WADI - A solar-powered UV measurement device that visualizes the process of solar water disinfection

WADI™ is a solar-powered UV-measurement device, which indicates the process of solar water disinfection in a simple manner. Obtaining safe drinking water with WADI can be achieved through five simple steps. The solution is tested and endorsed by the World Health Organisation, meeting its microbiological performance criteria and is classified for providing targeted protection. WADI is simple, reliable, and easy-to-use. It requires no spare parts, consumables, and is the first water disinfection product without accumulating running costs for the user.

According to the World Health Organization (WHO) 663 million people still lack access to drinking water sources that are protected from external contamination. The absence of proper water disinfection triggers health and environmental issues that translate into worldwide economic problems. People in rural areas of Least Developed Countries (LDCs) are the most affected and have poor access to safe drinking water. The currently available methods in a household to disinfect water are expensive and have associated health and environmental problems such as toxicity, CO2 emissions, and deforestation. WADI allows households to obtain safe drinking water through a solar disinfection process. It is an external device that indicates the progress of the disinfection process of the water. Therefore it can be used with any PET or UVpermeable glass bottles.
