Where Our Water Comes From

Santa Rosa's primary source of water is from the Russian River supplied by the Sonoma County Water Agency (Water Agency). The Water Agency pumps water that is naturally filtered through rock, sand and gravel from wells about 100 feet below the river bed and provides that water to retail water suppliers, including Santa Rosa, throughout Sonoma County and North Marin. Santa Rosa Water also owns and operates two groundwater production wells to supplement water received from the Water Agency. Santa Rosa is very fortunate because the Russian River and our groundwater wells produce high quality drinking water that does not face water quality concerns that affect many public water systems throughout the United States.

Santa Rosa provides water to over 53,000 customers in Santa Rosa; 91% are residential and 9% are commercial customers. To ensure adequate water supplies are available for current and future water demands under varying water supply conditions, Santa Rosa Water has an aggressive water conservation program and provides recycled water for urban and agricultural irrigation to reduce potable water demands.
