Roof Top Rain Water Harvesting 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. Advantages of Rain Water Harvesting 1. Provides self-sufficiency to your water supply 2. Reduces the cost for pumping of ground water 3. Provides high quality water, soft and low in minerals 4. Improves the quality of ground water through dilution when recharged to ground water 5. Reduces soil erosion in urban areas 6. The rooftop rain water harvesting is less expensive 7. Rainwater harvesting systems are simple which can be adopted by individuals 8. Rooftop rain water harvesting systems are easy to construct, operate and maintain 9. In hilly terrains, rain water harvesting is preferred 10. In saline or coastal areas, rain water provides good quality water and when recharged to ground water, it reduces salinity and also helps in maintaining balance between the fresh-saline water interface 11. In Islands, due to limited extent of fresh water aquifers, rain water harvesting is the most preferred source of water for domestic use 12. In desert, where rain fall is low, rain water harvesting has been providing relief to people

Injection well Technology is the most effective in capturing surface run off both from plain open loose area or from storm line and filtering in two stages by filtering rainwater through 4 stages of filtration through Silt Trap and Injection well. The silt traps takes care of most impurities in the first stage itself, as it has 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and horizontally fixed V wire non clogging SS screen of 500 mm length and 150 mm dia. Rainwater then flows through main Injection well where it flows by gravity through 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and vertically placed V wire non clogging SS screen of 500 mm length and 200 mm dia. on the recharge bore well. Air vent from bore well and main well is kept at center. The main well is designed to do maintenance whenever is required. As such the filtration media only needs cleaning once in a year Silt Trap and Injection well. The best technology to have head pressure by the way of water column to ensure fast recharge of ground water and recover the water levels in Aquifer.

Water Conservation, Ground Water Rejuvenation and Development via Rainwater Management and Harvesting Rainwater through Ponds and Borewell Recharging Structures to Support Increasing Demand of Water for Daily usage for Domestic, Industrial and Agricultural purposes. Water Conservation and Harvesting Structures in Naturally Water Scarce Regions creates Geo-Hydrological Opportunity and Economic Viability. Ponds recharging structure, farm pond, stop Dam, and small pond etc. It is seen that different Geographical Location and unique Geophysical and Hydrological Nature and every situation needs to be addressed, separately, the groundwater recharge capacity of the varies regions may vary depending upon area specific geophysical nature of earth strata. Recharge Wells provide an opportunity to extract sub-surface flow of the region without exploiting the Groundwater reserve.
