    About Urban Water Management Plans

    The 2010 Urban Water Management Plan update was required by the California Urban Water Management Planning Act and was completed on July 1, 2011. 

    The Water Agency is a wholesaler of potable water, serving nine primary municipal customers in Sonoma and Marin Counties.  The Water Agency’s Plan discusses and describes:

    • Existing water supplies and transmission system facilities;
    • Projected water demands in the Water Agency’s service area over the next 25 years;
    • Projected water supplies available to the Water Agency over the next 25 years, the reliability of that supply, and general schedules for water supply projects;
    • Climate change impacts to water supply;
    • Energy intensity;
    • Current and planned Water Agency water conservation activities;
    • A water shortage contingency analysis;  
    • And a comparison of water supply and water demand over the next 25 years under different hydrological assumptions (normal year, single dry year, multiple dry years).

    Schedule for preparation and approval of the Plan:

    • Coordinate with water retailers, city planners, other external stakeholders: Through May 2016
