Long Pull Avoids Draining Major Wetland
Sliplining is completed by installing a smaller, HDPE pipe into a larger host pipe, grouting the annular space between the two pipes, and sealing the ends. The trenchless method is generally a cost-effective rehabilitation method to replace water and sewer force mains.
The original design was to drain the entire wetland that had formed since the original construction of the 36-inch water main and split the slip lining into multiple sections. However, Murphy Pipelines designed and sliplined the entire length in one pull allowing the wetland to remain untouched.
Powell River, BC located in inaccessible area requiring pipe, equipment and workers reach only by ferries.
Wellpoints set up at insertion pit.
Pull head fused on. Long sections of HDPE pipe staged on old mining road.
Pulling winch set up ready to start sliplining.
