Abstract: The Malwa Plateau, covering the western part of Madhya Pradesh north of the Narmada Valley mostly covered by the basaltic lava flows of Deccan Trap igneous activity.This plateau characterized by flat topped hills and step like terraces. The groundwater which encountered in basaltic rocks generally occurs in the joints and fissures. These structures mostly provide the secondary porosity and permeability.The Deccan Traps formations can be tapped by dug-cum-bore and drilled wells.It is observed that the yield increased by 5-10 times when 10-15m bores extending down to the lower vesicular zone are drilled at the base of dug wells.Yields of 400-600 m³/d can be obtained in this way.
