Usage of Rain Water Harvesting & Its Advantages 2021 Rainwater harvesting is a technology that collects rainwater, then stores and purifies it for future use. The practice of this method has been discovered in ancient times, but its benefits and cost-effectiveness have helped many industries and households to use rainwater effectively even in modern times. The rainwater collection process is very simple because it involves collecting rainwater in natural reservoirs or constructed water tanks. Rainwater is usually pure. However, certain particles can challenge the quality of the water. Therefore, it is very important to collect rainwater from an impervious surface and store it in a tank for purification in order to prepare it for final consumption.
Within the framework of a project launched in 2001, Chennai, Tamil Nadu, India, adopted rainwater harvesting. This initiative has forced all households in rural areas to install rainwater harvesting systems to avoid depletion of groundwater. After five years of implementation, Chennai water level rose by 5%, and many other states were later persuaded to adopt rainwater harvesting technology to avoid many of the challenges related to water scarcity. From the past few years, it is obvious that many county-level countries are facing the huge challenge of water shortage. Many cities in India have also experienced severe water shortages, causing citizens to pay huge fees for safe drinking water. This shortage will cause many problems, such as depletion of groundwater,
