AES Advanced Enviro-Septic Australia for Designers

Advanced Enviro Septic


Conventional Septic Systems have been the most common on-site effluent disposal systems in Australia with the 1st system installed in Adelaide in 1906. It is still recognised as the simplest and most cost effective option with the exception of its Achilles heel being progressive failure. (The blocking of the receiving soil with suspended solids and dead biomat.)

During the 90s the 1st AWTS system was introduced. The perception that the engineering of a complicated mechanical system would improve the community health and environmental outcomes is now the subject of increasing industry debate with numerous studies finding failure rates of 95%. (Read More)

As a designer of land application areas the importance of your role in engineering and guiding your clients provides the opportunity for a long term, low cost and high quality community health and environmental outcome. Over 100yrs of knowledge is applied in AS1547 and it is time to bring the SEPTIC BACK as the best option in all soil types with land application design practice and Advanced Enviro-septic.

  • The AES on-site treatment process uses a natural bacterial process to remove 99% of wastewater contaminants and ensure a potential system life of over 20 yrs. Watch the video
  • Achieves Advanced Secondary quality water with no electricity or harmful chemicals
  • Approved and used in more Countries and National Parks than any other system in Australia
  • Made with significant quantities of recycled plastic with the components guaranteed for 20yrs.
  • Provide greater protection of soil and ground water.
  • Durable, non-biodegradable components that last indefinitely with a 20-year guarantee against manufacturing defects.
  • Bacteria destroys 99% of all contaminants before it contacts the soil ensuring no replacement costs
  • Requires no servicing other than pump out of your septic tank depending on the amount of sludge build up. MostCouncils and AS 1547-2012 recommend every 3 to 5 years.
  • No expensive pumps, blowers or computer control boards are required. (Most of these items have a limited warranty of 12 months and when they fail you can be confronted with costs of up to $1000.00 to supply and replace a control board for example.)
  • NO ELECTRICTY costs. (Rotorua Council testing had AWTS systems that used $800 worth of Electricity per year.)
  • AES is installed by licenced plumbers, which have completed the free AES certification course, allowing you to obtain several quotes ensuring you are getting the best value for your money and do not require you to sign long term maintenance agreements.
  • Cheaper than an AWTS and no more expensive than a conventional septic to install.
  • Uses course sand instead of crushed rock, which is much easier to work with and to get into difficult places.
  • AES does not fail if you take a holiday or you have a power failure or accidentally turn the power off.
  • Designers can complete the free basic AES certification course on-line. Get certified
  • Can be used for new and retrofit applications. Retro fit applications where septic tanks are separate from the grey water, then classification of the water quality must be secondary as all testing for Advanced Secondary has been conducted with all waste through the septic tank.
  • Design criteria from Site and soil report entered into AES calculator provides checking data for Chankar Environmental and forms part of Councils Approval application. Enter site address and all other relevant information including daily design load, soil classification etc.The completed AES calculator is then emailed to our office. We check the AES design and assist designers in realising the best AES outcome for both you the designer and your client. The approved calculator is then digitally signed and returned to the designer for application to the Local Authority. (Please Note that an unsigned calculator could delay the application and result in a RFI (request for further information.)
  • The calculator will generate a bill of AES components required for the system. When a quote is required by an AES certified Plumber, they simply submit the approved calculator and our staff will assist with supply and delivery.



  • Good design methods allow the AES to be used in all classifications of soil types as listed belowUp to Cat 6 – site and soil conditions dictate the AES design
  • Level sites – heavy soil, high rain fall
  • Sloping sites
  • Steep sloping
  • Contour trench
  • Lineal Loading
  • Small footprints can be achieved per AS1547:2012 by the using the Secondary DLR loading rates.
  • Reduced set backs are available in Queensland due to Advanced Secondary standard achieved by the AES.
  • AES pipes are flexible and allow trench’s to be installed along the contours of the site and to create curved beds around site constraints such as building etc.
  • AES achieves even distribution of treated water over the full length of the AES pipe.
  • AES can be designed for systems from 180litres per day to unlimited 300,000 +.
  • AES can be installed under car parks and driveways to save space in sensitive environmental areas or restricted sites such as motels etc. refer to H20 Report Click here to view h20 report.
  • Advanced AES system designs including multi-layer, capture and reuse can be achieved. Designs of this nature will have a much higher level of assistance from Chankar Environmental to ensure the best possible outcome.
    AES system sand is a course clean sand with less than 2% silt content. Course sand used in the manufacture of concrete will always meet this spec. We provide a free testing service using the Presby Spec checker.For more information select this system sand link.
