BELOIT Town of STP - Municipal Wastewater Treatment in Town of Beloit, Wisconsin

BELOIT Town of STP is a municipal wastewater treatment plant located at 3631 South Walters Road in the Town of Beloit, Rock County, Wisconsin. Serving a population of about 7,226, the facility is part of the region's wastewater infrastructure managed under state and federal regulations. As a US-based plant, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. For a community of this size, secondary treatment is typically required to reduce organic pollutants and suspended solids before discharge. Regulatory standards ensure compliance with water quality goals. The plant discharges treated effluent into local waterways that drain into the Rock River basin, which flows southward to the Mississippi River. This watershed supports diverse aquatic life and provides water for downstream communities. Proper treatment helps protect the ecological health of the Rock River and its tributaries.

The plant's discharge enters the Rock River watershed, which flows into the Mississippi River and ultimately the Gulf of Mexico. This region supports a variety of fish and wildlife species, and the river is used for recreation and drinking water. Effective wastewater treatment is crucial to prevent nutrient pollution that could contribute to hypoxia in the Gulf.
