A bit dated probably but still good information and ideas for dry toilets, grey water systems, etc. I see copies are still available on line. I always wanted to try the wheeled cart rolled up under the bench seat used at the Tassajara Zen Mountain Center for their guests...a more efficient sounding system than the five gallon bucket (which we use) if you have an outside building.
