Located on Whiskey Island in the Ohio City neighborhood, it provides essential sanitation services to a population of around 122,500 residents. As part of the Northeast Ohio Regional Sewer District (NEORSD), the plant plays a key role in regional water quality management. The plant operates under the U. S. Clean Water Act, which requires secondary treatment for municipal wastewater. Facilities of this scale typically employ biological treatment processes to meet National Pollutant Discharge Elimination System (NPDES) permit limits. The designed capacity of 1.00 million gallons per day indicates the plant's infrastructure scale. The plant discharges treated effluent into Lake Erie, the fourth-largest of the Great Lakes and a vital source of drinking water and recreation. The Lake Erie watershed supports diverse aquatic life and is subject to nutrient pollution concerns, particularly phosphorus loading that contributes to harmful algal blooms. The plant's operations are critical to protecting this sensitive ecosystem.

Environmental context

The NEORSD Westerly WWTP discharges into Lake Erie, part of the Great Lakes system that ultimately drains via the St. Lawrence River to the Atlantic Ocean. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting important fisheries and migratory bird populations. The watershed faces challenges from agricultural runoff and urban stormwater, making effective wastewater treatment essential for controlling nutrient inputs and protecting water quality.
