Metropolitan Adelaide Major Irrigator's Storm Water Reuse
Adelaide, South Australia
Australian Government Funding: $2,764,951
About the project
The project, which is now complete, demonstrates the value of storm water harvesting and reuse. Constructed wetlands collect storm water and filter much of the pollution that would otherwise run into the Gulf St Vincent. Urban storm water is diverted to wetlands constructed at the Grange, Royal Adelaide and Glenelg golf clubs. The storm water from the wetlands is pumped, through bores, into an underground aquifer where it is stored until required for irrigation.
Project benefits
The Metropolitan Adelaide storm water reuse project has:
- saved 1000 megalitres of water a year by using storm water to replace potable water used for irrigation
- reduced the discharge of nutrients by capturing urban storm water 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.
