Appreciate all the help and the professional advice Allan could provide on where it is best suited etc. He was great to deal with and I look forward to seeing the system in action. Will happily recommend the service so far that’s for sure.

Hi Liz

The installation couldn’t have gone smoother. Tony was extremely competent and professional and is a great asset to your business. We will pay the balance by direct deposit in the next day or so. Please pass along to Tony our thanks for a worry free experience.



Sean O’Grady


Thank you Liz

We were very impressed with Tony. He worked hard and put in long days, he didn’t grizzle about the rain or the mud, and left our site very clean and tidy.

Tony was an incredible worker who had to endure working in massive, unseasonal downpours, hail, and huge winds over the three days – not to mention the ridiculously rocky site he had to dig into!.  He was amazing and I can’t believe the amount of work he managed to achieve under those conditions.  He just kept soldiering on and never gave in!  I really can’t believe how calm and professional he remained when confronted with each obstacle (and there were quite a few!) – he took it all in his stride and just did what had to be done to get the task completed.  Amazing.


Thanks again

Kind regards

Liz Butler

Thank you! Thank you! Thank you!


We are hugely impressed with the professional installation of our worm system and with Tony’s polite manner and extra care.

Our neighbours have a worm system which they continue to express how clean and easy they run.

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 has 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.

To the staff of A&A Worm Farm Waste Systems


Thank you all for your care and professionalism concerning our urgent sewage treatment plant installation.  Initially we had decided on a 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.


From the outset we were treated like friends rather than customers.  We received a detailed quote within hours and soon accepted the quote.  The entire system was installed within 7 days of acceptance by a highly professional in house team who gave great advice on use and maintenance and answered all our questions.  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.

Highly recommended

In regards to the installation I was most impressed with Anthony and his professionalism and knowledge regarding the overall job.  I extended my gratitude to him for his work but would appreciate if you could also pass on our thanks on a job well done.  Also we have been managing various sub contractors for our build and have found your company to be one of the most professional to deal with, being very organised with timelines and information.

Your communication has been excellent and will highly recommend your services going forward to anyone considering installing a similar system.


Thanks again

Almost two years ago, we began building a new house on a bare cow paddock in the hills above Foster in Sth Gippsland. Our distance from many services meant that we had to come up with a self-contained management system for water collection and sewerage/grey water treatment. Water collection is an easy one to solve, but the latter problem allows for a more creative or innovative solution.


After reading a great deal and talking to anyone who’d listen, I came across an ad for Worm Farm Waste Systems in ReNew magazine. It sounded good, so I spoke to Alan and Ev Duke about the mechanics of the system and the logistics of installation. I then spoke to the Health Officer at the Sth Gippsland Shire Council, Callum Morrison, who surprised me with his enthusiasm for both the product and for my preparedness to explore a less conventional solution. Armed with great advice and support, plus the knowledge that the project made sense economically, we went ahead.


Two things made the project much easier than I imagined it would be … the company’s eagerness to answer any stupid question I came up with AND the fact that they made no fuss about installing on a block that is 2 hours from Melbourne and in very hilly terrain. The permit application was handled seamlessly and independently of us, and Callum Morrison from the Sth Gippsland Shire collaborated with advice, as well as his preference for siting both the tank and the trenches … and then the project went ahead.


The installation all happened in our absence, so I didn’t get to witness any mess or chaos. However, when we DID see things afterwards, we were thrilled at the apparent effortlessness of it all. The location was good and the attendant plumbing, ready to attach to the house, was well placed with access to all parts well marked, but also well out of the way. All the earthworks were neat and exactly where we wanted them. And, in addition, Alan had kindly dug another trench and fitted an overflow pipe on our new water tank. The latter was not in the contract, but I am forever grateful to him for such a thoughtful act.


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. We’ve planted a lot of plants that like a fair amount of moisture along the trench line and they are thriving quite merrily.


So we’re extremely happy with the system and I have no doubt now that the system will keep doing what it does for many years to come. We have already heartily recommended the system to a number of people we know in similar situations and will continue to do so in the future.

Worm Farm Septic Tank Systems – Using Worm Technology

An all-in-one affordable alternative to traditional septic tanks.

Hi Ev

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 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!


One of the big pluses for the Worm Farm Waste System is that it NEVER smells of septic wastes like many other systems available. Even when you take the lid off there is only ever the sweet smell of compost.


One of the main factors influencing my decision to purchase a second system was the excellent customer service provided by this family business before, during and after the installation of the system. Because Ev and Alan have designed and built the system themselves you know that the advice and support received from them is of the highest quality and completely reliable.


I have a number of friends who also have a Worm Farm Waste System installed at their homes who are happy with their systems.

We just didn’t want to run with a standard septic storage system given the problems that can sometimes associate themselves with this method of waste collection. The A&A Worm Farm Waste Treatment System has been absolutely brilliant. Once installed you barely know it’s there and the small compost bin that provides access to it blends perfectly into the surrounds. But more importantly it works. All of our degradable wastes make their way into the tank and are never heard of again. There has never been any smell nor maintenance issues and we have even used the treated water to get our garden flourishing beautifully. I would recommend this system to anyone who is looking for an efficient and effective system to treat household waste.


How simple and effective, this system just works. No mess, no fuss, no smell and no maintenance – there couldn’t be a simpler way to treat household waste.


This system is remarkable, the worms just eat through almost anything and everything and the byproduct – water that can be used to irrigate your garden. Environmentally this system is so sustainable yet so simple – more people should be using it to reduce our impact on the Global Environment.


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.

Dear Ev

Anouk and I would like to thank your whole team for your extremely helpful and professional advice and installation of our Worm farm Septic Waste System.


Your fantastic help dealing with the local council and securing us a gravity system was particularly appreciated. Right from our 1st phone call though, everyone has been extra courteous and on the ball, always returning calls/emails and keeping us up to date and fully informed during the process.

During the install I also received great feedback and praise for your system from the council health inspector, this can only add to our confidence in your model and was great to hear.


You went above and beyond during our job. We struck some particularly nasty ground and if not for your perseverance and dogged determination I don’t think the job would have been completed. No one can tell what is under the ground until the first trench is started, and we were surprised at the amount of floating rock that he struck. You were jolted around your excavator in scorching heat for a day and a half and just when we thought it could only get easier, it got harder. The man is an absolute gentleman and I am sure part pit bull, he would not let the conditions beat him.


A huge THANK YOU to you all and looking forward to breeding thousands of worms.


Best Regards

Glenn and Anouk Pavey

Thank you for the installation of my new worm farm, on time and on budget!


Firstly, I must thank you for sending such wonderful technician to carry out the installation. The installer was a delight to have on our site, he was courteous, co-operative, accommodating and above all extremely safety conscious.

It was a pleasure to see such a professional approach to ones work, something that is sadly lacking in today’s workforce. Please convey my sincere thanks to him for the excellent job he did whilst he was with us.


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 worm farms for these.

Thanks again for making this a most enjoyable experience.


Cheers, thanks for everything.

Dear Ev and Allan Duke:


I would like to take this opportunity to thankyou sincerely for all your efforts in the installation of our Worm Farm Waste System in Wamboin NSW.


While everything was not plain sailing in building our new home and we had some difficulties to overcome together. We had two issues; the transpiration area was initially installed incorrectly, then the second installer Matt, installed less transpiration bed (piping length) and without gravel into a new location and it this still remained off the land contour.


Once Allan arrived onsite to install additional drainage capacity you noticed our second install attempt was not installed correctly, still remaining off land contour and also short of what was ordered and paid for. After Allan gave his profound apologies he proceeded to correct the situation by installing additional LPED lines and correcting the run of the existing trenches to now follow the correct land contour.


While Allan could have proceeded to perform correction activities and add additional capacity by the way of additional RELN drain and charge us for this, I may have remained none the wiser, however the integrity and professionalism of you Ev and Allan and Worm Farm Waste Systems I have found uncompromising, I was quickly informed of the installer error and it was all corrected without any need from us to push for a resolution, this is something that is so rare nowadays. Yes we had issues and this is something you have been happy to acknowledge and correct without fuss of complaint. The system now I believe is installed correctly and functioning as expected and designed to do so.


Once again a big thank you to all who have assisted us, Ev, Allan, Liz and Tony, it is the uncompromising commitment to deliver a system to an exacting design and specification with an honest commitment that is very rare indeed today.


I am still espousing the benefits of your systems and will continue to do so, not only do they deliver an excellent, environmentally friendly waste management system, it’s how you and your company have handled our situation with integrity. Thank you.
