Three separate decomposition toilets are required for two people. They do not need to be tall with stairs. Three holes in the ground with a comfortable seat have proven sufficient for two people, except for the lack of a sanitary fly trap, and the ease of removing decomposed material. If the three chamber system of holes in the ground is used, fly trap light may be introduced with properly positioned pipes. Holes should be located on high ground, away from streams, and where underground water is too deep to be contaminated. The stairs illustrate scale, they are not necessary. Entrance of light and the door at the bottom are details of design summarized to create a comfortable and sanitary design which creates value and relieves stress on water resource purity.

The human body utilizes about fifteen percent of the value in food. Eighty-five percent of the money, work, forces of biological life and solar power in food is thus deposited in the compost toilet. The idea is to use several toilet compartments for decomposition. Retrieving the fertilizer is a pleasant experience after passage of sufficient time.
Several families, including my family, lived with versions of this system for over ten years in Santa Barbara, California. The entire neighborhood was destroyed by fire in the year 2008. This functional system which creates wealth instead of pollution has been lost, possibly forever.
Toilets of decomposition similar to this are very inexpensive, they do not require maintenance, and create wealth instead of pollution. Instead of injecting sewage and chemicals into rivers which are drinking water for the next town, decomposition toilets retain eighty-five percent of the food value to fertilize soil. Eutrophication is the proper term for nutrient fed algae blooms which choke rivers, then flow with the river, and create dead zones in the sea. Ecological economics tells us we must learn to avoid polluting water while wasting most of the ten calories of oil required to produce one calorie of food.
The compost toilet is another product which is an income source for those who learn this technology. It also clearly illustrates how the physical laws of entropy become usable knowledge for those who are considering a sustainable replacement for corporate consumerism.
The decomposition toilet creates wealth, it does not use or pollute water.
