UNESCO/IHE - eSOS smart toilet

UNESCO/IHE - eSOS smart toilet

In disaster areas where many people live together in poor conditions, diseases are lurking. Sanitation plays an important role – a hole in the ground or overflowing emergency toilets are breeding grounds for bacteria and viruses. If the flow of waste is better managed, the risk will be reduced and the quality of life will improve considerably. To address this issue UNESCO-IHE and partners supported by the Bill & Melinda Gates Foundation have envisioned a award-winning eSOS smart toilet (or iToilet), one that is not only hygienic, safe and affordable, but also serves as a source of information about the situation in an area and the toilet’s users.

The eSOS toilet is being tested in the Philippines for functionality and acceptance. This lightweight, easy-to-maintain toilet is equipped with sensors that collect the relevant data using a specially designed operation software. Based on this information, the separate urine and faeces tanks can be emptied at precisely the right moment to be processed into water and fertilizer. Also, by tracking the individual user’s data, experts can identify imminent malnourishment or dehydration (diarrheal disease) at an early stage. The toilet fits in a compact package that is easy to transport - the shipping pallet transforms into the toilet’s foundation during installation. The water tanks  are incorporated into the walls and the urine tank is part of the stairs. The aim was to make this toilet as functional as possible for the lowest possible price.
