The Hidden Hills development in Sonoma County, California, built in the 1960s, brought with it the establishment of the Riebli Mutual Water Company that included ownership by all 47 homeowners, two 600’ deep wells, a 40,000-gallon redwood storage tank, and an in-street distribution system. The Riebli Mutual Water Company is still the area’s water supply company.
The Riebli Mutual Water Company is committed to providing safe, high-quality water and services to our owners/members while maintaining a standard of excellence in customer service and environmental conservation.
