WESLEY WWTP - Kossuth County, Iowa Wastewater Treatment Plant

WESLEY WWTP is a municipal wastewater treatment facility located in Kossuth County, Iowa, United States. The plant serves a small population of 390 residents, reflecting its role in a rural agricultural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 227.12 cubic meters per day and an average discharge volume of 189.27 cubic meters per day, the facility operates below its capacity, indicating adequate headroom for current demand. The plant's discharge is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Iowa Department of Natural Resources. The treated effluent is discharged into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. The plant's location in the Upper Mississippi River watershed means its discharge contributes to the nutrient load in a region known for agricultural runoff, making effective treatment important for downstream water quality and aquatic ecosystems.

The plant discharges into tributaries of the Upper Mississippi River, which flows south to the Gulf of Mexico. This region is part of the Mississippi River Basin, a major agricultural watershed where nutrient pollution from fertilizers contributes to the Gulf of Mexico hypoxic zone. The plant's secondary treatment helps reduce organic pollutants and suspended solids, supporting the health of local streams and downstream aquatic life.
