Mansfield WWTP is a municipal wastewater treatment plant located in Mansfield, Wright County, Missouri. The facility serves a population of approximately 1,296 residents, providing advanced treatment to protect public health and the environment. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,173.47 million gallons per day and an average discharge volume of 492.10 million gallons per day, the facility operates well within its capacity. As a US plant, it is regulated under the Clean Water Act and must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources. The treated effluent is discharged into local streams that are part of the Gasconade River watershed, which ultimately flows into the Missouri River and then the Mississippi River. This downstream chain supports diverse aquatic life and provides drinking water for communities. The advanced treatment helps minimize nutrient loading and protects water quality in these sensitive ecosystems.

The plant discharges into tributaries of the Gasconade River, which flows into the Missouri River and then the Mississippi River. This watershed supports a variety of fish and wildlife, including species that rely on clean water for spawning and habitat. The advanced treatment reduces nutrient pollution, helping to prevent algal blooms and maintain oxygen levels in downstream waters.
