2.5 billion people lack access to adequate sanitation facilities worldwide, and instead of having a safe and clean environment for taking care of their bodily wastes, they are forced to rely on the most primitive of toilets, such as a hole in the ground, or poorly designed and maintained latrines. These conditions result in the death of 4,000 children each and every day (!) from preventable water- and sanitation-related diseases, and that's not accounting for the mental and emotional stress that comes from having to resort to open defecation, nor the huge impact that lack of toilets has on education, especially for girls and women. The Wish for WASH organization developed a unique toilet appliance that could be a cornerstone of community-led solutions to water- and hygiene-related disease in the developing world. SafiChoo uses a modular design, which allows communities to choose the configuration that best meets their own cultural needs, whether it's squatting vs sitting or washing.
