Wastewater averaging is a way for you to save money. Wastewater averaging takes place during the late fall / winter months and determines a cap on the volume of wastewater you will be billed for each month for the next year. 

Calculating Wastewater Average 

Wastewater averaging is calculated from mid-Nov. to mid-Mar. when most of the water goes directly into the sanitary sewer system versus being used for outdoor watering.

Residential Customers

To calculate your wastewater average you must have at least 60 consecutive days of water use with a minimum of 100 gallons used per billing period.

If less than 100 gallons is billed for two or more months of the averaging period, the wastewater average will be set at a default of 5,000 gallons.


Non-residential Customers

New non-Residential customers wastewater averaging is determined by:

  • Previous non-residential customer’s wastewater average, or
  • Gallon for gallon
