                                              Disposal method                Trenches with Ø100 slotted pipe
                     Disposal Area            Required disposal area         A = Q/DLR = 60 m2 + equivalent reserve area
                                              Install as                     6 trenches x (0.6m wide x 17m long) = 61 m2

              The design of the system is presented in Appendix A.
              The Treatment Plant Approval is presented in Appendix B.

              General requirements and notes
                 • Flow meter to be installed on pump main between OSSF and LAA
                 • 100% reserve area to be kept clear of permanent structures
                 • Deep rip base of trenches and spread gypsum at 1kg/m2
                 • Grass is to be established in the land application area, and mown regularly
                 • Stormwater should not traverse the land application area. Construct a stormwater diversion
                      upslope
                 • General access to the land application area by pedestrians, vehicles and animals is to be
                      generally excluded
                 • Install at least 2x ‘effluent reuse’ warning signs around land application area
                 • The treatment plant is to be installed, operated and serviced in accordance with manufacture
                      specifications
                 • The land application area has been designed based on a daily wastewater volume in accordance
                      with AS1547. Any exceedance of this design volume may have adverse effects on the land
                      application area
