CITY OF SANTA ANA <br />CITY WATER DEMANDS OVERVIEW <br />CIVIC CENTER FACILITIES STRATEGIC PLAN <br />WATER SUPPLY ASSESSMENT <br />Southern California's urban water demands has been largely shaped by the efforts to comply with SBx7 -7. <br />This law requires all California retail urban water suppliers serving more than 3,000 acre -feet per year <br />(AFY) or 3,000 service connections to achieve a 20 percent water demand reduction (from a historical <br />baseline) by 2020. The City has been actively engaged in efforts to reduce water use in its service area to <br />meet the 2015 interim 10 percent reduction and the 2020 final water use target. <br />Section 2 of the City's 2015 UWMP summarizes the analysis of the City's current water demands, factors <br />that influence those demands, and projections of future water demands for the next 20 years, In addition, to <br />satisfy SBx7 -7 requirements, the section provides details of the City's SBx7.7 compliance method <br />selection, baseline water use calculation, and 2015 and 2020 water use targets. <br />There are 44,551 current customer active and inactive service connections in the City's water distribution <br />system with all existing connections metered. Approximately 66.8 percent of the City's water demand is <br />residential; commercial, including dedicated landscape, accounts for the remaining 33,2 percent of the total <br />demand. <br />The following table is a summary of the City's total water demand in for potable water (2015): <br />Use T e Additional Descri Lion Volume <br />Single Family 14,084 AFY <br />Multi - Family 10,399 AFY <br />Other (CII) Commercial /Institution /Industry 12,025 AFY <br />Landscape Large 147 AFY <br />TOTAL 36,656 AFY <br />The water demand projections included within the City's 2015 UWMP were an outcome of the Orange <br />County (OC) Reliability Study led by MWDOC. The OC Reliability study accounted for drought impacts <br />but excluded any changes as result of new conservation methods (new passive and active conservation as a <br />result of plumbing codes, water model efficiency landscape ordinance, etc.). However, the demand <br />projections account for passive savings in the future as described in the UWMP. <br />The following table is a projection of the City's water demand for the next 25 years: <br />Table 6: Projected Demands jor Potable Water (AFY) <br />Use Type <br />2015 <br />2020 <br />2025 <br />2030 <br />2035 <br />2040 <br />Single Family <br />14,084 <br />14,092 <br />15,137 <br />15,241 <br />15,237 <br />15,259 <br />Multi - Family <br />10,399 <br />10,405 <br />11,177 <br />11,254 <br />11?51 <br />11,267 <br />Other <br />12,025 <br />12,033 <br />12,925 <br />13,014 <br />13,010 <br />13,030 <br />Landscape <br />147 <br />148 <br />158 <br />160 <br />160 <br />160 <br />TOTAL <br />36,656 <br />36,678 <br />39,397 <br />39,669 <br />39,658 <br />39,716 <br />51 -'Td9 <br />
