Rates

Ross Valley Sanitary District collects a Sewer Service Charge on each property that is connected to the District’s sewer system. Property owners receive the annual sewer service charge on their property tax bill, which is collected by Marin County and appears on Marin County Property Tax Statements.

Be aware that while your sewer fee appears as one charge on your tax bill, the fee actually funds two separate and independent organizations: Ross Valley Sanitary District, which provides the collection system that delivers wastewater to the treatment plant, and Central Marin Sanitation Agency, which treats wastewater before pumping it into the San Francisco Bay.

Please note: not all parcels with an address in Larkspur pay the "Larkspur Rate". Parcels north of Corte Madera Creek (e.g., in Greenbrae, Drake’s Landing and Larkspur Landing) and in Riviera Circle pay the Ross Valley rate and a portion of their property tax goes to the District for its capital program funding.

In 2019, the District was at the end of a five-year period of scheduled sewer rate increases of been 6.5% to 7.5% per year since 2014. These rate increases made up for previous years when no rate increases occurred but regulatory requirements for strict quantities of sewer rehabilitation were mounting. The District has also been under regulatory order by the San Francisco Bay Regional Water Quality Control Board over the past five years to implement timely maintenance of our sewer system and to make systematic infrastructure upgrades to achieve long-term reliability. 

In order to continue to meet these goals, the RVSD Board of Directors held a Public Hearing on Proposed Rates for Sewer Service Charges in June 2019 and adopted the new Sewer Service Charges shown below. Rates do increase over the next five years, but at an average rate that is lower than the previous five years. The new rates are designed to meet the demands of regulatory requirements and community standards for well ­maintained and high-performing sewer system operation.
