Access to safe water has been recognized worldwide as a human right since 2010. However, contaminated water continues to be a major problem for the health of the local population in many parts of the world. Therefore we develop SoWaDi.

SoWaDi stands for Solar Water Disinfection: The solar water disinfection systems developed and researched in the project use solar energy to improve the water quality. Since 2010 we have been developing technical solutions together with local partners in rural areas of Tanzania to improve the water situation for families and at schools.

The aim of our project is to ensure that as many people as possible have access to germ-free water, because clean water protects against diseases such as typhoid fever and cholera. To achieve this, a construction manual is available free of charge. This enables everyone to build and install the system themselves using locally available, inexpensive materials.

The work, which continues despite the corona pandemic, is carried out in close cooperation with our local project partner Kilimanjaro Childlight Foundation (KCF). In Tanzania, together with local school groups and families, six of the systems have already been installed. The local supervisors of the facilities regularly collect and evaluate the data, which is then used to continuously optimize the facilities. In this way, we want to identify possible weaknesses, improve effectiveness and contribute to a long-term and sustainable solution for rural water supply. In July, a team from KCF was able to visit the plants and ensure that they were back in operation in time for the beginning of the dry season.

If you would like to know more about how our solar water disinfection system works, how we continue the research and development work together with KCF in Tanzania despite Corona, or if you have any further questions, please take part in our online event in German language “SoWaDi introduces itself: Solar energy for clean water” on Thursday, 29.10. at 19:00!
