6 Marine Drive Wastewater Treatment Plant, St. Anthony, Newfoundland and Labrador

6 Marine Drive is a wastewater treatment plant located on McChada Drive in St. Anthony, a town on the Great Northern Peninsula of Newfoundland and Labrador, Canada. The plant serves a small population of 236 residents, reflecting the rural and coastal character of the community. The plant provides secondary treatment, which is a standard biological process that significantly reduces organic matter and suspended solids. Under Canadian federal and provincial regulations, secondary treatment is the minimum required for municipal wastewater, and this plant meets that standard. The plant discharges 106.00 cubic meters of treated wastewater daily. The treated effluent is released into the local marine environment, as the plant is within 10 km of the coast. St. Anthony sits on the shores of St. Anthony Bight, part of the Labrador Sea, which ultimately connects to the North Atlantic Ocean. The area supports diverse marine life, including fish stocks and seabird populations, making proper treatment essential for ecosystem health.

The plant discharges into the coastal waters of St. Anthony Bight, which flows into the Labrador Sea and then the North Atlantic Ocean. This marine environment supports important fisheries, including cod and crab, and provides habitat for seabirds and marine mammals. Secondary treatment helps reduce nutrient loading and organic pollution, protecting the sensitive coastal ecosystem from eutrophication and maintaining water quality for local communities and wildlife.
