8 Maintenance
Homeowners 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

c) a maximum total suspended solids of 300mg/L.
9. The system must continue to meet the requirements of 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 10g/m³ with no sample greater than 20g/m³.
10. Each system must be serviced in accordance with the details supplied in the owner’s
operation and maintenance manual.

11. The system design is based upon secondary quality effluent design loading rate as
defined in AS/NZ1547 using the 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.
12. 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 component of the system. 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.
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 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.
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 Treatment Plant Approval 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 a number of 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. This approval expires on 1 January 2024 unless cancelled earlier in accordance with
paragraph 21 above.
