It’s being described as one of the most challenging projects ever built in Metro Vancouver and it’s finally complete after six years.
The $240-million Port Mann Water Supply Tunnel is the first in a series of major water transmission system upgrades across the region.
Metro Vancouver’s Frank Huber says it more than doubles the capacity of the old water main.
“We know we will need more water in the future and obviously we want to make sure that things are built in time to meet that demand.”
He says the project is not related to the quality of the water but just focuses on building resiliency while getting ready for the future.
The new water tunnel located more than 30 meters under the Fraser River bed and just west of the new Port Mann Bridge, will also be better able to withstand an earthquake.
