              3.4      Setback Distances
              The Queensland Plumbing and Wastewater Code V1:2024 Appendix 1 outlines minimum setback
              separation distances required for on-site wastewater management facilities. This design complies with
              the relevant setbacks.

              The ‘Land Application Area Setback Distances’ (QPWC Table T2) are presented in Table 6.

              *Distances are given in meters and are measured from the edge of trench/bed excavation or subsurface irrigation distribution
              pipework to the nearest point of the feature

              The ‘Protection of Surface Water and Groundwater Setback Distances’ (QPWC Table T5) are presented
              in Table 7.

              Where ‘on-site sewage facility’ is defined as:
                       a facility, other than an environmentally relevant on-site sewage facility, installed on premises, that includes:
                                   (i) an on-site sewage treatment plant on the premises for treating sewage produced on the premises; and
                                   (ii) either
                                               a. a land application area on the premises for disposal of the effluent produced by the on-site
                                               sewage treatment plant; or
                                               b. a tank for storing on the premises the effluent produced by the on-site sewage treatment plant
                                               for later disposal off the premises by collection from the tank; or

              The sewage pump stations are not formal parts of the ‘on-site sewage facility’.
