Port Darlington WPCP - Clarington, Ontario Wastewater Treatment Plant

Port Darlington WPCP is a municipal wastewater treatment plant serving the community of Clarington in the Durham Region of Ontario, Canada. The plant serves a population of approximately 27,321 and is situated near the northern shore of Lake Ontario, part of the Greater Toronto Area's wastewater infrastructure. As a Canadian facility, Port Darlington WPCP operates under provincial regulations administered by the Ontario Ministry of the Environment, Conservation and Parks. Plants of this scale typically employ secondary or tertiary treatment processes to meet effluent quality standards. The designed capacity is reported as 1.00 (likely in million litres per day or similar units), indicating a moderate-sized facility. The plant's treated effluent is discharged into the Lake Ontario watershed, which is part of the St. Lawrence River system and ultimately the Atlantic Ocean. Lake Ontario supports diverse aquatic life and serves as a drinking water source for millions. The plant's proximity to the lake underscores the importance of effective treatment to protect water quality and ecosystem health.

Port Darlington WPCP discharges into the Lake Ontario basin, which drains via the St. Lawrence River to the Atlantic Ocean. Lake Ontario is a large freshwater lake that supports diverse fish populations, including lake trout and salmon, and provides habitat for migratory birds. The plant's location within 50 km of the coast means its effluent can influence nearshore water quality, making nutrient and contaminant control critical for preventing algal blooms and protecting aquatic life.
