Upgrade to sewer system to fix cracks and leaks

The Fraser Coast Regional Council is overseeing a $6.1 million sewer relining and manhole refurbishment program in Local Government Areas across the Wide Bay Burnett Region.

Fraser Coast Water and Waste Services Director Mark Vanner said about 2kms of the Fraser Coast region’s sewers would be relined over the next two years to better maintain and improve the region’s wastewater network.

“Relining is a cost-effective way to renew the gravity sewer systems without the need to dig up existing sewers and manholes to replace them,” he said.

“Combining our works programmes across the Wide Bay Burnett Councils allows us to increase efficiency and lower pricing”.

The project includes cleaning the sewer gravity mains, pre and post lining CCTV surveys of the sewers and 3D imagery of manholes as well as relining the sewers to fix breaks, cracks and leaks.

“Using 3D Images and CCTV will allow us to create a digital version of the manholes and sewers which will allow us to see the issues better,” Mr Vanner said.

Relining Solutions Pty Ltd has been awarded the sewer relining contract while Infrastructure Rehabilitation Services Pty Ltd has been awarded the manhole refurbishment contract.

Mr Vanner said there were more than 14,000 sewer manholes with a number of these being constructed over 80 years ago. 

“The manhole refurbishment program involves fixing cracks in the manhole walls caused by ground movement and degradation of the concrete walls and leaks,” he said.

“A key priority for Council is to effectively manage and maintain our assets, and that’s what these two programs seek to achieve.”
