The Central Ground Water Board is the National apex organisation with responsibilities to carry out scientific surveys, exploration, monitoring of development, management and regulation of country’s vast ground water resources for irrigation, drinking, domestic and industrial needs. Mandate of the Board – “Develop and disseminate technologies, monitor and implement national policies for the scientific and sustainable development and management of India’s ground water resources, including their exploration, assessment, conservation, augmentation, protection from pollution and distribution, based on principles of economic and ecological efficiency and equity.” The main activities of the Board are hydrogeological surveys, exploration, nationwide monitoring of the behaviour of water table and water quality, assessment and monitoring of development and management of ground water resources. The data generated from these investigations provide a scientific base for user agencies. Besides advising states and other user agencies on planning and management of ground water development schemes, Board is also taking up special studies on research and development, conjunctive use of surface and ground water, artificial recharge, water balance, and pollution, etc. It also organises various training courses for personnel of its own, as well as for other Central, State Govt. Organisations and Public Undertakings besides developing personnel from countries. Established in 1954, CGWB functions under the Ministry of Water Resources, Government of India. The Board is headed by a Chairman and has 4 Members. It has 18 regional offices headed by Regional Directors which function in different State capitals. There are 17 Drilling divisions and 10 unit offices. It has about 5,000 scientific and engineering personnel to meet out to the responsibilities. The West Central Region (WCR) with its Headquarters at Ahmedabad has jurisdiction over the state of Gujarat and the UT of Daman & Diu .The programme is oriented in close co-ordination with state government organizations namely Gujarat Water Resources Development Corporation (GWRDC) and Gujarat Water Supply and Sewerage Board (GWSSB) and U.T. administration. Hydrogeological studies in the state of Gujarat commenced in early fifties by the scientists of Geological Survey of India (GSI). The groundwater survey and exploration gained momentum with the creation of a separate wing of GSI in 1953. The Exploratory Tubewells Organization (ETO) was created in 1954 to take up drilling and construction of exploratory tubewells in the country. Groundwater division of GSI in collaboration with ETO launched a massive programme of groundwater exploration with technical and financial assistance of USA under Technical Cooperation Mission (TCM). Under this mission, and subsequently by ETO and GSI, large areas of Gujarat, mainly in soft sedimentary formations, were taken up for surveys and exploration. In 1970, ETO was renamed as CGWB and in 1972 the groundwater wing of GSI merged with CGWB. The Gujarat State and UT of Daman & Diu were included under the jurisdiction of District Unit located at Ahmedabad, which functioned under Western Region, Jaipur. The engineering wing (Div.I) at Ahmedabad continued to look after drilling operations. Subsequently, the Ahmedabad Unit Office was upgraded to the status of a Regional Office in 1986.
