Experiences with grey-water and composting toilets?
Grey-water toilets: The Aqus toilet system (http://www.watersavertech.com/AQUS-Diagram.html)seems like the most popular (only?) grey-water toilet available. I really don’t like the fact that it installs with a purification system and electric pump. Does anyone know of a model that does not have these features?
The concept is simple enough. Has anyone tried making their own grey-water toilet? I’d like to consider using sink drain water to fill the toilet tank and also possibly a small reservoir so as to have two flushes available on demand. Surplus drain water would overflow into the toilet drain.
Composting toilets: Looking for generalized experiences with any type of composting toilet. I have looked at a non-electric Sun-Mar brand toilet close up but didn’t like the 4″ PVC vent pipe that must be installed (with no bends) through the roof to a height 2-3′ over its peak. Is this a typical requirement?
