ANDOVER WWTP | Andover, Kansas Wastewater Treatment Plant

ANDOVER WWTP is a municipal wastewater treatment facility located in Andover, Kansas, a city in Butler County. The plant serves a population of roughly 9,546 people, classifying it as a small to medium-sized agglomeration under U.S. regulatory frameworks. As a U.S. facility, the plant operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For plants of this scale, secondary treatment is typically mandated to reduce organic pollutants and suspended solids before discharge. The treated effluent is discharged into local waterways that drain into the Arkansas River basin, ultimately contributing to the Mississippi River system. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region.

The plant discharges into local streams that flow into the Arkansas River, a major tributary of the Mississippi River. This watershed supports diverse aquatic life and provides water for agricultural and municipal use downstream. The plant's operations help mitigate nutrient loading and protect the ecological health of the Arkansas River basin.
