Adelaide project: the largest drinking water Swagelining project to date

Largest ever Australian polymer lining drinking water project takes shape

Swagelining Limited specialises in the control and prevention of internal corrosion in new and existing pipelines. The company uses polymer lining technologies developed from a concept originally created by British Gas and United Utilities. The company’s official Australian partner, ITS Trenchless, has announced that it has secured a $4mn contract with South Australia’s water utility corporation, SA Water, to perform the largest polymer lining drinking water project to be undertaken in Australia. The £2.5mn contract, which is now underway, will take approximately four months to complete. The project involves lining 4,630m of existing 24" nominal diameter water main that runs beneath one of the busiest roads in

Adelaide. Stephen Barnes, managing director at Swagelining Limited said, “Our patented Swagelining™ technology was originally developed specifically for rehabilitating utility pipes in challenging locations, such as beneath busy roads. “The Swagelining system is highly versatile with liner thickness varying from project to project. In the case of the Adelaide project a 594mm polyethylene (PE) 100 liner with a wall thickness of 56mm is being used to meet the client’s requirement for a liner with full structural capability. “This is in contrast to another water project recently completed in the UK where the requirement was for a thin semi-structural liner, which saw us install a 1,016mm PE100 liner with a wall thickness of only 20mm.”

Swagelining Limited’s bespoke software package, which enables the optimum liner size to be selected to achieve maximum pull length, established that pull lengths of over 600m can be achieved for the Adelaide project, further minimising excavations and disruption. Mr Barnes continued, “Unlike open trenching methods, Swagelining has minimum impact not only on the community, but offers significant environmental benefits as well. These include a reduction in raw material usage, less waste to be disposed of, lower noise levels, less dust, and the ability to complete the project within a short time frame.”
