               Condition 56

               Water quality and quantity

               Operating roof water harvesting tanks must be provided for the development. The tanks must be
               provided in accordance with an Operational Works approval and must include in particular:

                      a. a total tank capacity of 135,000 litres

                      b. a catchment of not less than 2,800m2 of the building roof area

                      c. re-use of harvested stormwater for non-potable outdoor uses including irrigation of
                         landscaped areas and swimming pool top-up.

               Applicant’s comments:

               The original rainwater harvesting tank volume was based on the evaporation rates calculated for
               a significantly larger pool surface area. The size of the swimming pools was reduced significantly
               as part of the minor change. In particular, the pool surface area has reduced by approximately 60%
               and a revised capacity of 54,000 litres reflects this proportional change.

               Although part of the landscaped areas within the hotel may be irrigated from the freshwater
               harvesting, a significant proportion on the landscaped areas would be irrigated from the Noosa
               Springs irrigation system that draws water from the freshwater lakes of Noosa Springs. It is noted
               that any rainwater not harvested and stored in the tank at the hotel would flow into the drainage
               system that eventually discharges into the freshwater lakes of Noosa Springs. Therefore, using
               that Noosa Springs lake water for irrigation purposes is making productive use of the rainwater
               harvested in another manner and does not require use of potable water.

               The combined roof areas of Pavilions 1 to 4 of the hotel has a total of 2,439m2 . Reducing the
               minimum catchment area to say 2,000m2 is reasonable and provides for some areas that may not
               be efficiently drained to the rainwater harvesting catchment. In any event, a smaller catchment is
               consistent with the lower volume of water proposed to be stored in the preceding subclause.

               Applicant’s request:

               Please replace 135,000 litres with 54,000 litres consistent with the amended pool design having
               a substantially reduced surface area.

               Amend the reference in the subclause of ‘2,800m2 ’ to ‘2,000m2 ’

               Assessment of Representation

               The condition was applied as part of the consideration of the original 106 room hotel and was not
               amended when the development was scaled back to 69 bedrooms. It is acknowledged that a
               reduction in the stormwater harvesting requirements to reflect the reduced building and swimming
               pool footprints is appropriate. Accordingly, it is agreed to amend the condition as requested by the
               applicant.
