UV CIPP LINING IN SYDNEY'S CBD In January this year, Sydney Water awarded Kembla the contract to repair heritage-listed concrete oviform stormwater assets in high impact locations in Sydney's CBD, including Pitt Street Mall. In late March, Kembla Watertech successfully completed its first Ultra Violet (UV) cured CIPP installation at night in the middle of Sydney's CBD. Kembla's CIPP team installed a 110-metre length of UV liner in a dilapidated brick 1070mm x 710mm oviform pipe from an access chamber located in the centre of Elizabeth Street. Kembla Watertech is installing UV-cured CIPP liners in over a kilometre of Sydney Water's stormwater assets, as well as an additional 300 metres of wastewater aqueduct to be lined in Enfield, in Sydney's southwest. This aqueduct is located through residential backyards and business areas with a high civil component adding to the community impacts. Kembla's CIPP team has nearly 20 years' experience installing liners across metropolitan Sydney, the Hunter region, Victoria and Queensland. UV lining technology Kembla Project Manager, Paul Propper, says: "Kembla is working closely with experienced staff at our German partner company and three representatives flew to Sydney to assist with the first installation. Our German partner company has over 10 years' experience in UV curing systems, which have multiple benefits, including a smaller site footprint, less traffic disruption, quieter machinery, and reduced styrene odours." External monitoring plays a large part in the quality assurance of our German partner company liners, including DIBT (German Institute for Construction Technology). Three Kembla staff gained DIBT technician accreditation in Germany, with more to follow. "Kembla is committed to training its staff with the technical skills to provide quality, reliable products to its clients," Paul explains. "Attaining DIBT accreditation is highly esteemed within the European market." At present, the product is ideal for large diameter and oviform pipes and all liners must be imported from Germany as there is no production facility in Australia. Kembla's commitment to on-time delivery is demonstrated by expedited air freight shipping of the eight-tonne liner used in the first Elizabeth Street installation to meet strict project timeframes. Community and heritage impacts "A major advantage to this lining system is the reduction of time on-site compared to conventional CIPP installation," says Paul. "With UV installation we were able to reduce the time spent on-site. "With our first installation, we knew there were going to be some impacts on local stakeholders, so we consulted with a multitude of stakeholders to ensure our impact on them was minimised." With Sydney Water's assistance, Kembla worked closely with Sydney Buses, the Roads and Maritime Services, City of Sydney Council, local hotels and building managers to ensure the project was executed seamlessly. This consultation is ongoing throughout the project to ensure stakeholder satisfaction. Due to the age and significance of Sydney Water's heritage-listed stormwater assets, heritage approvals were required before conducting any work. These are some of Sydney Water's oldest assets, built in 1857 to service Sydney's growing CBD. What's next? Moving on from this site, Kembla's CIPP team are currently traversing and investigating the remaining assets in Elizabeth and Pitt Streets. The project team is continuing to meet with high level stakeholders to ensure all community, stakeholder and government requirements are met.
