Wastewater Treatment Plant

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 plant at peak performance and be a good neighbor. Odor control is always a top priority and part of all operation and maintenance decisions.

The WWTP (formally known as WPCF) staff annually conducts tours for the children of G. Stanley Hall School or other groups. Requests for specific information regarding the WWTP operations can be made to the Division Manager of WWTP, at 630.942.1963, Monday - Friday from 7:00am - 3:30pm.

Plant Improvements

The Village of Glendale Heights will be commencing with the construction of the Digester No. 2 Rehabilitation Project at the Wastewater Treatment Plant located at 1401 Wayne Avenue, Glendale Heights, IL. The Digester No. 2 Rehabilitation Project is financed by the Clean Water State Revolving Fund (SRF). The SRF program is administered by the Illinois Environmental Protection Agency and receives a portion of its money to fund these types of projects from the U.S. Environmental Protection Agency.

The project includes improvements to the existing offline Aerobic Digester. The rehabilitation includes the installation of coarse air diffusers and a geodesic dome digester cover, and renovations to the treatment compartments. In addition, modifications will be made to the Tertiary Treatment Building to allow for the installation of new blowers for the aerobic digesters. The Sludge Processing Building will be retrofitted with a dewatered sludge pump, and new conveyors. The project also includes upgrades to the electrical and SCADA system located within the facility.

Once complete, it will improve water quality for area residents and businesses of the Village of Glendale Heights, Illinois. SRF programs operate in each state to provide communities the resources necessary to build, maintain, and improve the infrastructure that protects one of our most valuable resources: water.


The Illinois Association of Water Pollution Control has been presenting awards to deserving facilities for over 65 years. Nominees are presented to the Association by the Illinois Environmental Protection Agency. Facilities who provide exceptional service to their community as well as the wastewater community are recognized for their efforts with a nomination for Plant of the Year. In 2012, the Glendale Heights Wastewater Treatment Plant was nominated, along with four other Group-1 facilities, for Plant of the Year. This is a State-wide award and encompasses over 200 Group-1 facilities. On April 17th, 2013, at the Annual IAWPCO banquet in Springfield, Illinois, Glendale Heights was selected as the Plant of the Year. This is the first time the WWTP has won such an Award and the Village is extremely proud of the WPCF staff for their efforts.
