 In 2007, on the recommendations of the International Water Management Institute, the Indian government allocated to fund dug-well recharge projects (a dug-well is a wide, shallow well, often lined with concrete) in 100 districts within seven states where water stored in hard-rock aquifers had been over-exploited.Another environmental issue is the disposal of waste through the water flux such as dairy farms, industrial, and urban runoff.Wetlands help maintain the level of the water table and exert control on the hydraulic head.
