CUBA CITY STP - Advanced Wastewater Treatment in Town of Benton, Wisconsin

CUBA CITY STP is an advanced wastewater treatment facility located in the Town of Benton, Lafayette County, Wisconsin, United States. The plant serves a population of 2,215 and operates as part of the municipal wastewater infrastructure for the surrounding community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,135.62 thousand cubic meters and an annual discharge volume of 567.81, the facility operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. Wisconsin's Department of Natural Resources administers these permits, ensuring compliance with water quality standards. The treated effluent from CUBA CITY STP is discharged into a local waterway that ultimately drains into the Mississippi River basin. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Upper Mississippi River, which supports diverse fish and wildlife populations and is an important migratory corridor for birds.

The plant discharges into a tributary of the Mississippi River basin, which flows south to the Gulf of Mexico. The Upper Mississippi River supports diverse aquatic life, including over 100 fish species, and is a critical migratory route for waterfowl. Advanced treatment at this plant helps reduce nutrient loading, which is essential for mitigating hypoxia in the Gulf of Mexico.
