Early 2007 a Naiade was installed at a boarding school in Arusha Tanzania. Absence rate due to sickness was reduced with 60%.

Before that time, a lot of people got sick from drinking unsafe water. Buying safe water or boiling the water, is just too expensive for most people.The Tanzanian government provides water at sufficient quantity, but cannot guarantee the right quality. The use of Naïades on a greater scale is a simple and effective way to decrease the number of sick people in Tanzania.
