The main reasons for decline in ground water levels in NCT of Delhi include increasing ground water withdrawal for various purposes especially in areas where piped water supply is inadequate and rapid pace of urbanization resulting in reduced natural recharge to aquifers.

 

Action taken by the Government to check depletion of ground water in Delhi are as under:

 

·   Central Ground Water Authority (CGWA) has notified Yamuna flood plain, South and South West Districts of Delhi for regulation of ground water development and management.

·   CGWA has directed  all the Residential  Group Housing Societies/ Institutions/Schools/ Hotels/ Industrial Establishments falling in the over-exploited and critical areas (Except in the water logged areas) in the country to adopt Roof Top Rain Water harvesting systems in their premises.

·     CGWA has directed to Heads of Central Road Research Institute, National Highway Authority of India, Central Public Works Department,  Railway Board, Sports Authority, Airports Authority of India, Civil Aviation, Youth Affairs & Sports to implement the Scheme of Ground Water Recharge  along all National/State Highways and other roads,  railway tracks and other establishments of Railways,  all stadia and airports.

·     CGWB has implemented 17 demonstrative recharge projects under the central sector scheme of ‘Study of Recharge to Ground Water’.

·     CGWB has also displayed bilingual hoardings at prominent Metro Stations for promoting rain water harvesting.

·     Ministry of Water Resources has circulated the Model Bill to regulate and control development and management of ground water to all the States/ UTs including Delhi.

·     Ministry of Urban Development and Poverty Alleviation, Govt. of India has modified Building Bye-laws (1983) to incorporate mandatory provision of roof top rain water harvesting in new buildings on plots of 100 sq.m. or more in Delhi through storage of rainwater runoff to recharge underground aquifers.    

·     Govt. of NCT Delhi vide its order No. F8(348)/EA/Env/09 dated 31.3.2009 has notified all the districts of NCT for regulation of ground water development.
