Rainwater harvesting systems are methods used to collect and store rainwater for later use. These systems typically involve capturing rainwater from rooftops or other surfaces, directing it through gutters and downspouts into storage tanks or cisterns. This collected water can be used for various purposes, such as irrigation, flushing toilets, or even drinking, depending on the treatment methods applied. Implementing rainwater harvesting can help reduce reliance on traditional water sources, conserve water, and lower utility bills. Additionally, it can mitigate stormwater runoff, which can lead to flooding and water pollution. Overall, these systems promote sustainable water management practices in communities.
