Lagoon Wastewater Treatment Plant, Paroisse de Balmoral, New Brunswick

The Lagoon wastewater treatment plant is located in Paroisse de Balmoral, a rural community within the Village de Bois-Joli in Restigouche County, New Brunswick, Canada. The facility serves a population of approximately 1,111 residents, providing essential wastewater treatment for this small agglomeration. The plant employs secondary treatment, which is the standard level required under Canadian federal and provincial regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges an average of 499 cubic meters of treated wastewater per day. The treated effluent is released into the local watershed, which ultimately drains into the Restigouche River and then into the Baie des Chaleurs, part of the Gulf of St. Lawrence. This coastal discharge location requires careful management to protect the sensitive marine environment and the region's important salmon fisheries.

The plant discharges into the Restigouche River watershed, which flows into the Baie des Chaleurs, a major estuary of the Gulf of St. Lawrence. This coastal area supports diverse aquatic life, including Atlantic salmon and other migratory fish species. The proximity to the coast (within 10 km) means treated effluent can quickly reach marine waters, necessitating effective treatment to minimize nutrient and pathogen impacts on the ecosystem.
