CONRATH STP - Secondary Wastewater Treatment Plant in Conrath, Wisconsin

CONRATH STP is a municipal wastewater treatment facility located on Vine Street in Conrath, a small village in Rusk County, Wisconsin. The plant serves a population of approximately 107 residents, reflecting the rural character of the area. It operates as a secondary treatment facility, which is the standard level required by the US Clean Water Act for most municipal plants. The plant's designed capacity is 34.07 million gallons, and it discharges 37.85 million gallons of treated wastewater annually. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids, meeting the effluent limits set by its National Pollutant Discharge Elimination System (NPDES) permit issued by the Wisconsin Department of Natural Resources. The treated effluent is discharged into a local water body, likely a tributary of the Chippewa River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in protecting local water quality in the Chippewa River basin, a region known for its forests, lakes, and recreational waterways.

The plant discharges into a small stream or river within the Chippewa River watershed, which drains into the Mississippi River and then the Gulf of Mexico. This region is part of the Upper Mississippi River basin, an ecologically significant area that supports diverse aquatic life and migratory birds. The secondary treatment process helps reduce nutrient loads and organic pollutants, protecting downstream water quality in the Chippewa River and its tributaries.
