HYDRAULIC SERVICES.
1.0 SCOPE OF WORKS and SERVICES CONNECTIONS

The Hydraulic Services works shall reflect compliance to recognised professional standards and the
following documents :-
        
 Queensland Sewerage and Water Supply Act and Associated By-Laws;
        
 Authority Requirements and Noosa Shire Council and Unity Water Regulations;
        
 National Construction Code of Australia; and
        
 All relevant Australian Standards as listed in the following document text.

The Scope of Works encompassed under the Hydraulic Services area shall include the following :-

 Sewer/House Drainage : Inground house drainage piping system that shall collect all sanitary
  plumbing stacks and discharge all house drainage to a sewer pump station on site that shall then
  discharge via a sewer rising main to the Unity Water Sewer Rising main infrastructure with
  connection to Unity Water’s infrastructure arranged by the civil discipline. All internal house
  drainage and any required reflux valves shall be supplied and installed as part of the hydraulic
  services scope, and close liaison shall occur with the Civil Discipline in relation to the location of
  the pump station and required sewer rising main for discharge.

    It is noted that the existing Unity Water rising main is located to the north of the site in Rose
    Gum Road.

 Sanitary Plumbing : Comprises the soil and waste piping from the sanitary fixtures to the
  inground house drainage system via the stack/drainage dropper system.

 Trade Waste Drainage : Trade waste drainage piping system collecting from the trade waste
  sanitary plumbing & discharging to new grease interceptor traps to service the central kitchen
  area, and any internal/local kitchenettes to ensure that any waste water has all grease and oils
  removed prior to discharge to the pump station and rising main.

 Trade Waste Plumbing : Trade waste plumbing pipework system encompassing the provision of
  connection points to the kitchen and kitchenette areas of the development.

 Domestic Cold Water Service : It is important to highlight at the outset that there is no Unity
  Water / Council water main infrastructure in the surrounding streets/areas, and thus, the site shall
  have to be self-sufficient with regards to domestic water services.

    Given the proposed staging for the development, and given the gradient of the land, the site is
    ideally structured for water harvesting. As the proposed accommodation dwellings will be
    elevated, it is noted that rainwater harvesting tanks could be located in the undercroft of the
    buildings, and such a location positions the tanks in an ideal location to receive roof drainage
    directly from the roof areas of individual buildings. Alternately, the tanks could be located
    external to the building footprint, but the tanks will be a crucial source of water for the site.

    The harvested rainwater can then be reticulated directly back to each individual building to
    provide water for toilet flushing.
