The plant serves a small population of around 1,068 residents, providing essential sanitation services to this rural community. As part of the municipal infrastructure, it ensures that wastewater is treated to high standards before being released into the environment. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,249.18 thousand gallons per day and an average discharge volume of 529.96 thousand gallons per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set strict limits on effluent quality to protect receiving waters. The treated effluent from Morrisonville STP is discharged into local streams that are part of the Mississippi River basin. These waterways eventually flow into the Mississippi River and then to the Gulf of Mexico. The advanced treatment helps reduce nutrient loading, which is critical for mitigating the hypoxic zone in the Gulf. The plant plays a vital role in maintaining water quality in the region's aquatic ecosystems.

Morrisonville STP discharges into local tributaries of the Mississippi River basin, which ultimately drains into the Gulf of Mexico. The advanced treatment process reduces nutrient pollution, helping to protect downstream aquatic life and mitigate the seasonal hypoxic zone in the Gulf.
