Centerville WWTF - Secondary Wastewater Treatment Plant in Centerville, Missouri

Centerville WWTF is a municipal wastewater treatment facility located in Centerville, Reynolds County, Missouri. The plant serves a small population of 271 residents and operates under secondary treatment standards, which are typical for small communities in the United States. The plant has a designed capacity of 87.06 million gallons per day and currently discharges 37.85 million gallons per day. As a secondary treatment facility, it meets the minimum requirements of the US Clean Water Act for removing organic matter and suspended solids. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permitting program, administered by the Missouri Department of Natural Resources. The treated effluent is discharged into a local waterway, likely a tributary of the Black River or the St. Francis River, which ultimately flows into the Mississippi River and then the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems and maintain water quality in the region.

The plant discharges into a local stream that is part of the Mississippi River basin. The receiving water body supports diverse aquatic life, including fish and macroinvertebrates. Downstream, the Black River and St. Francis River provide habitat for species such as smallmouth bass and freshwater mussels. The plant's secondary treatment helps reduce nutrient loading and protect these ecosystems.
