KEYTESVILLE WWTP - Keytesville, Missouri Wastewater Treatment Plant

KEYTESVILLE WWTP is a municipal wastewater treatment facility located in Keytesville, Chariton County, Missouri. The plant serves a small population of 533 residents, reflecting the rural character of the area. It operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment as a minimum standard for municipal plants. The plant provides secondary treatment, a biological process that significantly reduces organic matter and suspended solids. Its designed capacity is 234.69 megaliters per year, and it currently discharges 189.27 megaliters annually. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent is discharged into local streams that drain into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting the Chariton River basin from nutrient pollution and pathogens, supporting aquatic life and downstream water quality.

The plant discharges into tributaries of the Chariton River, which flows into the Missouri River and then the Mississippi River, eventually reaching the Gulf of Mexico. The watershed supports diverse aquatic habitats and is part of the larger Mississippi River basin, which is ecologically significant for migratory fish and waterfowl. Nutrient management is critical to prevent hypoxia in the Gulf.
