Station d epuration Wastewater Treatment Plant, Percé, Québec

Station d epuration is a municipal wastewater treatment plant located along Route 132 in Percé, a coastal town in the Gaspésie-Îles-de-la-Madeleine region of Québec, Canada. The plant serves a small population of 387 residents and operates with secondary treatment, which is appropriate for its scale and the sensitive coastal environment. As a Canadian facility, the plant operates under provincial and federal regulations, including the Canadian Environmental Protection Act and Québec's Environment Quality Act. For small communities like Percé, secondary treatment is the standard to reduce organic matter and suspended solids before discharge. The treated effluent is released into the Gulf of St. Lawrence, a major marine ecosystem that supports diverse aquatic life, including fish, crustaceans, and marine mammals. The plant's proximity to the coast (within 10 km) underscores the importance of effective treatment to protect coastal water quality and the region's tourism and fishing industries.

The plant discharges into the Gulf of St. Lawrence, a large marine estuary that drains much of eastern Canada. The Gulf supports critical habitats for species such as Atlantic cod, herring, and the endangered North Atlantic right whale. The coastal waters near Percé are ecologically sensitive, with rocky shores and islands that host seabird colonies. Effective wastewater treatment is vital to prevent nutrient enrichment and pathogen contamination in this productive marine environment.
