Water Quality / Structural Improvement

Vancouver Street | Fort St. to McClure St.
City of Victoria - Victoria, BC Canada

November 2014

The 3M Scotchkote Pipe Renewal Liner 2400 product was the perfect application for the needs of the city of Victoria.In the fall of 2014, Canadian Induracoat Corporation was awarded a bid to line over 300 meters of Victoria's aging watermains. The project required minimal impact on traffic flows in the area, and priority concern was given to the wide range of mature, and fully established trees within the neighbourhood.

The area was also a heavy mixture of residential dwellings, historical structures, and commercial businesses. Every effort was made to ensure that Induracoat's personel & equipment were of minimal disruption to the area residents & businesses.

“The dozens of beautiful trees lining both sides of Vancouver Street in Victoria were planted long after the water main installation in 1908. Water main replacement would have likely been lethal to the trees given the water mains current proximity.

The use of the Scotchkote Liner 2400 provided the city with a trenchless, semi-structural rehabilitation solution without harm to the trees and significantly reduced impact on local traffic flows.”
