Fog collector group at a hill side - My Bachelor-Thesis had the subject "Drinking water abstraction world wide".
DropNet is a fog collector, that can be a great help for the drinking water supply in isolated areas or areas with a low infrastructure just by using natural and local ressources. The collector filters tiny water droplets from fog clouds and causes the droplets to coalesce.
Extraction of a water sample - Dependent on the conditions, DropNet can collect, 10 - 20 liter water per m^2 a day.
Isolated mountain village in Peru - If several collectors are installed together and connected by pipelines, they could supply a whole village with enough drinking water. Especially villages that are situated in isolated areas or regions with low infrastructure would profit from the system.
Locations - DropNet is constructed to be built up on flat as well as on uneven ground - with or without hillside situations.
Locations suited for fog collectors are especially arid, costal areas with altitudes between 400 and 1200 m, that show a lot of fog accumulation.
Such conditions are not seldom and can be found in many places of the world, so for example in Chile, Peru, Haiti, South Africa, Eritrea, Nepal, Spain or Portugal.
DropNet in a fog cloud
Set up - The tent-like construction can be assemled by a few non-skilled workers.
Dimensions - With a total height of 3 meters and a width of 4.5 meters DropNet has got a net surface of ca. 6 m^2.
Mesh - The net has to be tensed, that it shows a curvature into two directions, building a saddle surface,which creates a stiffness, strong enough to resist strong winds.
The low-priced mesh from polypropylene is a special fabric using horizontal and vertical fibers to create a triangular pattern.
Drain gutters - The drain gutters are connected to the net by weltings and lead the collected water to a small tank.
Water tanks - The small tank has got an integrated filter to clean the water before it is distributed. Pipelines lead the water from the fog collectors to big water tanks in the villages.
