Urban Water Management Plan

The Urban Water Management Plan (UWMP) and Water Shortage Contingency Plan (WSCP) are important long term planning documents for the District and are updated at least every five years in accordance with the Urban Water Management Planning Act (California Water Code §10610 –10657).

In the UWMP, EBMUD assesses water supplies against expected water demands for a 25-year planning horizon and outlines actions to to address future uncertainties, including maintaining a resilient water supply portfolio, expanding recycled water use, and continuing water conservation programs.

The WSCP provides a framework to guide EBMUD’s response to potential water shortages and evaluates a range of scenarios designed to test assumptions and explore changes such as climate impacts and other uncertainties. Together, these plans form a key part of EBMUD’s long‑range efforts to ensure reliable water service, particularly during multi‑year droughts. 

The Water Supply Management Program (WSMP) 2040 served as an earlier program‑level assessment of long‑term water supply needs and potential dry‑year strategies. Initially approved in 2009 and revised in 2012 following additional CEQA review, the WSMP 2040 informed subsequent planning efforts. Its core concepts have since been incorporated into and superseded by the UWMP. Further information on the WSMP can be found here.

The UWMP 2020 and the WSCP 2020 (Attachment 1 in the UWMP) were adopted by the EBMUD Board of Directors on June 22, 2021. They can be accessed electronically using the link below.
