Black & Grey Water Treatment

Initially I was thinking I’d make the tiny free house more like a ‘park model’ house with a flush toilet and RV hookups. But the more I learn about sawdust toilets and soil box gray water systems the more I think that these two solutions are really a better way of dealing with the waste water and sewage.

In addition to being free, these methods are far more sustainable, provide usable compost, and don’t require massive quantities of water. The sawdust toilet does require a special compost pile for the turds to cook. I’m also pretty sure few government agencies officially condone these little methods or handling human waste so before trying this yourself be sure to check your local laws.

To learn more about sawdust toilets and gray water soil boxes get the Humanure Handbook. You can also read The Humanure Handbook online free but this is one book you might want a hard copy of in your library. It makes great toilet reading too… (pun intended). Photo credit to Jenkins Publishing.
