North River Lagoon Wastewater Treatment Plant, Cornwall, Prince Edward Island

North River Lagoon is a municipal wastewater treatment facility located on Capital Drive in Cornwall, Prince Edward Island, Canada. The plant serves a population of approximately 2,045 residents and operates with secondary treatment, meeting the standard requirements for communities of this size in the province. As a secondary treatment facility, North River Lagoon provides biological treatment to reduce organic matter and suspended solids before discharge. The plant processes an average daily flow of 918.00 cubic meters. Canadian wastewater facilities are regulated under provincial and federal guidelines, including the Canada Water Act and the Prince Edward Island Environmental Protection Act, which set effluent quality standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Northumberland Strait, part of the Gulf of St. Lawrence. This coastal environment supports diverse marine life, including fish, shellfish, and migratory birds. The plant's proximity to the coast underscores the importance of effective treatment to protect sensitive estuarine and marine ecosystems.

The treated effluent from North River Lagoon enters the local drainage network that flows into the Northumberland Strait, a key arm of the Gulf of St. Lawrence. This coastal region supports important fisheries, including lobster and groundfish, and provides habitat for migratory waterfowl. The plant's location within 10 km of the coast means that its discharge can directly influence nearshore water quality and marine life, making secondary treatment essential for minimizing nutrient and pathogen inputs.
