Green Square stormwater drain project


Sydney Water and the City of Sydney are pleased to advise that work to build a 2 kilometre underground stormwater drain from Epsom Road, Zetland to the existing stormwater system at Alexandra Canal is progressing well.

Green Square is one of the fastest growing areas in Sydney and includes the suburbs of Beaconsfield and Zetland, and parts of Rosebery, Alexandria and Waterloo. The area sits on a floodplain known as the Waterloo Swamp. The new drain is essential to reduce hazardous flooding in and around the new Green Square Town Centre and enable further development. Construction of the drain is due to be finished by mid 2018.

A better Green Square
The Green Square stormwater drain is the first major infrastructure project in Green Square. It is a key element of Sydney Water and the City of Sydney’s commitment to sustainable urban renewal and liveable cities.

We have formed an Alliance with UGL Engineering, Seymour Whyte Constructions, Parsons Brinckerhoff Australia and RPS Manidis Roberts to deliver this project.

A better stormwater system
The new stormwater drain will
  • significantly reduce flooding in the Green Square area, particularly at Joynton Avenue and on Botany Road, Zetland; and
  • allow the development of the Green Square Town Centre – a major new residential, retail and cultural hub.
Where will it go?
We considered several routes for the underground drain when preparing the Review of Environmental Factors (REF). The route, from Link Road to Alexandra Canal, was chosen to minimise impact on residents, businesses and the environment. Most of this route runs through or under property owned by the City of Sydney and along Sydney Water’s Alexandra Canal easement.

    Huntley Street work delays

    Work to build the Alexandria section of the Green Square stormwater drain is continuing.

    In mid-2016 we closed westbound traffic flow on Huntley Street. The close proximity of the services under the bridge, the complexity of the work and the number of significant infrastructure projects underway in Sydney, limiting the number of specialist workers available, has delayed our work.

    One-way traffic flow on Huntley Street will now continue until mid-November 2017.

    As part of the Green Square stormwater drain project, we’re building a 350 metre long shared path. The path will be open to the public for use by both pedestrians and bike riders.

    The path will be located along the eastern side of the Sheas Creek stormwater channel, between Maddox Street and the start of Alexandra Canal, to the south of Huntley Street.The Maddox Street to Alexandra Canal shared path is part of a long-term commitment by both state and local governments to create the Alexandra Canal Path, which will eventually run along the entire length of the canal.

    Future stages of the Alexandra Canal Path will link to the Cooks River cycleway and cycleway network further south. This includes connecting with the new cycleway and pedestrian bridge proposed by WestConnex over the Alexandra Canal at Campbell Road, Alexandria.

    Planning for this section of the path began in late February 2015.

    We’ll release a newsletter with the shared path design soon. In the meantime, the Review of Environmental Factors addendum provides information and is the planning and approval document for this part of the project.

    The shared path is being built by the DG Alliance, the team delivering the Green Square Stormwater Drain Project for Sydney Water and the City of Sydney.

    If you have any questions about the work, please feel free to call us on 1300 883 648 or email us at stormwater@dgalliance.com.au

  • Tree removal in Perry Park – July 2016

    over 1 year ago

    Work to build the section of the stormwater drain passing under Perry Park is ongoing, but progress has been slower than expected because one of our microtunneling machines is stuck in the ground on the Bourke Road side of the park.

    We’ll soon start work to dig the machine out. Unfortunately, we’ll need to remove eleven trees in the park to do this, including Two Hill’s Weeping Figs.

    More information about where the work will be happening, what it will involve and the trees impacted can be found in the community notification letter.
