The plant is situated in Cass County and provides secondary treatment, which is the standard level for small communities under the US Clean Water Act. The plant has a designed capacity of 75.71 thousand gallons per day and currently discharges a similar volume, indicating full utilization.

The plant's operation helps protect the local watershed from untreated sewage contamination.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic habitats and is part of the larger Mississippi River drainage basin, an ecologically significant corridor for migratory fish and waterfowl.
