Urban Water Management Plans

Urban Water Management Plans are prepared by urban water suppliers every 5 years to support long-term resource planning and water supply sustainability.

Urban Water Management Plans (UWMPs) are prepared by urban water suppliers every five years. These plans support the suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs. The information collected from UWMPs is useful for local, regional, and statewide water planning.

 

The requirements for UWMPs are found in two sections of California Water Code, §10610-10656 and §10608.  Every urban water supplier that either provides over 3,000 acre-feet of water annually, or serves more than 3,000 urban connections is required to submit an UWMP.

 

Within UWMPs, urban water suppliers must include the following:

 

  • An assessment of the reliability of water sources over a 20-year planning time frame
  • A description of demand management measures
  • A water shortage contingency plan
  • A discussion of the use and planned use of recycled water

DWR assists suppliers in developing their UWMPs by providing a UWMP Guidebook, video workshops and the support of program staff. Once the UWMP is submitted, DWR reviews the plans to ensure they have addressed the requirements of the Water Code. At the end of each reporting cycle, DWR submits a report to the Legislature summarizing the status of the plans for each five-year cycle. 

2025 Urban Water Management Plans

 

UWMPs for the 2025 cycle must be adopted and submitted by July 1, 2026. UWMPs must be submitted into DWR within 30 days of adoption via the WUEdata Portal. Access to this portal is restricted to water suppliers, their authorized representatives, and DWR.  

UPDATE: The Final 2025 Urban Water Management Plan (UWMP) Guidebook is now available and includes updates to improve clarity and provide additional guidance.
