Horizontal Directional Drilling Installation of Segmented PVC Watermain Pipe in Richmond, Canada
The City of Richmond is part of the Greater Vancouver Regional District in British Columbia, Canada and is located on a flood plain with elevations ranging from approximately 0.6 metres to 2.5 metres above sea level. These physical attributes present numerous challenges and opportunities with underground utility design and construction. Design and construction of water mains in combination with soft soil, river delta ground conditions in particular lends itself to trenchless construction opportunities. The City established an Asbestos Cement water main replacement program in the 1990's and the Shellmont watermain replacement project was designed to be undertaken using the conventional "open trench" procedure. The contractor proposed the use of HDD and segmented Cobra Lock PVC C900 DR18 pipe as an alternative, "trenchless" method as an innovative opportunity and one that would reduce costs and provide many tangible benefits to residents adjacent to the work. Implementation of this alternative method proved to be successful and was recognized as an opportunity for future water main installation work.
