Appendix G - Geotechnical Report

Limitations of Report & Notes

This report is based on information gathered from the field investigation and information provided by the
client if any. Ground Drill should be notified immediately if ground conditions are found to differ from this
report.

Unless otherwise stated this report does not address the following issues;

    •   Mining Subsidence.
    •   Slope Stability (If the site is in a known slip area or is steep, it is recommended that a Geotechnical
        Engineer be engaged to conduct a Slope Stability assessment).
    •   Deep soft or settling soils
    •   Soil Contamination, hazardous materials and or acid sulphate.
    •   Any slopes, dimensions, levels, site features or plans in this report are approximate only show
        approximate testing locations.
    •   Flood levels (It is the client’s responsibility to inform us of any flood levels on the allotment).
    •   If water is found in the boreholes this depth may vary greatly over time. This report does not address
        the influence any natural springs may have on the structure.
    •   It is the client’s responsibility to inform us of any nearby underground services that have been or will
        be installed near the proposed area.
    •   Earthworks could affect the design.
    •   If any fill is placed on the allotment post investigation this could change the design.
    •   Surface water is to be diverted away from the area.
    •   This investigation undertaken consisted of the occluded boreholes/test pits, given the size of the site
        it is possible that a problem could have been missed. eg. Filled dam/gully, soft soils, fill, springs,
        boulders, rock etc. We cannot give a definitive assurance that none of these problems exist on the site
        unless we did a greater number of boreholes which would be uneconomical and impractical.


                                    Maintenance and Operation of System
    •    Scrape all dishes to remove fats, grease, etc. before washing
    •    Don't use a garbage grinder
    •    Use biodegradable soaps
    •    Use a low-phosphorus detergent
    •    Don't use powerful bleaches
    •    Don't put sanitary napkins and other hygiene products into the system
    •    Spray or irrigation areas should have access restricted
    •    Divert surface water away from land application area
    •    No vehicles or stock should be allowed on trenches, beds or irrigation area.
    •    Deep rooting trees or shrubs should not be grown over absorption trenches or pipes
    •    Vegetable gardens and/or fruit trees should not be planted within or near area, where there is a
         possibility of airborne spray coming into contact with the plant.
    •    Structures should not be constructed near areas that encourage people to congregate.
    •    Play areas and equipment should be well away from areas where there is no possibility of spray
         coming into contact with humans.
    •    Treatment plants and septic tanks are to be desludged every 3-5 years.
    •    Ground Drill will not be liable for any Council Inspection, submission or reviewing fees due to
         changes in report or plan requested by client or Council.
    •    If any part of this design is unclear, please call before buying products or installing.
    •    This report must be approved by the local authority and appropriate permits issued before any works
         can be undertaken.
    •    Installer is to contact Noosa Shire Council prior to burying the system for a site inspection and
         certification.
    •    Follow the manufacturer's instructions, relevant codes, standards and guidelines for installation,
         servicing, maintaining and cleaning the system and irrigation area/trenches/beds
