Do I get any relief of sewer charges for outdoor summer usage?

The O’Fallon Utility Billing Department recognizes that customers use more water during the summer months due to outdoor watering.  The sewer averaging ordinance is a benefit given to relieve residential sewer customers of exorbitant summer bills due to heavy water usage.  All residential sewer customers are given sewer averaging for the months of June, July, and August.  A sewer average is calculated using the actual water consumption for the months of October through April.  The water consumption for these 7 months is averaged and that average is the basis for the amount of sewer consumption billed for the months of June, July, and August.  If the average consumption ends up being higher than the actual, the customer will be billed for the actual usage.

For new residences with no historical consumption data, the computer system will default 10,000 gallons as the basis for the average for sewer billing purposes.
