Rain is fresh and soft water available at no cost. We get millions of litres of water every year across the world. Rain is the fundamental source of water that helps raise water level in all our existing sources of water. Rivers, Dams, Lakes get filled and even aquifer below get rainwater through natural process of percolation. Rainwater in the natural form is the form of water which is soft in nature and doesn't contain any impurity. Rainwater if captured, collected, filtered and stored, is the best way to avert crisis of water. Rainfall on roof, surface,river,garden, loose soil, paved areas is fresh source of water if not collected it flows and creates water logging or flooding that results in death of thousands of lives, damage to crops, prospeities, homes and animals. It is time to understand the resource in modern context. We need to fill the gap between water scaricity and flooding. It is the most sensible thing to do in today's context. More over rainwater which is allowed to flow in oceans is not a good sign; fresh water then becomes saline water which is good for nothing.
Our new habitats, satellite colonies, integrated townships, industries, institutions etc. are developing mostly in outskirts of main cities; not connected with municipal water grid. These habitats depend only on ground waterthrough bore wells.
A decentralised approach to make these habitats water sufficient, is harvesting at a point of usage. "Catch the rain where it falls and go closer to it's resource". Rooftop rainwater harvesting in the most efficient, effective and economical manner is the first step towards being water secure for a better tomorrow.
