A Rain Water Harvesting Mini Model demonstrates how rainwater can be efficiently collected, filtered, and stored for reuse. The system captures rainwater from rooftops or other catchment areas, passes it through a filtration unit, and stores it in a tank for purposes like irrigation, cleaning, or groundwater recharge. This model is ideal for educational purposes, creating awareness about water conservation.

Parts Used:

1. Catchment Surface – Simulated rooftop or sheet for collecting rainwater
2. PVC/GI Pipes – For directing water to the storage tank
3. Filtration Unit – Gravel, sand, and charcoal layers to remove impurities
4. Storage Tank – Holds filtered water
5. Overflow Pipe – Prevents tank overflow
6. Base Structure – Holds the entire setup for display
