I couldn't be happier

5.0 rating

Hi Liz,
thank you for your email.
Everything went really well during the installation, apart from the horrendous force 9 gale blowing for the entire weekend – poor Alan, he must have felt like he’d been in a wind tunnel for two days! (I really appreciated his advice on creating windbreaks though – and his ability to remain undaunted!)
It was wonderful to meet Alan, I feel quite privileged that he installed my worm farm.
In fact, it has been a real pleasure dealing with your company (A&A) Liz, right from the very first call with Ev, through to being on hand while Alan installed the system, and all our communication in between, I’ve really enjoyed the whole experience. At all times throughout the process I felt like I was in safe hands, more importantly, your communication and guidance along the way has been brilliant. I think what I really appreciate most is that I felt like I was chatting with friends any time I spoke to you, or Ev or Tracey. That made me feel valued.

A Grand Worm Farm

5.0 rating

We have had our A & A Worm Farm operating now for 8 years at our property in Inverloch. This amazing system devours our green food/garden waste as well as the human waste without any smells or noise-giving us a feeling of deep satisfaction and amazement for the many visitors to whom we have raved about the system.
The Worm Farm is a critical part of our holistic Sustainable house and lifestyle establishment here at Inverloch.
I would have absolutely no hesitation recommending to anyone to consider install such a system and talk to the team about how creative one can get integrating the final effluent with your landscaping/plantation ideas.
Sorry to the A & A guys for being slow to post the review but at least readers can be assured of the longevity of the system.
I’m happy to answer any User type queries any prospective system purchaser may have

Bush Fires Burned Our Septic System

5.0 rating

I installed an A & A Worm Farm Waste System on my rural property November 2003 in the NSW area of Cessnock. Unfortunately the 2019 bush fires burnt the system. I immediately arranged for a replacement system to be installed. The new system was installed efficiently in March 2020.
This is the first time I have spent any money on our septic system in 17 years. The best lost cost system on the market.
