Globally, 2.6Bn people lack safe toilet access, and 1Bn defecate openly. Chronic under-investment into sanitation infrastructure means people in many poor and vulnerable communities live with their sewage. With no toilets or pipes, there is no way to flush. change:WATER Labs is developing a low-cost, compact, waterless toilet for non-sewered households and communities. Within the 40% of the world who lack proper access to sanitation, a deeper problem lies for women and girls. 20%-40% of girls drop out of school because of inaccessible or inappropriate toilets. In many areas, women and girls are at risk of assault and violence with their current solution. change:WATER is particularly motivated to help develop solutions for this subset.
