Kingston WWT - Advanced Wastewater Treatment in Marshall County, Oklahoma

Kingston WWT is a municipal wastewater treatment facility located in Marshall County, Oklahoma, United States. The plant serves a small community of approximately 1,390 residents, providing advanced treatment to protect local water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 946.35 megaliters and an annual discharge volume of 757.08 megaliters, it operates under the U.S. Clean Water Act, which requires NPDES permits for all discharges to surface waters. The treated effluent is discharged into local waterways that eventually drain into the Red River basin. This region supports diverse aquatic life and is important for downstream ecosystems, including wetlands and reservoirs that provide habitat for fish and migratory birds.

The plant discharges into tributaries of the Red River, which flows south to the Mississippi River and ultimately the Gulf of Mexico. The local watershed supports diverse aquatic species and is part of a larger basin that provides critical habitat for migratory waterfowl and fish. Advanced treatment helps reduce nutrient loading, protecting downstream water quality in lakes and coastal zones.
