When the sun creates water…

Helped by climate change, drinking water is a scarce ressource :

20% of the world's population does not have access to it.




One of Rotary International's causes is to provide

clean water, sanitation, and hygiene

--- Our motivation? ---


Help make drinking water accessible to populations in need.


For our projects, we have selected Helio, an innovative technology, which easily transforms any water, even unsanitary, including seawater, into drinking water !

HelioWater is

  • Powered only by the renewable energy of the sun

  • Autonomous, affordable and sustainable

  • Indispensable for humanitarian projects and disaster relief

  • Delivered in a box, easy to transport, install and operate

The HelioWater process of distillation and mineralization guarantees drinking water of the highest quality.

Its high level of productivity has never been reached until now: each module of 1 m² produces 10 liters of water / day(*)


(*) value obtained under conditions of solar radiation of 8 kW / m² / day

HelioWater is designed to be

  • Quick and easy to install

  • Extremely low maintenance

       (long service life, over 30 years)

  • Resistant to weather and storms

  • Profitable

HelioWater is particularly suitable for refugee camps or coastal populations, where the local available water may be unsafe for human consumption.

HelioWater can also produces pure, distilled water which may be needed for use in medical facility or hospitals.
