Clarksburg WWTP and Sewer System - Advanced Treatment Plant in Ohio

Clarksburg WWTP and Sewer System is a municipal wastewater treatment facility located in Clarksburg, Ross County, Ohio, United States. The plant serves a small population of 540 residents, reflecting its role in a rural community. It is situated inland, far from coastal waters, 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 additional pollutants such as nutrients. It has a designed capacity of 454.25 megaliters per year and currently discharges 227.13 megaliters per year, indicating it operates below its full capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, which set limits on effluent quality to protect receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Ohio River basin. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Ohio River and its tributaries, which support diverse fish populations and are used for recreation and drinking water supply. The facility plays a key role in maintaining water quality in this inland watershed.

The plant discharges into local streams that flow into the Scioto River, a major tributary of the Ohio River. The Ohio River basin supports a variety of aquatic life, including freshwater mussels and game fish, and provides drinking water for millions. The advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream waters.
