VANDUSER WWTP - Scott County, Missouri Wastewater Treatment Plant

VANDUSER WWTP is a municipal wastewater treatment facility located in Scott County, Missouri, United States. The plant serves a small population of 267 residents and operates as part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 132.49 million gallons and an annual discharge volume of 102.21 million gallons, the facility operates within its capacity. As a small-scale plant, it is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Mississippi River watershed. The Mississippi River system supports diverse aquatic life and provides drinking water for millions downstream. The plant's location in southeastern Missouri places it within the Mississippi Alluvial Plain, an ecologically significant region.

The plant discharges into tributaries of the Mississippi River, which flows into the Gulf of Mexico. The Mississippi River basin is a major ecological corridor supporting fish, migratory birds, and aquatic habitats. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
