Att13 - Hydraulic and Wet Fire Services Investigation

                                                                        CYC Noosa Campsite

2           SITE INFRASTRUCTURE
2.1         On-Site Sewage and Land Application.
The Sewage Treatment Facility and land application area for this development will exceed 20EP and
therefore constitutes an ERA63. It’s understood that a Future Plus have been engaged to conduct a
Land Suitability Report in preparation for a future ERA application.

2.2         Wet Fire Services
For Class 2 to 9 buildings over 500m2 we will need hydrant protection in accordance with BCA2019
Part E1.3. Therefore,
     •    A H-pattern booster facility at the entrance to the site. Preferably adjacent the carpark
          adjacent hardstand.
     •    288,000 litres of water storage (2 x 144 KL tanks) above ground and near the H-pattern
          Booster Assembly
     •    Two diesel fire hydrant pumps
     •    All weather vehicular access for a Fire Appliance to any external attack hydrant protecting
          class 2 to 9 buildings over 500m2

2.3         Water Supply Options
Three potential water sources exist on-site.
     •    Rainwater collected on proposed building roof areas.
     •    Dam water available from the abundant 100 Acre dam.
     •    Bore Water (yet untested for water flow and quality).

DRINKING WATER
CYC have expressed a preference for rainwater harvesting and reuse for potable reuse purposes. MRP
have reviewed the proposed roof area, the mean decile 5 rainfall for the nearest BOM weather station
(Tewantin RSL) and the number of patrons likely to be onsite to determine if Rainwater alone will supply
the anticipated demand.

The following high-level criteria have informed our preliminary analysis.


     •    Daily water demand per person: 130 l/day
     •    100% occupancy / 7 days per week.
     •    1 million litres of rainwater storage
     •    Village of 140 occupants: Roof Area: 2,350m2
     •    Village of 100 occupants: Roof Area 2,020m2
     •    Village of 60 occupants: 1,600m2


Table 1 below representing average rainwater inflow and reuse based on the above-mentioned input
criteria. This table indicating the need for monthly town water (tank top-up) contributions each month.
In the absence of reticulated town water, this shortfall would need to be made up by alternate means.
