Sidney WWTP and Sewer System - Municipal Wastewater Treatment in Sidney, Ohio

Sidney WWTP and Sewer System is a municipal wastewater treatment facility located in Sidney, Shelby County, Ohio. The plant serves a population of around 21,744 residents, classifying it as a medium-sized agglomeration under US regulatory standards. It is situated inland, approximately 50 kilometers from the nearest coast, and its operations are integral to the local infrastructure. As a US facility, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Ohio Environmental Protection Agency. For a plant serving this population size, secondary treatment is typically required, with potential additional nutrient removal depending on the receiving water body's sensitivity. The plant's design capacity and treatment processes are managed to meet permit limits that protect water quality. The treated effluent is discharged into a local water body, likely a tributary of the Great Miami River, which flows into the Ohio River and ultimately the Mississippi River Basin. This discharge supports the ecological health of the downstream aquatic environment, including fish habitats and recreational uses. The plant's performance is crucial for maintaining water quality in the region's watershed.

The plant discharges into a tributary of the Great Miami River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is used for recreation and drinking water supply downstream. The plant's nutrient removal helps prevent algal blooms and maintains oxygen levels in the river system.
