BREDA WWTP is a wastewater treatment plant located in Carroll County, Iowa, United States. It serves a small population of 467 residents, reflecting its role as a local municipal facility in a rural agricultural region. The plant is situated in Wheatland Township, approximately 15871 110th Street, and operates under the regulatory framework of the US Clean Water Act. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 427.75 units, with a current discharge volume of 325.55 units, indicating operational headroom. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and contributes to reducing nutrient loading in the Mississippi River watershed, which is critical for mitigating the Gulf of Mexico hypoxic zone.

The plant discharges into tributaries of the Raccoon River, which flows into the Des Moines River, a major tributary of the Mississippi River. The Mississippi River carries the effluent to the Gulf of Mexico. This watershed is part of the Corn Belt region, where agricultural runoff contributes to nutrient pollution. The plant's advanced treatment helps reduce nitrogen and phosphorus loads, supporting efforts to combat hypoxia in the Gulf.
