The plant has a designed capacity of 283.91 megaliters per year and currently treats an average discharge volume of 189.27 megaliters per year. Under the U.S. Clean Water Act, facilities of this scale are typically regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, which set effluent limits to protect water quality. The treated effluent from Montrose WWTP is discharged into a local waterway that eventually drains into the Osage River basin, part of the larger Missouri River watershed. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems and support the overall health of the Mississippi River basin.

The plant discharges into a tributary of the Osage River, which flows into the Missouri River and ultimately the Mississippi River and Gulf of Mexico. The receiving waters support diverse aquatic life, including fish and macroinvertebrates, and are part of a larger watershed that provides habitat for migratory birds and other wildlife. The secondary treatment process helps reduce nutrient loading, which is important for preventing eutrophication in downstream water bodies.
