Smart eSOS toilet for emergencies

The emergency Sanitation Operation System (eSOS) concept provides a sustainable, holistic and affordable sanitation solution during the aftermath of a disaster. The eSOS reinvents (emergency) toilet and treatment facilities, and uses ICT to bring cost savings to the entire sanitation management chain. The toilet will improve the quality of life of people in need during emergency situations - from natural to anthropological disasters - and minimizes the threat to public health of the most vulnerable members of society.

The eSOS concept was developed by UNESCO-IHE Institute for Water Education. The experimental prototype of the smart toilet was developed in collaboration with FLEX/The INNOVATIONLAB and SYSTECH and is funded by the Bill and Melinda Gates Foundation-funded project SaniUP - Stimulating local innovation on sanitation for the urban poor in Sub-Saharan Africa and South East Asia.

Smart features

The eSOS emergency toilets are easily deployable in disaster areas because of their robust and light-weight specifications. The smart eSOS toilet includes some unique features in the prototype that will shed new light on how the toilets are used in emergencies. This includes remote-sensing monitoring, an energy supply unit, GSM/GPS sensor/card, occupancy sensors, urine/faeces accumulation sensor, an S.O.S. button, and a communication system that allows for data collection by remote sensing and their transfer to an on or off-site emergency coordination center. The data resulting from the use of the toilets will allow the toilets as well as the entire sanitation management chain to be improved.

Field testing

The eSOS toilet will be tested further in a refugee camp in the Philippines in September with support of the Bill and Melinda Gates Foundation and the Asian Development Bank. UNESCO-IHE PhD fellow Fiona Zakaria from Indonesia will carry out further experimental testing in cooperation with relief agencies on the ground. The eSOS smart toilet design prototype will be manufactured based on the results and feedback obtained from the experimental application. The working prototype and a 1:10 futuristic scale model will be on display at UNESCO-IHE until end of August.
