Description
Description | The project involved replacing the original 1970s-era outfall pipe of the Annacis Island Wastewater Treatment Plant with a new tunnel system to increase capacity, enhance durability, and improve seismic resilience. The new system includes two 4.2-metre-diameter tunnels and a 2.5-meter-diameter diffuser manifold pipe system in the Fraser River to optimally disperse treated wastewater and minimize environmental impact. The project addresses future sea level rise and improves the plant's resilience to seismic events and environmental changes. |
