A very good morning to one and all present here. Today, I will be giving a short speech on the topic of rain water harvesting.
Wikipedia defines the term as follows: “Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.”
Broadly, there are various types of rain water harvesting. Namely, they are Water Butt, Direct-Pumped (Submersible), Direct-Pumped (Suction), Indirect Gravity, Indirect Pumped, and Gravity Only.
Similarly, there are different ways by which rain water harvesting can be practised. They are Rain Barrel Installation, Dry System, Wet System, Green Roof, Surface runoff, and Rooftop rainwater.
Rain water harvesting is an excellent way by which rain water that would otherwise go to waste can be saved and used efficiently. In India, rain water harvesting is made compulsory in every household in Tamilnadu.
