McArthur WWTP and Sewer System - Municipal Wastewater Treatment in McArthur, Ohio

The McArthur WWTP and Sewer System is a municipal wastewater treatment facility located at 329 Fairview Avenue in McArthur, Vinton County, Ohio. Serving a population of approximately 1,888, this plant is part of the small community's essential water infrastructure in southeastern Ohio. As a US facility serving fewer than 10,000 people, the plant is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting requirements under the Clean Water Act. Small municipal plants like this typically employ secondary treatment processes such as activated sludge or lagoon systems to meet discharge standards. The plant's treated effluent likely discharges to a local stream within the Ohio River basin, ultimately draining to the Mississippi River and Gulf of Mexico. The surrounding region features mixed forest and agricultural land use, with the plant playing a key role in protecting local water quality in Vinton County.

The plant serves McArthur in the Appalachian foothills of southeastern Ohio, within the Hocking River watershed. Treated effluent from the plant flows into local tributaries that drain to the Hocking River, a major tributary of the Ohio River. The Ohio River then joins the Mississippi River system, discharging into the Gulf of Mexico. This downstream chain supports diverse aquatic life and provides drinking water for millions downstream, making effective treatment critical for regional water quality.
