Centerville STP - Turner County, South Dakota Wastewater Treatment Plant

Centerville STP is a municipal wastewater treatment facility located in Turner County, South Dakota, serving a small population of 887 residents. The plant is situated in a rural agricultural region of the state, providing essential sanitation services to the community of Centerville and surrounding areas. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 340.69 volume units and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it falls under the regulatory oversight of the South Dakota Department of Environment and Natural Resources, which issues National Pollutant Discharge Elimination System (NPDES) permits for such plants. The treated effluent from Centerville STP is discharged into local streams that drain into the Vermillion River basin, which ultimately flows into the Missouri River. The Missouri River is a major tributary of the Mississippi River system, supporting diverse aquatic life and providing water for irrigation, recreation, and drinking water downstream. The plant's operations help protect water quality in this important regional watershed.
