How Our Septic Tank System Works

To the staff of A&A Worm Farm Waste Systems


Thank you all for your care and professionalism concerning our urgent septic tank system installation.  Initially we had decided on another septic system however after being treated appallingly by the contractor we felt we had no choice but to look for a last minute alternative.  After a recommendation from a neighbour we approached A&A Worm Farm Waste Systems.

In part all the staff of A&A Worm Farm Waste Systems have been friendly, courteous, highly professional and always helpful and we have no reservations about recommending your company to potential clients.

About Our Septic Tank Systems

Our septic tank systems are Australia’s No 1 truly organic septic system and wastewater management system for domestic, commercial and rural applications in Australia today. Other septic tank systems struggle to compare with the benefits and features of the worm farm waste system.

Our highly efficient septic systems allow for the effective conversion of organic waste, sewage and wastewater on site into a reusable liquid fertiliser that is distributed underground throughout your property.

Its a Natural, Biological Septic Tank System that has NO EQUAL.

This powerful organic wastewater treatment system effectively processes sewage, all household wastewater and organic garbage, including food and vegetation, as well as weeds. Combined with naturally occurring organisms, the worm liquid opens up and improves the quality of your soil – enabling you to reuse and recycle it as liquid fertiliser under your garden, lawns and bush land. Independently tested the Worm Farm Waste System is super fast at processing your sewage, wastewater and organic waste. In fact 20 times faster than an normal septic system.

The Eco- Friendly Septic Tank Systems

Not only are you taking responsibility for your sewage and wastewater but your organic waste as well which means you can reduce your disposal of organic garbage to landfill by up to 90%! The system does not have a septic smell and the liquid leaves the system as a clear, odourless and aerated. The worm castings and worm eggs are just what your garden and surrounding bushland need.

Besides domestic sewage treatment systems, we also specialise in domestic, commercial and rural wastewater treatment options. If you need an old system retrofitted we can do that too.

For a custom organic sewage and wastewater treatment system design and installation package to suit your specific site, contact us via email or call +61 3 5979 1887 today.



We have been managing wastewater treatment system installation projects all over Australia from large scale commercial applications to rural and domestic sites. When it comes to Eco-Friendly totally organic sewage and wastewater management solutions, we are No 1!



The natural septic tank system has a huge void capacity for organic garbage, unlike other systems that can only accept very small quantities and generally only through an insinkerator. Years of extensive research and development means that our natural, eco-friendly worm wastewater treatment system offers a simple solution which uses minimal energy for disposing of organic garbage.

All wastewater and sewage is processed and used as an underground liquid fertiliser for your plants, lawns and bush-land. Worm castings from the system are absorbed into the soil combined with processed wastewater to help your trees, shrubs, roses, annuals, lawn and hedges to thrive.

The liquid fertiliser also contains worm eggs which are washed out of the system to hatch and live. The worms then move about scouring and aerating the soil.

The future can be GREEN

With a Worm Farm Waste System



When we first contacted A and A Worm Farm System we received prompt emails, replies and answers. Unlike other worm farm system companies EV and A and A worm farm have been very helpful and thorough from the beginning.

Overall, we are very happy and excited to have our own environmentally friendly worm farm system with no ongoing quarterly maintenance costs.

Lisa and Nigel Spicer

Dutton, SA

The system has worked satisfactorily since installation in July 2002 without any special maintenance. All the waste from the house is treated and remains on the block and provides excellent fertilizer for our vegetable garden. The only liquid leaving the block is storm water. I believe that the system is beneficial to the environment and could be used more widely with great benefit to the environment. I have a strong objection to any waste water being drained into the sea.

Ron McIntyre, Vic

The system has been in place for over 12 months now and the bottom line is that it works. Stuff goes in (an astonishing amount of household organic waste, newspapers, cardboard, garden waste … and, of course, sewerage and grey water) and it seems to cope with ease. The level of the contents of the holding tank appears to stay surprisingly static, so clearly the worms and other organisms are happy.

Plants along the trench line are thriving quite merrily.

Septic Tank Systems That Are GREEN

I bought my first A&A Worm Farm Waste System a few years ago and was so impressed with the service and performance of the system that I purchased a second septic tank system when I built another property last year. Over the years that I have had the Worm Farm Waste System I have found it to be very reliable and flexible. Being able to put other household waste into the system such as kitchen scraps means that our offsite waste has drastically reduced so we add very little to landfill and there are no smelly bins in summer!

Fiona G, Qld

In three years we have had not one incident and why would we, the only moving parts are the worms! This system has been so efficient and caters just as easily when there are only a few people in the house right up to when the masses arrive and settle in for the week.

Rod B, Vic

The worm farm itself is a very nice package, nestled neatly in an inconspicuous corner of the lot, great design and aesthetically pleasing. We will hopefully be building 6-9 small self-contained cottages over the next two years and will most definitely be considering septic tank system for these.

Thanks again for making this a most enjoyable experience.

Cheers, thanks for everything.
