Rain water harvesting.

Rain Water Harvesting is the method to collect the rain water when it rains, store that water above ground or charge the underground and use it later. This happens naturally in open rural areas. But this is not possible in metro because the no space is left in our congested city . Reason our city are growing as a concrete jungle.We have left no natural space so that water can be store for further use.
Firstly the question arises that why we need rain water harvesting.As our population is ggrowing aat rapid speed due to this there is a sheer pressure on our resouces especially on land and water. Other reason of mis utilization of water is rapid speed of industralization.Due to above reason we have destroyed our natural lakes and other water bodies.Once they are destroied natural water soaking capability is damaged, which results in drop of water layer.
To encounter these ill effect we should preserve our natural resoure like water.Without water we can't sustain any more.Especially in our country many people do not have have direct acess to water for their daily need rain water harvesting method will be benificial. The water which we receive in form of rain is not been preserved by us and all of it get waste.But if we preserve it can fullfill our need up to some extent depending upon the amount it is preserved.The main benefit will be it will reduce the sheer pressure on natural resources.It is esteem demand of time that goverment should wake up and make rain water harvesting compulsary for all for the benifit of the country.
