Brownsville WWTP - Advanced Wastewater Treatment in Brownsville, Wisconsin

Brownsville WWTP is a municipal wastewater treatment plant located at 416 Prospect Avenue in Brownsville, Wisconsin. The facility serves a population of 594 and is situated in Dodge County, within the state's inland region. As a small-scale plant, it plays a vital role in managing local wastewater for this rural community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 473,180 gallons per day and an actual discharge volume of 200,630 gallons per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants are required to meet National Pollutant Discharge Elimination System (NPDES) permit standards, which are enforced by the Wisconsin Department of Natural Resources. The treated effluent is discharged into a local waterway that ultimately drains into the Rock River basin, which flows southward to the Mississippi River. This connection to the Mississippi River system means the plant's discharge contributes to the water quality of a major interstate watershed, supporting diverse aquatic life and downstream ecosystems.

The plant's discharge enters a tributary of the Rock River, which flows through southern Wisconsin and northern Illinois before joining the Mississippi River. The Rock River basin supports a variety of fish species and provides habitat for migratory birds. The Mississippi River downstream is a critical ecological corridor, and nutrient loading from wastewater can contribute to algal blooms and hypoxia in the Gulf of Mexico. Advanced treatment at this plant helps reduce such impacts.
