The Central Ground Water Board (CGWB) under the Ministry of Water Resources has reported that decline in ground water levels in an area is a cumulative effect of ground water withdrawal for all purposes including domestic, industrial as well as agricultural sectors. As per assessment carried out by CGWB in association with the State Ground Water Departments, the share of agriculture in total ground water used in the country is 92%. Remaining 8% is used in domestic and industrial sectors.

However, the Ministry of Water Resources has circulated a Model Bill on Regulation and Control of the Development and Management of Ground Water to the States/Union Territories for enactment of suitable legislation on the lines of the Model Bill. The ground water legislation has been enacted by 11 States/Union Territories viz. Andhra Pradesh, Goa, Tamil Nadu, Lakshadweep, Kerala, Pondicherry, West Bengal, Himachal Pradesh, Bihar, Chandigarh and Dadra and Nagar Haveli. 19 States/UTs are in the process of enactment of legislation. Remaining States/UTs have also been requested to enact similar legislation.

This information was given by the Minister of State for Water Resources, Shri Vincent H. Pala in a written reply in the Rajya Sabha today.
