Methods of Rainwater Harvesting:
Rooftop Rainwater Harvesting: Collecting rainwater from rooftops is a simple and effective method. It involves channelizing rainwater through gutters and downtakes into storage tanks or reservoirs.
Surface Runoff Harvesting: This technique captures rainwater from land surfaces, such as roads and pavements, using contour trenches, or permeable pavements to direct water towards storage systems.
Applications of Harvested Rainwater:
Irrigation
Non-potable Domestic Use
Groundwater Recharge
Emergency Water Supply.
