Regional Alliance

Page

In response to the Water Conservation Act of 2009, a Regional Alliance was created to comply with SB x7-7. The Regional Alliance includes the cities of Santa Rosa, Rohnert Park, Sonoma, Cotati, Petaluma, Town of Windsor and North Marin, Marin Municipal and Valley of the Moon Water Districts. The Regional Alliance has been formed pursuant to the Department of Water Resources Methodologies for Calculating Baseline and Compliance Urban Per Capita Water Use because all parties receive water from a common water wholesale supplier, Sonoma Water.

The Act set a goal of achieving a 20% reduction in statewide urban per capita water use by the year 2020 and requires urban water retailers to establish and report a 2020 urban per capita water use target and a 2015 interim water use target. The Regional Alliance’s 2015 interim target was set at 142 gallons per capita per day (GPCD).  In 2015, the Regional Alliance was able to achieve 100 GPCD, exceeding the interim target. The Department of Water Resources acknowledged the Regional Alliance addressed the reporting requirements.  The 2020 Target of 129 GPCD will be reported in the 2020 Urban Water Management Plan.
