                 WATER INFRASTRUCTURE)
5.1              Services Advice Notice
                 Hyder Consulting received a Services Advice Notice (SAN) regarding the servicing of the
                 proposed development for water and sewer services from Unity Water which states that the
                 existing infrastructure has sufficient capacity to service the proposed development. Refer to
                 Appendix E for the Notice.


5.2              Water Supply
5.2.1            Existing Water Supply Infrastructure
                 Unity Water DBYD maps indicate that there is a potable water reticulation main located within
                 the Lionel Donovan Drive and Eumundi Noose Road. Both pipes are 100mm diameter mains.
                 There are multiple hydrants and valves on the main. Lot 4SP159610 takes service from the
                 main in Eumundi Noosa Road and Lot 31SP170751 is intended to be serviced by the main in
                 Lionel Donovan Drive.

                 In the current Priority Infrastructure Plan (PIP), Noosa Council have not indicated any priority
                 water supply infrastructure works within the area surrounding the subject site.

                 For details of the surrounding water infrastructure refer to Unity Water DBYD results in
                 Appendix E.

5.2.2            Proposed Water Supply Infrastructure
                 It is proposed to maintain the existing water connections to the site on Eumundi Noosa Road
                 and Lionel Donovan Drive. Lot 4 SP159610 will maintain connection to the 100mm diameter
                 main on Eumundi Noosa Road, and Lot 31 SP170751 will maintain connection to the 100mm
                 diameter main on Lionel Donovan Drive.

                 Unity Water’s SAN also advises that it may be necessary to upgrade the existing water
                 reticulation main to 150mm diameter (including hydrants) along Eumundi Noosa Road to allow
                 for sufficient fire flow. Hyder Consulting considers this to be an unnecessary burden on the
                 proposed development as the intended purpose for the site is largely consistent with the
                 planning scheme.

                 Additionally, Lot 4SP170751 is already used for industrial purposes, and there will be an
                 decrease in demand on the water infrastructure in Eumundi Noosa Road due to the proposed
                 development. Table 5.1 compares the existing and developed case demand over Lot
                 4SP159610.
