This division is responsible for the operation and maintenance of the Village's Wastewater Treatment Facility. Though not as visible as other public services, the wastewater treatment process is one of the most fundamental daily responsibilities. The facility normally processes 3.5 Million Gallons per Day (MGD) of wastewater, but is designed to process an average daily flow of 5.26 MGD and maximum daily flow of 10.52 MGD. The facility is also designed to process an additional 21 MGD of Excess Flow during wet weather/rain conditions. The facility is permitted by the Illinois Environmental Protection Agency (IEPA), to discharge treated wastewater to the East Branch of the DuPage River. The treated wastewater is actually cleaner than the receiving stream water! Biosolids or sludge produced by the facility is land applied on farm field as fertilizer to aid in preserving a clean environment.

The staff team works very diligently to keep the plan at peak performance and be a good neighbor. Odor control is always a top priority and part of all operation and maintenance decisions. The WPCF staff annually conducts tours for the children of G. Stanley Hall School or other groups. Requests for specific information regarding the WPCF operations can be made to the Division Manager of WPCF, at 630.942.1963, Monday - Friday from 7:00 a.m. - 3:30 p.m.
