Anorve has added an entrepreneurial element to his efforts by designing and selling attractive toilet fixtures. He collaborates with a nonprofit organization, Espacio de Salud, and together they have made the double-vault toilet widely available, with the construction supervision and maintenance necessary to build them correctly and keep them functioning properly. It doesn't work. It has been demonstrated over and over again that there is an infinite number of ways to build a composting toilet so that it does not function well. Training and supervision take care of this.
Regular maintenance keeps the toilets working.
Homeowners need support for these things. Add to this the fact that there is a social change element to the project, and you can see why a blueprint won't do the trick. Providing sustainable sanitation technologies for billions of people will require replacing the existing engineering and financial infrastructure that currently supports sewerage with one that supports ecological innovations in waste treatment. And whatever the technology, people will have to want it. The fact that half of the people in the world do not have a toilet reflects government priorities that are politically and morally bankrupt.
