Winter Averaging


Residential volumetric wastewater rates are adjusted each October by calculating the average monthly water usage in a household during the months of mid-November through mid-February each year (when outdoor watering is at a minimum).  The number of gallons is divided by 1,000 and multiplied by the current volumetric rate.  This amount plus the base rate ($20.00/month) becomes the customer’s monthly rate for the coming year.

Example:         Average winter use = 8,000 gallons per month ÷ 1,000 = 8

8 x $1.75 / 1,000 gallons = $14.00 + $20.00 = $34.00/month

Customers with no usage history will be assigned a 6,000 gallon usage rate until a winter rate can be established.


Commercial volumetric wastewater rates are not subject to winter averaging but are based on actual water use each month.
