HELIOZ

HELIOZ GmbH, founded in 2010, is a social enterprise based in Vienna, Austria.

A number of years ago the HELIOZ-founder Martin Wesian was travelling through Venezuela. He caught Cholera through drinking contaminated water. Following that experience he dedicated himself to finding new and innovative solution to reduce waterborne diseases.

The concept which got most of his attention was 'solar water disinfection' (SODIS). This method to disinfect water does not require electricity, filters or chemicals for use, but only needs the power of the sun and a PET bottle. However, this smart and efficient method is widely unknown and only applied by a few million people worldwide. Martin Wesian believes that the main reason for this are the difficulties to explain how solar water disinfection works and how to predict the length of this process.

He wanted to create a sustainable and cost-effective UV measurement device to measure the process of solar water disinfection. Because the general feedback to this idea was compelling, Martin decided to realise his invention. To do so he signed up for a Master's Degree in Industrial Engineering in 2007. His MA thesis was about the measurement device, which he later named WADI (for WAter DIsinfection).

The WADI attracted a lot of attention and during the last few years HELIOZ won numerous prices for that invention. WADI has been tested by the World Health Organization WHO and meets its guidelines for drinking water quality. It provides households, schools and communities in developing countries with one of the most cost-effective ways to enjoy access to safe water for many years to come, using nothing other than WADI and the power of the sun.

Following excellent results with WADI in some African and Asian countries over the last few years HELIOZ is further expanding its activities in developing countries. EnTri's good reputation in supporting companies with organizing financing for their market entry activities led to the first joint project in Kenya. The cooperation between both companies is great - so further successful projects can be expected.
