Abstract:
"Water" is one of the most valuable gift among many offered by God and is the mainstay of the lives of all beings. In the present era, humans are exploiting water indiscriminately and continuously polluting it. Then in such a terrible situation, if we do not think about water conservation, then the day is not far, when there would not be water for drinking. Of the many sources of water, rainwater is a major source and its conservation is called rainwater harvesting. The process of storing or using rainwater through a particular means is called "rainwater harvesting". Rainwater harvesting is done in various ways through roof top rainwater harvesting, small scale dams, bunds, trenches, etc. In rainwater harvesting, the rainwater falling on the roofs of houses, schools and offices is collected in the tanks made of aluminum, iron or concrete and used for domestic use or is connected to the groundwater recharge structure for enhancing the groundwater level. A small dam or "check dam" is a barrier made of mud, stone or cement-aggregate, which is constructed across a drainage ditch/channel to lower the velocity of flow and tie up the excess water in the rain, so that this water can be used during or after the rainy season and this will also increase the ground water level. Implementing rainwater harvesting techniques directly benefits our country and ultimately citizens by reducing the demand on the municipal and public water supply, along with reducing run-off; erosion, and contamination of surface water.
