    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.

      Total Annual Sewer Bill
    You can get your average monthly winter water use from your water bills from last winter. Since your water bills show two months of water usage, you would need to enter half of the total gallons in the estimator below. If you don’t have your winter water bills, enter a typical residential average monthly winter water use of 4,420 gallons.

    How your sewer bill is calculated

    Comparison of Fixed Rate Billing Calculation and Volume Based Rate Billing Calculation

    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. Product specifications, requirements and restrictions vary by service provider.
