                  design and siting of effluent disposal systems.

  (2)   This policy applies to development that is:
        (a)       outside of sewerage service areas; and
        (b)       a material change of use or reconfiguring of a lot.


 SC6.11.2              Design

 (1)    An on­site effluent system is installed that:
        (a)   is designed, approved and installed by a licensed plumber or drainer or other person who has been accredited by the State
              Government; and
        (b)   is calculated assuming waste water flows for standard water fittings.

 (2)    If the effluent disposal system uses surface irrigation, it has permanently installed pipework that evenly distributes effluent.
 (3)    Systems using holding tanks and requiring a regulated pump­out service have a storage capacity of not less than seven days
        peak demand.


 SC6.11.3              Siting

 (1)    The effluent disposal system is located on land:
        (a)   at least 15 metres from any potable water supply tank;
        (b)   above the 1% AEP (1:100 ARI) flood level; and
        (c)   more than 40 metres horizontally from the level of the Highest Astronomical Tide (HAT);

 (2)    Within the Water Supply Buffer Area as shown on the Water Resources and Gas Pipeline Overlay:
        (a)   no on site effluent treatment and disposal system is located within the 90­day detention zone (see Figure SC6.11.1); or
        (b)   outside the 90­day detention zone but within 400 metres of the full level of Lake Macdonald (see Figure SC6.11.1), the
              disposal area (land application area) for any on site effluent treatment and disposal system must be located to achieve the
              greatest possible setback, but not less than 100 metres from any permanent or intermittent watercourse; or
