Two Sydney Water projects were recognised as best in class at the Australasian Society of Trenchless Technology Awards held in Sydney.
Sydney Water contractor Interflow Pty Ltd won Project of the Year – New Installation for its work in lining large sections of sewer mains in Lidcombe, Auburn and Granville.
This two-year project involved the structural lining of some 1.2 kilometres of 900mm diameter reinforced concrete sewer constructed in a tunnel around 1922.
The importance of the sewer main, serving several upstream pumping stations, meant it could not be taken out of service at any time during the works.
Another Sydney Water partner, Kembla Watertech, claimed Project of the Year – Rehabilitation for its work on the Bennelong stormwater project.
Kembla Watertech successfully rehabilitated an important section of Australia’s historical drainage system in inner city Sydney – the Bennelong stormwater channel – which was the first oviform combined sewer/stormwater system constructed in Sydney in 1857.
“Sydney Water was proud to partner with Interflow and Kembla Watertech on these complex projects which required industry leading trenchless technology to minimise disruption and impact on our customers,” said Sydney Water Managing Director Kevin Young.
