The combined Sewer and Storm Water Pipe Rehabilitation Project awarded to Interflow by Gladstone City council has been delivered with enhanced new innovations in trenchless technology.
The influx of new and innovative ideas has kept the up the rapid momentum in the evolution of trenchless technologies. Continuing to push the boundaries within this field, specialist in pipeline renewal solutions, Interflow, has developed a new liner which is one of the company’s most robust and adaptable solutions to-date.
The new liner has been specifically designed for installation through dips and bends in an underground asset. Interflow’s Project Engineer, Brett Elsum states it is also a simple method for restoring the pipeline’s structural integrity and hydraulic capacity, as well as preventing unwanted infiltration and exfiltration.
Interflow’s Project Manager, Shaun Corrie, explains the impact this new technology is having on the project and for the client.
“Given most of the lines are consecutive, we can actually wind through manholes and cut out the liner. This has resulted in much faster productivity in terms of installation, without compromising the overall quality,” he says.
“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, which means that the physical characteristics are unaltered during installation. Unlike soft liners that require curing, the is no risk of any chemical leaks that are harmful to the environment. Not only does this reduce the product’s carbon footprint and minimises community disruption, it also creates a safer working space for operators.
The company’s Head Foreman for this project, Justin Norton, emphasises the importance of enabling a safe environment for his crew.
“I take safety with utmost respect, so it becomes foremost and number one,” he says.
“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 works carried out reflect Interflow’s vision of constantly pushing the status quo to meet and exceed expectations for key stakeholders.
“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,” says Interflow’s Business Development Manager, Mr. John Phillips.
“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 commenced in April, 2019 and are projected for completion by August, 2019. As a result of this renewal project, Gladstone Regional Council’s sewer and stormwater assets will have an operational span of 100 years.
