Bloomsdale WPC Plant - Secondary Wastewater Treatment in Bloomsdale, Missouri

The Bloomsdale WPC Plant is a municipal wastewater treatment facility located near Interstate 55 in Bloomsdale, Ste. Genevieve County, Missouri. Serving a small population of 321, the plant provides secondary treatment, which is the minimum standard for municipal wastewater under the U.S. Clean Water Act. With a designed capacity of 264.98 megaliters per year and an annual discharge volume of 151.42 megaliters, the plant operates well within its capacity. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharge. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Missouri Department of Natural Resources. The treated effluent is discharged into a local waterway that ultimately drains into the Mississippi River basin. The Mississippi River system supports diverse aquatic life and provides drinking water for millions. The plant's discharge contributes to the overall water quality in the region, and its secondary treatment helps protect downstream ecosystems.

The plant discharges into a tributary of the Mississippi River, which flows south to the Gulf of Mexico. The Mississippi River basin is one of the largest watersheds in North America, supporting a wide range of aquatic species and providing critical habitat for migratory birds. The plant's secondary treatment reduces nutrient loads, helping to mitigate hypoxia in the Gulf of Mexico.
