How is sanitary sewer usage determined?

Charges for sanitary sewer usage are based on your water consumption. For residential customers, after you have lived at your address through the winter, the sewer charge will be based on your water consumption during the "winter quarter". Residential sewer customers are charged based on actual water usage for December, January and February (winter quarter) with the charge of the months of March through February based on the average usage for the previous winter quarter. If you have not lived at your current residence long enough to establish a winter quarter average, your sewage charge is based on the amount of water consumed each month. All non-residential customers are charged based on monthly water use.  more
