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

State Profile
Ground Water Scenario of Telangana 

Area (Sq. km)



Deccan Plateau


The State is drained by two major perennial rivers viz. Godavari and Krishna with several other rivers of lesser significance


Out of gross irrigated area of 29,98,798 Ha, area irrigated by ground water is 21,10,959 Ha ( 70.4%)  surface water is 8,09,111 Ha ( 27%). 


Varies from 732 mm in Mahabubnagar district to 1121 mm in Adilabad district. It increases from less than 800 mm in south-west part of the state to more than 1200 mm in north and north-east part of the state.  The mean annual rainfall of the state is 923 mm of which southwest monsoon season      (June-September) contributes about 80% of the annual rainfall and northeast monsoon season contributes 13% of the annual rainfall.

Telangana is characterized by various geological formations ranging in age from Archaean to Recent.  Nearly 80 percent of the State is underlain by hard rock formations consisting of granites, gneisses, metamorphics and intrusives (Archaeans), Precambrian quartzites, shales and limestones (Cuddapahs & Kurnools), Mesozoic Deccan Trap basalts etc., while the remaining area is underlain by Gondwana sedimentaries and Sub Recent-Recent alluvium. The occurrence and movement of ground water in hard rocks is chiefly controlled by thickness of weathering and structural features like fractures and solution cavities. In general, the depth of weathering varies from 5 to 20 m and occassionally upto 40 m.  Ground water is mostly developed by means of shallow-deep bore wells ranging in depth down to 100 m, occasionally even beyond 100 m with discharges generally ranging from 2-5 lps. The semi-consolidated formations of Gondwanas comprising sandstones, shales, siltstones, conglomerates form thick and multi aquifer systems under confining conditions. The aquifers are often prolific with discharges varying upto as high as 48 lps.
