Green Square Named Engineering Excellence Award Finalist

Congratulations to the Green Square Stormwater Drain project on being recognised as a finalist in the Australian Engineering Excellence Award 2020. The projects named as finalists represent outstanding achievement in engineering and demonstrate the invaluable contribution engineering makes to the economy, community and the environment.

As one of New South Wales’ fastest-growing populations and one of Australia’s largest urban renewal projects in Sydney, this $13 billion redevelopment will transform Green Square from an industrial hub into a vibrant major retail, residential and cultural hub. By 2030, the urban renewal area will create 30,500 new residential dwellings to cope with an anticipated population of 61,000 and 22,000 new workers. Green Square is setting a benchmark for the future of sustainable communities.




Together with Sydney Water and the City of Sydney and as part of the Drying Green Alliance with UGL and Seymour Whyte, WSP provided technical and design services and construction support for the new stormwater drain, which reduces the flood hazard in Green Square using microtunnelling to install twin and triple 1800mm diameter pipes over 2km in length.


Nick Taylor, WSP’s Principal Civil Engineer says, “This is a complex project that is critical to reducing the high-hazard flooding to deliver a liveable urban renewal for this inner-city area. It was successfully delivered through the cooperation of local and state government authorities, construction contractors and WSP through an alliance framework.


“The most beneficial and cost-effective infrastructure is being built because of the thorough planning process and rigorous hydraulic modelling that WSP undertook in optimising the final design. We are proud to be recognised by our industry in delivering a sustainable future for Sydney’s thriving communities.”
