Shelby Co Arrowhead Hills WWTP - Advanced Wastewater Treatment in Shelby County, Ohio

Shelby Co Arrowhead Hills WWTP is a municipal wastewater treatment plant located in Shelby County, Ohio, United States. The facility serves a small population of 450 residents, reflecting its role in a rural or suburban community. The plant is situated inland, away from coastal areas, and operates under the regulatory framework of the US Clean Water Act. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 264.98 units and an average discharge volume of 170.34 units, the facility operates below its maximum capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body, likely a tributary of the Great Miami River or the Ohio River basin. This discharge supports the health of downstream aquatic ecosystems and contributes to the overall water quality of the region. The advanced treatment level helps protect sensitive waters from nutrient pollution and other contaminants.

The plant discharges into a local stream within the Great Miami River watershed, which flows into the Ohio River and ultimately the Mississippi River. This inland basin supports diverse aquatic life and is used for recreation and drinking water. Advanced treatment helps minimize nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for communities along the river.
