Hamden WWTP and Sewer System - Advanced Wastewater Treatment in Hamden, Ohio

Hamden WWTP and Sewer System is a municipal wastewater treatment facility located at 78 Thacker Avenue in Hamden, Vinton County, Ohio. The plant serves a small population of 884 residents, reflecting the rural character of the area. It operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. The plant provides advanced treatment, which goes beyond the secondary treatment standard typically required for municipal facilities. Its designed capacity is 473.18 megaliters per year, and it treats an average annual volume of 378.54 megaliters, indicating operational headroom. The advanced treatment level suggests the plant may employ nutrient removal or other tertiary processes to meet stringent water quality standards. The treated effluent is discharged into a local receiving water body, likely a tributary of the Ohio River basin. The plant's location in southeastern Ohio places it within the Appalachian region, where watersheds support diverse aquatic life. The advanced treatment helps protect downstream water quality in the Ohio River system, which ultimately drains to the Mississippi River and the Gulf of Mexico.

The plant discharges into a local stream within the Ohio River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. The receiving waters support diverse aquatic species, including fish and macroinvertebrates sensitive to nutrient pollution. Advanced treatment at this facility helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and maintaining water quality for recreational and ecological uses.
