Hi! Patti, While not an earth-closet, I recommend the Clivus Multrum, it is a commercially available, waterless composting toilet, which uses saw dust, wood shavings etc, in place of the soil. We have been using ours for about five years and are very happy with it.
Hit Google and put Clivus Multrum in advanced search and you will find all you need to know. Gil Patti Berg wrote: > Does anyone on this list know where I can get plans to build an earth > closet?
