Station P3 Degrilleur Wastewater Treatment Plant, Saint-Fulgence, Quebec

Station P3 Degrilleur is a municipal wastewater treatment plant located on Rue du Saguenay in Saint-Fulgence, Quebec, Canada. The plant serves a small community of 961 residents and operates under secondary treatment, which provides biological treatment to reduce organic matter and suspended solids. As a secondary treatment facility serving fewer than 2,000 people, the plant aligns with Canadian federal and provincial wastewater regulations, which require secondary treatment for discharges into sensitive environments. The plant's discharge volume is 431.40 cubic meters per day, reflecting its small scale. The treated effluent from Station P3 Degrilleur is discharged into the Saguenay River watershed, which flows into the St. Lawrence River and ultimately the Atlantic Ocean. The Saguenay Fjord is an ecologically sensitive area supporting diverse aquatic life, including beluga whales and migratory fish species.

The plant discharges into the Saguenay River, a major tributary of the St. Lawrence River. The Saguenay Fjord is a deep, cold-water estuary that supports a unique ecosystem, including beluga whales, seals, and various fish species. The St. Lawrence River then flows into the Gulf of St. Lawrence and the Atlantic Ocean, making the region an important migratory corridor for marine life.
