STE GENEVIEVE WWTP - Ste. Genevieve County, Missouri Wastewater Treatment

STE GENEVIEVE WWTP is a municipal wastewater treatment facility located in Ste. Genevieve County, Missouri, United States. It serves a population of approximately 4,410 residents, placing it in the small community category under US regulatory frameworks. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources. For small communities, secondary treatment is typically required to meet effluent limits for biochemical oxygen demand and total suspended solids. The plant discharges treated wastewater into local waterways that ultimately drain into the Mississippi River basin. The Mississippi River system supports diverse aquatic life and provides drinking water for millions downstream. Proper treatment helps protect water quality in this major river system.

The plant's treated effluent flows into tributaries of the Mississippi River, one of the largest river systems in North America. The Mississippi River basin supports a wide range of aquatic species and provides critical habitat for migratory birds. Downstream, the river empties into the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. Effective wastewater treatment helps reduce nutrient loads and protect downstream ecosystems.
