Our activities

Every installation of one of our simple and sustainable solar systems SoWaDis or SuMeWa is financed by donations. The projects are mostly carried out together with the local work force. Thus, affected persons are turned into parties involved.

Often, we also build or renovate the sanitary facilities, especially the toilets. For the waterkiosk foundation it is important that living conditions develop in a positive way on all levels, which is why we put the emphasis not only on providing access to clean drinking water, but also on improving hygiene.

In case the drinking water is sufficient, we also encourage the use of untreated water for the irrigation of fields. This is an important contribution to increasing agricultural productivity and combating hunger.

Our projects are always long-term: we don’t just build wells and then leave, but also involve the local population from the very beginning, assess the overall situation (drinking water, washing facilities, toilets, agriculture), rely on the sun as an energy source, use simple and low-maintenance technologies, and visit our projects regularly after completion.

Water is a human right

The water supply problem in many countries of the world has gradually developed into a real water emergency. As a result, the un recognized water as a human right in 2010. The aim is to provide water and sanitation to all people.

Clean drinking water is vital.

Water shortages and lack of access to clean drinking water affect countless people around the world and have dramatic consequences:

  • 2.6 billion people worldwide have no access to clean drinking water or a suitable drainage system (latrines, washing facilities).
  • 50% of the population in developing countries suffer from a disease transmitted by water or lack of hygiene.
  • More than 2 million people die every year from waterborne diseases. That is more than 5,000 people per day.
  • More than 500,000 children worldwide die every year from diseases caused by poor water hygiene.
  • Lack of access to clean drinking water is the second leading cause of death in children worldwide.

With over 945,000 km2, Tanzania is almost 23 times the size of Switzerland. In mid-2017, the country had 54 million inhabitants, making it the 26th most populous country on earth.

Life expectancy is very low, only three percent of the population is older than 65 years. The largest age group are boys under 25 years of age, they make up about 65% of the total population.

Tanzania actually has plenty of water, as the country borders on the three largest lakes in Africa and is crossed by many rivers. However, access to water varies widely from region to region, and apart from this water scarcity due to the geographical location, the main problem is water quality.

In the cities, the supply of clean drinking water is reasonably good, as 80% of the urban population has access to clean drinking water.

Unfortunately, things are different in the countryside: only 37% of the rural population has access to clean drinking water, about half of them have no alternative but to drink polluted water. Water-borne diseases such as diarrhea and cholera are affecting a large number of victims.

In terms of basic sanitation, the situation is even worse: only 37% of the urban population and 17% of the rural population have access to adequate sanitation. One tenth of the country’s population does not have access to toilets.
