Meriden WWTP - Jefferson County, Kansas Wastewater Treatment Plant

Meriden WWTP is a municipal wastewater treatment facility located in Jefferson County, Kansas, serving a small population of 782 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring effective removal of organic matter and suspended solids. The plant has a designed capacity of 405.04 million gallons per year and currently discharges 317.98 million gallons per year, indicating operational capacity within design limits. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Kansas Department of Health and Environment, which set effluent limits to protect water quality. The treated effluent is discharged into local waterways within the Kansas River basin, which ultimately drains to the Missouri River and then the Mississippi River. This watershed supports diverse aquatic life and provides water for agricultural and municipal uses downstream. The plant's secondary treatment helps reduce nutrient loading and protect the ecological health of the receiving waters.

The plant discharges into the Kansas River basin, which flows into the Missouri River and then the Mississippi River, eventually reaching the Gulf of Mexico. This watershed is ecologically significant, supporting diverse fish and wildlife habitats. The secondary treatment process reduces organic pollutants and helps mitigate downstream eutrophication risks in the Mississippi River Delta.
