WADI

Worldwide, there are over 780 million people without access to an improved drinking water source. The problem is usually not water shortage as such, but lack of disinfected, drinkable water. In many countries, drinking water is contaminated with harmful bacteria or viruses. 80% of all illnesses and deaths caused by diseases in developing countries derive from insufficient or contaminated drinking water supply. Each year, 1.5 million children under the age of five die because of unsafe water.

Ex works (Austria) sales prices for WADI range between 13,50-17,00 USD. These prices do not yet include transport charges, duties, local taxes and margins for the distributor. Final prices for end consumers will therefore be considerably higher.
In order to enable the poor to afford WADI, we also encourage companies to take part in corporate social responsibility (CSR) projects, in which they can have WADI branded with their logos and then in doing so subsidize WADI for base-of-the-pyramid consumers.

Stage of development: produced in serial production

WADI is a UV measurement device that visualises the process of solar water disinfection. A happy smiley face will appear on its display as soon as the water is safe to drink.

Solar water disinfection is simple: Contaminated water is filled into a transparent PET-bottle, which is then exposed to the sun. The UV radiation of the sun kills pathogens in the water and can thereby reduce waterborne diseases such as diarrhea. Solar water disinfection is approved by the WHO for being a viable and effective water disinfection method.
