DENTON WWTP - Doniphan County, Kansas Wastewater Treatment Plant

DENTON WWTP is a municipal wastewater treatment facility located in Doniphan County, Kansas, serving a small population of 186 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring basic removal of organic matter and suspended solids before discharge. The plant has a designed capacity of 45.42 units and a discharge volume of 45.43 units, indicating near-full utilization. As a U.S. 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 a local waterway that drains into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. This connection highlights the plant's role in maintaining downstream water quality in a region dominated by agricultural land use.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and empties into the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for birds and fish. The surrounding area is primarily agricultural, so the plant's nutrient removal helps mitigate downstream eutrophication risks in the Gulf of Mexico hypoxic zone.
