Vancouver nears completion of $208 million water tunnel
Metro Vancouver is making progress on its long-term water security initiatives, with excavation for the Annacis Water Supply Tunnel nearing completion. According to Engineering News-Record, the 1.43-mi (2.3-km) steel main, which connects New Westminster and Surrey, is part of a $208.1 million ($288 million CAD) project awarded to Traylor Aecon General Partnership, with full completion expected by 2027.
Engineering firm COWI has also announced that its design work for the tunnel is entering the final phase. The Annacis tunnel is one of five under-river tunnels being constructed to enhance water supply reliability and replace aging infrastructure, representing a significant portion of a more than $1.4 billion investment ($2 billion CAD).
Future projects include allocations of CA$468.6 million for the Second Narrows Water Supply Tunnel and CA$495 million for the Stanley Park tunnel in the 2025-2029 financial plan. Additionally, the Coquitlam Lake Water Supply Project is progressing, which aims to bolster the region's major drinking water source, Engineering News-Record reported.
Metro Vancouver is prioritizing resilience against seismic disruptions through a comprehensive impact mitigation framework, developed with extensive stakeholder input. As the Annacis tunnel moves closer to becoming operational, officials emphasize that the investment aims to provide crucial support to the water supply system with minimal public notice unless necessary.
