Roof Top Rain Water Harvesting

                               The 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.

1. Need for Rooftop Rain Water Harvesting

        1. To meet the ever increasing demand for water

        2. To reduce the runoff which chokes the 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.

                  

Rain water from roof top sheet collected in the chamber         Rain water harvesting pond constructed near guest house Lake1 with 100MLD  near Shiva temple in the KLS VDIT      Lake 2 with 100MLD  near boy’s hostel in the KLS VDIT camp

Conclusion

Because the rain water harvesting as well as the as the 2 lakes present in the VDIT CAMPUS the 7 bore wells are recharged periodically. Hence there is no water scarcity in the campus even during the summer.
