McClure WWTP and Sewer System - Henry County, Ohio Wastewater Treatment

McClure WWTP and Sewer System is a municipal wastewater treatment facility located in Damascus Township, Henry County, Ohio, United States. The plant serves a small population of 761 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 454.25 units and an average daily discharge of 378.54 units, the facility operates below its maximum capacity, indicating adequate headroom for current demand. As a small-scale plant, it is subject to EPA NPDES permitting through the Ohio Environmental Protection Agency. The treated effluent is discharged into a local waterway within the Maumee River basin, which flows into Lake Erie. This watershed is part of the Great Lakes system, supporting diverse aquatic life and recreational activities. The plant's operations contribute to protecting downstream water quality in this ecologically sensitive region.

The plant discharges into a tributary of the Maumee River, which flows into the western basin of Lake Erie. Lake Erie is the shallowest of the Great Lakes and supports a productive fishery, but it has faced challenges from nutrient pollution, particularly phosphorus. The plant's secondary treatment helps reduce organic loading, though nutrient removal may be limited. The watershed is primarily agricultural, with runoff contributing to algal blooms in Lake Erie.
