  The hydraulic loading for the proposed development has been estimated using Table H4 of AS1547:2012.
  This Guideline provides the most accurate assessment for flow rates from a campsite like this, and is
  based on the use of on-site roof water and dam water as the primary potable water sources.

  Indicative hydraulic loading based on this Guideline and type of the development activity has been
  adopted to calculate the average daily sewage flows resulting from the proposed development and is
  detailed in Table 4 below:

  Table 4: Calculated Hydraulic Wastewater Flows

                                     Sewage Flows per Table                              Equivalent
                      Proposed                                     Total Sewage
         Type                           H4 – AS1547:2012                              Population (EP) -
                      Population                                   Flows (L/day)
                                          (L/day/person)                                    200L

       Campers             300                 100                       30,000             150

     Staff Members         20                  100                        2,000              10

        Total Daily Sewage Flows and Equivalent Population             32,000 L/day         160



  Table 4 above shows that a total daily sewage flow calculated for the project of 32,000 L/day (160
  Equivalent Persons) will be generated as a result of the proposed development.

          APPROVAL PROCESS

  Based on the estimated hydraulic loading calculated in Section 3.3 above, the proposed development will
  trigger the need to obtain an Environmentally Relevant Activity (ERA 63) approval from Department of
  Environment and Science due to the sites daily wastewater loading exceeding 21 equivariant persons.
  The ERA 63 application will be undertaken during the Building Approval (BA) phase of the development.

          TREATMENT SYSTEM

  Treatment of wastewater to a minimum of advanced secondary effluent quality in accordance with the
  Queensland Plumbing and Wastewater Code may be achieved by the installation of either an aerobic
  wastewater treatment system or biological sand filtration system.

          ADDITIONAL DESIGN CONSIDERATIONS

  A number of other design considerations should be made in relation to the following key elements
  associated with this type of development.
