About Urban Water Management


DWR has begun preparations for the 2015 round of Urban Water Management Plans (UWMPs). Click here for the 2015 UWMP webpage.

What are Urban Water Management Plans?

Urban Water Management Plans (UWMPs) are prepared by California's urban water suppliers to support their long-term resource planning, and ensure adequate water supplies are available to meet existing and future water demands.

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 assess the reliability of its water sources over a 20-year planning horizon, and report its progress on 20% reduction in per-capita urban water consumption by the year 2020, as required in the Water Conservation Bill of 2009 SBX7-7.

The plans must be prepared every 5 years and submitted to the Department of Water Resources (DWR). DWR staff then reviews the submitted plans to make sure they have completed the requirements identified in the Water Code, Sections §10608– 10656, then submits a report to the Legislature summarizing the status of the plans.

For each round of UWMPs, DWR provides guidance for urban water suppliers. This includes preparation of a Guidebook, workshops, and program staff to assist in preparing comprehensive and useful water management plans, implementation of water conservation programs, and understanding the requirements of the Act.

2015 Urban Water Management Plans – Listening Session

DWR is beginning preparation of guidance to urban water suppliers for the 2015 round of UWMPs. As a first step in the process, DWR will host a listening session, via webinar, on September 3, 2014, from 9:00-11:00 a.m. to gather input from interested stakeholders on the guidance provided in the 2010 version of the Urban Water Management Plan Guidebook and comments and suggestions for the 2015 update to the Guidebook.

During the listening session, DWR will also present an overview of the timeline and process for the guidebook update. Comments, questions, and suggestions will be taken from the listening audience, and written comments will also be accepted through September 10, 2014 to

DWR will also be forming a 2015 UWMP Guidebook Advisory Committee. The committee will likely meet through webinars that will be open to the public. A schedule of meetings will be posted to the Urban Water Management webpage.

The public draft for the 2015 UWMP guidebook is slated for release in early August 2015. A public hearing on the draft guidebook will also be scheduled in August. Release of the final guidebook is expected in September 2015.

2010 Urban Water Management Plans

2010 UWMP Data

DWR and urban water suppliers have entered 2010 urban water management plan data into a database using the DWR On-Line Submittal Tool (DOST). Follow this link to the 2010 Data Page that provides links to a number of queries and reports developed from this dataset.

Currently not all of the urban water management plan data has been entered into the database. Each report provided will list the date it was produced and the number of plans from which the query pulled data. The database also contains data from plans that have not yet been reviewed by DWR.

DWR’s Report to the Legislature on 2010 UWMPs

The Urban Water Management Planning Act requires DWR to submit a report to the legislature summarizing the status of submitted urban water management plans.

Part 1 of the Legislative Report on 2010 UWMPs was submitted to the Legislature in June of 2012 and can be found here.

Part 2 of the Legislative Report on 2010 UWMPs is currently under preparation and will be posted to this page upon completion.
