Water Corporation has renovated 4.4 km of wastewater pipes thanks to a AU$3.4 million investment from the McGowan Government as part of an ongoing effort to reline and refurbish wastewater infrastructure across Western Australia.
To complete the works, the utility contracted Interflow to insert a plastic strip liner inside the existing wastewater pipe via access chambers, which was then wound down the length of pipe.
The spiral wound liner was then expanded to fit tightly within the pipe walls, preventing corrosion, reducing the likelihood of a blockage and extending the life of the pipeline by approximately 50 years.
WA Water Minister Dave Kelly said the project was completed on time and under budget.
“Relining old wastewater pipes is important to protect the local wastewater systems and the health of the community and environment,” he said.
“Trenchless technology was used to reline wastewater pipes where possible, to minimise the impact on the community by reducing the need for extensive excavation.
“I thank the community for its patience while Water Corporation carried out this essential work.”
Around 40 local workers were engaged to complete the project.
