The Kapoor Tunnel is a straight 8.8 km (5.5 mi) subterranean route which is the main transport of water from the Sooke Lake to the Westshore, City of Victoria, Esquimalt, and the Saanich Peninsula. When it was determined that the Sooke Flowline would no longer meet the region's needs, the decision was made to excavate the tunnel. Prior to construction of the flowline, Arthur Adams, the consultant for the flowline construction, had proposed the Kapoor Tunnel be built.
