Rainwater harvesting is the process of collecting and storing rainwater for future use. This method involves capturing rain as it falls on rooftops or other surfaces and directing it into storage tanks or barrels. By using simple systems, households can reduce their reliance on municipal water supplies and save money on water bills. This practice is especially beneficial in areas with limited water resources or during dry seasons. Collected rainwater can be used for various purposes, such as irrigating gardens, flushing toilets, or even drinking, if properly filtered. Overall, rainwater harvesting promotes sustainability and helps conserve precious water resources.
