One of the most important factors in water quality is its source: the purer the source, the better the water.  Our customers are fortunate because they enjoy a reliable water supply from two clean sources.  The District's primary source is purchased Russian River water from the Sonoma County Water Agency (SCWA).  This water is pumped over 30 miles in a below ground enclosed aqueduct.  The District's second source is local groundwater production, which is an important source for peak demand, emergency capacity and cost reductions.
