Worlds Largest Spiral Wound Pipe Renewal - NGRS Project - Interflow

Exhibited at Sydney’s Powerhouse Museum, we installed the world’s longest and largest continuous spirally wound pipe liner. To give you an idea of its size, the liner was 633m long, 2.4 metres in diameter, and weighed almost 100 tonnes!
As part of a major rehabilitation project in Sydney, we successfully renewed an integral part of the city’s sewer system using trenchless technology. This innovative method gave ground crews the ability to conduct vital sewer repairs, without digging up established roads and infrastructure, minimising disturbances for surrounding communities and the environment.
