Client: Noosa Shire Council                        Location: 62 Lake Macdonald Drive, Cooroy


1.0 INTRODUCTION
This report demonstrates the findings of a water supply and sewer network analysis undertaken for
the proposed subdivision for residential housing at 62 Lake Macdonald Drive, Cooroy as requested
in the service advice notice (SAN) from Unitywater shown in Appendix D.

Using the InfoWater and InfoSWMM models provided by Unitywater on the 17th July 2023 the
proposed development water and sewer infrastructure was added to the respective models to
determine the impacts of the proposed development on the surrounding water and sewer network.

The site is located at 62 Lake Macdonald Drive, Cooroy. The real property description is Lot 105
SP118458. The total site area is approximately 3.54 hectares. The site currently consists of a
storage shed, vegetation and open space. The proposed development application is for a lot
reconfiguration for residential purposes. A site locality plan is shown in Figure 1.

The development is located within water DMA zone COORO (“the DMA”). The development
sewerage will drain to the existing sewer pump station (SPS) CRY020 before discharging to the
Cooroy Sewage Treatment plant (STP-CRY001). The scope of the sewer analysis is from the
development connection point to pump station CRY020.
