Innovation
Once the tunnel was completed, the 600mm ID CPP feedermain was installed using a Ward and Burke engineered technique known as “pipe flotation” in conjunction with shaft-based pipe installation frame. A specifically designed cellular grouting campaign, was then employed to grout the tunnel/ watermain annulus.
The designed and constructed tunnel alignment for the Elgin Mills PD7 watermain, resulted in the longest, curved microtunnel ever constructed in North America/Canada, and is a testament to the Engineering and Operational Skills of Ward & Burke.
