Outfall A Wastewater Treatment Plant, Prince Rupert, British Columbia

Outfall A is a municipal wastewater treatment plant located in Prince Rupert, British Columbia, on the north coast of Canada. The facility serves a small population of 352 residents and operates with secondary treatment, meeting standard Canadian wastewater regulations for coastal communities. The plant provides secondary treatment, which involves biological processes to reduce organic matter and suspended solids. As a small facility in a remote coastal area, it operates under British Columbia's Municipal Wastewater Regulation, which requires secondary treatment for discharges into sensitive environments. The plant's discharge volume is 267 cubic meters per day. The treated effluent is released into the coastal waters of the Pacific Ocean near the mouth of the Skeena River, a major salmon-bearing river system. This area supports diverse marine life, including fish, seabirds, and marine mammals. The plant's location within 10 km of the coast means its discharge directly influences the nearshore marine ecosystem.

Outfall A discharges into the coastal waters of the Pacific Ocean near Prince Rupert, within the Skeena River estuary. The Skeena River is one of Canada's most important salmon rivers, supporting runs of Chinook, sockeye, and coho salmon. The estuary provides critical habitat for juvenile fish and migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads to this ecologically sensitive marine environment.
