Sewer service fees appear on Marin County Property Tax Statements. The fees charged for residential dwellings and businesses are calculated differently. The residential rate, which is consistent through most of the Ross Valley, is a fixed fee regardless of the size of the home. Business fees are based on water usage. The more water that is used by a business, the more wastewater created for collection by the district and treatment by the sewage treatment plant.
Ross Valley Residential Sewer Rate: $638/year*
Larkspur Residential Sewer Rate: $864/year*
*IMPORTANT: You should 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.
