10 Lines on Rainwater Harvesting: Rainwater harvesting is the process of storing and collecting the rain that we get due to precipitation for future use. This water is stored in a tank, a cistern, or even a pit. The water can either be taken out of the system using a pump, or it can be hand-drawn in case of a shaft. The pit is generally in the form of a well or a deep shaft. It is helpful in the places where irrigation is necessary to grow crops, and rainfall is scanty. It can also be used for the household purpose of cleaning and cooking. Most of the time rainwater is very safe to use directly. But it is very much recommended to boil or filter water before consuming it.
