Rainwater harvesting enables utilities to curtail maximum needs of water during summer months. This method can act as a considerable backup water supply for emergency circumstances. Complete answer: Rain water harvesting is a technique of water conservation by collection of rainwater primarily from the roof into a tank. It can then be utilized for numerous objectives. One significant application of obtained rain water is to replenish the groundwater. Rainwater harvesting is a simple strategy by which rainfall is collected and conserved for future usage. It includes collection and conservation of rainwater with the aid of artificially manufactured techniques, that runs off natural or man-made catchment regions, for example rooftop, rocky surface or hill slopes. Rainwater Harvesting is unrestricted from any sort of contaminant, with limited storage cost and no maintenance cost, except for periodical cleaning. Surface runoff harvesting and groundwater recharge are the two primary techniques of rainwater harvesting. Hence, the correct option is B. Note: - Reserving rainwater can enable replenishment of regional aquifers, decrease urban flooding and most notably, assure water availability in water-scarce zones. - Although rainwater harvesting estimate is considered to be a desirable notion since the last few years, it is scarcely being enforced in rural India. Madakas, Ahar Pynes, Surangas, Tankas are some of the ancient rainwater harvesting methods observed in India.
