Water Extraction Systems

 

The WExTech™ systems are designed to locate water in live gas pipes, remove the water, and recycle the gas back into the network. There is a WExTech™ system for every type and size of pipe.

Key benefits include:

  • Significantly reduces the number excavations needed compared to traditional methods of locating the source of water ingress.
  • Accurately locate the source of ingress to enable permanent repair and avoid repeat visits.
  • Unique closed-loop system recycles the gas back into the main or service.
  • Fully compatible with Synthocam3 live gas CCTV systems used by all UK gas networks, keeping investment cost to a minimum.

System options for Mains

There are two versions of the WExTech™ Mains units. The WExTech M-T1 (Trailer Unit) which is on a self-contained round carousel with the benefit of rough surface wheels. The alternative is WExTech M-V1 (Van Unit) which is designed to fit between the racking on a standard van and can be split into two parts which can be maneuvered with a two man lift.
