The plant treats municipal wastewater from the local community, discharging into the regional watershed. The facility provides secondary treatment, which is the standard required by the US Clean Water Act for municipal plants of this scale. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 136.27 megaliters, and it currently processes 136.28 megaliters annually, indicating full utilization. The treated effluent is discharged into local waterways that drain into the Missouri River basin, ultimately reaching the Mississippi River and the Gulf of Mexico.

The plant discharges into the Missouri River watershed, which flows through the Great Plains and eventually joins the Mississippi River. This region supports diverse aquatic life, including native fish species and migratory birds. The semi-arid climate means water resources are critical for both ecological health and human use, making effective wastewater treatment essential for maintaining stream flows and water quality.
