What is Roof Top Rain Water Harvesting
Rooftop Rain Water Harvesting is the technique through which rain water is
captured from the roof catchments and stored in reservoirs. Harvested rain water
can be stored in sub-surface ground water reservoir by adopting artificial
recharge techniques to meet the household needs through storage in tanks.
The Main Objective of rooftop rain water harvesting is to make water available for
future use. Capturing and storing rain water for use is particularly important in
dryland, hilly, urban and coastal areas. In alluvial areas energy saving for 1m.
rise in ground water level is around 0.40 kilo watt per hour.
Need for Rooftop Rain Water Harvesting
1. To meet the ever increasing demand for water
2. To reduce the runoff which chokes storm drains
3. To avoid flooding of roads
4. To augment the ground water storage and control decline of water levels
5. To reduce ground water pollution
6. To improve the quality of ground water
7. To reduce the soil erosion
8. To supplement domestic water requirement during summer, drought etc.
