Wastewater Workshop with Anna Edey
Our yard was buzzing with several activities at once. While some people worked on building their own toilets, others helped to mix and sift the organic material for the filtering system. Others helped by digging the trench for the filtering box.

Building the Bio Carbon Filter

We made a big pile of brown stuff: leaves, wood chips, peat moss, saw dust, etc. This is the material that eventually becomes the Bio-Carbon filter. But before we let it go, we used a coarsely meshed screen to filter it into a finer dust. This is a close up of the dust we made by filtering the brown materials. It has a nice texture and smell. We made about 3 wheel barrels full and then stored the material to sprinkle into our 5 gallon bucket after each poop. This dust eliminates the odors.

We are fortunate to have a fiberglass greenhouse (functioning as a storage shed) where we decided to install the Bio-Carbon Filter system. The first step was to dig a hole, 1' deep, 2' wide and 8' long.

 Here's the human chain, delivering the brown carbon materials into the box we built (described on next page in detail).
