  • Description of Source Water System
    CHAPTER 2 DESCRIPTION OF THE SOURCE WATER SYSTEM 2.0 Description of the Source Water System During the last 100 years, the CSD’s water system has evolved into a very complex system. It is now estimated to serve a population of 1.4 million people spread out over 370 square miles (Table 2.1). The CSD treats imported raw water and local runoff water at three City WTPs which have a combined capacity of 378 MGD. The CSD treats water by conventional technologies using coagulation, flocculation, sedimentation, filtration and disinfection. Recently, all CSD water treatment plants have been modified to provide for the addition of fluoride to the potable water supply. To ensure safe and palatable water quality, the CSD collects water samples at its reservoirs, WTPs, and throughout the treated water storage and distribution system. The CSD’s use of local and imported water to meet water demand is affected by availability, cost, and water resource management policies. Imported water availability decreases the need to carry over local water for dry years in City reservoirs. CSD policy is to use local water first to reduce imported water purchases; this policy runs the risk of increased dependence on imported water during local droughts. Table 2.1 - City of San Diego General Statistics Population (2010) 1,301,621 Population (Estimated 2014) 1,381,069 Population percent change 6.1 Land Area Square Miles 370 Population Density per Square Mile 3733 Water Distribution Area Square Miles 403 Number of Service Connections (2015) 279,102 2.1 Water Sources (Figure 2.1) Most of California's water development has been dictated by the multi-year wet/dry weather cycles.
