INTRODUCTION Costa Real Municipal Water District (CRMWD) is the public water service agency for a 2O,OOO-acre area bounded on the west by the Pacific Ocean, to the north and south by the Buena Vista Lagoon and the Batiquitos Lagoon, and to the east by the communities of San Marcos and Olivenhain. Because of its geographical setting with respect to the six communities that form the Encina Regional Water Pollution Control Facilities, the CRMWD service area has become the focal point of a large, potential marketplace for non- potable water service to augment the public potable water supply that is furnished by the CRMWD. As a matter of fact, extensive pipeline facilities, several wa·stewater reclamation plants, pump- ing stations, and other appurtenances have been constructed in recent times and some of these facilities now have the capability to produce and transport a suitable non-potable water supply for immediate use. CRMWD has been active for many years in continu- ally assessing the total water resources management program for the entire service area. In view of the current status of the many facilities that are now available and that can be integrated into a functional network of non-potable water service facilities, the authorization for the overview of supply sources and the detailed engineering mas- ter plan study is an appropriate step to be taken. The results of such a study wi 11 guide us as we move into an era of rapidly expanding opportunities to make available, to both current and future CRMWD customers, an alternative water supply of adequate quality and sufficient quantity to serve the supplementary needs of our residential, commercial/industrial enterprises, and agri- cultural pursuits • The overview of potential sources of non-potable water supply is important from the standpoint of long-range planning and inter- agencies cooperation needed to develop a successful program. We are fortunate indeed to have this rare opportunity to work in coordination and cooperation with our several public agencies with whom we share common goals to provide a new level of water service consistent with efficiency, economy, and complete public health safety. There is presented .herewith our detailed report and to a very large extent, this study reflects upon the development of overall plans, construction, and implementation of an extensive public potable water system that has served the CRMWD area since 1954. Additionally, we are fortunate to have a. large area of informa- tion and activity of the several wastewater reclamation -sewerage agencies who have been working for many years towards the goal of wastewater reclamation and reuse. We acknowledge the generous assistance and cooperation of all the public agencies who currently operate the various wastewater treatment and reclamation facilities in and around the CRMWD -1- ..

These agencies constitute our initial group of potential producers of non-potable water and ar-e the owners of the extensive pipeline facilities which traverse· the various sectors of our CRMWD. This pipeline network can be readily integrated and used as a part of our CRMWD's functional non- potable water system. These agencies and their representatives with whom we worked closely are as follows: BUENA SANITATION DISTRICT CITY OF CARLSBAD ENCINA JOINT POWERS AGENCY LEUCADIA COUNTY WATER DISTRICT CITY OF OCEANSIDE SAN MARCOS COUNTY WATER DISTRICT Mr. Jim Frandsen, Deputy Di rector of Public· Works, County of San Diego Mr. Les Evans, City Engineer (to May, 1982) Mr. Dennis Reid, General Manager · Mr. Richard Hanson, Manager (to March, 1982) Mr. Jim Turner, Water and Sewer Superintendent Mr. Jim McKay, General Manager This study project has received a substantial amount of background information from the Buena Sanitation District, the Vista Irri- gation District, the Oaon Corporation, and the developers of the Shadowridge Community, which incorporates a total wastewater rec- lamation and reuse facility.

SCOPE AND PROCESS OF STUDY Thi s study program i s di rec t e d pr i ma r i l y to the re ta i l s er vi c e area of the CRMWD, with the concepts set forth herein for the City of Carlsbad water service area being intended as recommendations for consideration by that retail water service agency. The City of Carlsbad functions as a sub-agency of CRMWD in terms of CRMWD's role as the supplier of potable water to Carlsbad, and CRMWD's position as the member agency of the San Diego County Water Authority. Membership in the San Diego County Wat·er Authority is a requirement for applying for possible financial aid by the Metropolitan Water District's Local Projects Program in the development of non-potable water resources. Exhibit ''A" of this report, entitled "Master Plan for Public Non- Potable Water System", delineates in detail the entire study area • The goal of this master plan study is to adequately identify the utilization of all of the existing non-potable water service fa- cilities that have already been constructed within the boundaries of the CRMWD service area and to identify those new facilities that are appropriate to commence the initial levels of non-potable water service within the CRMWD. The fundamental and basic theme of this master plan is the simple fact that non-potable water service should be made available on an equivalent basis with non-potable water from the following standpoints: * -* * Availability Quantity Service Characteri sties In effect there should be virtually no difference to the CRMWD customer in using the non-potable as opposed to the potable supply. Inasmuch as the development of a public water system entai 1 s basic design, the entire study area is analyzed from the standpoint of topography, starting with the area along the Pacific Ocean and moving back inland to lower foothill elevations of 500-600 feet. Additionally, the proposed service area has two principal water- sheds, namely the Agua Hedionda Creek (Agua Hedionda Lagoon) and the San Marcos Creek (Batiquitos Lagoon) areas. The Buena Vista Creek area to the north and the smal 1, centrally located Canyon de las Encinas drainage basin comprise the remainder of the service area. As an emerging program, a careful assessment of the potential of the marketplace for non-potable water service is necessary. Be- cause there is a direct rel at i onshi p between non-potable water usage and land-use planning/development concepts, projections of a practical system must take into account the substantial expenses for a dual water system and the various contractual considerations such as quality, quantity, and pricing • -4- ,. ' .. ... .. ,. l.. ... I. ... .. I"' .. .. i.. ... ... ... ' .. C .. .. ,. .. The basic engineering design of a non-potable water system should be tied into the existing arterial network which is a result of the new reclamation facilities that have Tecently been constructed, and those that are proposed in the near term. Addi- tionally, attention must be directed to all of the special design features necessary for successful operation of a non-potable water system intended for i rri gat ion as well as the management of the non-potable water system with regard to the public health and safety. In other words, the introduction of a water supply of this character represents a formidable regulating task regarding cross-connection control, and potential ·unauthorized uses. In the actual development of the entire arterial master plan, it is proposed to fully utilize all the existing facili- ties, together with proposed pipeline facilities that would be constructed in order to insure service reliability that would be effected by inter-ties between all systems. The study program would also identify the process by which a fully integrated non-potable water system utilizing a number of separate sources would be operated on an optimum basis to gain the greatest amount of efficient water usage • We have al ready commented upon the fact that this study repre- sents an "implementation phase" of the several facilities con- structed by neighboring wastewater reclamation agencies. Accord- ingly, our study program has drawn heavily from the engineering, environmental and master planning reports that have been previ- ously commissioned. These reports are listed in the Bibliography of this report. In particular, we stress the fact that this master plan represents a functional updating and refinement of the City of Carlsbad -Wastewater Reclamation Master Plan Study which focuses upon a major portion of the service area of CRMWD • -5- .. ..

HISTORY AND BACKGROUND WATER RESOURCES PLANNING FOR NON- POTABLE WATER The or191 n of the CRMWD in 1954 goes back to a time when the local community water supply was becoming scarce in terms of quantity, and the deteriorating quality was fast precipitating the destruction of the local agricultural pursuits. The intro- duction of imported water, first from the Colorado River and in more recent times northern California water, spurred us to the high 1 evel of community development which we now err joy, as well as aiding the vast agricultural enterprises within our service area. CRMWD, along with all of Southern California, depends heavily upon the imported supp"ly and recognizes the importance of moving towards a mode of water conservation. The inventory and potential reassessment of the local supplies is necessary so that in the future, we may continue to enjoy the good fortune of an ample water supply, at an affordable cost • An earlier milestone of this philosophy was during the early 1970's when a large petroleum refinery was proposed in the CRMWD service area. There was a projection of some 3.0 million gallons per day of water (mgd) required for the refinery. After a review of extensive engineering reports, the CRMWD Board of Di rectors decided that a total of 1.5 mgd of fresh water would be provided to the refinery and that the remainder would have to come from the reclamation and recycling of wastewater originating in the San Marcos County Water District. Although that project never moved forward beyond-the planning stages, the reel aimed water policy position of the CRMWD became firmly established. Simply stated, within certain limits and certain areas, the integrated concept of water resources utilization would include local, imported, and wastewater supplies. During the middle 1970's, Southern California experienced the hardships and difficulties of the long-term and state-wide drought. During that time, the CRMWD launched an aggressive water conservation program, and enunciated a basic policy posi- tion that there would be, in time, a viable water reclamation program utilizing our long neglected local supplies. This policy would offer CRMWD customers a secondary or "non-potable" water supply • At this point, it is appropriate to set forth some specific definitions for the purpose of this study report: 1, Non-potable water service is intended to describe a class of water supply that 1s suitable for purposes other than human consumption pursuant to regulatory constraints. It is important to point out that non-potable water service can include such sources as local groundwater supplies, local stream supplies, as well as reclaimed wastewater • -6- .. .. ... C .. ... r-... C .. ! ... .. .. ,.. I. ,.. ' ... C .. .. "' I.. "' .. ,.. ' ... 2. The term reel aimed water or reel aimed wastewater is uni- versally used to describe the end product of sewage (wastewater) that has been adequately treated to meet the level of quality appropriate t9 given use. 3. Sub-potable water --This is a recent term promulgated by the Metropolitan Water District of Southern California to identify a class of water below that of potable water. For the purposes of the CRMWD, the terms non-potable water and sub-potable water are synonomous • In 1977, the Encina sewerage agency developed a significant problem in terms of sewage tre.atment capacity which negatively affected several of its member agencies. As a result of that situation, several member agencies of Encina proceeded with individual plans for the construction of wastewater reclamation plants in order to provide fo·r sewer service capacity. As a result of this surge of new interest and activity in wastewater reclamation, the CRMWD became the focal point of the several marketing analyses inasmuch as the bulk of the agricultural activities and potential urban developments are located within the boundaries of the District. Inasmuch as the CRMWD's important responsibility of community water resources management would be substantially impacted by these new developments, the District expanded its spheres of activities in working with the San Diego Regional Water Reclamation Agency and the San Diego Water Reuse Study. Ultimately, the Water District became a charter member of the Association of Water Reclamation Agencies of North County, a coordi nat i·ng group 1 ocated in the North San Di e·go County area. This master plan study represents the first formal coordination and implementation effort directed at the results of the several sewerage agencies who have actively pursued their own projects, and are now in an operational mode capable of producing non-potable water. It is very important to maintain the continuing commitment of all of the agencies involved in this new era of providing for a dual water supply to our various communities so they wi 11 actively pursue an aggressive non-potable water supply program • -7- -..

C C C C C C C .. C C C IV • PROJECTED NON-POTABLE WATER SUPPLY NEEDS AND FUTURE MARKETING PROGRAM As mentioned earlier, the CRMWD service area was targeted as a prime marketing area for non-potable water as generated by the several wastewater reclamation plants. The various engineering studies sponsored by the City of Carlsbad, as they launched their wastewater reclamation program, went into great detail with res- pect to t h.e market i n g of non -pot ab l e water. We di rec t you r attention to the reports listed in the Bibliography which contain a wealth of information regarding the future utilization of non-potable water. A detailed review of these reports indicates that at this time, there are aaditional studies being conducted concerning the chemical quality of water that can be used in various sectors of the CRMWD service area. In particular, the Agua Hedi onda Creek wat·ershed; upstream of El Cami no Real, is being analyzed. As a consequence, at this time there are still limitations upon certain locations where the various supplies can actually be utilized. This being the case, the CRMWD has focused its attention to the areas where at some future time, dependent upon quantity, quality (chemical), and costs, non-potable water can be utilized. In this arena, we have identified three separate specific potential marketplaces, listed as follows: 1. Public facilities utilizing water service for open space, greenbelts, landscaping, ornamental lakes, and other such pastoral and recreational uses. In this broad category, the largest potential users of non-potable water would be the proposed Macario Canyon Park of the City of Carlsbad, the proposed regional parks of the County of San Di ego -Lake Calavera and Batiquitos Lagoon, and the numerous public open-space equestrian trails and greenbelt areas that wander through the various areas of the City of Carlsbad and are common to the CRMWD service area. Additionally, non-potable water service would be made available to the State of Cali- fornia -South Carlsbad Beach, the State of California - Cal Trans for the extensive freeway landscaping along Interstate 5, the proposed landscaping on Highway 78, the Palomar Airport area, the smaller public parks and public school campus~s sites that dot the service area. 2. Private devel.opment uses -1 andscapi ng, greenbelts, golf courses, ornamental lakes, and other such secondary water supply uses. In this particular non-potable water service usage category, the City of Carlsbad, the principal land- use, planning and control agency. within the CRMWD, has extensive policy programs with respect to landscaping and beautification of the countryside. As a matter of fact, in some instances, there are rather intensive landscaping programs from the standpoint of water usage so that this would tie a strong potential marketplace for non-potable water. -9- ~ ~ ~ ' • ~ • ~ ~ ~ ~ ~ ~ ~ ~ C ~ ~ I ~ ~ ~ ~ ~ ' ~ ~ ~ ~ ~ ~ ~ ~ • • ~ ~ ~ ~ ~ ! -EXPERIMENTAL LANDSCAPING -COSTA REAL MUNICIPAL WATER DISTRICT ,.. ..

In this last category, Ute example given earlier in this report relating to a propo~ed petroleum refinery is an example of a specific, special non-potable water service customer. Because of the potential of some rather substantial volumes of non-potable water se·rvice that can b.e made available, it is entirely possible that we could have, in the future, a major industrial-commercial activity that could have a demand for process or cooling water of a quality that can be met by a properly treated non-potable water.. This woul ct be an ideal example of a potentially cost-effective water reclamation and reuse within the sphere of non 7 potable water service. In 1979, CRMWD worked in conjunction with the San Diego Water Reuse Study in conducting a marketing survey among the then agricultural customers of the district. A total of 20 inquiries were sent out to the customers and si )(. responses were received from the active customers of that time. In terms of total po- tential water volume, there was a positive response from the La Costa Golf Course for utilization of some 500,000 gallons per day for golf course irrigation subject to the quantity and qual- ity constraints that woul ct be expected. The next response in the order of magnitude was a large floral enterprise, and here again, the projections for non-potable service were based upon a large-scale agricultural pursuit which did not have a firm pros- pect of continuing for a long term. Insofar as public facilities such as the schools system, the freeway, and the local parks, very little potential in terms of significant volume of non- potable water was expressed via the questionnaire. The Lake Cal avera Hi 11 s -Master Planned Community development submitted a comprehensive set of information as to their pro- jection of "potential irrigation areas using reclaimed water". Briefly, the submittal indicated that some 500 acre-feet per year would be utilized within their 800-plus acre development on a 5-year development time mode. In addition, the flow rate of some 450,000 gallons per day was estimated. As matters now stand, the first unit of the Master Planned Community, comprising 138 single-family dwelling units, currently utilizes potable water service for landscaping. The second phase, a development of 230 dwelling units {duplexes and four-plexes), will likewise be served with potable water service for all landscaping. At the present time, the City of Carlsbad is moving forward with a comprehensive policy-program in their land-use regulatory role to require dual water systems and use of non-potable water when such becomes available. To date, no specific development projects have moved forward with actual construction of dual water systems within the service area of the CRMWD • In view of this significant policy direction of the land-use regu- lating agency of our service area, namely the City of Carlsbad, it became very important that the water resol!rces management -12- C ,. i.

Accordingly, there is a need for a well-planned and organized marketing program which will have a firm financial foundation upon which a customer can project the benefits that accrue, while taking into account the substantial financial burden for the construction of a complete secondary or dual water system within the customer's area of activity. From the standpoint of the producers and CRMWD, the distribution and marketing agency, firm contractual arrangements wi 11 be necessary to insure the stability of the "commodity" as the emerging program develops. It is very important to recognize that the concept of a "cooper- ative" among all of the producers as well as the di stri bu tors wi 11 be the key element in organizing a cost-effective non-potable water service program in the entire region, as well as the CRMWD service area. One contractual arrangement has been achieved to date involving the CRMWD, Buena Sanitation District and the Daon Corporation. The latter two entities own and operate the Shadowridge Wastewater Reclamation Plant in Vista. The existing contract calls for the plant to supply a quantity of non-potable water for distribution by CRMWD at the Koll Company construction site adjacent to Palomar Airport. The three-party agreement can form the basis for future contractual arrangeme.nts between the District and other non- potable water producers. The entire contractual documents for this new venture are included in the Appendix of this report. For the purposes of this Master Pl an Study, the assignment of defined volumes of non-potable water service to specific areas of the CRMWD has not been attempted. Such an assignment would not be productive given the attempt of this initial evaluation of potential customers. Given the locations and sizing of the facilities constructed to date, there is substantial flexibility at this time to move the modest volumes of water that can be expected to be utilized in the next three to five years. At this point, it should be pointed out that master pl an studies, such as this, are viable documents that should be continually updated and assessed. However, in no event should they be permitted to lay delrmant in excess of five years from their inception. We do invite the careful review of the numerous reference docu- ments which contain detailed data as to future projections. The consensus of these reports indicates a range of 3.0 to 5.0 mgd (3,000 to 5,000 acre-feet per year) of non-potable water supply will be available to fulfill the initial marketplace needs. The only limitation now existing upon the facilities identified in this Master Plan Study is the practical limits of pipeline capaci- ties, based upon the economics of pressure gradients and the need for supplementary pumping of the water supply. With a 12-inch diameter minimum pipeline size, quantities on the order of 3 to 4 -15- r·1 r·1 r1 r·1 r1 r1 r, r·1 r1 r·1 ..-·1 rt r1 r1 r1 r 1 ,--1 ,--, r·1 I ......

Ultimately, the entire network of pipelines, both arterial and local service lines, wi 11 develop ba~ed upon the precise engineering design of specific neighborhood non-potable water systems. Because of the variety of landscaping themes and relative levels of intensity of "greenbelt areas", there will be a wide range-of water demands within the service area • As a matter of current interest, the CRMWD's total sales of agri- cultural water for the last three fiscal years is as follows: F I_SCAL YEAR 1979~80 1980-81 1981-82 AGRICULTURAL WATER USAGE TOTAL DISTRI~T SALES VO~UME IN ACRE-FEET -17- 4,255.50 4,180.00 4,145.00 ,.. ... ,..

There is presented herewith "Table A" which .sets forth the specific details for a total of six wastewater treatment plants that are currently producing treated reclaimed water or are capable of doing so: -18- ... ..

A careful analysis of the information contained in "Table A" W i l l q U i Ck l y i SO l ate the fa Ct that the CR MW D s.e r Vi Ce are a ha S virtually an unlimited source of non-potable water from reclaimed wastewater in terms of volume. Several detailed studies that have al ready been conducted would indicate that the successful reclamation program must have ample reserve production capacity. At this point, it. is very important to point out that this Master Plan Study is limited only to the distribution and marketing of nonpotable water. Accordingly, we make no attempt to isolate and identify the areas of various additional treatment plant im- provements necessary in order to attain the quality requirements as set forth by the appropriate regulatory agencies. Stated another way, CRMWD would look to the producers of non-potable water service to have the firm ~nd direct responsibility for the production of a water supply that wi 11 meet all of the re qui re- ments in terms of regulatory agencies, and the customer who will be served. Because of our working experience and k~owledge of the CRMWD ser- vice area, we do offer suggestions as to the potential future of other sources of non-potable water. With respect to reclaimed wastewater, we believe the proposed Palomar Airport treatment plant site (northeast corner of Palomar Airport Road and El Camino Real) is a viable site. The site is a point of concentration of the large volumes of raw sewage which would be pumped from the communities of Vista, Buena, and San Marcos. There would be a substantial economic advantage to have a large reclamation plant in the Palomar-El Camino Real area (elevation 275-300) so as to take advantage of the head available for distribution of the non-potable water. From the standpoint of economics, one must always remember that it is more costly to pump raw sewage than it _is to pump treated wastewater. We also see the potential of a local wastewater reclamation plant in the area of the proposed community high school campus on Cannon Road to the north of El Camino Real. In fact, this proposed site could have a direct tie-in with the existing Lake Calavera facility as will be further discussed in this report. As we have mentioned several times previously, while there is a current emphasis upon treated wastewater being the non-potable water supply, we should not overlook the potential of our local water supplies. In the case of the CRMWD, the several stream flows and the existing well field of Agua Hedionda Creek north- easterly of El Cami no Real in the area of the Rancho Carlsbad mobilehome park have possibilities. In the case of the stream flows, the CRMWD, on a timely basis, should evaluate the potential of diverting waters to the several storage reservoirs that could be developed. These waters could even be pumped directly into the system in the spring and early summer months for however long there is sufficient run-off. In the case of the Agua Hedi onda well field, an inventory would be necessary of the potential yield from the basin tied together -21- ,. -.. I Ill .. .. .. Ill .. .. .. 11111 ..

Of•even greater importance and significance would be the vast potential of restoring the San Luis Rey River groundwater basin to produce a local water supply of satisfactory quality, again within the framework of a vigorous economic analysis. Additionally, this is very important from the standpoint of being the one significant source of a local water supply in the event of a major water shortage or crisis in the Carlsbad community, the service area of the CRMWD, and City of Oceanside (who in the past ·has utilized the San Luis Rey River water supply). -23- .. .. .. 1111 .. ..

EXISTING FACILITIES AND PROJECTED INTEGRATION OF FACILITIES IN DISTRICT SERVICE AREA Exhibit "A" delineates in detail all of the public wastewater reclamation facilities of the City of Carlsbad, Buena Sanitation District, San Marcos County Water District, and the Leucadia County Water District, In addition to the actual treatment plant facilities, Leucadia County Water District, Buena Sanitation District, and the San Marcos County Water District have existing "fail safe" effluent lines that transport treated wastewater to the ocean outfall system of the Encina regional facilities. CRMWD has taken advantage of the strategic locations of these new pipeline facilities. In recognition of our emerging role as distributors of the non-potable water service, arrangements were made during construction to actually build a total of six outlets along both the San Marcos and Buena effluent pipelines. In every instance, they are positioned to take advantage of extending pipeline facilities to current or projected market- pl aces, utilizing the existing rights-of-way of CRMWD. In addition to the construction of the several outlets, CRMWD was fortunate to enter into a cooperative agreement with the City of Oceanside for the construction of a 12-inch non-potable water service line in the Highway 78 -El Cami no Real freeway inter- change bridge. This line permits an inter-tie between the City of Oceanside's advanced wastewater reclamation system and the potential customers of the CRMWD and the City of Carlsbad, We would add that at the request of Cal Trans, there has al ready been constructed in ·this new pipeline two outlets for future freeway landscaping. The proposed master plan which has emerged from this study report identifies the total integration of all of the existing facilities built by local public agencies so that there is maximum use of the pipeline facilities constructed to date • The Encina Water Pollution Control Facility (EWPCF) stands out in its magnificence as a result of its recent upgrading and expansion, so as to permit an ultimate expansion to 45 mgd • Al though there is a full secondary treatment level for the current 22.5 mgd plant, efforts are now underway to permit the overall treatment p'l ant operation to conform to an advanced primary level of sewage treatment. Accordingly, any significant level of wastewater reclamation at the EWPCF will require a major construction effort. Because of its elevation, i.e • approaching sea level, the reclamation of wastewater at the EWPCF would be expected to take pl ace at some point well into the future, at such time when the required. volumes for non-potable water service overtax all of the upstream facilities located at higher elevations. -25- ... .. -... -... ..

DESIGN CONSIDERATIONS FOR NON-POTABLE WATER SYSTEM As a basic policy statement, CRMWD intends to operate its non- potable water system as a supplement to the potable water system so that in all particulars, there would be identical design parameters and considerations for the non-potable water service that are currently active for the potable water system. Recog- nizing that the prime goal is to offer to the water customer the secondary water supply at the potable water convenience 1 evel, it is very important that there not be introduced so-called "second level" service requirements. Because the heavy emphasis will"be upon landscape irrigation, the non-potable water system wi 11 require a rather high 1 evel of water service pressure. Accordingly, the entire service area will be laid out to all~w a minimum water pressure of 40-50 pounds per square inch (PSI) up to a maximum of 140-150 PSI. From our exper- iences in operating the potable water iervice, we have a rather hilly terrain so that it would be very expensive to try to main- tain a uniform water pressure throughout the area. In the case of the proposed master plan system, there will be more localized areas of individual pumping stations because the existing network of fai 1 safe 1 i nes has, in several instances, 1 ow-pressure fl ow characteristics. Of course, in time, as there is paralleling of these facilities, there can be more precise engineering designi to take advantage of pressure conditions wherever possible, All pipeline sizing at this time is for a minimum of 12-14 inches in diameter. This size range has been established in view of the fact that the potential marketplace as currently assessed will account for a rather modest volume of flow. Design velocities of 8-10 feet per second utilizing asbestos cement or poly-vinyl chloride pipe material will allow for flows in the magnitude of 4,0 mgd • The non-potable water system wi 11 have a marked departure from the potable water system from the standpoint of storage require- ments needed to compensate for the peak flow conditions that will occur on a daily basis. The non-potable storage system will need to accommodate for the variation in production rate at the reclamation plant and more importantly,.the seasonal produc- tion and usage vari.ation will have to be accommodated, In the case of local service areas, detailed design of the irrigation system will yield the regulatory storage needs, For seasonal storage, the San Marcos County Water District's new facilities are an important "first on line" reservoir. Within our District service area, the existing Lake Calavera plant owned by the City of Carlsbad -Water Department has great potential as a seasonal storage facility. More detailed studies will be appropriate at a future time when the regulatory constraints are resolved for all parties concerned, · -26- ,.. I - i ... ... I .. ... - ,. • .. ,.. ,. ,. I -,.. i,,. C ,. ... C One important sidelight to the operation of the non-potable water system involves having faci 1 it i es where the non-potable water supply can be augmented by the freshwater supply 1 n the event there is a reduction or termination of production at the waste- water reclamation plants. At CRMWD, we would propose that the non-potable water service reservoirs be located adjacent to our potable water reservoirs and in the event there is a need to supplement the supply, there would be a simple "overflow" arrange- ment. Such an overflow system from the potable supply to the non-potable supply would be accomplished with a Health Department approved air-gap separation type of service. Additionally, there may be a pl an developed to construct the non-potable supply reservoirs consisting of ground-level containers manufactured of a synthetic fabric. This approach would minimize both operating expenses and capital costs. From the standpoint of pi pel i n-e design, there must be positive identification of the potable and non-P.otable systems to assure the maximum protection of the public health. The construction of a public non-potable water system is practically identical to that of the potable water system, with the fundamental exception being the need to incorporate a sufficient and distinctive marking so as to permit the underground and ground surface faci 1 i ti es and appurtenances to be properly identified. There is now a wealth of detailed rules/regulations and construction specifica~ tions with respect to the construction of non-potable water systems. The CRMWD is in the position to review such information so that the preparation and adoption of specific rules and regu- lations and design and construction standards for such systems can readily be accomplished. This element of the overall non- potable water service program wi 11 be handled as a separate matter. As mentioned earlier, one of the basic policy positions of the CRMWD wi 11 be to establish non-potable water service at a com- parable level with potable water service. This will assure that all pipeline facilities, valving systems, pumping systems, and storage facilities will be de5igned and constructed on the basis of good, functional design procedures, utilizing proven materials and equipment. Combined with good construction techniques, a first class, functi'onal distribution system will result. We would anticipate that the CRMWD's standards shall adhere to the current practices that are now proving successful here in Southern California • -27- ,.. I"' 1,, VIII. PROPOSED ARTERIAL NON-POTABLE WATER SYSTEM ... L. ,.. .. ,.. .. ,.. ' .. r .. C .. 1111 .. .. r .. ... ' ,.. .. .. .. .. .. ... .. ... ,. ' .. On the basis of the evaluation of all of the existing non-potable water system facilities in the CRMWD service area, as well as the strategic locations of the several existing and potential sites for the production of non-potable water, our task has turned to identifying the first elements of a totally integrated arterial distribution system to supply our emerging marketplaces. Exhibit "A", our "Master Plan for Public Non-Potable Water System", has been formulated with the intent of linking together all of the currently existing supply sources as well as the Lake Calavera Hi 11 s reel a mat ion pl ant. The Shadowri dge pl ant and the Meadowlark plant have existing ''failsafe facilities" which join together to the west of El Camino Real and south of Palomar Airport Road and then travel westerly to the EWPCF plant site. Our first goal is to be able to take advantage of the utilization of existing out- lets which have already been constructed.in these two lines. Each of the outlets, 12 inches in size, have been located to accommodate a potential local service area and also to take advantage of additional distribution facilities from these take-off points paralleling the CRMWD's existing potable water lines. We note that the master plan identifies in some detail the existing potable water system facilities, and we have done this to highlight the fact that both the agricultural irrigation customers as well as our urban customers are currently utilizing the potable water facilities as delineated on the exhibit map. St art i n g w i th the s o·u the r l y sector where the ex i st i n g Leu cad i a reclamation plant stands ready to be activated, we are proposing a major line to be extended to the north side of the Batiquitos Lagoon, then westerly, and ultimately terminating at the junction point of Lagoon Lane and Poinsettia Avenue just east of Interstate 5. This routing would provide ample opportunity for sufficient volumes of non-potable water to care for all of the potential needs of a future regional park or greenbelt and landscaping for urban developments all along the north shore of the Batiquitos Lagoon. There is an additional east-west tie from the old Coast Highway at its intersection with the proposed Poinsettia Avenue moving easterly and northerly along a ridge line, where we have extensive irrigated 'agriculture, easterly to El Camino Real, then northerly a short di stance to intersect with the existing San Marcos failsafe line. You can see immediately from this layout that the entire southern area of the Water District westerly of El Camino Real can have ready access to non-potable water service from either the Leucadia system or the San Marcos system and, de- pending upon the availability and quantities, there would ulti- mately be total integration of the full production capabilities of those two agencies • In the central area of Palomar Airport Road, westerly of El Camino Real, we have an important linkage between the San Marcos line and the Buena line along El Camino Real. Here again, this gives us -28- ... 1111 C I"' I ... ... .. ... 1111 ... 1111 !"' -... .. ... .. !"' I .. I"' I ... ... ... ... ... "" ... ... ' .. ... I. the flexibility of an interchange of flows between the San Marcos facility and the Buena facility. Additionally, in the event the proposed Palomar Airport reclamation facility is determined to be the most practical location, these pipelines would serve as trans- portation facilities from that location. Moving northerly .and westerly from the intersection of Palomar Airport Road and El Cami no Real, the District would propose an arterial line along the north side of Palomar Airport and into the area of the Carlsbad Research Center industrial development • We fully expect that this new 55O-acre industria•l-commercial center will become an active marketplace for non-potable water service, particularly as evidenced by the plans for a landscaping program, together with a large ground cover area for manufactured slopes. The routing of a non-potable water service line in College Boulevard, which would have linkage from Palomar Airport Road northerly all the way to Highway 78, has led us to the idea that the line should proceed northerly,_crossing El Camino Real, moving to the area of a proposed reclamation plant at a new high school site, and continuing northerly to Lake Calavera. At this point, we should explain that in the day to day operation of a vast arterial water system network, you must have distribu- tion storage and additionally, seasonal storage. There have been previous projections as to potential sites for seasonal storage reservoirs; however, we believe that the Lake Calavera facility merits a very careful analysis inasmuch as the existing lake is currently serving no functional purpose insofar as its owner, the City of Carlsbad -Water Department, is concerned, There is also the potential that the activation of the Buena Vista Creek reclamation facility of the City of Oceanside may result in the construction of an arterial pipeline easterly along Highway 78 which could ultimately provide a routing to store water in Lake Calavera. Along this sector of the College Boulevard pipeline, there is also the potential of constructing a pipeline facility that would tap the stream flow of-the Agua Hedionda Creek, a little under one mile east of the future College Boulevard location. The City of Carlsbad' has constructed the Lake Calavera Hills rec- lamation plant; however, it cannot become operational until such time a ''failsafe line" has been constructed to tie into the EWPCF ocean outfall. We have identified a possible routing of the fail- safe line that could be constructed from El Camino Real southerly in the right-of-way of an existing flood control channel, be extended across the ''slough" area of the Agua Hedionda Lagoon and tie in with an existing roadway/CRMWD pipeline system intersecting with the fail safe line now located in Palomar Airport Road. This proposed routing would have the potential of serving the Kelly School, the adjoining City of Carlsbad park site area, and the possible future "wetlands" area. Of course, a portion of this proposed routing would also traverse the City of Carlsbad's new -29- ,.. ... ... I .. ,.. l.. ,.. ' ... "' ... ,. ' .. r ... .. ... ,.. ... ,.. ... .. .. ... .. ... ... i,., ''Macario Canyon Regional Park Site" so that there could be functional uses within that park setting, We have mentioned the potential intertie of the City of Oceanside's Buena Vista Creek reclamation facility into the overall network. The master plan does not specifically identify a pipeline tie-in, We believe that it is more appropriate to have the City of Ocean- side and the City of Carlsbad -Water Department review that area of interest more critically and then come forward with a plan that would serve the functional needs of those agencies as well as potentially being assimilated with the CRMWD's master plan. The identification of the proposed network of arterial pipelines has as its basic goal the stimulation of interest and under- standing of a concept that the non-potable water supply program for the entire region has as its basic foundation of success a "cooperative" approach. This· cooperative approach would be with regard to sources of supply, facilities and a full integra- tion of the subsequent new construction that will bring all of the interacting features together. In some respects, we are uniquely blessed by the fact that several programs are al ready in motion and that the entire region can benefit from the efficiency and the economics of a fully integrated system, While there is a host of details to be identified and attended to, the overall strategy from the standpoint of the network of distribution systems .is to bring into motion the full range of transferring waters from the areas of production and availability to the areas of specific need based upon a practical scope of marketing • The character of this master plan network is such that no attempt is made at this point to identify in detail pipeline sizes (other than the minimum size of 12 inches}, their lengths, pressure ranges, locations and sizes of pumping stations, locations and sizes of storage reservoirs, and all of the other details that are involved in the design of an operating water system. From the standpoint of economics and practicability, experience has shown that there needs to be a specific non-potable water service program identified, following which there should be a vigorous and detailed engineering analysis of the physical facilities that are required ahd ultimately an economic analysis that can demonstrate the viability of the non-potable water service program to integrate with the existing or planned potable water system facilities • -30- ,. ,. ... ,. ... ,.

IX • SUMMARY AND CONCLUSIONS This report has identified in some detail the multitude of sources of supply for public non-potable water service that could be made available to existing and future water customers of the CRMWD. At a time when the character of the CRMWD is changing from "dry- lands" and agricultural areas to intensive urban developments, we are witnessing a trend for vast expanses of open space, land- scaping, ornamental horticulture, and other uses of our local water supply which may be very adaptable for the u~ilization of a non-potable supply. CRMWD has had the good fortune of being geographically located so that we can readily be served from facilities that our neighboring·agencies have already constructed so that we have a situation that is of tremendous advantage to our service area. On the basis of many years of water resources development, con- struction and operation of vast public potable water systems, we have the advantage to view the potential marketplace for non- potable water service. It is our firm opinion that for a number of reasons, not the least of which is availability and cost of service, non-potable water service will emerge as a cost-effective and community-sustaining program. There has been specifically identified in our master plan an arte~ rial system to fully integrate all of the existing and potential sources of our supply. While the dominant role will be played by wastewater reclamation facilities, we also have directed attention to the potential of local stream flows as well as existing ground- water supplies • This overview and master plan report is now ready for review and input from all of the sectors of the public and business enter- prises as well as all interested, neighboring and participating public agencies who are involved in wastewater reclamation and reuse. Upon the conclusion of public discussion and the formal proceedings by the Board of. Directors of the CRMWD, we would specifically recommend the formal adoption of the plan. Then the Board should establish a formal implementation program, which to a large measure would involve specific contractual negotiations and agreements with the several "producers" of non-potable water. As with the case of any major project of this scope, the ultimate success of this non-potable water service program wi 11 be based upon the ability to design a financing program that wi 11 result in a cost-effective water service which will have to carry the burden of the construction and operation of a complete "dual water system" within the CRMWD service area. -31- I"" .. ,..

Delaney, Executive Officer ~alifornia Regional Water Quality Control Board 6154 Mission Gorge Road, Suite 205 San Diego, California 92120 Dear Mr. Delaney: The purpose of this letter is to request your approval of our District's pro- posal to distribute secondary effluent within the Agua Hedionda Basin near Palomar Airport.: This water, amounting to approximately 100,000 gallons per day for about three months (representing an initial increment) would be supplied by Buena Sanitation District's Shadow Ridge Treatment Plant. Costa Real Municipal Water District would supply it for construction compaction purposes for the Carlsbad Research Center development. This development has moved very rapidly and grading will begin by October 1. I understand the basin discharge standards have been amended to a limit of 3500 mg/1 TDS. Effluent from.the Shadow Ridge plant would contain 1,000 mg/1 or less. Legal arrangements for the acquisition and distribution of this effluent are being worked out now. They will be patterned after the agreement between Buena Sanitation District and Vista Irrigation District. We would be happy to conform to any restrictions you would impose, as we are taking a con- servative approach to the entire water reuse program within our District. We believe this approach will produce a viable reclamation program in the near future. The initial application of effluent for construction purposes would be a sig- nificant step in North County, where, as you know, several agencies have formed an organization to promote reclamation. Publicity of Costa Real 's project would be of mutual benefit to our District and the Regional Board. In this regard, you are invited to attend one of our Board meetings if you are able to approve our request to discharge limited amounts of effluent for the purpose described above.
