Appendix D - Effluent Disposal System

                                                                                                  QBCC: 15336345 ABN: 35 622 809 376




    PLANTING REGIME
    No plantings to be within 3m of the trench / beds. However, further qualified advice from local
    nurserymen and the local regulatory authority should be preferred when choosing plants so as not to have
    any root invasion of the system.
    A good grass cover over the trench / bed System is required to improve the efficiency of the system with
    the uptake of nutrient and natural transpiration processes. Grasses should be kept well mown and raked
    for better evaporative and transpiration processes (avoid throwing grass clippings onto the Land
    Application Area). Shrubs should be kept well pruned for better evaporative and transpiration processes.
    Do not plant shrubs or trees within the surface water diversion drains, as these drains need to be kept free
    of obstruction and trash for maximum diversion efficiency.
    Depending on the dose loading of the system future planting may need to be placed to the low side of the
    land application facility.


    SEPARATION DISTANCE REQUIREMENTS
    One of the most important parameters to consider in the location of Land Application Areas is the
    separation distances, both vertical and horizontal (Queensland Plumbing and Wastewater Code). Poorly or
    inappropriately selected ground may contribute to the pollution of surface water and groundwater,
    ponding and eutrophication.
