Once the water was under control, the microtunneller was set up to line and grade and the 150mm PVC boring pipe was installed to within millimetre accuracy. The whole operation including the installation of pits, well point dewatering and microtunneling of the sewer took less than 3 days and proved to be a great success.
Another successful job completed by Ground Water Control, thanks to their new acquisition, a Pilot Tube Microtunneling B750 with 50T Push and 3500Nm of Torque.
