Rainwater Harvesting is the process of collecting and storing rainwater from rooftops or other surfaces for future use. It helps conserve water and reduces dependence on groundwater.
Diagram Explanation
Rainfall – Rain falls on the roof.
Gutters and Downpipe – Water is collected and directed through pipes.
Filter Unit – Removes leaves, dust, and other impurities.
Storage Tank – Clean water is stored for later use.
Recharge Pit/Well – Excess water is allowed to seep into the ground, increasing groundwater levels.
Advantages
Saves water for daily use.
Recharges groundwater.
Reduces water bills.
Prevents flooding and soil erosion.
Eco-friendly and sustainable.
Uses
Gardening
Washing vehicles
Toilet flushing
Cleaning
Drinking (after proper treatment).
