INTRODUCTION
1.1 Purpose of Report
The effluent disposal report was commissioned by Mark Bain and relates to a
proposed sub division at 60 Glenridge Drive, Cooroibah ( Lot 4 RP 860577). The
proposal is to cut this existing land into 8 rural residential lots.
The area is not in a sewered section of this council shire. We will demonstrate that
each allotment will have its own effluent disposal area that complies with the Qld
Plumbing and Wastewater Code.
1.2 Scope of Report
The report addresses issues relating to the on-site treatment and disposal of
wastewater and the potential export of pollutants from the proposed
development. The report assesses the suitability of the site for on-site effluent
disposal and for the management of sewage within the development.

THE SITE and SOIL ASSESMENT
2.1 General
This subdivision is for 8 blocks Lot 1 is 1.532ha with a 1128m² building envelop.
Lot 2 is 1.599ha with a 1100m² building envelop. Lot 3 is 1.660ha with a 1116m²
building envelop. Lot 4 is 1.507ha with a 1100m² building envelop. Lot 5 is
1.502ha with a 1100m² building envelop. Lot 6 is 1.716ha with a 1100m²
building envelop. Lot 7 is 1.509ha with a 1100m² building envelop. Lot 8 is
3.17ha with 1100m² building envelop.
This building envelop with have all dwellings and the effluent disposal tanks and
effluent disposal area in this area.
2.2 Slopes and Drainage
Slope on sites vary. Peakurban has supplied a report on this drainage of
stormwater and have contours, please refer to this report.
2.3 Geology and Soils
No soil test was provided for this report. We have used a Light Clay Category 5
from the 0.6m-1.2m deep. This is a poor drainage soil, the permeability for this
was 3mm/day, a Design Irrigation Rate for irrigation.
2.4 Vegetation
The site has grass as cover and trees.

2.5 Hydraulic Conductivity
The soils on the proposed site are Light Clay with grained sand from
100mm-500mm and a good topsoil.
Conductivities the amount for these soils is approx. 0.06 -0.12m m/d
=10mm/day Design Loading Rate (DLR).
The conclusion is that the results indicate to a preferred Secondary Effluent Type
Treatment System.
SITE ASSESSMENT
3.0 Setback Distances
The Department of Local Government Queensland Plumbing and
Wastewater Code is the guidelines used in preparing this report.
Setback distances area for sub surface irrigation of 2m from a Dwelling.
2m from a boundary if the land is level.
4m from a boundary if the land falls towards that boundary.
10m from a dam, river / drainage gully.

3.1 Flood Potential
Peakurban has supplied a report on this drainage of stormwater and flooding,
please refer to this report.
3.2 Runoff
The dwellings will have roof water to in ground stormwater drainage, to drain to
kerb and channel or to the drainage easement.
Overland flow that will not impact on the effluent disposal area.
3.3 Surface Dampness
The sites are well drained. All house stormwater will be piped to a legal
point of discharge to kerb and channel or to the drainage culvert or piped gully
pits.
3.4 Landform
The recommended disposal sites are not in areas on foot slopes,
drainage plains or incised channels.

EFFLUENT LOADING RATE
4.1 Introduction
For this report we will use a of a four-bedroom house, each dwelling will
discharge to a 4000 litre all purpose septic tank and discharge to 90m² of and
Advanced Enviro-septic disposal area.
ON-SITE DISPOSAL SYSTEM
5.1 Introduction
The on-site sewerage treatment for this site will need to be an Secondary
Treatment Quality.
5.2 Effluent Treatment & Disposal
Using the 4-bedroom model for 6 persons at 150 litre per day will deliver 900
litres per day. This amount of effluent is to discharge to 90m² of effluent disposal
area if the land application area. The new effluent disposal area will be a AES Bed.
This bed will be within the building envelop. with the compliant set back distances
from AS 1547-2012 and stated in section 3 of this report.
Attached in this report is a demonstration of the purpose method and location of
the disposal area.
The AES effluent disposal system can produce Advance Secondary Quality Effluent
with a 10m set back distance from any water course.

5.3 Reserve Area & Wet Weather Storage
Under a domestic situation wet weather is not required, but with this light clay
site it would be a proactive solution to longer period of rain that may cause the
effluent disposal area to fail. This report will be using AES Disposal Bed to be the
method of disposal. A reserve area can be nominated on this allotment, under AS
1547-2012 a reserve area is a duplicated area on this site that the effluent
disposal area can be relocated if the current area falls.
These allotment can accommodate a 100% reserves area if this is implemented.
5.4 Servicing & Maintenance
A contract will be entered into for servicing and maintenance with an
appropriately qualified service agent for regular service.
Thank you for choosing WaterWise Design.

Important Safety instructions
It is extremely dangerous even potentially deadly to open a septic tank,
pumping station or any enclosed space that is part of a wastewater treatment
system. This work must be done by a person trained in enclosed space
working and rescue procedures who has the necessary equipment.
The action of the bacteria on the organic matter present in the wastewater
produces gases such as carbon gas (CO2), methane gas (CH4) and sulphuric
hydrogen (H2S). The H2S present in the septic tank or a pumping station can
cause the death of an individual in a matter of minutes. This is why this work
must be left to competent personnel.
Pipes are buried near your septic installation. Please speak to your contractor
or the technical service of Advanced Enviro-Septic™ in order to take all
the necessary precautions prior to digging or undertaking excavation jobs
near your septic system.
Please be sure that the covers of the septic tank, the pumping station,
and the sampling device are always in place and that they remain accessible
at all times for periodic inspections and interventions when necessary.

Definition of The Enviro-Septic system is composed primarily of two inseparable
the Advanced components: the rows of Advanced Enviro-SepticTM pipe and a layer of
Enviro- system sand.
Septic System
The Enviro-Septic system must be preceded by a septic tank and a wastewater
distribution device. The treated water is drained directly into the soil beneath
the treatment system through a soil absorption system.
What to do if a If in the course of normal use of your septic system you notice any of the
problem following problems:
occurs?
• presence of abnormal odours in the house, around the septic system or
emanating from sources of drinking water,
• abnormally wet soil, presence of persistent puddles or odours in the
area of the septic tank or the Enviro-Septic system,
• slow flushing toilets or other plumbing in the home,
• presence of abnormally abundant vegetation on the surface or around
the septic tank or the Enviro-Septic system installation,
• flooding in the area where the Enviro-Septic system is installed,
• erosion of the land fill on or around the Enviro-Septic system,

system must not be more then what is shown in the table.
The system may also be limited by the capacity of the underlying soil to
permit the infiltration and evacuation of wastewater. This value should be
evaluated by the designer mandated to create the plans and estimates for your
septic installation. It is, therefore, important to verify with the designer if the capacity
of the soil permits complete infiltration and evacuation of the maximum amount of
water able to be treated by the pipes installed.

Functioning of the Enviro-Septic System
The Enviro-Septic system is a passive technology which facilitates the
proliferation of the bacteria responsible for wastewater treatment. It is
comprised mainly of two inseparable components: the rows of Advanced
Enviro-Septic pipes and a layer of system sand.
The Enviro-Septic system must be preceded by a septic tank and a
distribution box (or another method of distribution). It must also be installed
over a polishing leaching field.
Treatment The rows of Advanced Enviro-Septic pipes and system sand permit the
process of the treatment and distribution of wastewater on the surface of the receiving soil
Enviro-Septic (surface of the polishing leaching field).
system
The pipes support, first of all, the separation of particles through flotation and
decantation. The water is then evacuated through perforations situated all
around the pipes and through the pores of the two layers of synthetic media
covering the pipes. These membranes facilitate the fixation of the microbial
cultures which support wastewater treatment as well as longitudinal
distribution.
The layer of sand continues the treatment process and helps in dispersing the
water before it infiltrates into the natural soil. In this way, the Enviro-Septic
system integrates both functions.

Operating the Enviro-Septic System
Initial Use At the time of installation the septic tank must be filled with clear water.
If a pumping station is used, the contractor will verify that it is functioning
properly at the time of installation. The home owner must make sure that
there is adequate electricity to safely operate the equipment as well as the
alarm component.
The Enviro-Septic system is now ready for use.

Enviro-Septic System Operating Instructions
The use and the maintenance of an Enviro-Septic System are relatively
simple. In general, respecting the following rules will allow you use of your
installation without problems for years to come.
Wastewater Large quantities of water that leave the house and enter the Enviro-Septic
Volume System in a short period of time could have a negative impact on the
effectiveness of the treatment and the infiltration of wastewater causing
agitation in the septic tank. A quantity of sludge or scum is likely to be put into
suspension and be brought towards the system and the infiltration bed.
You must ensure that the volume of wastewater entering the Enviro-Septic
System is reasonable when compared to the total daily flow the system was
designed for.
After the installation, if changes are made to the residence (ex. addition of a
bedroom), please contact the designer of the Enviro-Septic System. Make
sure that the septic system is inspected by a qualified person to determine that
it has the necessary capacity to treat and infiltrate the new daily design flow of
wastewater being generated.

Do not :
• use disinfectant in tablet (puck) form, whether it is placed in the basin
or the tank,
• throw cigarettes, cigarette butts or medication in the toilet,
• throw paper towels, paper napkins or other personal hygiene products
in the toilet.
In the kitchen Do:
• repair any leaking faucet,
• use dish soap or dishwasher soap that is low in phosphate (0 to 5%),
• use the necessary quantity of soap to do the work. Take note that the
necessary quantity is often less than suggested by the manufacturer.
• use biodegradeable soap, low-phosphorus or phosphorus free detergents.
Do not :
• use a food waste disposal unit in your sink that is connected to your
septic installation. If you do have a waste disposal unit, your septic tank
may require more frequent pump out to remove sludge build up
• dispose of vegetables, meats, fat, oil, coffee beans, citrus products or
other products into the septic system.
For the laundry Do:
• use phosphate free detergent, preferably in liquid form. If it is not
possible, use biodegradable powder detergent,
• use the necessary quantity of soap to do the work. Take note that the
necessary quantity is often less than that suggested by the manufacturer,
• minimize the volume of water used for the laundry according to the
quantity of clothing to wash,
• if possible spread your loads of laundry throughout the week
• prevent harsh chemicals or products entering the system (eg. paint, nappies)
Elsewhere Do:

• dispose of solvents, paints, antifreeze, engine oil or other chemicals in
the septic installation. This includes water used to wash brushes or
rollers that were used with latex paint (latex paint contains elements
that are harmful to septic system),
• dispose of animal litter in the septic installation.
Chemicals for Your Enviro-Septic System does not require any starting chemical, cleaning
septic or other additives. The bacteria that carry out the treatment are naturally
installation present in raw domestic sewage. Any chemicals or additives added to the
Enviro-Septic System could possibly kill these bacteria.
Ventilation It is very important to ensure that good ventilation occurs so that the septic
system functions correctly. The vent(s) installed at the ends of the septic
system encourage this air circulation. It is important to make sure that the
opening is not blocked and that air can circulate freely at all times. Air enters
through the vent, circulates through the rows of pipes and the septic tank and
travels through the plumbing of the house to exit through the roof vent.
The owner must be sure to have a roof vent and to keep it clear at all times.
When a pumping station is used, a bypass pipe or an extra vent must be used
to ensure proper ventilation of the system.
Heavy No vehicles or heavy machinery must be driven on a septic system, whether
machinery and it is before, during or after its construction. Heavy machinery or motorized
motorized vehicle traffic on the soil closes the natural pores of the soil which reduces its
vehicle traffic permeability and allows for pounding and the accumulation of water.
Vegetation The surface of the Advanced Enviro-septic system must be planted with
grass. The grass must be cut regularly in order to encourage growth without
the use of fertilisers. Vegetation cover contributes to the elimination of
nitrogen and phosphorus.
It is important not to plant trees or other plants with invasive roots within 3
meters of the Advanced Enviro-Septic system installation footprint.

Enviro-Septic System Maintenance
Septic Tank The septic tank preceding the Enviro-Septic System must be pumped out
Maintenance regularly (every 3-5 years for normal residential use or sludge and scum
exceeds 2/3 of the tank). Verify the current regulation, or get in touch with
relevant council or government authorities.
If the septic tank is not emptied regularly, an increasingly large amount of
solids and grease in suspension will leave the septic tank and end up in the
treatment system and in time the performance of the Enviro-Septic System may
be affected.
At all times, a professional using the proper equipment must carry out the
pumping out of a septic tank
The owner is responsible to ensure his septic tank is pumped out according to
council regulations. This work should always be done by a qualified person
since it can be very dangerous to open a septic system without first taking the
necessary precautions.
Note: It is the home owner’s responsibility to make sure that at all times the
septic tank lids are in their proper position and securely fastened. A lid that is
not installed correctly can be harmful to the operation of the Enviro-Septic
System.

A septic tank conforming to AS/NZ 1546.1 and sized in accordance with AS/NZ 1547 for the influent hydraulic load from the dwelling is a pre-requisite. Waste from the septic tank is to be diverted to the AES piping system prior to the system sand and basal area. The septic tank that feeds into the system must be regularly monitored and maintained (including de- sludging) in accordance with AS/NZ 1547 to ensure optimum operation of the system. 4 - When granting a compliance permit, the local government must satisfy itself that the designer's choice of the system configuration is optimal for the proposed use and site conditions and that the effluent can be retained within the land application area. 12. Each application for a compliance permit to install a system must also be accompanied by a copy of a completed Advanced Enviro-Septic Design Calculator Report endorsed by the supplier, showing the footprint/basal area of the proposed system and number of pipe modules for the site. 13. An inspection/sampling point must be installed permanently in the sand immediately below the half-way point of the AES piping system. Where a system is installed in a sloping basal area an additional inspection/sampling point must be installed at the lowest point of the system extension. 14, Each system installation must be inspected and checked by the designer or the designers’ agent. The designer on completion, is to certify that the system has been constructed, installed and commissioned in accordance with its design, the conditions of accreditation and any additional requirements set in the permit. 15, Routine maintenance of the system at set intervals, other than septic tank sludge levels, is not stipulated by the manufacturer/supplier. However, routine monitoring may be required by the Local Government. In the event of failure of the system’s land application area an AES authorised person may need to follow the rejuvenation procedures set out in the manufacturer/supplier’s Design and Installation Manual. 16. Where a system installed at a site, has been found not to operate satisfactorily during its service life, and as a result requires modification to achieve the required performance requirements, in particular, water quality limits, the installed system is to be modified accordingly. Any modifications including any of the supplier's rejuvenation procedure outcomes must be recorded on the service report. 17. Permitted use of the effluent is for sub-surface absorption only. 1 > .
