Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 15.14 million gallons per day and discharges a similar volume, indicating it operates at full capacity. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets limits on pollutant discharges to protect water quality and aquatic life in the receiving waters.

The plant discharges into local streams that are part of the Mississippi River watershed. This region supports diverse aquatic habitats and is important for migratory birds and fish species. The secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in the Mississippi River and the Gulf of Mexico.
