Tunnelling moves, and so should its water treatment. Containerised, skid-mounted plant deploys in days, runs unattended and relocates from portal to shaft as the drive advances.
A tunnelling programme is not static: portals, shafts and compounds come and go as the drive advances. Fixed, civils-heavy treatment plant does not suit that, so we package tunnel water treatment into containerised and skid-mounted units that arrive ready to run, deploy in days, operate largely unattended and lift out to the next location when the work moves on. It is the practical way to keep treatment matched to a shifting site.
Rapid, Relocatable, Automated
Each unit is a complete treatment stage — buffering, clarification, pH correction, filtration — pre-built, wired and tested in the factory, needing only power, feed and discharge connections on site. Automation lets the plant run with minimal attendance, and standard interfaces let stages be combined or expanded as the duty changes. When a portal or shaft is finished, the units relocate rather than being demolished.
Factory-built units deploy in days with minimal site civils.
Lift out and move to the next portal or shaft as work advances.
Automation suits 24-hour drives with minimal staffing.
Stages combine and expand as the dewatering duty changes.
Matching a Shifting Site
Tunnelling sites change constantly; the treatment plant has to keep up without heavy rebuild each time.
Portals, shafts and compounds move as the drive advances.
Days, not weeks, to stand up treatment at a new location.
Compact, stackable units fit congested urban sites.
From Delivery to Relocation
Units are assembled, wired and wet-tested before delivery.
Power, feed and discharge connected on site in days.
The train is started and tuned to the actual water.
Automated, largely unattended operation through the drive.
Units lift out to the next portal or shaft.
