SEWERS UP TO 205 METRES LONG, 18 METRES DEEP LINED FOR MELBOURNE WATER
Meeting the requirements of Melbourne Water on a recent project meant installing liners into very deep sewers with long lengths. To complicate matters, installation had to be completed in one shift, under a busy Melbourne road.
For the longest pipeline section, 205 metres in length at a depth of 8.6 metres, more time was needed, and so work was completed at night. This was one of the longest single lengths of Rib Loc Expanda Pipe installed by Interflow. It required a specially manufactured spool of profile containing sufficient length to enable lining to be completed without joins.
The Interflow crew commenced work at 7.00pm. By 5.00am the next morning, the site was again clear. During this time they had:
· CCTV surveyed the 205 metre pipeline prior to cleaning.
· Cleaned the line.
· Performed a second CCTV survey to check quality of cleaning.
· Profiled the pipe diameter along the entire pipeline length.
· Installed and Expanded the Rib Loc Expanda Pipe liner.
· Cut a lateral connection.
· Restored the pipeline to service.
The next night was used to seal the lateral connection, carry out ovality checks of the lined pipe to check the minimum specified diameter and perform final CCTV.
Work on this, and other pipelines on the project, was completed on time and to the full satisfaction of Melbourne Water.
