I found this on http://www.wormfarm.com.au/domestic.php . It is a worm farm in a tank that you bury underground. It can take all of your houses sewage and grey water and there is a compost cap on top that sticks out of the ground. You can throw ALL kitchen waste, including meat, into it. You can also throw all paper and cardboard into it. It eliminates 75% of your garbage.The water that comes out the bottom is odorless and full of worm castings and great for the garden. This system is meant to replace or be used instead of a septic system.
