Ground Water is a Precious National Resource - Preserve it, Protect it and Don't Pollute it.

State Profile 
Ground Water Scenario of Orissa

Area (



Five physiographic units

  • The Coastal Plains  
  • The Northern Uplands  
  • The Erosional plains of Mahanadi valley
  • The South-Western Hilly Region
  • The Subdued Plateaus


Mainly eight major river basins within the State, whereas the Indravati, Kolab, Machakund sub-basins forms part of Godavari river basin. Most of the major rivers flow in easterly and southeasterly.

Total Districts / Blocks

30 Districts


The State is underlain by diverse rock types ranging in age from Archaean to Recent. The State can be hydrogeologically sub divided into consolidated, semi-consolidated & unconsolidated formations. The consolidated formations include hard crystallines and compact sedimentary rocks whereas semi-consolidated formations include weathered and friable Gondwana sedimentaries and loosely cemented Baripada beds. The unconsolidated formations include laterites and recent alluvium. The yield of tubewells tapping granite gneisse ranges between 10-35 m3/hr whereas other consolidated formations, it ranges between 5-18 m3/hr. The yield of tubewells in semi-consolidated formations range between 20-115 m3/hr.
