HELIO, drinking water for all

Currently, there are 2,1 billions people worldwide who do not have access to drinking water in their home, and 780 million people worldwide who do not have access to drinking water (UNICEF). A major health hazard and main cause of global mortality.

Transparent glass spheres, naturally heated by the sun at temperatures of over 100°, separate the bacteria from the drinking water. Its only energy source is a solar panel that powers the pump which fills the sphere. The system adapts to all types of water course comprising of water that is unsafe to drink (seas, lakes, rivers, ponds). Each sphere can produce up to 10 litres of water per day of sunshine, which is the equivalent of the drinking water needs of a family of five. It also has a minimum life-span of 30 years.

Helio is an inexpensive stand-alone, decarbonated and decentralized system that can easily be installed in areas without drinking water infrastructure and also in disaster areas in the wake of natural disasters.

A pilot farm in Saint-Raphaël

Three years of research and development were necessary to design the system, which was tested in Saint-Raphaël from September to December 2017, using a pilot farm. A full-sized demonstrator that can meet the needs of 25-35 people all by itself, all while guaranteeing a lower cost than a liter of mineral water.

A recent edition of Natural Sustainability journal reveals that one out of every two cities may experience water shortage by 2050, HELIO launches the installation of its first plants, both of which are still under construction and located in the Middle East.
