Mount Moriah Outfall Wastewater Treatment Plant, Newfoundland and Labrador

Mount Moriah Outfall is a municipal wastewater treatment facility located in Mount Moriah, Newfoundland and Labrador, Canada. The plant serves a small population of 1,559 residents and operates with secondary treatment, which is appropriate for its scale and coastal location. As a Canadian facility, it operates under federal and provincial regulations, including the Fisheries Act and the Wastewater Systems Effluent Regulations, which set national standards for effluent quality. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local marine environment, as the plant is within 10 km of the coast. The receiving waters ultimately flow into the Gulf of St. Lawrence, a vital marine ecosystem that supports diverse aquatic life, including fish stocks and marine mammals. The plant's coastal discharge requires careful management to protect water quality and marine habitats.

The plant discharges into the Gulf of St. Lawrence, a major marine basin that supports fisheries, marine mammals, and migratory birds. The coastal environment is ecologically sensitive, and secondary treatment helps reduce nutrient and pollutant loads to protect water quality and marine life.
