How a Very Long Storm Main Pipe Is Pulled Deep Underground Without Digging a Trench

How do you install a 61-metre-long storm pipe beneath a major roadway without digging a trench? Sandpiper, in partnership with Directional Mining & Drilling, just installed 61 metres of 24-inch HDPE storm pipe using Horizontal Directional Drilling (HDD) beneath Stewardson Way in New Westminster on behalf of the City of New Westminster, within the Heritage Permit Area. Before the pullback begins, our crew fuses individual HDPE pipe sections together on site, creating one continuous 61-metre-long pipe that can be installed in a single pull beneath the roadway. This trenchless installation method allows one of the city's busiest transportation corridors to remain open while minimizing disruption to residents, businesses, and traffic. Here is the video of how we drilled the initial pilot hole under the road before it is enlarged for the pipe pull:    • What Is Trenchless Utility Installation—an...   Thank you Shawn Sedlar, Project Manager at Directional Mining & Drilling Ltd., for giving professionally detailed answers to various viewer questions below! https://www.sandpiper.bc.ca https://www.directional.ca
