Stormwater harvesting can be beneficial financially, environmentally, and practically. By capturing and reusing rainwater runoff, it helps reduce the demand on traditional water supplies, which is especially valuable in areas facing water scarcity. It also plays an important role in managing urban flooding by slowing down and storing excess runoff during heavy rains.
This helps prevent erosion, property damage, and overloading of stormwater infrastructure. Harvesting stormwater can improve the health of local waterways by reducing the volume of polluted runoff entering rivers, lakes, and coastal areas. From an economic perspective, using harvested stormwater for irrigation, toilet flushing, or industrial purposes can lower water bills and operating costs.
