Retrofit Your Existing Septic Tank

With An Eco-Friendly Septic System

We can Retrofit 80%-90% of existing septic tanks and aerated wastewater treatment plants

We have designed a cost effective method to treat sewage, wastewater (grey water) and organic waste in an energy efficient way. For example if you look at the service and energy costs for aerated wastewater treatment plants, or if you are tired of the septic tank smelling, it would be very easy to justify a conversion to a Worm Farm Waste System. For a 4 bedroom house the average cost to run the system is approximately $20 per year. 

This powerful organic septic system will effectively processes sewage, all household sewage, 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.

What Do We Need To Retrofit Your System

To retrofit your existing system we require a septic tank chamber that is in good structural condition with a capacity of at least 3000 litres. We would remove the baffles and convert your old system into a eco-friendly Worm Farm Waste System.

The vent pipe can either be:

  • Freestanding coming from the bottom of the chamber
  • Attached to the building if appropriate

The Worm Farm Waste System is not mechanical. We have harnessed Mother Nature by using worms to process your sewage, wastewater and organic waste. If you have a large crowd at your home the system will easily cope, unlike treatment plants which just stop working or the traditional septic tank which smells. Our eco-friendly systems can take high peak loading and additional energy consumption is not required for processing. Let the worms do it naturally. Unlike wastewater treatment plants and septic tanks, our system has the added bonus of processing organic waste. Up to 90% less organic waste could leave your site for landfill if you decide to retrofit.

Some tips on how to operate our system 

  • Recyclables such as plastics, bottles, cans, foil containers, tetra packs etc. require disposal off site.
  • Newspapers and cardboard should also be recycled and not added to the Worm Farm Waste System as they do not break down quickly enough.

We are sad to leave our little block, with the worm farm the best choice we ever made for the block, But due to health and family issues, we have moved to Brisbane and now dealing with the city sewerage system. Thank you so much, especially to Alan who was so wonderful to Doug when he installed our system. Doug loved him . Thank you again.

We've had our system for over 2 years now and it's been the smart choice of the septic systems we looked at. The running costs have been minimal and its needed no maintenance. It's been excellent using the system day to day including the disposal of our organic waste. Big plus for the environment as well. Highly recommend this septic tank system to anyone. NSW Central Coast.

I totally agree with Gill from Vic. The worm farm waste system is absolutely fantastic. Its been running without a hitch for the last 4 years and garden looks great. For anyone considering a septic system please take the time to look at this one. You will not be disappointed.

It just looks after itself!

We have this system for our house in NE Vic - family of four, plenty of visitors, two toilets and bathrooms and washing machine/dishwasher running most days. There is nothing different inside the house, and the unit sits outside the house and just runs itself. Occasionally we throw in a dead rabbit and green compost from the garden. I can't understand why anyone would want a septic system with regular maintenance costs, when this has none and is eco friendly as well. The company dealt with our local council for the permit with no problems. It has definitely been the way to go for us.

I am an existing client with A & A Worm Farm Waste System and have been for 8 years. I cannot agree with the review posted by Julie C on so many fronts. Our experience during the entire permit process, co ordinating the installation and after sales service has been very impressive. After 8 years we have never had a problem with the system, appreciate the fact all our food waste & organic matter are able to be disposed into the system with our garden benefiting from the beautiful worm liquid. Any time we have asked a question the response has been very professional and helpful. We have recommended this system to all our friends and neighbors The internet is a marvellous tool however can be used in such a negative way by competitors

About The Frog

We use the frog as a mascot on our website, brochures and vehicles because they are excellent indicators of local environmental health. Frogs disappear when the environment is under stress and return when conditions improve.

It is not unusual to find frogs living happily in our Eco-Friendly Septic Tank Systems and as they die in polluted water. What better proof is there of how healthy the environment becomes when you install one of our systems.
