Lagune Village de Neguac Wastewater Treatment Plant, Paroisse d'Alnwick, New Brunswick

Lagune Village de Neguac is a municipal wastewater treatment facility located in Neguac, within the Paroisse d'Alnwick, Northumberland County, New Brunswick, Canada. The plant serves a small community of approximately 1,114 residents and operates under the regulatory framework of the Canadian Environmental Protection Act and provincial guidelines for wastewater management in New Brunswick. The plant provides secondary treatment, which is the standard level required for communities of this size in Canada. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring effluent quality meets federal and provincial standards before discharge. The plant's discharge volume is recorded at 500 cubic meters per day, reflecting its scale. The treated wastewater is discharged into the local environment, which drains into the Gulf of St. Lawrence via nearby coastal waters. This area supports diverse marine life and is part of the larger Gulf of St. Lawrence ecosystem, which is ecologically sensitive due to its role in fisheries and migratory bird habitats. The plant's coastal location requires careful management to protect downstream water quality.

The plant discharges into the Gulf of St. Lawrence, a major estuary and marine ecosystem that supports commercial fisheries, including lobster and crab, and serves as a critical habitat for seabirds and marine mammals. The watershed is characterized by boreal forest and coastal wetlands, which filter runoff and provide nursery grounds for fish. The plant's secondary treatment helps mitigate nutrient loading and pathogen risks to this sensitive coastal environment.
