Each year millions of people, most of them children, die from diseases associated with inadequate water supply, sanitation, and hygiene. In 2015, 2.3 billion people still lacked even a basic sanitation service, and 892 million people still practiced open defecation.
First developed by LIXIL's American Standard brand, the SATO series features a weighted flap under the seat that seals itself after use. Priced from $2 to $10, depending on model and country, they use as little as 200 ml (less than a cup) of water - 80 percent less water than a flush toilet, put a barrier between fecal waste and people, block odors, flies and other disease vectors, and offer an effective, affordable way to mitigate the dangers and unpleasantness of typical pit latrines.
