[Trenchless technology: an innovation From SADE]
"Trenchless" techniques represent the most striking innovation in this field. With this new technology, a work team can fit a new pipe or renew an existing pipe without opening trenches. Directional drilling, mini-tunnelling machines, remote-controlled robots, and various extraction and "place for place" replacement processes make it possible to reduce disturbance for residents near the worksite while preserving their living environment.
