Holmes Co Mount Hope WWTP and Sewers - Advanced Treatment in Mount Hope, Ohio

Holmes Co Mount Hope WWTP and Sewers is a municipal wastewater treatment facility located in Mount Hope, Holmes County, Ohio. The plant serves a small population of 220 residents, providing advanced treatment to protect local water quality. As a facility in the United States, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 83.28 thousand cubic meters, with an actual discharge volume of 75.71 thousand cubic meters annually. For small agglomerations like this, the US EPA typically requires secondary treatment as a minimum, but advanced treatment indicates a higher level of environmental protection. The treated effluent is discharged into a local waterway that ultimately drains into the Ohio River basin. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the overall health of the watershed. Its inland location reduces direct marine impact, but careful management is still essential for local streams and rivers.

The plant discharges into a tributary of the Ohio River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in downstream water bodies.
