Rainwater harvesting systems are designed to collect, store, and distribute rainwater for a variety of uses. These systems can be used to supplement a home's water supply, reduce stormwater runoff, and provide water for landscaping and irrigation. Rainwater harvesting systems can be as simple as a
Rainwater harvesting (RWH) is the collection and storage of rainwater, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other area surfaces for storage and subsequent reuse. Its uses include watering gardens, livestock, irrigation, domestic use with proper treatment, and domestic heating. The harvested water can also be used for long-term storage or groundwater recharge.
