Moyne mains under the microscope

27 March 2015

Eight kilometres of Port Fairy’s underground will be in the spotlight next week when Wannon Water’s proactive Sewer Inspection Program comes to town.

Wannon Water Managing Director Grant Green said the program involves deploying state-of-the-art robotic technology mounted with adjustable Closed-Circuit Television (CCTV) cameras to take a close look at the condition of the town’s sewer network.

“As sewer mains are located underground, it can be a challenge to determine what sort of condition they are in,” Mr Green said.

“This robotic technology allows us to look closely inside the pipes to see if there are any maintenance or structural issues without having to dig deep trenches to access the pipes.

“The CCTV inspections reveal the general condition of the pipes and the exact location of any erosion, silt build-up, cracks or intruding tree roots.

“If we detect any concerns we can then address them before they cause long-term asset damage or disruption to the sewerage services we provide to our customers in Port Fairy.”

Following the CCTV inspections, the technology can then clean inside the pipes and remove any tree roots or other material that might be reducing the flow of sewage.

The Sewer Inspection Program also provides Wannon Water with valuable information to help plan future sewer replacements and maintenance programs more efficiently.

The Port Fairy sewer inspections are expected to take approximately six weeks to complete and not cause any disruption to sewerage services.

In January 2015, Wannon Water inspected more than five kilometres of sewer mains in Koroit and cleared materials from some sections of pipe to improve the flow of sewage. Overall, the inspection confirmed that the Koroit sewer network continues to perform well.

In the current financial year Wannon Water will inspect and clean more than 45 kilometres of sewer mains in 11 towns across its service region using the CCTV technology.
