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.
