Interdisciplinary project on water and sanitation was performed in Burkina Faso from 2010 to 2015. The title of the project was “Development of sustainable water and sanitation systems in the African Sahel region”, and the project was supported by SATREPS (JST and JICA) and collaborated with International Institute of Water and Sanitation (2iE). The main purpose of the project was to develop and demonstrate the new system of water and sanitation based on the concept of “do not mix” and “do not collect” water and wastewater. In the project, we have proposed the following concept that the water and sanitation system is not a technical system, but it is characterized comprehensive system which includes functions for institutional design, finances and human resources development. The project proposed several element technologies for sanitation which includes composting toilet; gray water reclamation unit; urine recovery unit; and agricultural technologies for effective uses of compost and urine and salt management of soil. The project also proposed the business model for installation of the system. New water and sanitation system tried in Burkina Faso will be an adequate system not only for the developing countries, and the proposed system might be considered to indicate the future direction of water and sanitation system.
