Stormwater drainage network upgrades


In March 2019, the Council resolved to invest $38.4 million across a 15 year project to upgrade the City’s stormwater drainage network. 2019 marks the first year of the program which will address and reduce the impacts of flooding, helping to protect residents, their homes and properties, as well as the City’s assets such as footpaths, kerbing and street trees.

The City’s stormwater drainage network is one of many infrastructure assets which is provided and maintained by the Council for the community. The network removes surface water from roadways and provides appropriate levels of flood protection throughout the City.

In 2019–2020, the program includes the following projects:

  • increasing the capacity and efficiency of Second Creek at Linde Reserve, Stepney
  • upgrading the capacity of Third Creek from Lewis Road to Payneham Road, Payneham.

Other projects which will be undertaken over the 15 year program include the following:

  • Third Creek: Lewis Road to Bridge Street, Payneham First Creek: North Terrace to Hackney Road, Hackney
  • Laura Street: Second Creek to Clifton Street, Stepney Portrush Road to Canterbury Avenue, Trinity Gardens.

The scheduling of these projects will be undertaken following the development of detail designs, funding arrangements and the completion of other works.

In addition, the Council will also undertake the following works as part of the 15 year program:

  • upgrade the capacity of inlets along First Creek at Kent Town
  • increase the capacity of First Creek between Sydenham Road and Charles Street, Norwood
  • direct run-off into First Creek at The Crescent and Dean Grove, Marryatville
  • increase the capacity of Third Creek from Bridge Road to Rosella Street and Rosella Street to John Street and John Street to Marian Road, Payneham
  • increase the capacity of the Gage Street and Sommers Avenue culvert crossing at Third Creek, Firle
  • upgrade the drainage capacity in Clifton Street and Jones Street, Maylands
  • increase the standard of the low points in Williams Street and Gardner Street to Seventh Avenue, St Morris
  • improve the overland flow path on Green Street, St Morris
  • construct new drainage along Portrush Road, Victoria Street, Payneham Road and Lambert Road to the River Torrens, Payneham/Joslin
  • extend pipes in Seventh Avenue along St Peters Street to Eighth Avenue, St Peters
  • construct raised platforms at streets intersecting with Wicks Avenue, Felixstow.

A number of additional small projects have also been included in the 15 year program.
