South English WWTP: Wastewater Treatment in South English, Iowa

South English WWTP is a municipal wastewater treatment facility located in South English, Keokuk County, Iowa. The plant serves a small population of 210 residents, reflecting the rural character of the community. It is situated on Miller Street and provides essential sanitation services to the area. The plant employs secondary treatment, which is the standard biological treatment process required by the US Clean Water Act for municipal wastewater. With a designed capacity of 75.71 million gallons per day, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Iowa Department of Natural Resources. This regulatory framework ensures that effluent meets water quality standards to protect public health and the environment. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's operations help maintain water quality in the region's streams and rivers, supporting aquatic life and downstream ecosystems. As an inland facility, it plays a key role in protecting the local watershed from nutrient pollution and pathogens.

The plant discharges into receiving waters that are part of the Mississippi River watershed, which drains into the Gulf of Mexico. The region's streams support diverse aquatic life and are important for local agriculture and recreation. Proper treatment helps reduce nutrient loading that can contribute to hypoxia in the Gulf.
