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
Largest Australian polymer lining
drinking water project
has secured a $4mn contract with South
Australia’s water utility corporation, SAWater,
to perform the largest polymer lining drinking
water project to be undertaken in Australia.
The 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 which runs
beneath one of the busiest
roads in Adelaide.
Stephen Barnes,
managing director at
Swagelining Limited,
said, “Our patented
Swagelining™ techn-
ology 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 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 commented, “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.”
