Total funding: Total project cost $4.5 million, with funding of $2.271 million from the Australian Government under the National Water Security Plan for Cities and Towns and the remaining funding provided by Whyalla City Council.

About the project

Whyalla City Council will utilise at least 350 million litres of treated wastewater each year to irrigate median strips, ovals, parks and reserves throughout Whyalla. The project involves the extension and connection of the existing reclaimed water pipe network from the SA Water Effluent Treatment Scheme to new and existing irrigation systems.

Project benefits

This project will:

  • save at least 265 million litres of potable water sourced from the River Murray each year
  • reduce current pollutant discharge into the fragile marine environment of Spencer Gulf, and
  • provide the community with green–turfed streetscapes, community spaces, parks and ovals.


The project commenced on 11 January 2011 and is scheduled for completion by 30 June 2012.
