The water reaches our homes easily. But, do you know, from where and how water comes? We get it from sources like rivers, lakes, wells, and streams. But the water doesn’t come directly to our home from these sources. The water is purified via pumping stations and a water purification plant.

Have you ever asked your mother as to why she dries the wet clothes outside on the balcony or terrace? During the daytime, all the air surrounding gets heated. This warm air provides heat for the evaporation of water. As a result, water vapor gets continuously added to the air. Soon, the water disappears from wet clothes as they dry up.

Do you know how clouds are formed? During the day, the sun heats up the ocean surface, causing water to evaporate. Moreover, the water inside the plants also evaporates. This vapor rises up in the atmosphere and condenses to form tiny water droplets that form the cloud.

Rain is good for the earth and living organisms on it. We enjoy it when it rains! Right? But more is not always merrier. It can even cause a lot of destruction. So, what if it rains heavily? Heavy rains may lead to a rise in the level of water in rivers, lakes, and ponds. The water may then flood the neighboring areas. The crop fields, forests, villages, and cities all get submerged in water.

The basic idea behind rainwater harvesting is “Catching, collecting and storing the water where it falls”. Rainwater harvesting is a technique of collecting and storing rainwater into natural reservoirs or tanks. One of the methods of rainwater harvesting is rooftop harvesting.
