Metropolitan Adelaide stormwater reuse project
Adelaide, South Australia
Total funding: $6.91 million with a contribution of $2.76 million from the Australian Government, $2.35 million from the South Australian Government and $1.8 million from three metropolitan golf clubs.
About the project
The project, which is now complete, demonstrates the value of stormwater harvesting and reuse. Constructed wetlands collect stormwater and filter much of the pollution that would otherwise run into the Gulf St Vincent. Urban stormwater is diverted to wetlands constructed at the Grange, Royal Adelaide and Glenelg golf clubs. The stormwater from the wetlands is pumped, through bores, into an underground aquifer where it is stored until required for irrigation.
Project benefits
The Metropolitan Adelaide stormwater reuse project has:
- saved 1000 megalitres of water a year by using stormwater to replace potable water used for irrigation
- reduced the discharge of nutrients by capturing urban stormwater that would otherwise run into the Gulf St Vincent
- improved the condition of beaches around outfall areas
- decreased the salinity of underground water supplies by adding filtered stormwater
- provided certainty for the irrigation needs of three internationally-rated and important golf courses, and
- enhanced local biodiversity through the construction of wetlands.
The project advances the National Water Initiative objective of encouraging reuse and recycling.
Water Smart Australia projects are funded by the Australian Government's Water for the Future initiative.
