According to the current status 2.1 billion people around the world have no access to clean drinking-water. Africa is the most affected continent. In our target region Kajiado Country, Kenya 266,000 people obtain their drinking-water from surface waters which are massively bacterially contaminated. This causes serious diseases like typhoid, dysentery or cholera. Every year on average 502,000 people - especially children - die due to polluted drinking-water worldwide.
