<br />USBRIMWD SALINITY MANAGEMENT STUDY <br />FINAL REPORT <br /> <br />. <br /> <br />METROPOLITAN AND OTHER AGENCY COLLABORATION <br /> <br />W <br />OJ <br />l\: <br />l\:' <br /> <br />EXPAND DESERT-COACHELLA EXCHANGE <br /> <br />The existing exchange with the Desert Water Agency (DWA) and Coachella Valley Water <br />District (CVWD) improves Metropolitan's blended water salinity, at current demand levels, by~ <br />replacing CRA water with 61,200 acre-feet of East Branch SWP water in most years. If <br />DW A and CVWD obtain additional SWP supplies, the exchange could be expanded. Each <br />100,000 acre-feet per year of exchange would reduce salinity levels of Metropolitans blended <br />water by about 30 mgIL over a 12-month period. From 1995 through 1998, Metropolitan will 0 <br />have exchanged about 428,000 acre-feet and experienced significant fmancial benefit to offset <br />the costs of its blending operations (see Table 3-4). <br /> <br /> <br /> <br /> <br />T bl ~ <br /> <br />C hll <br /> <br />. <br /> <br />a e Desert oac e a Exchanl!e <br /> Year Desert - Coacbella Exchange (AF) <br /> 1995 61,000 <br />~-----~~--- ~--- ,-_. <br /> 1996 138,000 <br />------------ _00_ 0 <br /> 1997 114,000 <br />-- 0_0000_00__ ____.0 00____ <br /> 1998 115,000 <br /> <br /> <br />LOCAL RESOURCES PROGRAM SUPPORT OF DESALTING AND BRINE LINES <br /> <br />Through its Local Resource Programs (LRP) Metropolitan is contractually committed to <br />10 projects which are expected to remove 58,000 tons per year of salts from Southern <br />California groundwater and recycled water. Metropolitans participation also helps support <br />the cost of brine lines needed for disposal of salts from these projects to the ocean. <br /> <br /> <br />In June 1998, Metropolitan adopted a new LRP with a competitive request for proposals to <br />identifY groundwater recovery and water recycling projects it may participate in. Under <br />existing Integrated Resources Plan goals, additional local production of about 125,000 acre- <br />feet per year will need to be in place by 2020. It is anticipated that a number of these new <br />projects will include groundwater and recycled water desalination and attendant brine disposal <br />facilities. Figure 3-11 identifies existing LRP agreement project locations. <br /> <br />. <br /> <br />BOOKMAN-EDMONSTON <br />ENGINEERING, INC. 3-17 <br />O:\LOCAlRESIANDYSISAUN/TY\IUNE9B-217SECT3oDOC 07120/9810:59 AM <br /> <br />Section 3 <br />Evaluation of Potential Regional <br />Salinity Management Strategies <br /> <br />. <br /> <br />. <br /> <br />.J. _.~ :_.Ji.:"",\~ <br />
