Components of Rainwater Harvesting
Catchment from where water is captured and stored or recharged
Filtration methods used to remove pollutants from collected rainwater
Conveyance system that carries water from the catchment to the recharge zone
Storage tanks and/or various recharge structures
Why Harvest Rainwater?
Factors such as climatic changes happening at a national and global levels are causing water levels to fall. Overpopulation has resulted in the increased acquisition and development of land that has resulted in the depletion of our water bodies. Several areas are critically affected by a dearth of usable water.
As a result of accelerated property development in our cities, the greatest requirement for critical resources such as water is focused in urban areas. The earth’s surface is 70% water, yet, very little of this is actually usable or drinkable. It is very likely that we will shortly reach a stage when the quantity of usable water present on the earth’s surface won’t be sufficient to satisfy all our requirements.
Rainwater harvesting is the solitary realistic option to counter the growing menace of rapid water depletion. It involves accumulating, filtering and storing rainwater to be utilised for assorted industrial and residential purposes.
