Winfield City Lake WWTP - Secondary Treatment Plant in Winfield, Kansas

Winfield City Lake WWTP is a municipal wastewater treatment facility located in Winfield, Cowley County, Kansas. The plant serves a small population of 40 and has a designed capacity of 15.14 million gallons per day, with a discharge volume matching that capacity. It is situated inland, far from coastal areas, and treats wastewater for the local community. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for most municipal facilities. Under the National Pollutant Discharge Elimination System (NPDES), permits are issued by the state or EPA to ensure compliance with water quality standards. For a plant of this small scale, secondary treatment effectively removes organic matter and suspended solids before discharge. The treated effluent is discharged into a local water body, likely a stream or lake within the Arkansas River basin. The plant's operations help protect downstream water quality and aquatic ecosystems in the region. Proper treatment reduces nutrient loading and prevents pollution in the surrounding watershed.

The plant discharges into a local water body that is part of the Arkansas River watershed, which flows through Kansas and Oklahoma before joining the Mississippi River. The downstream environment includes agricultural and natural areas where water quality is important for irrigation, recreation, and wildlife. The plant's secondary treatment helps control organic pollutants and suspended solids, supporting the ecological health of the receiving waters.
