates for water; and acquire, construct, operate and maintain any and all works, facilities, improvements and property necessary or convenient to the exercise of the powers granted by the Act; I. Authority, as a member public agency of Metropolitan under the Act, is a wholesale purchaser within its service area of water developed, stored, and distributed by Metropolitan; J. Carlsbad is a member public agency of Authority and provides domestic and nondomestic water services entirely within Authority's service area; K. Carlsbad is empowered under Section 71309 of the Water Code to enter into contracts necessary to carry out its powers and purposes; L. Metropolitan's water supply and demand projections for its service area, including that encompassed by Authority, show that additional sources of supplemental water must be developed to meet future needs; M. Metropolitan has determined to take all necessary steps to provide its service area with adequate and reliable supplies of high quality water in the years ahead in an environmentally and economically responsible way, including providing financial incentives to water recycling projects under its Local Resources Program (LRP); N. Metropolitan and Authority have determined that it is mutually beneficial for local water projects originating in Authority's service area to be developed as a supplement to Metropolitan's imported water supplies in order to meet future water needs; O. A significant amount of treated wastewater generated within Authority's service area is currently discharged to the ocean, which water when provided with tertiary treatment could be used for non-potable purposes; P. Additional quantities of recycled water could be produced, distributed, and sold by Carlsbad by means of additional capital facilities to treat, distribute and use additional wastewater, thereby avoiding disposal thereof as a waste product and reducing the need for additional water that otherwise must be delivered from Metropolitan's imported water supply system for landscape irrigation purposes; -4- MWD Agreement No. 23300 Q. Carlsbad is currently planning and desires to construct additional capital facilities collectively known as the Phase II Project, to treat and distribute, for beneficial use, additional treated wastewater, which will minimize present and future disposal of wastewater as a waste product from Carlsbad, in a manner cost-effective for its customers; R. Metropolitan, in accordance with its LRP, desires to assist Carlsbad in the cost of treating and distributing recycled water for landscape irrigation purposes; S. Carlsbad desires to comply with the provisions of Metropolitan's LRP in retum for Metropolitan's financial assistance for the Project; T. Metropolitan desires to assist in increasing production and distribution of recycled water by providing financial incentives to Carlsbad, through Authority, for implementation of the Project. U. Authority desires to participate in and affirmatively supports the Project by transferring to Carlsbad the financial incentives that it receives from Metropolitan; V. The Parties believe that treatment and distribution of recycled water from the Project will benefit the local community within Carlsbad and the region served by Metropolitan; W. The Project, when fully developed, is estimated as being capable of delivering 5,000 acre- feet per year of recycled water by treating secondary wastewater and distributing recycled water for landscape irrigation purposes.

Under the Project, approximately 5,000 acre-feet per year (AFY) is delivered to Carlsbad Recycled Water customers for landscape, agricultural, commercial and industrial purposes. The Project is located entirely within Carlsbad's service area immediately south of Palomar Airport Road and west of El Camino Real (see Figure 1). Sources of Recycled Water 1. Meadowlark Water Reclamation Facility Under Phase I, the Project currently receives Recycled Water from two extemal sources. The majority ofthe Project's water needs are supplied by the Meadowlark Water Reclamation Facility (Meadowlark), which is owned and operated by Vallecitos Water Distiict (Vallecitos). Meadowlark provides primary, secondary and tertiary freatment to wastewater and has a current capacity of about 2 million gallons per day. Recycled Water from Meadowlark is delivered to the Project through Vallecitos' fail-safe pipeline. Recycled Water in the fail-safe pipeline which is not used by the Project is delivered to the Encina Water Pollution Confrol Facility (Encina) and then discharged to the ocean. Carlsbad has entered into an agreement with Vallecitos to purchase up to 2,040 AFY from Meadowlark. Meadowlark, the Mahr Reservoir and Vallecitos' fail-safe pipeline are pre-existing and not part ofthe Project. 2. Gafner Water Reclamation Plant The second source of Phase I Recycled Water is the Gafner Water Reclamation Plant (Gafner), which is owned and operated by Leucadia County Water District (Leucadia). Gather provides primary, secondary and tertiary treatment and has a current capacity of about 0.75 million gallons per day. Raw wastewater can also be sent to Encina via a separate pipeline from Gafner. At Leucadia's discretion, secondary treated wastewater can be pumped back from Encina to Gafner for tertiary treatment. Carlsbad has entered into a take-or-pay agreement with Leucadia to purchase a minimum of 394 AFY from Gafner for Recycled Water deliveries supplied only to La Costa South Golf Course. Gafner and Encina are pre-existing and not part ofthe Project. -12- MWD Agreement No. 23300 3. Carlsbad Water Recycling Facility Included in the development of Phase II facilities is constraction ofthe proposed 5 million gallons per day Carlsbad Water Recycling Facility (CWRF). CWRF will provide tertiary treatment of secondary effluent from Encina and serve Recycled Water to the Project. Additional facilities may include microfiltration and reverse osmosis to reduce total dissolved solids levels in Recycled Water. Project Facilities Phase I Phase I ofthe Project consists of a distribution system, conversion of two potable water reservoirs to Recycled Water reservoirs and installation of potable water pipelines to replace pipelines for Recycled Water use. The distribution system includes about six miles of Recycled Water pipeline, pumping facilities, and a one-mile pipeline to replace the existing potable water pipeline that will be converted for Recycled Water use. Both the La Costa North and South Golf Course receive Recycled Water from the Project via existing, non-project pipelines. In addition, the Project includes capital improvements to Meadowlark including modifications to the effluent pump station, constraction of a diversion stracture, and installation of electrical and instramentation equipment. Phase II Phase II of the Project will involve constraction of tiie 5 million gallons per day CWRF, extension ofthe existing Recycled Water distribution system by approximately 75,000 feet to serve new users, constraction of a new pump station, and conversion ofthe existing Mahr Reservoir for Recycled Water storage. Although capital improvements to convert the existing Mahr Reservoir from potable to Recycled Water use are included in the Project, the Mahr Reservoir is considered pre-existing and not part ofthe Project. End Users Recycled Water from the Project will be produced for non-potable landscape and agricultural irrigation, and commercial and industrial purposes within Carlsbad's service area. Points of Coimection Project facilities shall terminate at the points of connection to the Project's sources of supply, brine disposal facilities, Mahr Reservoir, the potable disfribution systems, sewer systems, storm drains, groundwater extraction systems, Vallecitos' fail-safe pipeline, and meter connections to End Users. -13- MWD Agreement No. 23300 PROPOSED PUMP STATION PROPOSED PUMP STATION 1 T Pacific Ocean GAFNER-\/ WATER X RECLAMATION FACILITY / A MEADOWLARK ^ WATER / RECLAMATION/ FACILITY MAHR- RESERVOIR 7 EXISTING PIPELINES (PHASE I) PROPOSED PIPEPLINES (PHASE II) Figure 1 ENCINA BASIN WATER RECLAMATION PROJECT PHASE I & li EXHIBIT B LRP CONTRIBUTION SCHEDULE Maximum Annual LRP Contribution Allowable Yield' Fiscal Year ($/AF) (AF) 2000-01 210 2,250 2001-02 210 2,550 2002-03 210 3,050 2003-04 210 3,450 2004-05 200 3,850 2005-06 200 4,250 2006-07 200 4,650 2007-08 200 4,950 2008-09 200 5,000 2009-10 139 5,000 2010-11 100 5,000 2011-12 100 5,000 2012-13 100 5,000 2013-14 100 5,000 2014-15 . - . 100 5,000 2015-16 100 5,000 2016-17 100 5,000 2017-18 100 4,150" 2018-19 100 2,950"* * - Subj ect to reduction pro visions outlined in Exhibit C.

EXHIBIT C PERFORMANCE PROVISIONS 1. The following performance provisions apply: a. The Agreement will terminate if constraction of Phase II facilities has not commenced by April 1, 2002. If this Agreement is terminated under this provision, the Conversion Agreement shall be restored to full force and effect. There is no established appeal process for this outcome. b. The Agreement will terminate if Project production is not delivered from the proposed 5 million gallons per day CWRF by April 1,2006. If this Agreement is terminated imder this provision, the Conversion Agreement shall be restored to full force and effect. The Project sponsor(s) may appeal this decision to Mefropolitan's Board of Directors. c. If Phase II production from the CWRF during Fiscal Years 2004-05 through 2007-08 does not reach the target yield of 1,092 acre-feet (AF), Mefropolitan will reduce the Allowable Yield outlined in Exhibit B. The reduction shall be one-half the shortfall between the targeted yield and the highest Phase II production in that period. For example, the Phase II Ultimate Yield of the Project for the following performance will be revised from 2,950 to 2,879 AFY for Scenario 1 beginning in Fiscal Year 2008-09. There would be no adjustment under Scenario 2.

Scenario 2: FY 2012-13 Allowable Yield = 5,000 AF Shortfall = 0.5 x (1,858 - 1,600) = 129 AF The Allowable Yield for Fiscal Years 2012-13 through 2018-19 outlined in Exhibit B, will be reduced by 129 AF. e. If Phase II production from the CWRF during Fiscal Years 2012-13 through 2015-16 does not reach the target yield of 2,212 AF (or revised Allowable Yield if applicable), Mefropolitan will reduce the Allowable Yield (or revised Allowable Yield if applicable) outlined in Exhibit B. The reduction shall be one-half the shortfall between the targeted yield and the highest Phase II production in that period. The adjustment will be made using the same methodology shown in the above examples. If Phase II production from the CWRF reaches 2,950 AF in any one Fiscal Year, there will be no adjustment to the Allowable Yield thereafter. o:\clustrl0\inmshared\contract\agree\23300 -17- MWD Agreement No. 23300 MWD METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA Oflice of the Gefieral Manager j^^^CB-l^^^ May 15, 2001 ^^ 2001 Mr. Robert Greaney ENQINEERI'^G General Manager pgp/VRTMENT Carlsbad Municipal Water District 5950 El Camino Real Carlsbad, California 92008 Dear Mr. Greaney: Commencement of Construction for Encina Basin Water Reclamation Program - Phase 2 On March 28, 2000, Metropolitan, San Diego County Water Authority, and Carlsbad Municipal Water District entered into a Local Resources Program Agreement for development of the Encina Basin Water Reclamation Program Phase 1 and 2 (Agreement No; 23300).

We have a long and successful history of working with the City of Carlsbad's water reclamation program and conversely greatly appreciate your support of our recycled water regulatory oversight program. We are in the process of revising and updating our recycled water regulatory program. This update will be developing more effective, efficient, and creative ways to provide our services. A significant part of this process is meeting with stakeholders. As the City of Carlsbad is a major stakeholder, this is an advance invitation for you to participate in the stakeholder meetings. The meetings should start in several weeks and the update process concluded by June 30, 2004. The final outcome of the process review may change how DEH presently interfaces with agencies in connecting irrigation users to recycled water systems and overseeing other approved uses. However, DEH will do everything possible to assist you in meeting your Phase n implementation schedule. If you have any questions, please contact me at 858-694-2548.

As you are aware, the Encina Basin Water Reclamation Program, Phase II project is an expansion of our existing recycled water program from a demand of 2000 acre-feet per year (afy) to over 5000 afy. This recycled water demand is based on supplying irrigation water only. The Carlsbad Municipal Water District (CMWD), a subsidiary district ofthe City of Carlsbad, will be completing constmction of the subject project by January 2005. Funding forthis $40 million project was obtained through loans, grants, and rebate programs from Federal, State, and local agencies. Beginning in Fiscal year 2004-05, the program has a condition to sell a specified minimum average annual amount of recycled water over each of the subsequent twenty fiscal years of operation. The recycled water demand is also required to increase periodically on a specific schedule until the demand reaches its planned target. To meet the annual recycled water demand schedule, we prepared an implementation plan that addresses the involvement of the City, the County Department of Environmental Health (DEH). and the State Department of Health Services (DHS). The implementation plan is a compilation of a schedule to connect parcels to the Phase II pipelines, together with processes to be used in making the connections. Enclosed for your review are the components ofthe implementation plan, which is outlined as follows: • A summary of the process to be used, in coordinating activities between the City, the DEH. and the DHS in connecting each parcel to the recycled 1635 Faraday Avenue • Carlsbad. CA 92008-7314 • (760) 602-2720 - FAX (760) 602-8562 water system. A typical method of abandoning a disconnect vault and potable meter is also included. • Phasing Schedule - This Infonnation is provided on a map showing the location of parcels that are planned to be connected to the recycled water system each fiscal year. Each parcel was reviewed and placed in one of three categories (i.e. new development, conversions, and retrofit sites) There are approximately 420 new sites identified at this time to be connected to the Phase II system. • Implementation Status - This includes a map showing the current status of each parcel as it follows the process involved in connecting to the Phase II recycled water system. Parcels connecting to Phase II pipelines are separated into the categories described above. As we discussed at our meeting, we intend to focus first on new development followed by conversions, and ending with parcels needing retrofit. As each parcel is connected to the system the map will be updated to refiect the change. We will also be maintaining a database on each parcel tracking its status. • Disconnect Vault Process - This includes a map showing the location of "disconnect vaults", which currently supply potable water to sites already approved for the use of recycled water along with details on each disconnect vault (i.e. as built drawings and photographs). This information was previously submitted to you at our meeting. We are requesting your review of the implementation plan outlined herein and a commitment from the DEH to assist in meeting the proposed schedule. We plan to meet with Mr. Brian Bernados, District Engineer, with DHS to approve our approach for abandoning the potable water supply at each disconnect vault and other aspects of our plan. If you have any questions, or require further information, please call me at 760.602.2768. Sincerely. WillianriTEr Plummer Deputy City Engineer cc: Glenn Pruim.

Developer submits two (2) sets of landscape irrigation plans to CMWD and DEH. RW numbers are assigned by DEH. and current DEH processing fee is paid estimated at $105/hour c. Developer makes any required revisions to plans based on DEH and CMWD comments. d. After revisions are completed to satisfaction of DEH. then Developer submits mylars for signature to CMWD and then to DEH. e. DEH and CMWD conduct "Recycled Water Cross-Connection Control Shutdown Test and Overspray and Runoff Test. f. CMWD monitors status in recycled water parcel connection database. CONVERSION This process assumes property was developed using approved recycled water plans, but currently uses only potable water for irngation. Reference is made to process outlined in "Recycled Water Plan Check and Inspection Manual February 2001. a. DEH and CMWD conduct "Recycled Water Cross-Connection Control Shutdown Test and Overspray and Runoff Test. b. Disconnect vault is removed or potable water meter is disconnected from irrigation supply. See process described below. G. CMWD monitors status in recycled water parcel connection database. RETROFIT This process assumes property was developed priorto the requirement to use recycled water for irrigation in Carisbad. a. CMWD performs site survey. Reviews site irrigation system and water uses. Verifies irrigation system was installed per plan, or shows basic modifications. b. CMWD prepares "Proposed On-site Reclaimed Water Retrofitting Plan" for each site. (See attached for example). A package shall include site drawing, standard notes, and project description placed in a three ring binder. c. CMWD prepares a group of 10 to 15 sites and submits two sets for plan check to DEH on behalf of property owners along with plan check e. inspection fees. Any DEH comments or revisions are completed on the plans and then DEH signs each single sheet drawing "mylar" CMWD verifies that sprinkler heads are marked, control valves and valve boxes are labeled, existing quick coupling valve removed, and install siqn to indicate on-site recycled water use. CMWD schedules with DEH and property owners several "Recycled Water Cross-connection Control Shutdown Test and Runoff Test for sites to be conducted on the same day and in the same vicinity. (DEH can perform up to 3 to 4 test sites per day). Individual property owners must be converted to usmg recycled water within 12 months of testing. Shut down tests are scheduled with DEH on a first come first serve basis A site includes a parcel and more than one meter can be included per parcel or f. CMWD monitors status of conversion in recycled water parcel connection database. DISCONNECT VAULT REMOVAL PRQCFS.q Some large irrigation sites in the City have approved recycled water irngation systems installed, but are supplied potable water through disconnect vaults on a temporary basis until recycled water can be provided. To remove the potable water supply the following will be perfonned. a. The potable water control gate valve will be closed on each end ofthe vault. b. The spool pipe in the disconnect vault will then be removed c. Blind flanges will be installed on each gate valve in place ofthe spool pipe. d. Perform shut down test on the recycled water system. e.
