We specialise in water and system continuity

Saltire is a water industry focused services provider that undertakes pipeline construction and repair works. We have highly experienced teams and technologies that focus on innovation, delivery and excellence. Repair work that has to be completed on any water utility can lead to service disruption to thousands of customers, including critical systems such as fire services, hospitals, schools, data centres and much more. Saltire Infrastructure’s technologies specialise live intervention and system continuity, to reduce or negate the disruption caused by these works.

Utilising hot-tapping, S-Gate valves and flow-stopping systems, Saltire can stop water flow within most pipeline networks and also by-pass or  redirect water flow to allow repairs and maintenance works to proceed without interruption. Saltire can also provide full turnkey project services, assist with scoping and design of works to ensure best fit scenarios for clients and stakeholders alike. Speak to one of our team members about how we can assist your project today.

Engineering Solutions

Our team has a combined over 60 years of pipeline and utilities experience. Whether your query is in relation to network pressure management, upgrades, trenchless technologies or unique pipeline products, feel free to contact us.



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.

J. CollierProject Leader - Water Corporation

I wanted to take a moment to express my appreciation for the excellent work your team did during the hot-tapping operations in Allanooka. The quality of work and professionalism exhibited by everyone on the team was truly impressive. We were particularly impressed with the care and precision with which all equipment was operated.
