Secondary treatment is the minimum standard for municipal plants, ensuring removal of organic matter and suspended solids. The treated effluent is discharged into local surface waters that drain into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream aquatic habitats and maintaining water quality in the region's agricultural landscape.

The plant discharges into tributaries of the Missouri River, which flows south to join the Mississippi River and empty into the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a major migratory corridor for birds. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
