Basin G Wastewater Treatment Plant, Corner Brook, Newfoundland and Labrador

Basin G is a wastewater treatment plant located on Riverside Drive in Corner Brook, Newfoundland and Labrador, Canada. The facility serves a population of about 16,036 and is classified as a medium-sized agglomeration under Canadian wastewater management frameworks. As an operational plant, Basin G is subject to federal and provincial regulations, including the Canadian Environmental Protection Act and the Wastewater Systems Effluent Regulations (WSER), which set national standards for effluent quality. For communities of this scale, secondary treatment is typically required to reduce pollutants before discharge. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Humber River and then into the Bay of Islands, an inlet of the Gulf of St. Lawrence. This coastal environment supports diverse marine life and is important for local fisheries and recreation.

Basin G discharges into the Humber River, which flows into the Bay of Islands and then the Gulf of St. Lawrence. This coastal ecosystem supports a variety of fish species, including Atlantic salmon, and is a critical habitat for seabirds and marine mammals. The plant's location within 50 km of the coast means its effluent can influence nearshore water quality and the health of downstream estuarine environments.
