Geophysical survey for Rainwater Harvesting, a number of years of experience and technical knowledge we are able to provide you the most suitable locations to drill a Borewell on your site. By using technically advanced equipment like Resistivity meters & Electromagnetic (EM) VLF instruments we provide high quality service with excellent execution. Before any Rainwater Harvesting System construction is done, we help you in identifying the nature of Soil Structure & what is the actual Depth to recharge Rainwater.

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

CGWA Clearance Central Ground Water Board (CGWB) . Statement indicating position of pending cases received for NOC for ground water withdrawal. Statement showing list of project proposals to whom NOC for ground water withdrawal has been issued. The annual replenishable ground water resources availability plays an important role in defining the guidelines. The latest assessment of the state wise ground water resources as on 31.03.2009 is available at the Central Ground Water Board . As per the ground water resource estimates of 2009, out of the 5842 assessment units (Blocks, Mandals, Talukas, districts), 802 over-exploited units, 169 critical units, 523 semi-critical units, 4277 safe units and 71 saline units have been identified across the country by Central Ground Water Board. The Annual replenishable ground water resources have been estimated as 431 Billion Cubic Meters (bcm). The Net Ground Water Availability is 396 bcm and the overall stage of ground water development of the country is 61%. Therefore, prior permission/NOC from CGWA has to be obtained before construction of any Groundwater abstraction structure viz. Tube wells, Bore wells, Dug wells etc. Allegiance can offers its client the following services: Examining the area of the groundwater against availability Water requirement Availability of aquifer A Shallow aquifer B Deeper aquifer Status of the groundwater development of the area Preparation of proposal for augmentation of groundwater abstraction Preparation and implementation of water conservation measures Facilitation for obtaining NOC from CGWA, New Delhi
