Composting Toilets

I happen to be writing an article this month about my experience with designing a composting toilet facility for a nature preserve in southern Kentucky. So let me take a few minutes to summarize (sorry - it is long): Toilet systems that use water to carry the waste product away have recently come under scrutiny due to concerns about availability of water. This is of greater concern in the arid west, but all may be subject to some cost of treatment of the effluent. There are two primary wet systems: connected into a municipal sewer or a septic system.
