Urban Water Management Planning

Urban Water Management Planning Act

In 1983, the Urban Water Management Planning Act (UWMP Act) was established by Assembly Bill 797, and the passage of this law recognized that water is a limited resource and that efficient water use and conservation would be actively pursued throughout the State of California. The UWMP Act requires that water suppliers providing water for municipal purposes either directly or indirectly to more than 3,000 customers, or supplying more than 3,000 acre-feet of water annually, prepare and submit an Urban Water Management Plan (UWMP) to the California Department of Water Resources (DWR) every five years.

Urban Water Management Plans

UWMPs are required to support the water suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs. UWMPs must assess the reliability of water sources over a 20-year planning horizon during normal, single-dry, and multiple-dry years, describe management measures and water shortage contingency plans, report progress toward meeting conservation goals and targeted reduction in per-capita urban water consumption, and discuss the uses and planned uses of recycled water.

MSWD Urban Water Management Plans

Mission Springs Water District (MSWD) previously prepared and adopted 2005, 2010, and 2015 UWMPs. Copies of the past MSWD UWMPs can be found at DWR’s Water Use Efficiency Portal.

2020 Coachella Valley Regional Urban Water Management Plan

The six urban water suppliers in the Coachella Valley, (MSWD, Coachella Valley Water District, Coachella Water Authority, Desert Water Agency, Indio Water Authority, and Myoma Dunes Mutual Water Company) collaboratively prepared the 2020 Coachella Valley Regional UWMP, including regional and individual agency content and other necessary elements as set forth in DWR’s 2020 UWMP Guidebook. Each agency also prepared a Water Shortage Contingency Plan (WSCP) to describe the actions that could be taken during a water shortage to reduce demands. The 2020 Coachella Valley Regional UWMP and MSWD's WSCP were adopted by the Board of Directors on June 21, 2021, and submitted to DWR on July 1, 2021. Both documents can be accessed below and at DWR's Water Use Efficiency Portal.
