Union Center WWTP - Secondary Treatment Plant in Union Center, Wisconsin

Union Center WWTP is a municipal wastewater treatment facility located in Union Center, Wisconsin, United States. The plant serves a small population of 234 residents, reflecting its role in a rural community. It is situated in Juneau County, within the state of Wisconsin. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 151.42 million gallons per year, and it currently discharges 140.06 million gallons per year, indicating it operates below its capacity. The treated effluent is discharged into a local water body, contributing to the watershed of the Wisconsin River basin, which ultimately flows into the Mississippi River. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources, ensuring compliance with water quality standards to protect downstream aquatic ecosystems.

The plant discharges into a receiving water body within the Wisconsin River watershed, which drains into the Mississippi River and eventually the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating eutrophication risks in downstream waters.
