Whitecap Mountains SD STP - Town of Anderson, Wisconsin Wastewater Treatment Plant

Whitecap Mountains SD STP is a municipal wastewater treatment facility located in the Town of Anderson, Iron County, Wisconsin, United States. The plant serves a small population of 509 residents, reflecting its role in a rural or small community setting within the state's northern region. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants to reduce organic matter and suspended solids. The plant has a designed capacity of 291.48 units and currently discharges 75.71 units, indicating operational capacity well below its design limits. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Wisconsin Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent from the plant is discharged into a local water body, ultimately contributing to the Lake Superior basin via the Montreal River or other nearby watersheds. This region is ecologically sensitive, supporting coldwater fisheries and diverse aquatic life. The plant's secondary treatment helps protect downstream water quality in this northern Wisconsin ecosystem.

The plant discharges into a local water body that drains into the Lake Superior basin, likely via the Montreal River or similar tributaries. Lake Superior is the largest of the Great Lakes and supports a coldwater ecosystem with species such as lake trout and whitefish. The surrounding watershed includes forests and wetlands that provide important habitat and water filtration. Protecting water quality in this region is critical for maintaining the ecological health of the Great Lakes system.
