Holmes Co October Hills WWTP and Sewers - Spellacy, Ohio Wastewater Treatment Plant

Holmes Co October Hills WWTP and Sewers is a wastewater treatment facility located in Spellacy, Holmes County, Ohio, United States. It serves a small population of 300 residents, reflecting its role in a rural community. The plant is situated inland, far from coastal areas, and operates under the regulatory framework of the US Clean Water Act. The facility provides advanced treatment, which goes beyond the secondary treatment standard typically required for small plants under the National Pollutant Discharge Elimination System (NPDES). With a designed capacity of 227.12 m³/day and a current discharge volume of 75.71 m³/day, the plant has ample capacity to accommodate future growth. Advanced treatment ensures high-quality effluent, reducing nutrient and pollutant loads. The treated wastewater is discharged into a local water body, likely a tributary of the Muskingum River or the Lake Erie basin, given the location in Ohio. The plant's advanced treatment helps protect downstream aquatic ecosystems, including streams and rivers that support diverse fish and macroinvertebrate communities. Its inland location minimizes direct marine impact.

The plant discharges into a local water body within the Muskingum River watershed, which ultimately drains to the Ohio River and then the Mississippi River. This inland system supports a variety of freshwater species, including game fish and mussels. The advanced treatment helps maintain water quality in these sensitive riverine habitats, reducing the risk of eutrophication and protecting biodiversity.
