Hauled Restaurant  Grease Trap Waste

The Downers Grove Sanitary District accepts hauled grease trap waste from haulers servicing restaurants. The hauled waste is accepted at our receiving station at the wastewater treatment center, where it is introduced into the sludge digestion process to produce more methane gas, a useful byproduct. There is a per gallon charge for this service, based on the volumetric capacity of the truck delivering the waste.

The District is working to make the treatment plant a Net-Zero Energy facility! Learn more about what we are doing to make this possible.

DuPage River Salt Creek Workgroup

The District is a founding member and active participant in the DuPage River Salt Creek Workgroup (DRSCW), which is dedicated to managing the valuable stream resources of the East and West Branches of the DuPage River and Salt Creek. While other wastewater treatment plants in Illinois have recently received phosphorus limits in their NPDES permits, the District was able to negotiate with IEPA a schedule that provides additional time before implementation of phosphorus limits in exchange for active participation in the DRSCW to better understand the impacts of nutrients in our watershed and to help fund restoration projects in our receiving stream, with the goal of achieving the most cost effective environmental improvements with limited available resources. For more information, visit www.drscw.org.

As part of the active participation in the DRSCW, the District’s NPDES permit requires the following reports to be posted on our website.
