The availability of water is the chief necessity to keep alive all living beings. The motive of this center is to investigate the underground water resources for the service of the society so as to solve the problem of drinking water as well as to help increase its availability for irrigation. Geophysical exploration by geo electric method has become the most indispensable tool in recent times for locating ground water throughout the world. In this method, electrical currents are sent below the ground surface at different depths and

resistance offered by the ground is recorded by microprocessor based digital deep resistivity monitor, and the differences in the values of resistance at different depths, nature of various earth material and water are detected. Geoelectric survey is accompanied by hydro geological inventory and geological studies.We are extensively carrying Hydrogeological studies ground water survveys in organised & unorganised sectors. The development of ground water in different areas of the country has not been uniform. Highly intensive development of ground water in certain areas for irrigation, drinking, domestic & industrial uses in the country has resulted in over-exploitation leading to long term decline in ground water levels, and under certain situations deterioration in the quality of ground water.

As per the ground water resource estimates of 2004, out of 5723 assessed units (Blocks, Mandals, Taluks, Districts), 839 over-exploited units, 226 critical units, and 550 semi-critical units have been identified across the country by Central Ground Water Board. So far 43 areas have been notified by CGWA for the purpose of regulation of ground water development.

Therefore, prior NOC from CGWA has to be obtained before construction of any ground water abstraction structure viz. tube wells, dug wells, bore wells, etc. The development of ground water in different areas of the country has not been uniform.

• Therefore, prior NOC from CGWA has to be obtained before construction of any ground water abstraction structure viz. tube wells, dug wells, bore wells, etc. Examining the area of ground water against its availability
• Water requirement
• Availability of aquifer
(A) Shallow aquifer
(B) Deeper aquifer
• Status of ground water development of the area.
• Preparation of proposal for augmentation of ground water abstraction.
• Design, Construction & Implementation of rain water harvesting structure/ turnkey basis.
• Preparation & Implementation of water conservation measures.

CGWA under the MOWR is regulating the withdrawal of ground water in over exploited, critical and semi-critical blocks. Perior permission is required for ground water withdrawal by new as well as existing industries. Industries / Infrastructure projects seeking NOC for withdrawal of ground water in Semi-critical, Critical and Over-exploited areas are required to submit their application in the prescribed proforma either to the Office of the Regional Director, CGWB of the concerned State, or to Member Secretary, CGWA, New Delhi. The completed application submitted to Member Secretary, CGWA, New Delhi is referred to the concerned Regional Director for his comments which he is required to submit in the evaluation proforma.

All Industries seeking NOC for ground water abstraction are required to submit a referral letter from statutory organizations such as State Pollution Control Boards, Ministry of Environment and Forests, Bureau of Indian Standards, etc., for processing of their cases.

All Industries/ projects are required to submit detail designs for Rain Water Harvesting which is mandatory for areas falling in all critical blocks. Whenever permission/ NOC for ground water withdrawal is accorded by CGWA, a mandatory clause for Rain Water Harvesting and Artificial Recharge to ground water by the Industry/ Infrastructure projects is included. We are extensively carrying out the detailed studies for the CGWA Clearances.
