Santa Ana 2020 Urban Water Management Plan <br />arcadis.com <br />6-4 <br />Figure 6-1: City’s Projected Water Supply Sources (AF) <br />Imported Water <br />The City supplements its local water supply with imported water purchased from MET. In FY 2019-20, <br />the City relied on approximately 7,649 AFY – approximately 23% of the City’s water supply portfolio for <br />FY 2019-20 – of imported water from MET to meet its demands. MET’s principal sources of water are the <br />Colorado River via the Colorado River Aqueduct (CRA) and the Lake Oroville watershed in Northern <br />California through the SWP. For Orange County, the water obtained from these sources is treated at the <br />Robert B. Diemer Filtration Plant located in Yorba Linda. Typically, the Diemer Filtration Plant receives a <br />blend of Colorado River water from Lake Mathews through the MET Lower Feeder and SWP water <br />through the Yorba Linda Feeder. The City currently maintains seven imported water connections to the <br />MET system. <br />In December 2002, the City entered into a 10-year water purchase agreement with MET. This water <br />purchase agreement is a 10-year commitment to purchase a minimum quantity of water on an annual <br />basis and a minimum quantity of water over the course of the 10-year commitment. In return, the City is <br />able to purchase a greater percentage of MET water at a lower, Tier 1 rate. This purchase agreement <br />was renewed, and the current ten-year term is effective January 1, 2015 through December 31, 2024. <br />The City’s annual purchase commitment average is 8,086 AF, with a maximum average annual value set <br />at 19,617 AF.
