Serving a population of approximately 1,135, this plant provides essential sanitation services for the small community. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 934.99 thousand gallons per day and an average daily flow of 514.82 thousand gallons per day, it operates well within its capacity. As a US facility, it is regulated under the Clean Water Act, with NPDES permits issued by the Ohio Environmental Protection Agency to control discharges and protect water quality. The treated effluent is discharged into local streams that drain into the Maumee River watershed, ultimately flowing into Lake Erie. This makes the plant's performance critical for reducing nutrient loading and protecting the lake's ecosystem, which supports diverse aquatic life and recreational activities.

The plant discharges into tributaries of the Maumee River, which flows into the western basin of Lake Erie. This region is ecologically sensitive due to harmful algal blooms driven by nutrient pollution. The advanced treatment helps reduce phosphorus and nitrogen loads, supporting the health of Lake Erie's fisheries and drinking water supplies.
