WADI: Safe Water. Easily.

Helioz aims to provide an affordable and efficient solar water disinfection tool for low-income households and humanitarian organizations around the globe.

Our organization has developed a sustainable and cost-efficient point-of-use solution for the lack of safe drinking water, called WADI, to reduce waterborne diseases, child/infant mortality, and health care expenditures and equally increase social development.

Through our core business as well as with our research and development activities, we seek to contribute and commit to the MDGs. Our flagship product WADI is also directed toward the MDGs 3, 4, 6 and 7c.

The WADI device traces the progress of solar water disinfection in a PET bottle by detecting and calculating the UV-A rays of the sun, indicated by a status bar and smiley face. WADI makes the SODIS procedure attractive, calculable and visualizes the method for end-users. WADI is made of recyclable plastic, in line with cradle to cradle design which stands for eco-efficient production. With its built-in solar panel, WADI is energy-self-sufficient, affordable and needs neither spare part replacement nor maintenance for at least five years (guaranteed). Internationally understandable pictograms on the device facilitate correct usage. WADI is not only meant to be a life-saving tool which satisfies basic human needs but also a lifestyle product which brings easy and inexpensive solar water disinfection to remote low-income households.
