Solar water purification for clean drinking water

Objectives:

The objective of the project was to train the population in three regions of Togo to apply a water purification method called SODIS (Solar Water Disinfection), in order to combat infant mortality by reducing cases of diarrhoea following the consumption of contaminated water. Simple and inexpensive, this method of disinfecting water consists of filling previously washed PET bottles with water and exposing them to the sun for at least six hours.

 

Results:
16,000 families, 1,600 groups and 6,000 pregnant women were trained by qualified instructors, whilst 120 nurses and midwives trained one hundred people each. A total of more than 150,000 people thus received training in the SODIS method. An impact study revealed that families generally integrated the method well, reducing the risk of diarrhoea among children under five by 54%. The lessons given by nurses and birth attendants’ show that young women and young mothers welcomed the method. The project achieved its goals of significantly improving the quality of life of families, and reducing infant mortality in the regions.

 

The NGO:
SODIS (short for Solar Water Disinfection) is an initiative of Eawag, the Swiss Federal Institute of Aquatic Sciences and Technology. Its mission is to provide people in developing countries with access to clean drinking water.
