In cities like Chennai , increase in apartments & the incidence of concrete aprons restrict the percolastion of rain water in to the ground. Also the conversion of roads in cities & villages to water proof structures also restrict the percolation opportunities of rain water. Thus creating a break in the water cycle. To ensure that Rain Water Harvestin is beneficial is it not ncecessary to have open places that are permeable to the percolation of water to ensure the uninterrupted nature of the water cycle ?
Is it possible for the government to enact a rule / legislation to ensure the presence of adequate percolation space around residential buildings & other structures as appropriate? I humbly request the experts to enlighten me on the same.
