Overview
Shannon Road Aerated Lagoon serves the Town of Grand Bay-Westfield, New Brunswick, Canada, treating wastewater for approximately 4,112 residents. The plant is operational and located near the coast, discharging into the local watershed.
Shannon Road Aerated Lagoon is a municipal wastewater treatment facility located at 67 Shannon Road in Grand Bay-Westfield, New Brunswick, Canada. The plant serves a population of approximately 4,112 residents in this community within Kings County. As a Canadian facility, it operates under provincial and federal environmental regulations, including the Fisheries Act and the Wastewater Systems Effluent Regulations (WSER), which set national effluent quality standards for systems serving this population size. The plant uses an aerated lagoon treatment process, a common technology for small to medium communities in Canada. Under WSER, facilities of this scale are required to meet carbonaceous biochemical oxygen demand (CBOD) and total suspended solids (TSS) limits, with monitoring and reporting obligations to Environment and Climate Change Canada. The treated effluent is discharged into the Saint John River watershed, which flows into the Bay of Fundy. The Bay of Fundy is known for its extreme tidal ranges and supports diverse marine life, including migratory fish species. The plant's proximity to the coast (within 50 km) means its discharge can influence downstream estuarine and coastal ecosystems.
Environmental context
The plant discharges into the Saint John River basin, which drains into the Bay of Fundy, a globally significant estuary with the highest tides in the world. The Bay of Fundy supports critical habitats for fish, seabirds, and marine mammals, including the endangered North Atlantic right whale. The watershed is also important for Atlantic salmon and other diadromous species. Effluent from the plant must meet Canadian wastewater standards to protect these sensitive downstream environments.
