Buffalo Center WWTP - Secondary Treatment in Buffalo Center, Iowa

Buffalo Center WWTP is a municipal wastewater treatment facility located in Buffalo Center, Winnebago County, Iowa. The plant serves a small community of approximately 1,081 people, reflecting its role in managing domestic wastewater for this rural Midwestern town. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal facilities. With a designed capacity of 605.66 m³/day and an average daily discharge of 378.54 m³/day, the plant operates below its capacity, indicating adequate headroom for current flows. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Iowa Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent is discharged into local streams that drain into the Upper Iowa River watershed, ultimately reaching the Mississippi River. This connection to the Mississippi River basin highlights the plant's role in protecting downstream water quality, including the Gulf of Mexico, where nutrient pollution is a concern. The plant's secondary treatment helps reduce organic pollutants and suspended solids, contributing to the ecological health of the region's aquatic ecosystems.

The plant discharges into small tributaries of the Upper Iowa River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports diverse aquatic life and is part of a larger system affected by nutrient runoff. The plant's secondary treatment helps mitigate local eutrophication risks and protects downstream habitats.
