Components of Rainwater Harvesting System
Catchment: The surface area where rainwater is collected, such as rooftops or land. Conveyance: Gutters, downspouts, and pipes that carry rainwater from the catchment to storage. Storage: Tanks, cisterns, or barrels used to store rainwater for later use.	Image Source

Types of Rainwater Harvesting Systems
Roof-based systems: Collect rainwater from rooftops and direct it to storage tanks. Surface-based systems: Collect rainwater from open surfaces like lawns or driveways and channel it to storage. Combined systems: Utilize both roof-based and surface-based methods for increased efficiency.	Image Source
