<br />2. Projected values per the City of Santa Ana 2015 UWMP, Table 3-8.
<br />In all cases considered (normal year, single -dry year, and multiple dry -year), the available supply will meet
<br />projected demand due to diversified supply and conservation measures.
<br />4.5 City of Santa Ana Water Infrastructure
<br />The City of Santa Ana (Water System Number CA3010038) owns and operates an extensive network of
<br />pipes, pumps, and reservoirs, delivering water to its service area. The UWMP and the City's 2017 Water
<br />Master Plan both describe the City's water infrastructure.
<br />4.5.1 Overall City Infrastructure
<br />The City provided 36,656 AF of water to 44,610 municipal connections in 2015. The City maintains
<br />approximately 480 miles of transmission and distribution mains, 10 reservoirs with a cumulative storage
<br />capacity of 49 MG, seven pumping stations, 21 groundwater wells, four pressure regulating stations and
<br />seven import water connections. Portions of the City infrastructure are aged and require replacement.
<br />The Master Plan outlines recommended Capital Improvement Program (CIP) improvements.
<br />Fourteen of the City Wells pump into surface reservoirs with booster stations pumping the water into the
<br />distribution system. The remaining seven wells pump directly into the City's distribution system. Water
<br />pumped from all of the wells is naturally filtered as it passes through underlying aquifers of sand, gravel,
<br />and soil. This well water only requires disinfectant treatment for system distribution.
<br />The City maintains seven imported water connections to receive water through MWD's Orange County
<br />and East Orange County Feeder pipelines. Seven metered connections with a total capacity of 60,580
<br />gallons per minute (gpm) transferwater into the City's distribution system.
