West Basin’s 2020 Urban Water Management Plan (UWMP) provides a detailed summary of present and future water supplies and demands within the District’s service area, and assesses its ongoing water resource needs. Specifically, the UWMP provides water supply planning for a 25-year period in five-year increments and identifies water supplies needed to meet existing and future demands. West Basin’s 2020 UWMP updates the 2015 UWMP in compliance with requirements of the California Urban Water Management Planning Act and the California Water Code.
As a new requirement this year, West Basin developed a Water Shortage Contingency Plan (WSCP) that is separate from the UWMP and that demonstrates its ability to ensure reliable water supplies during various levels of water shortage, including catastrophic interruptions and emergency situations. The WSCP is a strategic planning document that provides West Basin with a set of structured guidelines to address temporary water shortages, allowing the District to efficiently manage any type of shortage situation with a flexible suite of response actions.
In addition, West Basin appendices to both the 2015 UWMP and 2020 UWMP to demonstrate consistency with the Delta Plan Policy WR P1, Reduced Reliance on the Delta Through Improved Regional Water Self-Reliance (California Code Reg., tit.23, §5003). The 2015 UWMP is being amended only to report reduced reliance on the Delta and this action is separate from adoption of the 2020 UWMP and adoption of the WSCP.
