WADENA WW STABIL LAGOON - Wadena, Iowa Wastewater Treatment Plant

WADENA WW STABIL LAGOON is a municipal wastewater treatment facility located in Wadena, Iowa, a small community in Fayette County. The plant serves a population of 243 and operates as a stabilization lagoon system, providing secondary treatment to meet state and federal standards. As a secondary treatment facility, the plant uses biological processes to reduce organic matter and suspended solids before discharge. The designed capacity is 151.42 cubic meters per day, with an average discharge volume of 75.71 cubic meters per day. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources, ensuring effluent limits protect water quality. The treated effluent is discharged into nearby streams that drain into the Upper Mississippi River basin. This region supports diverse aquatic life and is part of a larger watershed that ultimately flows to the Gulf of Mexico. The plant's operation helps maintain local water quality and ecosystem balance.

The plant discharges into local waterways that are part of the Upper Mississippi River basin, which drains into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish and wildlife, including migratory birds and aquatic species. The secondary treatment process reduces nutrient and pollutant loads, helping to protect downstream water quality and prevent eutrophication in receiving waters.
