[citation][nom]jtt283[/nom]Unless this can be done with cheap, readily available "household" chemicals, I think reducing the amount of water needed is likely to make a lot more sense from a conservation perspective, most of the time. Otherwise, I can envision some other sort of [expensive] consumable(s) being required, not to imagine the cost and expertise required to make any needed repairs. A part of the world that is unable to supply even rudimentary plumbing is not likely to possess the means to ensure delivery and replacement of other consumables.[/citation]The only chemical that is needed is chlorine. I work at a wastewater treatment plant as an operator. It requires bacteria in an aerobic environment to breakdown the organic material into sludge, or you can do it anaerobically and produce methane, either way you get sludge that needs to be dried, then it can be turned into fertilizer, the water that's left needs aerobic bacteria processing, then tertiary treatment to make it drinkable, after it has been disinfected with chlorine. I have no idea how they plan to make this happen. It needs constant feeding for the bacteria to stay alive (consistent feeding)... Wastewater Treatment Plants are a NECESSITY.
