GROUND WATER RESOURCES OF PUNJAB STATE (As on 31st March, 2017) CENTRAL GROUND WATER BOARD WATER RESOURCES & ENVIRONMENT NORTH WESTERN REGION DIRECTORATE, PUNJAB CHANDIGARH WATER RESOURCES DEPARTMENT MOHALI OCTOBER, 2018 i GROUND WATER RESOURCES OF PUNJAB STATE (As on 31st March, 2017) Prepared by WATER RESOURCES & ENVIRONMENT DIRECTORATE, WATER RESOURCES DEPARTMENT, PUNJAB, MOHALI and CENTRAL GROUND WATER BOARD NORTH WESTERN REGION CHANDIGARH OCTOBER, 2018 ii FOREWORD One of the prime requisites for self-reliance and development of any state is the optimal development of its Water Resources. Ground Water being easily accessible, less expensive, more dependable and comparatively low in pollution has its merits. In order to develop this precious natural resource in a judicious and equitable manner, it is essential to have knowledge of its availability, present withdrawal and future scope of its development. The present ground water assessment report has been computed by the officers & officials of the Water Resources & Environment Directorate, Water Resources Department Punjab, along with Department of Agriculture & Farmer’s Welfare and Punjab Water Resources Management and Development Corporation Limited on the basis of latest guidelines by the Ground Water Resource Estimation Committee (GEC 2015), Government of India,. The report gives details on total annual recharge to ground water, its present draft and scope for future block-wise development. The present ground water development in the state is 165% as on March 2017. Out of 138 blocks of the state taken for study, 109 blocks are “Over-exploited”, 2 blocks are “Critical”, 5 blocks are “Semi-critical” and 22 blocks are in “Safe” category. There is an urgent need to recharge ground water in the over-exploited blocks and develop available shallow ground water in the safe blocks to avoid water logging in the foreseeable future. The irrigation policy also needs review vis-a-vis prevailing hydrogeological scenario. I would like to appreciate the efforts regarding excellent data collection by the officers/officials of Water Resources and Environment Directorate, Mohali through their superb network and skilled manpower, which is the main support for this whole exercise especially Shri Atul Kumar Sood, Senior Geophysicist, Sh. Suresh Narang, Senior Hydrologist, Sh. Vasu Sachdeva, Junior Hydrologist, Sh. Ashish Swaroop, Junior Geologist, Sh. Sanjeev Bansal, STA and Sh. Karamjeet Singh, Draftsman under the able guidance of Sh. Narinder Kumar Jain, Director, to complete the task in the most comprehensive and logical manner in a very short span of time. I would like to place on record the commendable efforts of Shri S.K. Mohiddin, Senior Hydrogeologist and Sh. M.L. Angurala, Senior Hydrogeologist of the Central Ground Water Board for their contribution in preparation of this report. I personally feel that this report will be of immense use to the planners, administrators and agencies engaged in the development and regulation of ground water resources of the state.
