2015 URBAN WATER MANAGEMENT PLAN 3.5 Recycled Water The City receives recycled water from the Green Acres Project (GAP) that is used for non - potable applications. More information concerning the City's recycled water usage can be found in Section 6. 3.6 Supply Reliability 3.6.1 Overview Every urban water supplier is required to assess the reliability of their water service to its customers under normal, dry, and multiple dry water years. The City depends on a combination of imported and local supplies to meet its water demands and has taken numerous steps to ensure it has adequate supplies. Development of numerous local augment the reliability of the imported water system. There are various factors that may impact reliability of supplies such as legal, environmental, water quality and climatic which are discussed below. The water supplies are projected to meet full-service demands, Metropolitan's 2015 UWMP finds that Metropolitan is able to meet, full- service demands of its member agencies starting 2020 through 2040 during normal years, single dry year, and multiple dry years. Metropolitan's 2015 Integrated Water Resources Plan (IRP) update describes the core water resources that will be used to meet full- service demands at the retail level under all foreseeable hydrologic conditions from 2020 through 2040. The foundation of Metropolitan's resource strategy for achieving regional water supply reliability has been to develop and implement water resources programs and activities through its IRP preferred resource mix. This preferred resource mix includes conservation, local resources such as water recycling and groundwater recovery, Colorado River supplies and transfers, SWP supplies and transfers, in- region surface reservoir storage, in- region groundwater storage, out -of- region banking, treatment, conveyance and infrastructure improvements. 3.6.2 Factors Impacting Reliability The Act requires a description of water supply reliability and vulnerability to seasonal or climatic shortage. The City's ability to meet supply demands is contingent upon its ability to maintain its water production assets in proper working order. In addition, the following are some of the factors identified by Metropolitar that may have an impact on the reliability of Metropolitan supplies. 3.621 Environment Endangered species protection needs in the Delta have resulted in operational constraints to the SWP system, as mentioned previously in the State Water Project Supplies section. 3.6.2.2 Legal The addition of more species under the Endangered Species Act and new regulatory requirements could impact SWP operations by requiring additional export reductions, releases of additional water from storage or other operational changes impacting water supply operations. arcad1s.com 75E -50 3 -16
