World Toilet Organization

World Toilet Organization (WTO) is a global non-profit organization committed to improving toilet and sanitation conditions worldwide. WTO is also one of the few organizations to focus on toilets instead of water, which receives more attention and resources under the common subject of sanitation. Founded in 2001 with 15 members, it now has 137 member organizations in 51 countries working towards eliminating the toilet taboo and delivering sustainable sanitation.
