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.
