Fog water collection, Nepal, Peru and Chile
Fog interception technology copies the function of trees and other natural features. It uses large polypropylene mesh nets on ridges, erected perpendicular to the prevailing wind, to capture water-loaded fog, which forms in humid months in mountainous regions or coastal areas. The mesh captures water droplets (1 to 40 μm), which trickle into a collection trough and drain into a series of tanks.
Large collectors are usually 12 m wide and >4 m high. The mesh covers the upper 4 m of the collector, giving a collecting surface of 48 m2, providing fresh drinking water for rural communities.
