(i) Yes, Subhash is correct in his approach.
Collection of rain water results in prelocation of water under the ground and it thus helps in recharging of the ground water. This process of saving rain water is known as Rain water harvesting. Rain-water is very helpful as the stored rain-water doesn’t evaporate and also doesn’t promote the mosquito breeding. The rain-water harvesting helps in recharging of wells and it remains pure as it is not affected by contamination by human and animal waste.
(ii)The value shown by the Subhash is that water is very important for the survival and it should be used judiciously and not be wasted.
