Interflow using innovation to deliver Gladstone rehabilitation

Interflow is using innovative trenchless technologies to deliver a sewer and stormwater pipeline rehabilitation project for Gladstone City Council in Queensland.

To complete the project, pipeline renewal specialist Interflow is using a new liner, which is one of the company’s most robust and adaptable solutions to-date.

The liner has been specifically designed for installation through dips and bends in an underground asset.

According to the company, the liner is a simple method for restoring a pipeline’s structural integrity and hydraulic capacity, as well as preventing unwanted infiltration and exfiltration.

Interflow Project Manager Shaun Corrie said the new technology is already reaping benefits for the project and the client.

“Given most of the lines are consecutive, we can actually wind through manholes and cut out the liner,” he said.

“This has resulted in much faster productivity in terms of installation, without compromising the overall quality.

“As a consequence, the project will be delivered approximately three weeks earlier than programmed.”

There are two types of liners used for this project: both are installed by a mechanical process and do not require any curing, meaning the physical characteristics are unaltered during installation.

Unlike soft liners that require curing, there is no risk of any chemical leaks, which are harmful to the environment.

Not only does this reduce the product’s carbon footprint and minimise community disruption, it also creates a safer working space for operators.

Interflow Head Foreman Justin Norton these benefits contribute to a safer working conditions for his crew.

“I take safety with utmost respect, so it becomes foremost and number one,” he said.

“You need to start right from the bottom, all the way through to having safety control measures in place that protect crews and public.”

The project reflects Interflow’s vision of constantly pushing the status quo to meet and exceed expectations for key stakeholders.

Interflow Business Development Manager John Phillips said, “We are proud to be doing this work for this very important client and we’re able to mobilise our crew promptly to meet their expectations.

“The council has wisely chosen to combine the sewer and stormwater rehabilitation projects, which will ultimately lead to cost savings to the community.”

The works, which will extend the life of the council’s infrastructure by 100 years, commenced in April and are expected to be completed by August 2019.
