A rainwater harvesting system is a method used to collect and store rainwater for future use. This system typically involves a network of gutters and downspouts that direct rainwater from rooftops into storage tanks or barrels. By capturing this natural resource, households and communities can reduce their reliance on traditional water sources, especially in areas where water is scarce. Using harvested rainwater can benefit gardens, lawns, and even indoor plumbing. It helps conserve water and can lower utility bills. Additionally, this sustainable practice supports the environment by reducing stormwater runoff, which can lead to erosion and pollution in local waterways.
