update on the worm farm composter


Here is an updated picture of the idea from Wretha. Just click on the small picture to see the larger one. Notice that air flow goes in one barrel and out the other. I divided grey water and sewage, but really I was just dividing the load between the two barrels. Yes, pun intended :)

You can put compost in either one though. You can have gravity drain for the water output or use a pump (solar powered ideally). Also, the vent pipe is black so it will heat up and act as a solar chimney. As the hot air rises, it sucks air in through the other tank cap.

Also, since the sewage is on the right, it goes through the first worm compost, sand, gravel then through the other gravel in the left bin before exiting.
