Kingston WWTP - Caldwell County, Missouri Wastewater Treatment Plant

Kingston WWTP is a municipal wastewater treatment facility located in Caldwell County, Missouri, United States. The plant serves a small population of 348 residents, reflecting its role in a rural community. It is situated near Missouri State Highway 13, providing access for operations and maintenance. The plant employs secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 155.20 million gallons per year and an annual discharge volume of 109.78 million gallons, the facility operates below its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into a local waterway within the Missouri River basin, which ultimately flows into the Mississippi River and the Gulf of Mexico. The plant's operations contribute to protecting downstream aquatic ecosystems by reducing pollutant loads in the watershed.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The secondary treatment process helps reduce nutrient and organic pollution, mitigating the risk of eutrophication in downstream waters.
