A $3.4 million project to improve wastewater pipes in the town of Cambridge in Western Australia has been completed, with the investment set to extend the life of the pipes by at least 50 years.
Water Corporation, enlisting the assistance of Interflow, refurbished 4.4km of wastewater pipe in Floreat, City Beach, Wembley and Wembley Downs.
The project, which began in March 2019 and finished early July, forms part of an ongoing program by the State Government to reline and refurbish wastewater pipes across Western Australia.
The refurbishment project in Cambridge involved trenchless technology to minimise the impact on the community.
The technology works by inserting a plastic strip liner inside an existing wastewater pipe via access chambers and winding it down the length of the pipe route. The wound plastic liner is then expanded to fit tightly within the walls of the existing pipe to provide a smooth finish.
This method helps prevent pipeline corrosion, reduce the likelihood of blockages and extend the life of the infrastructure by at least five decades.
Since 2015, around 60km of wastewater pipeline across Western Australia has been refurbished through the ongoing program.
Water Minister, Dave Kelly, said he was pleased that the project could be completed on time and under budget, benefitting the whole community.
“Relining old wastewater pipes is important to protect the local wastewater systems and the health of the community and environment,” Mr Kelly 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.”
