SC6.11­          PSP10 Effluent disposal
SC6.11.1          Purpose

(1)   The purpose of the Effluent disposal planning policy is to:
      (a)    ensure that where development is not served by reticulated sewage infrastructure, there is no adverse impact on ground
             and surface water quality, human health and amenity as a consequence of the on­site disposal of effluent;
      (b)    ensure that land use decisions favour the protection of ground and surface water quality where there is doubt regarding
             the likely impacts of on­site disposal of effluent; and
      (c)    provide guidance to the public, developers and Council staff to assist in assessing development applications in relating to
             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
