The Sonoma County Water Agency manages and operates eight different sanitation districts and zones throughout Sonoma County. High-quality tertiary treated recycled water is an important source of water and its use offsets potable water demands.
The Sonoma County Water Agency (Water Agency) will hold a series of community meetings to discuss a proposed sewer lateral ordinance aimed at preventing sewer overflows that occur during heavy rains. The ordinance would apply to the Russian River and Occidental County Sanitation Districts, and the Airport/Larkfield/Wikiup, Geyserville, and Sea Ranch Sanitation Zones, all of which are operated by the Water Agency.
