Technique: WATER HARVESTING IN POOLS AND CISTERNS
Definition characters description and diffusion
Water is the most precious underground resource: water dripping from walls, seeping out from the rocks, forming puddles. In some caves, vapour-laden air caused by the heat coming up from the magma under the earth’s crust are condensed along the walls to produce water.
General characters description and diffusion
In prehistory, seeping water, as well as water dripping from stalactites was collected into pools carved out under the stalactites inside specially made cavities. Caves kept a constant temperature throughout the year and were the ideal shelters for human beings and animals, for the storage of grain and mainly of water.
Advantages and sustainability
Water harvesting in pools and cisterns is beneficial because it is a source of water that is available all year round. It also takes place in a setting that is ideal for human activity in the cold of the winter or the heat of the summer.
