Hydrogeology

Major water bearing formations are weathered, jointed & fractured rocks of Proterozoic age where ground water occurs under water table conditions. Water bearing fractures generally occur within 100 m depth. The semi-consolidated formations (Gondwanas) are another water bearing formations with weathered sandstone and lime stone forming good aquifers. The unconsolidated sediments including alluvium and laterite are also water-yielding medium.
