STORMWATER MANAGEMENT 42
4.5.6 Wastewater System BMP’s
For sites that are unable to be connected to a reticulated sewerage system, careful design,
construction and operation of wastewater treatment and disposal systems is recommended.
Rather than ‘automatic’ adoption of a septic system, consideration should be given to
innovative wastewater disposal and reuse option such as:
• on site wastewater treatment (eg. Biocycle units) with storage and irrigation and discharge
to infiltration areas only under wet weather conditions;
• grey water treatment and reuse;
• mounding and transpiration systems; and
• composting toilets.
4.5.7 Wetlands and Detention Basins
The use of major structural measures such as wetlands, lakes and detention basins to manage
stormwater is not considered relevant to the SLVA due to the local land form and the
environmental significance and heavily vegetated nature of waterways in the area. For those
portions of the larger SLA however, there may be potential for the application of such measures
within more sparsely vegetated or cleared land draining to Wallis Lake via Duck and Wallis
Creeks.
4.6 Stormwater Management Requirements
Previous sections have presented a ‘suite’ of planning and management practices which, when
appropriately combined, will enable sustainable development in the SLA and SLVA area.
Table 4.1 below provides Council with appropriate recommendations with respect to how these
separate planning and management practices could be combined for each of the areas of
sensitivity of receiving water quality protection identified in Section 7.
