Water Extraction Systems

Water Extraction diagram

Water Extraction Systems – simultaneously locate and remove water from live gas mains and services whilst recycling the gas back into the main or service.

This newly-approved innovative technology locates the source of ingress, removes water, and recycles gas back into the main or service, reducing excavations and impact on the consumer.

Optimum system configurations have been engineered to suit Tier 1 or Tier 2 mains, plus a small portable system for service pipework.

Key benefits include:

  • Significantly reduces quantity of excavations required when 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 to recycle 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.

Systems work on the principle of safe access into the live main / service, live visual display as the system moves through the main / service until the source of water ingress is found, and simultaneous removal of any water using an innovative closed-loop vacuum system which separates water from gas and then returns the gas back into the main.

System options for Mains

Systems are available for Tier 1 or Tier 2 mains, and have the option of gas recycle and / or connection to bowser system (such as Allen-Taylor trailer unit) for removal of larger water volumes.

Bespoke customised versions are available to suit specific network / contractor requirements.

System options for Services

The water extraction systems for live gas services are portable and simple to use – a compact system designed to be carried by engineers for rapid resolution of supply interruptions caused by water ingress into the service pipework.
