SAWYER WWTP - Sawyer, Kansas Wastewater Treatment Plant

SAWYER WWTP is a municipal wastewater treatment facility located in Sawyer, Kansas, United States. It serves a small population of 124 residents, typical of rural communities in the Great Plains region. The plant is situated along State Highway 42 in Pratt County. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity of 45.42 units closely matches its current discharge volume of 45.43 units, indicating full utilization. The treated effluent is discharged into local waterways that ultimately drain into the Arkansas River basin, a major tributary of the Mississippi River system. This discharge supports downstream aquatic ecosystems and agricultural water use in the region. The plant's operation is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Kansas Department of Health and Environment.

The plant discharges into local streams that flow into the Arkansas River, which traverses the Great Plains and eventually joins the Mississippi River. This watershed supports diverse aquatic life, including fish species such as channel catfish and plains killifish. The region's semi-arid climate means that maintaining water quality in these streams is critical for both ecological health and downstream agricultural irrigation.
