ELGIN WWTP - Secondary Wastewater Treatment in Elgin, Oklahoma

ELGIN WWTP is a municipal wastewater treatment facility located in Elgin, Osage County, Oklahoma, United States. The plant serves a small population of 209 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment as a minimum standard for municipal wastewater plants. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 109.78 units and a current discharge volume of 79.49 units, the facility operates below its capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body, likely a stream or river within the Arkansas River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant's location inland and its small scale minimize its impact on sensitive coastal ecosystems, but local water quality is protected through state and federal regulations.

The plant discharges into a receiving water body within the Arkansas River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This inland location supports local aquatic life and downstream water quality. The small population served and secondary treatment level help maintain ecological balance in the surrounding streams and rivers.
