Welcome to Sandec
Sandec is the Department of Water and Sanitation in Developing Countries at the Swiss Federal Institute of Aquatic Science and Technology (Eawag). It aims to:
- develop, provide and facilitate the implementation of new concepts and technologies in water supply and environmental sanitation
- increase research capacity and professional expertise in low and middle-income countries in the field of water supply and environmental sanitation
- raise awareness and enhance professional expertise in high-income countries for water supply and environmental sanitation issues in low and middle-income countries.
Sandec's activities centre on problems of sustainable development in economically less developed countries. Its mandate is to assist in developing appropriate and sustainable water and sanitation concepts and technologies adapted to the different physical and socio-economic conditions prevailing in developing countries.
SODIS - Safe drinking water in 6 hours
|
|
Solar water disinfection - the SODIS method - is a
simple procedure to disinfect drinking water. Contaminated water is filled in a
transparent PET-bottle or glass bottle and |
exposed to the sun for 6 hours. During this time, the UV-radiation of the sun kills diarrhoea generating pathogens. The SODIS-method helps to prevent diarrhoea and thereby is saving lives of people. This is urgently necessary as still more than 4000 children die every day from the consequences of diarrhoea. SODIS (abbreviation of Solar Water Disinfection) is an initiative of Eawag. We facilitate the dissemination of the SODIS-method in developing countries. Thereby people in the south get access to safe drinking water and can improve their health in the long term.
