Sonoma County Water Agency (Sonoma Water) operates and manages Occidental County Sanitation District, Russian River County Sanitation District, Sonoma Valley County Sanitation District, and South Park County Sanitation District (Districts). 

Sonoma Water owns, operates, and manages Airport/Larkfield/Wikiup Sanitation Zone, Geyserville Sanitation Zone, Penngrove Sanitation Zone, and Sea Ranch Sanitation Zone (Zones).

The Districts and Zones offer a discount on Sewer Service Charges for low-income owner-occupied homes and for 501(c)(3) non-profit organizations that provide housing to low-income renters. 

REDUCED RATE: The reduced rate will be 50% of your total Annual Sewer Service Charge. 

Applications are due by July 10, 2023.  The application period has closed for 2023.

Anyone receiving the rate reduction and found to be in violation of program rules will be removed from the program and may be liable for repayment of the discount from the time that the discount was received.

Applicants will be notified of their eligibility. Applications are accepted until funds are exhausted and a waiting list will be maintained.

If your application is accepted, you will receive the sewer service charge rate reduction credit on your 2023-2024 property tax bill. If your 2023-2024 property tax bill has been paid in full, you will be issued a refund of the difference between the sewer service charge and the credit. 

You must renew your complete eligibility application every year.
