It serves a population of approximately 93,398 residents in the Liverpool Township area of Medina County. The plant is part of the regional wastewater infrastructure managed by the local sewer district. As a facility serving a medium-to-large agglomeration, it operates under the U. S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. Plants of this scale typically employ secondary or advanced treatment to meet permit limits. The designed capacity is reported as 1.00, though the unit is unspecified. The plant's treated effluent ultimately drains into the Lake Erie watershed via local tributaries. Lake Erie is a vital freshwater resource supporting drinking water, recreation, and diverse aquatic life. The plant's discharge must comply with Ohio EPA standards to protect downstream water quality and the lake's ecological health.

The plant discharges into the Lake Erie basin, part of the Great Lakes system, which provides drinking water to millions and supports a rich fishery. The watershed includes numerous rivers and streams that flow into the lake, requiring careful nutrient management to prevent algal blooms. The plant's operations are critical to maintaining water quality in this sensitive freshwater ecosystem.
