North Fayette Township is responsible for the maintenance of the sanitary sewer system. Sewage is treated in one of two place depending on where you live. For the majority of residents that live north of Steubenville Pike, sewage is treated by the Moon Township Municipal Authority. All other Township residents are served by ALCOSAN (Allegheny County Sanitary Authority). Sewage Billing is calculated on water usage reported by Western Allegheny County Water Authority. The minimum usage is 9000 gallons per quarter at a rate of $7.50 per thousand gallon. This calculates the minimum quarterly bill to $67.50 with an additional $7.50 per 1000 gallons of water used over the minimum. The Township periodically does a rate study to make sure that the per-thousand gallon amount is not too high or low, based on charges received by the treatment plants.
