Wasserstand
Changing Water Sources in the Alpine Regions
The mountain huts of the Swiss Alpine Club are facing a shortage of drinking water: glaciers are vanishing, springs are drying up, and the hut keepers feel the strain of this serious loss. «Wasserstand» («Water Line») extracts 100 litres of drinking water from the air every day, so fewer guests need to be turned away. This sorption-based system can be attached to existing huts and is retrofittable, visible and transferable.
A salt solution draws water out of the air. Heat causes it to evaporate. Condensation turns it back into water.
The two modules cover one third of the drinking water consumption of an average SAC hut.
