Rocky River WWTP and Sewer System - Ohio Wastewater Treatment

The Rocky River WWTP and Sewer System is a municipal wastewater treatment facility located in Rocky River, Ohio, a suburb west of Cleveland. Serving a population of approximately 80,919, the plant is a key component of the region's wastewater infrastructure, managing sewage from residential and commercial sources in the Cuyahoga County area. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. For a plant serving this population size, secondary treatment is the minimum standard, with potential for additional nutrient removal to protect Lake Erie from algal blooms. The plant's treated effluent is discharged into Lake Erie, the shallowest and most biologically productive of the Great Lakes. Lake Erie supports a diverse aquatic ecosystem and provides drinking water for millions. The plant's location within 50 km of the coast underscores its role in protecting this sensitive freshwater resource from nutrient pollution and pathogens.

The plant discharges into Lake Erie, part of the Great Lakes system that drains via the Niagara River and St. Lawrence River to the Atlantic Ocean. Lake Erie faces challenges from nutrient loading, particularly phosphorus, which fuels harmful algal blooms. The plant's operations are critical to maintaining water quality in the lake's central basin, which supports fisheries and recreation.
