1.4 COLD WATER SERVICES

The potable and non-potable cold water services shall be sourced from a rainwater harvesting
methodology strategy, whereby all roofwater is captured and harvested in storage tanks, with
treatment applied commensurate with use. Low treatment will be provided for water to be used for
toilet flushing, whilst high treatment processes shall be applied for water that shall be consumed in
potable applications.

Furthermore, a bore shall be constructed on the site, and is proposed for supply of all non-potable
water services. However, further water testing of the bore water shall further confirm the
capacity/quality of such water to be used for other purposes – either with or without treatment.

The cold water system shall conform to the following Australian Standards :-

                AS 1167          Welding and Brazing – Filler Metals
                AS 1345          Identification of the Contents of Piping, Conduits and Ducts

The design shall encompass all piping, valves, unions, fittings, and sundry equipment to the
satisfaction of the Noosa Shire Council.

Water services pipework shall be as follows :-

           all 100mm (or larger) inground water service pipework shall be either copper or poly
            pipe suitably sized in accordance with the areas serviced;
           all inground water service pipework less than 100mm shall be copper. The size of such
            pipework shall be in accordance with the fixtures/areas being services;
           all water service pipework within buildings shall be copper. No pressurised services
            shall be located in slabs.
