Winter Averaging  is a program that calculates residential sewer flow charges based on water consumption during the winter when residential customers historically use the least amount of water.

Residential customers' sanitary sewer volume charges are billed based on winter water consumption.  This billing method averages water consumption for the billing months of January, February and March to calculate a value that is then applied to sewer billing starting in April and for the rest of the year through the next April.  The average functions as a cap on sewer consumption. 

Customers that have consumption below the average are billed at the actual consumption.  Customers that exceed the average are billed at the average.  The average is reset each April with a new value based upon the latest winter data. 

By fixing leaks and keeping water usage low during the months when your average is being calculated, you can help reduce your sewer volume costs all year. We recommend waiting until after your average is calculated (April or later) to fill a pool or irrigate extensively.

Residential sewer customers automatically get to take advantage of this new program - you don’t need to call us to enroll.
