Back Edinburgh Park North
 

Edinburgh Park North and South are significant in size, operate under gravity and can inject into aquifers near to where flows are treated. Existing wetlands in the lower end of the catchment (Kaurna Park, Springbank and Burton West) are assumed to be reconfigured to operate more effectively for the treatment of flows for a given area to provide the estimated treated flows. Gravity fed wetland systems are proposed to capture and treat flows. To store the treated flows ASR investigations undertaken at Edinburgh Parks North (a) and South (b), and at Kaurna Park showed that the T2 aquifer is well developed and homogeneous, with consistent properties that are well suited to ASR. These are:

  • Depth to top of aquifer: 117-120m below ground
  • Thickness: 47-60m.
  • High transmissivity.
