Permanent decline of groundwater table was observed in some area due to over extraction of groundwater and least natural recharge. Management of groundwater is needed for sustainable use of water for irrigation, drinking and other purposes. The paper aims to assess the trend of rainfall and groundwater level and recommend the groundwater level management option. Rainfall and Groundwater level data have been collected from the Barind Multipurpose Development Authority (BMDA). The data are checked for quality and consistency and then processed in the required format. After checking and analyzing the data, hydrographs are drawn and found the trend. Results show that annual average rainfall is lower than the country average; gradual decreasing trend in groundwater level; MAR technique increases the GWL reducing the declining trend. Though BMDA has taken so many initiatives to reduce the stress on groundwater through surface water augmentation and devising efficient irrigation management system, groundwater table is going down day by day due to the excessive exploitation of groundwater. MAR technique is a suitable option to reverse the declining trend of groundwater level. So, research and study are necessary to design and modify MAR structure for sustainable management of groundwater table in Barind area.
