Convoy WWTP and Sewer System - Advanced Wastewater Treatment in Convoy, Ohio

Convoy WWTP and Sewer System is a municipal wastewater treatment facility located in Convoy, Van Wert County, Ohio. The plant serves a small population of 1,110 residents, providing advanced treatment to protect local water quality. As a facility in the United States, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. The plant utilizes advanced treatment processes, which go beyond secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 757.08 thousand cubic meters per year and an actual discharge volume of 643.52 thousand cubic meters, the facility operates at approximately 85% capacity, indicating efficient use of its infrastructure. The treatment level meets or exceeds federal and state standards for wastewater discharge. The treated effluent is discharged into a local waterway that ultimately drains into the Maumee River basin and then into Lake Erie. This watershed is part of the Great Lakes system, which supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps reduce nutrient loading, particularly phosphorus and nitrogen, which are critical for controlling harmful algal blooms in Lake Erie.

The plant discharges into a tributary of the Maumee River, which flows into the western basin of Lake Erie. This region is ecologically sensitive due to recurring harmful algal blooms driven by nutrient pollution. The advanced treatment at Convoy WWTP helps mitigate nutrient loading, protecting downstream aquatic habitats and the Lake Erie ecosystem, which supports fisheries and recreation.
