Shelby Co Fair Haven WWTP - Advanced Treatment Facility in Sidney, Ohio

Shelby Co Fair Haven WWTP is a wastewater treatment plant located in Sidney, Ohio, within Shelby County. The facility serves a small population of approximately 300 residents, reflecting its role in a rural or suburban setting. As part of the United States' wastewater infrastructure, the plant operates under the Clean Water Act, which mandates that publicly owned treatment works meet secondary treatment standards, though this plant provides advanced treatment beyond that baseline. The plant employs advanced treatment processes, indicating a higher level of pollutant removal compared to conventional secondary treatment. Its designed capacity is 49.21 units, with an actual discharge volume matching that figure, suggesting the plant operates at full capacity. Facilities of this scale in Ohio are typically regulated under the National Pollutant Discharge Elimination System (NPDES) program, administered by the Ohio Environmental Protection Agency. The treated effluent from the plant is discharged into a local water body, which ultimately drains into the Great Miami River watershed and then into the Ohio River. This downstream pathway connects to the Mississippi River system, eventually reaching the Gulf of Mexico. The advanced treatment helps protect the aquatic ecosystems in these waters, particularly in a region where agricultural runoff and urban impacts can affect water quality.

The plant's discharge enters a local tributary within the Great Miami River basin, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional water supply. The advanced treatment level helps reduce nutrient loading and other pollutants, mitigating potential impacts on downstream ecosystems, including sensitive habitats in the Ohio River corridor.
