The Columbus Grove WWTP and Sewer System is a municipal wastewater treatment facility located in Columbus Grove, Ohio, serving a population of about 2,200. The plant is situated in Pleasant Township, Putnam County, and is part of the region's essential water management infrastructure. As a small-scale treatment plant in the United States, it operates under the regulatory framework of the Clean Water Act, administered by the Ohio Environmental Protection Agency. Facilities of this size typically employ secondary treatment processes to meet National Pollutant Discharge Elimination System (NPDES) permit requirements, ensuring compliance with federal and state water quality standards. The plant's treated effluent is discharged into local waterways that drain into the Blanchard River, a tributary of the Auglaize River, which flows into the Maumee River and ultimately into Lake Erie. This watershed is part of the Great Lakes Basin, supporting diverse aquatic life and providing recreational and drinking water resources for downstream communities.
