Proper treatment helps maintain water quality in the Kankakee River watershed and the larger Illinois River system.
Environmental context
The plant's treated effluent flows into tributaries of the Kankakee River, which joins the Illinois River and eventually the Mississippi River. This watershed supports diverse aquatic species and provides habitat for migratory birds. The region's flat terrain and agricultural land use make nutrient removal important to prevent downstream eutrophication in the Gulf of Mexico hypoxic zone.
