202S WATER SHORTAGE CONTINGENCY PLAN <br /> MAY 2026/FINAL DRAFT/CAROLLO <br /> This section documents the decision-making process required for formal approval of the City's AWSDA <br /> determination of water supply reliability each year and the key data inputs and the methodologies used <br /> to evaluate the water system reliability for the coming year,while considering that the year to follow <br /> would be considered dry. <br /> 3.2.1 Decision-Making Process <br /> The following decision-making process describes the functional steps that the City will take to formally <br /> approve the AWSDA determination of water supply reliability each year. <br /> 3.2.1.1 City Steps to Approve the AWSDA Determination <br /> The AWSDA will be predicated primarily on the OCWD Basin Production Percentage (BPP) and secondarily <br /> on MET's AWSDA outcomes.

The BPP is set uniformly for <br /> all Producers by the OCWD Board of Directors on an annual basis. Based on the projected water demand <br /> and modeled water supply, over the long-term, OCWD anticipates sustainably supporting a BPP of <br /> 85 percent; however,volumes of groundwater and imported water may vary depending on OCWD's actual <br /> BPP projections.A supply reduction that may result from the annual BPP projection will be included in the <br /> AWSDA. <br /> While the City's primary source of water is OCWD groundwater, any remaining water to meet retail <br /> demands comes from recycled water and the purchase of imported water from MET.As a direct MET <br /> member, the AWSDA will be predicated on MET's WSDM supply demand tracking, which is reported <br /> CITY OF SANTA ANA <br />
