B 4 Gallix Wastewater Treatment Plant, Gallix, Sept-Îles, Québec

B 4 Gallix is a municipal wastewater treatment facility located in the Gallix sector of Sept-Îles, Québec, Canada. The plant serves a small population of 188 residents and operates under secondary treatment standards, which is appropriate for its scale and the regulatory requirements of the province. The plant is situated within 10 km of the coast, indicating that treated wastewater is discharged into a marine environment. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge, meeting the standards set by Canadian federal and provincial regulations for coastal discharges. The receiving water body is the Gulf of St. Lawrence, a major estuary and marine ecosystem that supports diverse aquatic life, including fish, marine mammals, and seabirds. The plant's discharge contributes to the overall water quality management in the region, which is important for maintaining the ecological health of the coastal waters.

The plant discharges into the Gulf of St. Lawrence, a large marine estuary that receives freshwater from the St. Lawrence River and numerous smaller rivers along the Côte-Nord coast. This area supports a rich marine ecosystem, including commercial fisheries and migratory bird populations. The secondary treatment level helps reduce nutrient and pollutant loads, protecting the sensitive coastal environment from eutrophication and other impacts.
