Green infrastructure underground more than a pipe dream

Greenhouse gas emissions from the installation of both large and small-scale underground piping infrastructure can now be significantly decreased while increasing the speed of construction and minimizing disruption aboveground– all thanks to the latest innovations in methodology known as pipe-jacking or trenchless installation. Dr. Mark Knight, executive director at the Centre for Advancement of Trenchless Technology (CATT) at the University of Waterloo, said the technique is becoming increasingly popular due to its environmentally friendly benefits. Based on a study he conducted for the Brazilian Congress of Trenchless Technology in 2008, he calculated that switching to trenchless installation or restorations of sewer, water main and other various piping projects could reduce carbon emissions by up to 98 per cent. Trenchless installation method involves the use of powerful hydraulic jacks to push the pipes into the ground behind a shield while excavation is taking place within the shield. This causes very little to almost no disruption aboveground, and can be completed much faster than the traditional installation method that requires the use of trenches.
