Drinking water images – Fog to safe drinking water
Drinking water images – fresh water in the air.
fork catchers or fog nets are helping to supply safe and clean drinking water
to impoverished families who live in the outskirts of Lima, Peru, in the Atacama Desert,
which is known as the driest place on Earth.
The National Geographic Society considers the coastal area of southern
Peru to be part of the Atacama Desert and includes the desert south of the Inca region in Peru.
In Lima, one out of every five families or almost two million people don’t have
access to safe drinking water, which can cause disease.
Instead, they must rely on costly outsource water that’s delivered by
trucks and aren’t often reliable.
This also has a high CO2 footprint. Thanks to a compassionate and innovative
project launched by the Dutch non-profit Creating Water Foundation,
sixty four nets have been set up to provide almost 500 families
access to 10000 liters of safe drinking water, which is also used for local
folk farms to grow organic food locally.
This forward thinking folk farming technology relies almost entirely
on the presence of frequent fog and wind.
The critical factors for the success of folk farming technology include
the density of the fog, wind speed and direction and the material of the mesh.
Made from polypropylene nets, these lifesaving fork catches collect tiny
water droplets from the fog.
They’re ideal for dry coastal areas with high amounts of fog,
which can carry large quantities of fresh water in the air.
For optimal results, the fogginess are strategically placed on hilltops,
the storage tanks are placed in deliberate locations in the valley and
use gravity to transport the collected water.
Once folk forms in the area, it makes its way through the nets and
tiny droplets of water come together to form droplets heavy
enough to move down the nets and into tubes.
The collected water is then stored in tanks to provide clean drinking water
for the locals and to produce food sustainably. The key factors are wind condensation and gravity.
What’s great about fog farming is the fact that it’s a passive solution,
meaning that it doesn’t require any energy.
Besides the filtering process, the Creating Water Foundation points out
that it completely depends on the forces from Mother Nature,
where the water can be utilized to drink safely or grow crops.
