Windsor Lagoons Wastewater Treatment Plant, Windsor, Nova Scotia

Windsor Lagoons is a municipal wastewater treatment facility located on Lagoon Drive in Windsor, Nova Scotia, Canada. The plant serves a population of roughly 6,469 residents within the Region of Windsor and West Hants Municipality. As a lagoon-based system, it provides natural treatment through settling and biological processes, typical for smaller communities in Atlantic Canada. The plant operates under Canada's federal wastewater regulations, specifically the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act. These regulations set national effluent quality standards for carbonaceous biochemical oxygen demand, suspended solids, and residual chlorine. For a facility of this scale, lagoon systems are a common and cost-effective treatment approach that can achieve the required effluent quality when properly maintained. The treated effluent from Windsor Lagoons is discharged into the Avon River, a tidal river that flows into the Minas Basin, part of the Bay of Fundy. The Bay of Fundy is known for its extreme tidal ranges and rich marine ecosystems, including critical habitats for migratory birds and fish species. The plant's discharge contributes to the overall water quality in this dynamic estuarine environment.

Windsor Lagoons discharges into the Avon River, which flows into the Minas Basin, a major inlet of the Bay of Fundy. The Bay of Fundy is renowned for its high tidal range and supports diverse marine life, including important fish stocks and migratory shorebirds. The Minas Basin is an ecologically sensitive area that provides nursery habitat for fish and feeding grounds for seabirds. Protecting water quality in this watershed is essential for maintaining the health of downstream ecosystems.
