It can be seen in Figure 8 that there is sufficient room to position the wastewater land application area in
accordance with the siting requirements of Noosa Council, including being located on land not subjected to
flooding (at least immunity to 1 in 100 year event), 2 m and 4 m setbacks from side and lower boundaries, and
a 50 m setback from the existing dam.

                                                                                                      Dam

Siting of the land application systems should generally be in accordance with the horizontal and vertical
setback distances recommended in Table R1 of AS1547:2012, as summarised in Table 3.
