Williams Co South Central SD Wastewater Treatment Plant, Oak Meadows, Ohio

Williams Co South Central SD is a municipal wastewater treatment facility located in Oak Meadows, Ohio, within Williams County. The plant serves a small community of 834 residents, reflecting its role in managing local domestic wastewater in a rural setting. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 480.75 cubic meters per day and an average daily discharge of 378.54 cubic meters, the facility operates below its capacity, indicating room for future growth. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, ensuring compliance with effluent limits. The treated effluent is discharged into local waterways that ultimately drain into the Maumee River basin, which flows into Lake Erie. This connection to the Great Lakes ecosystem underscores the plant's role in protecting water quality in a region sensitive to nutrient pollution, particularly phosphorus and nitrogen that can contribute to harmful algal blooms.

The plant discharges into tributaries of the Maumee River, which flows into the western basin of Lake Erie. This region is ecologically significant as a major freshwater resource and supports diverse aquatic life, including fish and migratory birds. The Maumee River watershed is heavily agricultural, and nutrient runoff from both point and non-point sources has been linked to eutrophication and harmful algal blooms in Lake Erie, making effective wastewater treatment critical for downstream water quality.
