How to prepare for the installation between two existing DN 1200 sewer manholes? Is it necessary to dismantle the well? How big of a trench do you need to prepare to put a drilling rig in it?

There is practically no need to do anything on site. The design of the machines allows them to be introduced through a typical DN600 manhole, and then installed and operated from a typical DN 1200 manhole. Compared to other trenchless technologies, in the case of the Gravity Drilling Rig, all work is carried out from well to well, without any interference with the existing road or other infrastructure. During the works, it is only necessary to ensure that the lanes with sewage manholes can be turned off.
