Technical Proposal and Evaluation Criteria Executive Summary March 27, 2019, Mr. Don Bunts, Deputy General Manager, Santa Margarita Water District, Rancho Santa Margarita, Orange County, California Work Proposed: The proposed Las Flores Enhanced Water Reliability Project (Project) will expand the Santa Margarita Water District’s (SMWD/District’s) recycled water system to provide recycled water supply, in place of potable water supply, for existing landscape irrigation uses in the unincorporated community of Las Flores, Orange County, California. The proposed Project includes installing approximately 3,800 linear feet of 16-inch pipe and 5,200 linear feet of 8-inch pipe in residential streets and easements through previously disturbed open space. The Project will upgrade an existing out-of-service District pump station and repurpose an existing force main approximately 3,600 linear feet long. The Project will permanently convert a total of 209 acre-feet per year (AFY) of irrigation water demand from potable to recycled water and serves as the first phase of a larger project that will provide up to an additional 1,000 AFY of recycled water to irrigation users in the adjacent City of Rancho Santa Margarita. Therefore, the total potential Project water savings is 1, 209 AFY. The District is proposing the Project as part of its long-term resilience to drought plan by 1) improving infrastructure for enhanced water reliability and flexibility in times of drought, 2) permanently eliminating 209 AFY immediately, and 1,000 AFY in the future, of imported water demands by converting the services to recycled water, and 3) benefitting fish, wildlife, and the environment by allowing more imported water to stay at its source to support Bay-Delta and Colorado River habitats. 79% of the District's total water supply is purchased surface water imported by the Metropolitan Water District of Southern California (MWD) via the Municipal Water District of Orange County (MWDOC). MWD's imported water sources are the Colorado River Aqueduct (CRA) and the State Water Project (SWP), which draws water from the San Francisco-San Joaquin Bay Delta (Bay-Delta). The District is in the south Orange County region, which has limited local water supplies and relies on imported water sources to meet approximately 90% of potable water demand. Overall, the Project will expand upon the District's efforts to promote water use efficiency by ultimately better managing 1,209 AFY of water. Following the July 2019 funding award announcement, it is anticipated that the funding agreement will be signed by October 1, 2019. The Project will be completed within 3 years by October 1, 2022. The Project is not located on a federal facility. Background Data Water Sources, Supplies, and Demands. The District relies on a combination of imported water, urban runoff, purchased groundwater, and recycled water to meet its water needs. The proposed Project will distribute recycled water, which the District anticipates being obtained from Oso Creek, 3A, or Chiquita Water Reclamation Plants, or from urban runoff captured by the District. The District works with two primary agencies, MWD and MWDOC, to ensure a safe and reliable drinking water supply that will continue to serve the community in periods of drought and shortage. The sources of imported water supplies for the District include water from the CRA and the SWP provided by MWD and delivered through MWDOC. MWD provides imported water to 20 million people (approximately half of the state’s population). MWDOC provides imported water from MWD to over 3 million people in Orange County. Water from both sources is treated at either the Diemer Filtration Plant in Yorba Linda or the Baker Treatment Plant in Irvine prior to delivery to the District. Over the past 5 years, the District’s total water supply included approximately 79% imported water. The District seeks to minimize its imported water usage by developing alternative domestic water supplies such as recycled water. MWD provides a majority of the District’s supply in the form of imported potable water at WaterSMART Drought Response Program: Drought Resiliency Projects FY 2019 Application 3 a total of approximately 23,432 AF in FY 2018, while recycled water supplies total approximately 9,076 AF in FY 2018. Table 1, Santa Margarita Water District Water Supplies, Actual and Projected (AF), lists the actual sources and volume of water for 2018. The demand and supplies shown herein also include recycled water supplies that are available to the District. Currently, five agencies, including the District,
