Sonoma Valley County Sanitation District
Residential Sewer Estimator
|If you are a residential sewer and water customer, you can get an estimate of what your sewer charge might be by entering your average monthly winter water use into the estimator below.
PLEASE NOTE: This estimator is for single family dwellings, condominiums, and single mobile homes.
The District calculates residential sewer bills by using a volume-based rate structure. Thirty percent of your sewer bill is based on the amount of household water used during the winter months, beginning in December through February. The remaining seventy percent of the sewer bill is based on a fixed cost to cover operations and maintenance expenses related to keeping the sewage collection system and treatment facility updated to meet public health and environmental regulations. The rate structure does not apply to commercial customers, as they are charged based on a fixed rate structure.
Ways to lower your sewer bill
The following rebate and incentive programs may be available from the District, your water provider, and PG&E to help lower your sewer bill. Please contact your service provider for more information, eligibility, funding availability, and applications for the rebates before purchase.
