Although close to the three fourths of our planet is made of water, not all of it is suitable for use. The water in the oceans and seas cannot be used as drinking water and little of it can be utilized for other purposes. As a result there is a constant shortage of water that is either good for drinking or home and industrial use.

This slowly started spreading to areas where there was plenty of rainfall. As a result, the modern day rainwater harvesting system was brought into place.
