AES is the ideal residential on-site secondary wastewater system removing up to 99% of wastewater impurities without the need for electricity or replacement media. Most other systems require a pump to discharge, but not the standard AES system. It can be installed for new houses or retrofitted to an existing system that is no longer functioning well or needs to service higher occupancy levels. It easily handles intermittent use in holiday homes. Existing infrastructure components – for example septic tanks – can often be reused when upgrading to an AES wastewater treatment system.

AES wastewater treatment system - a passive system

A Passive System
AES passively creates a powerful biological ecosystem that continually digests organic matter in wastewater. It achieves excellent pathogen reduction in an aerated environment, without using UV filters or chlorination, pumps or alarms. Patented unique features of the system like the Bio-Accelerator® fabric in the pipes speeds the development of the biomat where treatment occurs.

AES Wastewater treatment - a reliable system

A Reliable System
AES components have a 20 year warranty and are expected to last indefinitely. Risks arising from mechanical or electrical failure are not present in the standard AES system.  The system keeps on working without servicing or intervention even when there is intermittent usage and variable wastewater loads.

AES Wastewater Treatment - a global system

A Leading Global System
The AES wastewater treatment system is a leading treatment system in the USA, Canada, Europe, Australia and many countries worldwide.
Tested in labs throughout the world, it consistently achieves very high treatment results.
It is manufactured to the highest standards in the USA.

AES wastewater treatment - Greywater Recycling

Greywater Recycling
Discharge via dripper lines from an AES lined bed system is frequently the most cost-effective way to reuse all your treated wastewater for irrigation. Greywater is usually considered to be waste flows from basins, showers and laundry. If you already have a wastewater system, the Aqua2use greywater recycling unit, also supplied by Environment Technology, is easily retro‐fitted to existing wastewater systems or incorporated into new designs.

Your House

Contact us to discuss your project.

We will be with you all the way through the process of design, consent and installation and provide contacts for AES certified designers and installers.

An AES certified designer near you will prepare a wastewater design report for submission to council for consent approval.

An AES certified installer in your area orders the system components from us and completes the installation of the wastewater system. Your plumber/drainlayer may be certified to design AES systems or can become certified by doing our free online course.

A Typical Three-Four Bedroom house

An AES wastewater treatment system for a 3-4 bedroom house (eg 5-8 people) would normally consist of 2 rows of 3m long, 300mm diameter AES pipes (8-11 pipes in total) in a sand bed. Your wastewater designer will also include factors such as soil type, groundwater depth, water source, water-saving devices, etc., to determine the system size for your house.

Effluent gravity flows from the septic tank into the first row of pipes. Whenever effluent rises 2/3 up the height of the pipe, it will flow into the second pipe row. The two rows are aerated by the chimney effect of a high vent at one end and a low vent at the other. The high vent is often camouflaged against the house or a shed.

The pipes are installed in a sand bed with a top layer of soil so the whole system can be landscaped with shallow rooting plants becoming part of the garden. This bed can also be placed beneath a driveway if space is limited, or could be in a curved formation to fit on site.

If your site is near a water source or has high groundwater, your AES system can be installed in a raised bed which can be aesthetically planted to blend into the landscape.

If your soil type is dense (e.g. heavy clay), your AES system can be installed in a lined bed. A lined bed can also be used to collect treated effluent for irrigation.

Retrofit to Upgrade an Existing System

AES is a great solution for refitting a failing or non-compliant wastewater system at a bach, crib or holiday home. Councils often require an upgrade from a septic tank and soakage trench to a secondary treatment system. An AES system:

  • Works well with intermittent use and shock loads
  • Has no alarms to go off or pumps to fail
  • Requires very little maintenance
  • Can incorporate an existing septic tank in a new design
  • Treats effluent to advanced secondary level

Holiday homes are also often located near a water source or have high groundwater levels. The AES system can be installed in a raised bed under these conditions. AES can also be fitted into a small site by installation under a driveway or parking area, or curved around the landscaping. Section planting helps reduce subsurface loading.
