Developing and deploying

safer, smarter, more

dignified sanitation



This is the mission of change:WATER Labs


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.

Focusing on Women and Girls

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.

No innovation has saved more lives in the last 200 years than the flush toilet and sewer system. But we need new approaches to ensure the 40 percent of humanity without access to improved sanitation has a safe and affordable way to go.
