MT VERNON WWTP | Mount Vernon, Missouri Wastewater Treatment Plant

MT VERNON WWTP is a municipal wastewater treatment facility located in Mount Vernon, Lawrence County, Missouri. The plant serves a population of approximately 4,575 people, making it a small to medium-sized facility typical of rural communities in the Midwest United States. As a US-based plant, MT VERNON WWTP operates under the Clean Water Act and is regulated by the Missouri Department of Natural Resources through a National Pollutant Discharge Elimination System (NPDES) permit. For a facility of this scale, secondary treatment is the standard requirement, ensuring that organic matter and suspended solids are adequately removed before discharge. The treated effluent from MT VERNON WWTP is discharged into a local receiving water body, which ultimately drains into the Spring River and then the White River system, flowing toward the Mississippi River basin. This watershed supports diverse aquatic life and provides water resources for downstream communities and ecosystems in the Ozarks region.

The plant's discharge enters a local stream that flows into the Spring River, a tributary of the White River system. The White River eventually reaches the Mississippi River and the Gulf of Mexico. This watershed supports diverse aquatic species, including fish and macroinvertebrates, and is an important resource for recreation and agriculture in southwestern Missouri.
