COLFAX STP - Colfax, Illinois Wastewater Treatment Plant

COLFAX STP is a municipal wastewater treatment facility located in Colfax, McLean County, Illinois. The plant serves a population of approximately 877 residents, reflecting a small community in the Midwestern United States. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level for small to medium communities in the US. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 416.39 and a current discharge volume of 302.83, indicating it operates below its full capacity. This suggests the facility has room for future growth or seasonal variations. The treated effluent from COLFAX STP is discharged into a local water body, likely a stream or river within the Mississippi River Basin, as Illinois drains into the Mississippi River system. The plant's operations help protect downstream water quality and aquatic ecosystems, supporting the overall health of the watershed.

COLFAX STP discharges into a local water body that is part of the Mississippi River Basin, ultimately flowing into the Gulf of Mexico. The plant's secondary treatment reduces organic pollutants and suspended solids, protecting the downstream aquatic environment. The region's agricultural landscape contributes nutrient runoff, making the plant's role in controlling nutrient loads important for preventing eutrophication in receiving waters.
