Short Essay on Rainwater Harvesting (200 - 250 Words)
Rainwater harvesting is the method of storing and utilizing rainwater for further purposes. It is a good method of water management. This method is very essential in arid and desert areas where people usually face a shortage of water. Rainwater harvesting is a method with low capital and high benefits. It is also helpful in preserving the groundwater level.
Rainwater harvesting helps in fulfilling the water requirement of the society. Using this method, no water from the rain gets wasted. People can perform rainwater harvesting either by collecting water on the rooftop and then transferring it into underground tanks or by collecting surface runoff water in the ponds. Both methods are highly effective to collect rainwater. It also saves us from soil erosion, drought, and floods. Rainwater harvesting is an eco-friendly method of saving water that also controls the water cycle in the environment.
However, rainwater harvesting does have some limiting points. This method is only applicable to areas that receive a good amount of rain. Rainwater harvesting remains of no use in areas with low rain. Another thing is maintenance. Due to continuous water storage, there can be a chance of the production of algae and dangerous insects. Therefore, proper maintenance is necessary. Sometimes, rainwater harvesting can suffer a storage problem. Limiting storage can fail to store high rainfall.

Rainwater Harvesting Methods
Rainwater harvesting is a successful method of collecting water that is performed in many places. There are two basic methods of carrying out this process. They are:
- Rooftop harvesting: This is the easiest and most convenient method of performing rainwater harvesting. In this method, the roofs of the houses are made in such a way that the rainwater gets collected. This water is then transferred to the underground tanks through pipes. Roofs of some houses are made slope and the edge is then connected to the tank where water gets collected. This stored water can now be used for many household purposes. Many people prefer this method of rainwater harvesting.
- Surface runoff: Another method of rainwater harvesting is to collect surface runoff water which gets lost in the environment if not collected. In this method, certain arrangements are made that provide a path to collect rainwater from parks, roads, small cities, etc to the tanks or ponds. Gallons of rainwater can be collected through this method. However, water collected through this method contains impurities and needed to filter before use.
Every single drop of water is precious still every year fresh rainwater goes wasted due to a lack of proper knowledge.
