Availability of Surface and Ground Water
Central Water Commission has assessed the average annual water availability in the country as 1869 Billion Cubic Meters (BCM). However, the utilizable water resources, considering topographic, hydrological and other constraints, has been estimated to be about 1123 BCM comprising 690 BCM of surface water and 433 BCM of replenishable ground water. With a view to augmenting the water resources for utilization for various purposes, viz. irrigation, domestic, industrial etc., several measures are undertaken by the respective State Governments which, inter-alia, include conservation of water resources through reservoir, traditional water bodies, rain water harvesting and artificial recharge of ground water. Ministry of Water Resources, River Development and Ganga Rejuvenation provides technical and financial assistance to the State Governments through various schemes and programmes namely Accelerated Irrigation Benefits Programme (AIBP), and Repair, Renovation and Restoration (RRR) of Water Bodies etc. Further, Ministry of Drinking Water and Sanitation and Ministry of Urban Development supplement the efforts of the State Governments in providing drinking water to the rural and urban areas respectively under various schemes and programmes. This was stated by Union Minister of State for Water Resources, River Development and Ganga Rejuvenation Shri Santosh Kumar Gangwar in a written reply in Lok Sabha today.
