The California Water Code requires all urban water suppliers that provide water for municipal purposes either directly or indirectly to more than 3,000 customers (or supply more than 3,000 acre-feet of water annually) to prepare an Urban Water Management Plan (UWMP) and Water Shortage Contingency Plan (WSCP).
The plans describe and evaluate sources of supply, reasonable and practical efficient uses, reclamation, and demand management activities. The components of a plan may vary according to an individual community or area’s characteristics and its capability to efficiently use and conserve water. The plans address measures for residential, commercial, governmental, and industrial water demand management.
Our Urban Water Management Plan is a foundational document that supports our long-term water resource planning to help supply our customers with adequate water to meet current and future demand.

The current UWMP and WSCP for all Districts are listed below. Please note that the WSCP is incorporated as an Appendix of each UWMP.
