The Castle Rock County Water District (CRCWD) is a small, independent water district serving rural properties in both the City of Walnut Creek and the surrounding unincorporated area. Formed in 1955, CRCWD serves 54 customers by distributing and selling untreated water for landscape irrigation and some commercial uses. CRCWD purchases untreated water from Contra Costa Water District (CCWD) pumped from an open canal that crosses Oak Grove Road. Meter readings and billings are performed on a quarterly calendar basis.
