Our Water Future

Water Supply

Exploring Opportunities for our Water Future  

To enhance our community’s water supply resiliency, Santa Rosa Water is embarking on a study to identify opportunities to reduce vulnerability to water shortages and enhance long-term water supply reliability.

Santa Rosa Water will hold four community meetings to update the public and give the community opportunities to ask questions, make comments, and offer their ideas on the project over the next year. 

The next Community Meeting is Monday, June 26, 2023 from 5-7 p.m. Use the registration link below (Upcoming Meetings) and we’ll send you a meeting reminder and Zoom link a few days before the meeting.  

See “Past Meetings” for video recordings of previous public meetings, including the first community webinar held on October 26, 2022 and the second community webinar held on January 25, 2023.

Water Supply and Use

In average rainfall years, Santa Rosa has sufficient water supply to meet the needs of our growing community out to at least 2045 (projecting a 30% increase in population and accounting for higher density development). For a detailed analysis, please see Santa Rosa’s Urban Water Management Plan. During extended dry periods (such as 2020-2022), Santa Rosa addresses water shortages by implementing its Water Shortage Contingency Plan

Santa Rosa serves over 53,400 water connections, including about 49,000 connections for 175,755 residents and 4,400 connections for thousands of businesses, nonprofits, schools, public facilities, and other institutions. Each year, our community consumes about 5.6 billion gallons of water, which is used by customer of all types and by the city to flush water mains, test hydrants, repair system leaks, and fight fires. On average, the city purchases 93% of its drinking water supply from Sonoma Water (Russian River water) and produces about 7% of its drinking water from city wells. During extended dry periods, Sonoma Water may experience water shortages, which impacts Santa Rosa’s water supply. 

The city also recycles and reuses wastewater from Santa Rosa, Cotati, Rohnert Park, Sebastopol, South Park Sanitation District, and portions of unincorporated Sonoma County. The wastewater goes through four stringent treatment and disinfection steps at the Santa Rosa Regional Water Reuse facility, resulting in high quality recycled water that is safe for irrigation of landscapes, pastures, agricultural crops, vegetable and fruit crops, and for industrial processes and other (non-drinking water) uses. On average, 98% of the recycled water is used each year to irrigate approximately 6,400 acres of agricultural lands and urban landscaping, and for the Geysers Recharge Project to generate clean electricity.

Water Use Efficiency

While the Water Supply Alternatives Plan focuses on developing new water sources, the city recognizes the importance of using existing water resources wisely. With that in mind, Santa Rosa has worked for over 30 years to achieve significant improvements in water use efficiency. As a result, Santa Rosa used 14% less water in 2020 than in 1990, despite a 57% increase in population. On a per capita basis, average water use has decreased by 46% from 1990 to 2020. 

To achieve this, Santa Rosa’s Water Use Efficiency programs begin in 1991 and have been consistently funded and staffed since that time (in wet years and dry). To help water customers improve efficiency, the city offers free technical assistance, workshops, rebates, and incentives. For example, the City has supported the replacement of approximately 56,000 toilets with ultra-efficient low flow toilets and the conversion of over 3.75 million square feet of high-water use turf grass to low water use landscaping. The City has also been an early adopter of building standards, plumbing codes, and landscape requirements to ensure new development meets or exceeds strict State and local water use efficiency standards. 

In addition, the city adopted a Water Waste Ordinance in 1999 to prohibit waste of water due to plumbing leaks on the customer side and due to runoff from landscape irrigation. The city closely monitors its own water distribution system for leaks and makes repairs quickly to prevent waste.
