ROCKLAND SD 1 STP - Reedsville, Wisconsin Wastewater Treatment Plant

ROCKLAND SD 1 STP is a municipal wastewater treatment plant located at 409 Park Street in Reedsville, Wisconsin, within Manitowoc County. The facility serves a small population of 178 residents and is part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities. With a designed capacity of 94.64 million gallons per day and an actual discharge volume of 49.21 million gallons per day, the plant operates well below its capacity. As a US facility, it operates under an NPDES permit issued by the Wisconsin Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local water body that ultimately drains into Lake Michigan, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's location more than 10 km from the coast reduces direct marine impact, but its discharge still affects the sensitive Great Lakes ecosystem.

The plant discharges into a tributary of the Lake Michigan basin, which is part of the larger Great Lakes watershed. Lake Michigan supports a diverse ecosystem including native fish species and migratory birds. The region's cold-water streams are sensitive to nutrient loading, making secondary treatment important for protecting water quality downstream.
