Johnsonville Foods WWTP is an advanced wastewater treatment facility located in the Town of Sheboygan Falls, Sheboygan County, Wisconsin. The plant serves a small population of 129 and operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. As an advanced treatment plant, it goes beyond secondary treatment to remove additional nutrients and contaminants, reflecting the high standards expected for facilities in the Great Lakes region. The plant has a designed capacity of 984.20 volume units and a discharge volume of 847.93, indicating efficient operation within its capacity. Advanced treatment typically includes biological nutrient removal, filtration, or disinfection. The facility is subject to state-level oversight by the Wisconsin Department of Natural Resources, which enforces permit limits to protect receiving waters. The treated effluent from Johnsonville Foods WWTP ultimately drains into the Lake Michigan watershed, a vital freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps reduce nutrient loading, which is critical for preventing algal blooms and maintaining the ecological health of Lake Michigan and its tributaries.

The plant discharges into local streams that flow into the Lake Michigan basin, a major freshwater ecosystem supporting diverse fish populations and migratory birds. The watershed is sensitive to nutrient pollution, and advanced treatment helps mitigate eutrophication risks in nearshore areas and the broader lake.
