Lagune Wastewater Treatment Plant, Paroisse de Beresford, New Brunswick

Lagune is a secondary wastewater treatment plant located in Paroisse de Beresford, within the Ville de Belle-Baie area of New Brunswick, Canada. The facility serves a small population of 423 residents, reflecting its role in a rural coastal community. The plant is situated near Pointe-Verte, close to the Chaleur Bay coastline. As a secondary treatment facility, Lagune meets the standard requirements for municipal wastewater treatment in Canada, where provincial regulations typically mandate secondary treatment for inland and coastal discharges. The plant operates under the oversight of New Brunswick's Department of Environment and Local Government, which issues permits under the Clean Environment Act. For a plant of this small scale, secondary treatment provides effective removal of organic matter and suspended solids. The treated effluent from Lagune is discharged into the local watershed, which drains into Chaleur Bay, an arm of the Gulf of St. Lawrence. This coastal environment supports diverse marine life, including fish, crustaceans, and migratory birds. The plant's proximity to the coast underscores the importance of maintaining treatment standards to protect the bay's water quality and ecological health.

Lagune discharges into the coastal waters of Chaleur Bay, which connects to the Gulf of St. Lawrence and ultimately the Atlantic Ocean. The bay is an ecologically sensitive area that supports a variety of marine species, including Atlantic salmon and lobster, and serves as a migratory corridor for seabirds. The plant's secondary treatment helps mitigate nutrient and pathogen loading, preserving the bay's water quality for both aquatic life and recreational use.
