Kendall STP - Advanced Wastewater Treatment in Kendall, Wisconsin

Kendall STP is a municipal wastewater treatment facility located in Kendall, Wisconsin, a small community in Monroe County. The plant serves a population of 467 and operates with advanced treatment processes, ensuring high-quality effluent discharge. The plant has a designed capacity of 264.98 units and currently treats an average daily flow of 151.42 units. As an advanced treatment facility, it likely incorporates nutrient removal or other tertiary processes to meet stringent water quality standards. Under the US Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources. The treated effluent is discharged into a local water body, which ultimately drains into the Mississippi River basin. The plant plays a key role in protecting downstream water quality in the Driftless Area, a region known for its spring-fed streams and sensitive aquatic ecosystems.

The plant discharges into a tributary of the Baraboo River, which flows into the Wisconsin River and then the Mississippi River. The Driftless Area's karst topography makes groundwater and surface waters particularly vulnerable to contamination. Advanced treatment helps protect sensitive aquatic habitats, including coldwater fisheries and diverse macroinvertebrate communities.
