NTR - TELUGU GANGA PROJECT

❖ Telugu Ganga Project is an Inter State Project formulated to irrigate 5.75 Lakhacres in drought prone areas of Kurnool, Kadapa and Chittoor Districts ofRayalaseema and upland areas of Nellore District in Andhra Pradesh.

By Utilizing 29 TMC of Krishna Flood Water to irrigate 2.75 Lakh

Acres in Kurnool and Kadapa Districts

OBJECTIVE

By utilizing 30 TMC of Pennar Flood Water to irrigate 3.00 Lakh

Acres in Nellore and Chittoor Districts

❖ Conveying 15 TMC of Krishna water to Chennai City for drinking purpose from the contribution of three Krishna River basin States, Maharashtra, Karnataka and erstwhile Andhra Pradesh with 5 TMC from each State.

❖ To generate 33 M.W Power at Velugodu Balancing Reservoir (9M.W), Chennamukkapalli Regulator (15 M.W.) & Kandaleru Reservoir (9M.W.)

BRIEF HISTORY

❖ Due to successive droughts and consequent acute scarcity of drinking waterfor the metropolitan city of Madras, the then Prime Minister of India madehistoric announcement at Madras on 15th Februvary,1976 that the threeKrishna basin states of Maharashtra, Karnataka and the erstwhile combinedState of Andhra Pradesh had agreed to spare 5 TMC each from their respectiveshares of Krishna waters to meet the requirements of Madras City Water supply.

❖ On 14-04-1976, the three Krishna basin States of Maharashtra, Karnataka andthe erstwhile combined State of Andhra Pradesh had agreed to spare 5 TMCeach from their respective shares of Krishna waters to meet the requirements ofMadras City Water supply.

❖ A meeting Convened by the Union Minister ofAgriculture & Irrigation on 27-10-1977 and attended by representatives of allthe four states, it was agreed that the Govt. of TamilNadu shall be permitted todraw not more than 15 TMC in a Water Year from Srisailam Reservoir during theperiod from 1st July to 31st October through an open lined channel.

❖ In the meeting between the Chief Minister of Andhra Pradesh andTmailNadu held on 15-06-1978, it was agreed to commence investigationof the project and to get the progress of investigations monitored by aLiaison Committee.

❖Governent of TamilNadu agreed to share the expenditure on theconstruction, improvements including lining and maintenance of thecomponents specified in schedule “A” and Srisailam Reservoir inaccordance with the guidelines specified in Schedule “B”.

❖ The transmission losses in the water conductor system from SrisailamReservoir to AP-TN border be restricted to 3 TMC in a water year.

❖ The water is to be delivered at the constant rate of 1000 C/s restrictingthe no.of days to limit the total supply at border to

8 TMC from July to October and4 TMC from January to April

❖ The Liaison Committee to monitor the progress in the implementationof the scheme and also ensure effective co-ordination between the twoGovernments after completion of the scheme.
