WatAir
Collects dew and rainwater and turns it into fresh water

Water is an essential resource for life and good health. A lack of water to meet daily needs is a reality today for one in three people around the world. Globally, the problem is getting worse as cities and populations grow, and the needs for water increase in agriculture, industry and households.

In order to make safe water more accessible worldwide, the following was taken into account in the WatAir design: Minimal cost for manufacturing, easy and quick deployment in remote places, low technological requirement and the implementation of local materials.

WatAir is well positioned to serve the needs of a number of different users. It has been designed with international development and disaster relief in mind. It folds to less than one meter, weighs less than 3.5 kg and can be made from various materials, making it possible to use local materials. WatAir has many possible uses, including individual clean water supply and treatment. It can also be used for drip irrigation in agriculture or as a supplementary water source. The shelter provided beneath the device can be used to provide temporary living accommodation and can be incorporated into both urban and rural landscapes.
