DCSD Steven A Rogers WWTF - Advanced Wastewater Treatment in O'Fallon, Missouri

DCSD Steven A Rogers WWTF is a wastewater treatment facility located in O'Fallon, Missouri, United States. The plant provides advanced treatment for a small population of 135 residents, ensuring high-quality effluent before discharge. It operates as part of the municipal wastewater infrastructure in Saint Charles County. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 49.21 volume units and a discharge volume of 49.21, the facility operates at full capacity. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, ensuring environmental standards are met. The treated effluent is discharged into a local receiving water body, which flows into the Missouri River and ultimately the Mississippi River. This contributes to the health of the Mississippi River Basin, a major ecological and economic resource. The plant's advanced treatment helps protect downstream aquatic life and water quality in this important watershed.

The plant discharges into a local stream that drains into the Missouri River, a major tributary of the Mississippi River. The Mississippi River Basin supports diverse aquatic ecosystems and provides drinking water for millions. The advanced treatment at this facility reduces nutrient loading, helping to mitigate hypoxia in the Gulf of Mexico, where the Mississippi River ends.
