Rainwater harvesting, also known as rainwater collection, rainwater catchment and rain capture, is an age-old method of collecting, storing and recycling natural rainwater to supplement water supply. Based on traditional practices such as collecting in rain barrels and rainwater cisterns, today’s rainwater harvesting systems range from simple rain chain and rain barrel collection to sophisticated networks.
