Stormwater for domestic buildings
       The roof of every domestic building shall be provided with a complete and effective
        drainage system to the satisfaction of the building certifier, which must ultimately comply
        with the requirements of the Building Code of Australia.

       The stormwater drainage must discharge to the kerb and channel (road frontage) where
        a kerb adaptor has been provided by the developer at the time of the original subdivision;
        or if the minimum pipe grade of 1:100 is achievable and adequate cover over that pipe
        can be obtained. In this instance, the pipe shall be connected to the kerbing with an
        approved galvanized mild steel kerb adaptor. The kerbing shall be “neatly” cut so the
        kerb adaptor can be grouted into position and once in position it does not change the
        profile of the kerbing.

       Where there is an inter-allotment drainage network provided with an approved
        connection point to receive the property’s stormwater drainage system then it must
        discharge to that drainage network.

       If there is no inter-allotment drainage network and the private stormwater drainage
        system falls away from the street it must be discharged to an on-site stormwater
        dispersion system.

       An on-site dispersion system (rubble pit) must be placed so that it does not cause
        stormwater to pond under the floor of any building; or to flood around the foundations of
        any building; or cause nuisance to neighbouring properties.
