Fall River WWTP - Secondary Treatment Plant in Fall River, Kansas

Fall River WWTP is a municipal wastewater treatment facility located in Fall River, Kansas, serving a small population of 146 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring that organic matter and suspended solids are reduced before discharge. The plant has a designed capacity of 113.56 volume units and currently treats 56.78 volume units, indicating it operates well below its capacity. As a US facility, it falls under the Clean Water Act and is subject to 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 that ultimately drains into the Verdigris River basin, part of the Arkansas River watershed. This region supports diverse aquatic life and is important for downstream water quality in the Mississippi River system.

The plant discharges into a tributary of the Verdigris River, which flows into the Arkansas River and eventually the Mississippi River. The local watershed is primarily rural and agricultural, so the plant's secondary treatment helps protect downstream aquatic habitats from nutrient pollution and organic loading. Maintaining low effluent concentrations is critical for the health of fish populations and recreational uses in the region.
