Holmes Co Berlin Village WWTP and Sewers - Advanced Treatment Facility in Berlin, Ohio

Holmes Co Berlin Village WWTP and Sewers is a municipal wastewater treatment plant located in Berlin, Ohio, United States. The facility serves a population of approximately 1,500 residents and 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. As an advanced treatment plant, it provides a higher level of pollutant removal beyond secondary treatment, ensuring compliance with stringent water quality standards. The plant has a designed capacity of 1135.62 thousand cubic meters and currently discharges 503.46 thousand cubic meters of treated wastewater annually. The treatment process likely incorporates biological nutrient removal or chemical processes to meet advanced treatment requirements. The plant is subject to Ohio EPA oversight and must adhere to discharge limits for parameters such as biochemical oxygen demand, total suspended solids, and nutrients. The treated effluent is discharged into a local water body within the Muskingum River watershed, which ultimately drains to the Ohio River and then the Mississippi River system. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways, which are important for recreation and biodiversity.

The plant discharges into a tributary of the Muskingum River, which flows into the Ohio River and eventually the Mississippi River. The watershed supports diverse aquatic life, including fish species such as smallmouth bass and channel catfish. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream water bodies and maintaining water quality for recreational use.
