Coleraine’s sewer network gets a check-up

21 January 2015

More than three kilometres of Coleraine’s underground sewer network is in the limelight this week with Wannon Water’s proactive Sewer Inspection Program coming 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 Coleraine.”

Following the CCTV inspections, the technology can also 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 Coleraine sewer inspections are expected to take approximately three weeks to complete and not cause any disruption to sewerage services.

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.
