1 Introduction
1.1 Background
Taylor Environmental (Australia) Pty Ltd was engaged to design a new on-site wastewater treatment
and effluent disposal system for the tiny home installed at 328 Upper Pinbarren Creek Road, Pinbarren
Qld 4568.
This property is not serviced by a municipal sewer network and requires all wastewater to be managed
on site. The purpose of this report is to design a domestic wastewater management system that meets
the requirements of AS1547 and the Queensland Plumbing and Wastewater Code.
1.2 Proposal
The tiny home, on a trailer next to the dams, has a composting toilet with leachate drain, with greywater
being disposed to land.

• 100% reserve area to be kept clear of permanent structures
• Deep rip base of beds and spread gypsum at 1kg/m2
• Grass is to be established in the land application area, and mown regularly
• Stormwater should not traverse the land application area. Construct a stormwater diversion
upslope
• General access to the land application area by pedestrians, vehicles and animals is to be
generally excluded
• Install at least 2x ‘effluent reuse’ warning signs around land application area
• The system is to be installed, operated and serviced in accordance with manufacture
specifications
• The land application area has been designed based on a daily wastewater volume in accordance
with AS1547. Any exceedance of this design volume may have adverse effects on the land
application area
3
Conservative volume allowance, as composting toilets have very low discharge volumes

4 Maintenance
Property owners have a responsibility to ensure the onsite wastewater treatment and effluent disposal
system is maintained and serviced. The following servicing and precautions are to be undertaken:
• Septic tanks to be checked annually and pumped out when 1/3 full of solids or once every 5
years, whichever is sooner
• Read and follow the Owner's Manual that is provided with the system
• Comply with local authority’s servicing requirements
• Do not manipulate the system so that it no longer complies with the Council issued permit or
the plans located in Appendix A of this document
• Maintain the land application area e.g. regularly mowed and ensure that there is no ponding
of effluent
• Vehicles, animals and general access to the land application area is to be generally restricted
with warning signs erected
• Use low sodium biodegradable soaps and detergents as per the label instructions and no paints,
solvents, chemicals, food scraps, fats, oils or any other solids to be disposed of “down the drain”
• It is always good practice to minimise / stagger high wastewater generating activities such as
laundry over a full week
• On-site sewage systems are not designed to cope with the flow from garbage grinders

TREATMENT PLANT APPROVAL 06/2024
Plumbing and Drainage Regulation 2019, part 4.
Approval
1. The Advanced Enviro-Septic 30 (AES-30) (“the system”) described in the Specifications and
Drawings in the attached Schedule and manufactured by Presby Environmental Inc. Whitefield,
New Hampshire (“the manufacturer”) and supplied by Chankar Environmental Pty Ltd (ACN
148 175 455) (“the supplier”) has been assessed in accordance with:
(a) sections 34 and 35 of the Plumbing and Drainage Regulation 2019 and
(b) the Queensland Plumbing and Wastewater Code published on 26 October 2017.
2. A transitional Treatment plant Approval (TPA) is granted for an advanced secondary quality
wastewater treatment system , subject to compliance by the manufacturer/supplier with the
requirements of the Plumbing and Drainage Act 2018 and the conditions of approval detailed
below.
3. As no changes have been made to the system, this approval replaces the previous approval,
TPA 15/2019 Amendment 2 issued on 20 January 2023.
4. This approval, the conditions of approval, and the Schedule comprise the entire TPA document.
5. Any modification by the manufacturer/supplier to the design, drawings or specifications
scheduled to this approval must be approved by the Chief Executive.
Conditions of approval
6. The manufacture, installation, operation, service, and maintenance of the system must be in
conformity with the conditions of this TPA.
7. The advanced secondary quality wastewater treatment system, which is an example of the
approved systems, may only be used on premises that generate per day:
a) a maximum hydraulic loading of 90 L per 3 m length of AES piping system.
b) a maximum organic loading of 240 mg/L BOD5.
c) a maximum total suspended solids of 300 mg/L.
8. The system must continue to meet the requirements of an advanced secondary quality
wastewater treatment system, producing the following effluent quality —
a) 90% of the samples taken must have a BOD5 less than or equal to 10 g/m³ with no sample
greater than 20 g/m³.
b) 90% of the samples taken must have total suspended solids less than or equal to 10 g/m³
with no sample greater than 20 g/m³.
9. Each system must be serviced in accordance with the details supplied in the owner’s operation
and maintenance manual.
10. The system design is based upon secondary quality effluent design loading rate as defined in
AS/NZ1547 using the Advanced Enviro-Septic (AES) Design Calculator prepared by a qualified
designer. System designs must be verified and signed by the supplier before being submitted to
the Local Government.

Plumbing and Drainage Regulation 2019, part 4.
11. A septic tank conforming to AS/NZ 1546.1 and sized in accordance with AS/NZ 1547 for
treatment of all daily flows of domestic wastewater from the premises is a component of the
system. Effluent 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.
12. Where gravity cannot be achieved to transfer effluent from septic tank to the AES treatment pipes:
(a) A pump well is to be used and sized as per AS/NZ1547:2012 and maintain at least 24-
hour emergency storage above the high-water level alarm sensor.
(b) The pump is to be a submersible type with high level alarm as specified in both
AS1546.3:2017 and AS/NZ 1547:2012. The pump shall be a Davey D25VA or equivalent,
with a design flow of 40 L/min at a minimum 6 m head. Should site conditions require a
higher head, then the appropriate pump model to achieve this shall be selected.
(c) In each situation, the design of the AES system must confirm with the manufacturer’s
design recommendations set out in the AES Calculator & Design and Installation Manual.
13. 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.
14. Each application for a compliance permit to install a system must also be accompanied by a copy
of a completed AES Design Calculator Report endorsed by the supplier, showing the
footprint/basal area of the proposed system and number of pipe modules for the site.
15. 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.
16. 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.
17. 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.
18. Permitted use of the effluent is for sub-surface absorption only.
19. Each system must be supplied with —
(a) a copy of this Treatment Plant Approval document;
(b) details of the system;
(c) instructions for authorised persons for its installation;
(d) a copy of the owner’s manual to be given to the owner at the time of installation; and
(e) detailed instructions for authorised service personal for its operation and maintenance.

20. At each anniversary of the TPA date, the supplier must submit to the Chief Executive a list of all
systems installed in Queensland during the previous 12 months. Where the Chief Executive is
notified of any system failures the Chief Executive may randomly select several installed systems
for audit. The Chief Executive will notify the supplier’s nominated NATA accredited laboratory
which systems are to be audited for BOD5 and TSS. The sampling and testing of the selected
systems, if required, is to be done at the supplier’s expense. The following results must be
reported to the Chief Executive:
a) Address of premises;
b) Date inspected and sampled;
c) Sample identification number;
d) BOD5 for influent and effluent; and
e) TSS for influent and effluent.
21. The Chief Executive may, by written notice, cancel this approval if the manufacturer/supplier fails
—
a) to comply with one or more of the conditions of approval; or
b) within 30 days, to remedy a breach, for which a written notice been given by the Chief
Executive.
22. This approval may only be assigned with the prior written consent of the Chief Executive.
23. Where there is any inconsistency between the content of this approval and the Plumbing and
Drainage Act 2018 (including any associated regulation and/or codes), the provisions of the
Plumbing and Drainage Act 2018 will apply and must be adhered to.
