The City of Warrenville does not have its own wastewater treatment plant. Wastewater, which comes from sinks, toilets, baths, and washing machines, must be treated by a wastewater treatment plant to remove pollutants. Warrenville has contracted with the City of Naperville to have our wastewater treated by their facility.

Wastewater drains from a building into the City’s sanitary sewer system and is eventually transported to the City of Naperville’s facility. The charge for this service is passed on to the resident in their sewer bill. A property’s meter gauges the amount of wastewater exiting the building. Utility Division personnel are available on a 24-hour basis for emergencies regarding sanitary sewer problems. Current charges for wastewater treatment are as follows.

Sewer Base Charge: varies depending on the Meter size.

Consumption Charge: $2.23 every thousand gallons
