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 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:
The information collected from the submitted UWMPs is useful for local, regional, and statewide water planning.
DWR provides guidance for urban water suppliers by preparing an UWMP Guidebook, conducting workshops, developing tools, and providing program staff to help water suppliers prepare comprehensive and useful water management plans, implement water conservation programs, and understand the requirements in the California Water Code that regulate Urban Water Management Planning.
DWR then reviews the submitted plans to make sure they have addressed the requirements identified in the Water Code and submits a report to the Legislature summarizing the status of the plans for each five-year cycle.
Urban water suppliers submit their UWMPs to DWR through the secure WUEdata portal. Access into this portal is restricted to water suppliers, their authorized representatives, and DWR. DWR’s webinar on how to submit UWMPs through the WUEdata portal is available on the UWMP playlist of the DWR YouTube site.

Training Webinars. Between December 2020 and February 2021, DWR hosted a set of nine special topic training webinars. The training webinars are recorded and posted to the DWR YouTube page for public access. During the training webinars, we review planning tools, provide examples, and address participant questions. The following are focus topics from each webinar:
All 2020, 2015, 2000 and 2005 UWMPs submitted to DWR are available on the WUEdata Portal.
Aggregated data from the 2020 and 2015 tables of submitted UWMPs is available on the WUEdata portal.
Select data for the 2010 UWMPs may be downloaded from the California Natural Resources Agency (CNRA) Open Data Portal. For more information, see the 2010 UWMP data in the CNRA Open Data Portal.
For additional records (including those UWMPs prior to 2005), please submit requests for documents through the Public Records Request Portal.
As required by California Water Code, DWR must submit a report to the legislature describing the status of submitted UWMPs, statewide progress toward meeting the targeted 20% reduction in water use by 2020, and exemplary elements of submitted plans. These reports summarize the status of the planning cycle UWMP submittals received at the time of the preparation of the Legislative Report and they document key highlights in the UWMPs as determined by DWR.
To request a copy of a Legislative Report not listed above, please submit requests for documents through the Public Records Request Portal.
