The water harvest Rainfall could be one of the answers to the shortages caused by climate change. This technique is nothing new, in fact its use has been a deep-rooted practice since ancient times, details National Geographic.
According to the World Water Partnership, elaborate systems of water collection, transportation and storage have been documented in various civilizations such as the Minoan in Greece in 3500 BC; that of the Indus Valley between 3000 and 1500 BC; the Mayans in Central America in 2000 BC, and the Incas in Peru from 1200 BC
In fact, another technique for harvesting water is to extract moisture from the fog.
How does water harvesting work?
The black clouds that cover the sky and discharge their rain could be the answer to the scarcity of water since storage and use can mean that there are reserves to guarantee the supply of water. drinking water.
In the case of domestic use, good storage can guarantee supply for up to six months for an entire family.
As described by National Geographic, rain collection consists of directly capturing water using the roofs of houses, schools and different buildings.
These direct the water towards channels and pipes until reaching filters that retain impurities and solid elements. Subsequently, the pump sends the water to an elevated tank that distributes to the faucet.
The amount of water collected will depend on the roof area available for collection.
In the case of fog harvesting, it consists of capturing water droplets suspended in the air using special meshes, strategically installed. These drops condense and are collected in containers. This technique effectively harnesses a scarce resource, transforming moisture into a usable source.
However, the use of fog depends on its density and is limited by air currents; Furthermore, a large amount of land is required to install all the necessary infrastructure that makes water collection possible.
