CHANNAHON STP Wastewater Treatment Plant, Channahon, Illinois

CHANNAHON STP is a municipal wastewater treatment plant located in Channahon, Illinois, serving a population of about 6,200 residents. The facility is situated in the Midwest region of the United States, an area characterized by a continental climate with cold winters and warm summers. As a small-to-medium agglomeration, the plant is part of the local infrastructure managed by the village of Channahon. Under the U.S. Clean Water Act, municipal wastewater treatment plants are required to meet secondary treatment standards set by the Environmental Protection Agency (EPA). For a plant serving approximately 6,200 people, typical treatment includes biological processes to reduce organic matter and suspended solids. The plant's discharge is regulated through a National Pollutant Discharge Elimination System (NPDES) permit, which specifies effluent limits and monitoring requirements. The treated effluent from CHANNAHON STP is discharged into a local waterway that ultimately drains into the Illinois River basin. The Illinois River flows into the Mississippi River, which empties into the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in the larger Mississippi River watershed, which supports diverse aquatic life and is an important migratory corridor for birds and fish.

CHANNAHON STP discharges into a tributary of the Illinois River, which flows into the Mississippi River and eventually reaches the Gulf of Mexico. The Illinois River basin supports a variety of aquatic species and is an important ecological corridor. The plant's effluent must meet standards to protect downstream water quality, particularly in the context of nutrient pollution that contributes to the Gulf of Mexico hypoxic zone.
