DOMESTIC WASTE WATER LAND APPLICATION DESIGN
Designer Name: CSI Soil Testing
QBCC Licence Number: QBCC Site Classifiers Lic No. 1064963
AES Certificate Number: 202

1. Site conditions:
The area is grassed with scattered trees. The general area slopes at approximately 3-10%.

2. Soil Assessment:
The bore logs of the site indicate that the soil profile consists of a dark grey CLAY over grey CLAY over yellow brown
mottled light grey CLAY over red brown CLAY. From on-site visual examination a textural classification of Category 5
has been adopted.

3. Calculation of Disposal Area using the AES Design Calculator.
Direct Natural Ground: AES pipes bedded in coarse washed sand
Excavated Bed Dimensions: 9.6 long x 12.5m wide, (from AES Infiltration Foot Print Area minimum footprint) 900mm
deep (depth is AES system sand depth from AES dimensions table + 150mm backfill). Total footprint area = 120 m2

        If standard fixtures used:
        CAT 5 SOIL
        TOWN WATER
        8 PEOPLE
        150 litres/day/person (Reticulated/Bore)
        Q (day) = 8x150 = 1200 litres/day
        DLR = 10 mm/day
        REQUIRED BED = 9.6 long x 12.5m wide, 900mm deep AES beds.

5. Land Application Method and Area:
•   The bed shall be mounded and cut into natural ground only enough to create a toe in natural ground
•   It is proposed that disposal be by 300mm AES pipes layed in a bed of washed coarse sand.
•   Installation to be to AES Design and Installation standards by a suitably experienced, qualified and licenced
    plumber/drainer.
•   The bed will be a minimum of 9.6 long x 2.7m wide with an additional 9.8m system extension due to high category
    soils. The AES bed will be 900mm deep which will include 300mm system sand below the pipes, 150mm system
    sand above the pipes and 150mm topsoil above that sand. The system sand extension shall be downhill of the main
    bed and be a minimum 150mm deep by the length of the bed by 9.8m wide and located at the bottom of the bed
    depth.
•   An inspection port is required to be installed at the furthest point from the influent to AES pipe.
•   Plan to excavate in dry times if possible.
•   Strip topsoils for use later as topsoil over AES system.
•   Ensure that the natural soil is not compacted or smoothed over while excavating and installing and that clay soils
    are scarified 200mm deep. Gypsum may be added to clay.
•   Diversion drains/mounds will be required to intercept any surface waters draining onto and from the disposal area.
•   A Primary Septic system complying to AS1546.1 2008, with a pump well, is to be used.
•   The Land Application area shall be grassed. Native shrubs (with non-intrusive roots suitable for the local area and
    for being adjacent to effluent disposal areas – see horticulturist for advice) should be planted at the downhill edge of
    the land application area. Access for future maintenance should be considered.
•   The land application area shall be in the vicinity of Test holes (TH).
•   The area shall maintain a distance of 10m away from the watercourses.
•   This report has been compiled using information supplied by the owner i.e. 5 (five) equivalent bedrooms. If
    information has changed this report will become void and may not be used and will need to be amended (further
    charges will apply).

6. Waste water system Installation:

•   Installation shall be carried out by suitably qualified persons (licensed Drainer) following the AES
    suppliers/manufacturers guidelines/specifications and any relevant standards/ Local Authority conditions and must
    at all times adhere to industry best practice. Installation must comply with AS/NZS 3500, Plumbing and Drainage
    Act, AS/NZS 1547 and the On-site sewerage code. Other Federal, State and local laws or referenced standards
    may be relevant.
•   The use of water saving devices is recommended.
•   The location of the septic tank shall meet council requirements and shall be downhill from the building and above
    the flood and storm water flows.
•   All Council approvals must be obtained prior to commencement of work.
•   Design detail, logistics and proper functioning of the plumbing works is the responsibility of the installation
    plumber/drainers.
•   The designated land application area shall be clearly delineated with vegetation or other type of border.
•   At least two (2) warning signs shall be erected on the boundaries of the land application area eg. ‘WARNING-KEEP
    OUT- EFFLUENT’
•   Prior to engagement, the installation will be required to be inspected. As registered Site and Soil
    Evaluators/Designers we can issue you with a site inspection certificate to acknowledge installation is according to
    our design (further charges apply). The installer must be a licensed Drainer and must certify the installation.

Please ensure that the building design engineer sees this report so they can be aware of the introduction of water to the
soils in the land application area, in case it affects the footing design.

7. Maintenance requirements:

•   The owner/tenant shall comply with the manufacturer and suppliers, maintenance and best practice requirements
    (supplied at installation) to ensure the proper functioning of the system. These procedures should be passed onto
    subsequent owners/tenants.
•   The owner should ensure that the system is inspected for performance by a suitably qualified service technician
    according to system and/or Council requirements.
•   The designated land application area shall be kept clear of all humans, animals and traffic.
•   The use of strong caustic, alkalis, oils, acids, bleaches, disinfectants or chemical detergents may kill the essential
    bacteria, and harm the natural break down process both in the tank and in the pipes.
