Bangor WWTP - Advanced Wastewater Treatment in Bangor, Wisconsin

Bangor WWTP is a municipal wastewater treatment facility located on State Highway 162 in Bangor, La Crosse County, Wisconsin. The plant serves a population of approximately 1,474 residents, classifying it as a small-scale treatment facility within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 586.74 thousand cubic meters per year and an annual discharge volume of 450.46 thousand cubic meters, the facility operates below its full capacity. As a US plant, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Wisconsin Department of Natural Resources, ensuring compliance with effluent limits. The treated effluent from Bangor WWTP is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's advanced treatment helps protect downstream water quality in the region, which supports diverse aquatic life and recreational uses. Its inland location reduces direct marine impact, but careful management is essential to prevent nutrient loading in the watershed.

The plant discharges into the La Crosse River watershed, a tributary of the Upper Mississippi River. The Mississippi River downstream supports a rich ecosystem, including migratory fish and waterfowl. Advanced treatment at this facility helps reduce nutrient loads that could contribute to hypoxia in the Gulf of Mexico, the ultimate destination of the basin's waters.
