Wannon Water rolls out $2.3 million sewer rehabilitation program

12 April 2017

Wannon Water is currently rolling out its largest ever sewer rehabilitation program.

The multi-million dollar project will improve the functionality and long-term reliability of the sewer network throughout several south-west Victorian localities.

Company Abergeldie has been awarded the $2.3 million contract to upgrade more than 16 kilometres of sewer pipes in Coleraine, Casterton, Hamilton, Portland, Warrnambool and Camperdown.

Wannon Water’s Project Manager – Asset Creation, Tamara Bull said the technology used to upgrade the sewer pipes is quite innovative.

“Abergeldie is an industry leader for sewer rehabilitation programs,” Ms Bull said. “It is a fantastic opportunity for our region to be using such cutting-edge practices”.

The initial stages of the process include inspecting the existing pipes with cameras, cleaning and necessary repairs.

Ms Bull said sewer lines are then plugged to stop sewage flows and a PVC liner is inserted into the pipes and heated with steam to ensure it can be easily guided through the existing sewer.

“Once the liner is in position, it is expanded to full size and cool air is added to set the liner. A robotic cutter travels the length of the pipe to reopen property connections and install a connection seal.

“There should be no interruption to services for customers, however, access to certain properties may be required. Property owners will be notified by Abergeldie according to the schedule of works.”

Ms Bull said the program is scheduled for completion in late June. “It is one of the many ways that Wannon Water is maintaining critical infrastructure throughout the region”.
