The Wastewater Treatment Facility treats an average dry weather flow of 2.25 million gallons a day (MGD). After the waste stream has been treated to meet strict Illinois Environmental Protection Agency (IEPA) Discharge standards it is then discharged to the Fox River.
The excess solids that are removed during treatment are digested to stabilize their decomposition rate so it may be dewatered and used as fertilizer for crops such as corn, wheat, soybean and sod. The digested sludge must also meet strict IEPA/USEPA standards.
Annually we treat 900 million gallons of wastewater and generate approximately 6,000 cubic yards of solids.
