2015 URBAN WATER MANAGEMENT PLAN <br />3.5 Recycled Water <br />The City receives recycled water from the Green Acres Project (GAP) that is used for non -potable <br />applications. More information concerning the City's recycled water usage can be found in Section 6. <br />3.6 Supply Reliability <br />3.6.1 Overview <br />Every urban water supplier is required to assess the reliability of their water service to its customers under <br />normal, dry, and multiple dry water years. The City depends on a combination of imported and local <br />supplies to meet its water demands and has taken numerous steps to ensure it has adequate supplies. <br />Development of numerous local augment the reliability of the imported water system. There are various <br />factors that may impact reliability of supplies such as legal, environmental, water quality and climatic <br />which are discussed below. The water supplies are projected to meet full -service demands; <br />Metropolitan's 2015 UWMP finds that Metropolitan is able to meet, full -service demands of its member <br />agencies starting 2020 through 2040 during normal years, single dry year, and multiple dry years. <br />Metropolitan's 2015 Integrated Water Resources Plan (IRP) update describes the core water resources <br />that will be used to meet full -service demands at the retail level under all foreseeable hydrologic <br />conditions from 2020 through 2040. The foundation of Metropolitan's resource strategy for achieving <br />regional water supply reliability has been to develop and implement water resources programs and <br />activities through its IRP preferred resource mix. This preferred resource mix includes conservation, local <br />resources such as water recycling and groundwater recovery, Colorado River supplies and transfers, <br />SWP supplies and transfers, in -region surface reservoir storage, in -region groundwater storage, out -of - <br />region banking, treatment, conveyance and infrastructure improvements. <br />3.6.2 Factors Impacting Reliability <br />The Act requires a description of water supply reliability and vulnerability to seasonal or climatic shortage. <br />The City's ability to meet supply demands is contingent upon its ability to maintain its water production <br />assets in proper working order. In addition, the following are some of the factors identified by Metropolitan <br />that may have an impact on the reliability of Metropolitan supplies. <br />3.6.2.1 Environment <br />Endangered species protection needs in the Delta have resulted in operational constraints to the SWP <br />system, as mentioned previously in the State Water Project Supplies section. <br />3.6.2.2 Legal <br />The addition of more species under the Endangered Species Act and new regulatory requirements could <br />impact SWP operations by requiring additional export reductions, releases of additional water from <br />storage or other operational changes impacting water supply operations. <br />arcadis.com <br />ETdo 3-16 <br />
