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.

Comparison of Fixed Rate Billing Calculation and Volume Based Rate Billing CalculationHow your sewer bill is calculated

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.
