About the project:

Project location: Onkaparinga, South Australia

Funding recipients: City of Onkaparinga

Total Australian Government funding: $14.97 million (GST exclusive)

Water savings: up to 1.3 GL/yr

The project will offset up to 1.3 gigalitres per year (GL/yr) of potable demands across the City of Onkaparinga. This will be achieved through the construction of stormwater harvesting and reuse infrastructure including wetlands, and managed aquifer recharge at five sites. Stormwater will be diverted into off stream wetlands, treated and then injected into fractured rock aquifers and distributed to the identified demand nodes in the vicinity of the scheme. The water will be fit for purpose for open space irrigation. The five sites are: Reynella East; Pedler Creek Reserve; Port Willunga; Aberfoyle Park; and Chandler's Hill Reserve.

Project benefits/objectives:

  • Construct stormwater harvesting and reuse infrastructure that has the capacity to reduce potable water demand by up to 1.3 GL/yr by replacing mains supply with treated stormwater.
  • Promote the sustainable use of alternative water supplies in the Adelaide urban environment.

Project progress:

The project is due for completion by October 2013.
