What People Say

When we first contacted A&A Worm Farm System we received prompt emails, replies and answers. Unlike other worm farm system companies Ev and A&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.

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.
