The plant serves a small population of 652 residents, typical of rural communities in the Great Plains region. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants of this scale. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 264.98 million gallons per year, matching its current discharge volume. The treated effluent is discharged into local waterways that drain into the Wild Rice River watershed, which flows southward to the Red River of the North and eventually into Lake Winnipeg.

The plant discharges into the Wild Rice River watershed, which flows into the Red River of the North and ultimately reaches Lake Winnipeg. This downstream environment supports a variety of fish species and provides critical habitat for migratory waterfowl along the Central Flyway. The region's flat terrain and agricultural land use mean that nutrient management is important to prevent eutrophication in receiving waters.
