Stockton WWTP - Advanced Wastewater Treatment in Stockton, Kansas

Stockton WWTP is a municipal wastewater treatment facility located in Stockton, Kansas, United States. It serves a population of approximately 1,439 residents, making it a small-scale plant typical of rural communities in the Great Plains region. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 548.88 units and a discharge volume of 545.10 units, it operates near full capacity. As a US facility, it is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body, likely a stream or river within the Kansas River basin, which ultimately drains to the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens.

The plant discharges into a receiving water body within the Kansas River watershed, which flows into the Missouri River and then the Mississippi River, eventually reaching the Gulf of Mexico. This region is part of the Mississippi River Basin, which faces challenges from nutrient runoff contributing to the Gulf of Mexico hypoxic zone. Advanced treatment at Stockton WWTP helps reduce nutrient loads, supporting downstream water quality and aquatic life.
