Our services range from design and construction to commissioning and project management, ensuring that each project is completed in a seamless and efficient manner.


Our Technology

We harness a unique mix of technologies and solutions to ensure your system continuity during repairs. This includes hot tapping, flow stopping and s-gate valves.

Hot Tapping

Saltire Infrastructure utilises high-pressure rated Hot Tapping Equipment for the fast and safe installation of new branch connections and bypass mains, with the current capability to install DN25-DN400 offtakes.


Flow Stopping

Line Stopping allows works to be undertaken on water mains without interruption to customer supply. Deploying a stopper and bypass system, the rig set-up allows for sections of pipelines to be made dry allowing safe repair or replacement of the existing network.


S-Gate Valve

Saltire Infrastructure’s S-gate Valve System is a WSAA-approved live insertion valve system, designed to be used on live under pressure pipelines, providing mechanical isolation on the network to operator’s requirements and a future asset on the pipeline network to be used time and time again.


Live Pipeline Inspection

We can accurately identify and record leakage points in fully operational pipelines without disruption to water supply/ stakeholders. The technology also assists in commissioning works, surveying internal pipelines and identifying failure locations under pressure testing.
