SATO:
Preventing the transmission of disease and odors, and reducing open defecation
Having to defecate in the open, into a pit or over a pit latrine, exposes millions of people to odors and disease. To combat this problem, LIXIL has developed the SATO (Safe Toilet) series of products, the first model created with funding from the Bill and Melinda Gates Foundation and launched in Bangladesh in 2013.
Users pour in less than 500 milliliters of water to flush away waste, after which an airtight, counterweighted trap door quickly seals to block smells and flying insects. SATO products are safe for children, easy to clean and affordable. Each one is designed to suit the needs and preferences of users in different regions. Already more than 1 million are in place around the world, improving the lives of 5 million people.
