GALERU NAGARI SUJALA SRAVANTHI PROJECT
Preamble
The GaleruNagariSujalaSravanthi Project was conceived by the Govt. of Andhra Pradesh in G.O.Ms.No.236, dtd:22-9-88 to take up GNSS. Project. The Project is envisaged to provide Irrigation facilities to an extent of 2,60,000Acres (1,55,000Acres in Kadapa Dist., 1,03,500Acres in Chittoor Dist. And 1,500Acres in Nellore Dist.) and also to provide drinking water facilities to 5,00,000 people. It also envisages drawal of 38TMC flood water of Krishna River from the foreshore of Srisailam Reservoir during the period from August to November.
Administrative approval was accorded for Rs.2189.26Crores by the Govt. of A.P. for Phase-II of GNSS. Vide G.O.Ms.No.185, I&CAD. (Major.IRR.VI) Dept., Dtd:15-10-2005. Revised Administrative approval was accorded for Rs.2525.91Crores vide G.O.Ms.No.50, I&CAD.(MajlIRR.VI) Dept., Dtd:25-03-2008.
In view of the large magnitude of the project and to derive early benefits, the project was taken up in two phases.
The works are entrusted in 14 Packages under G.N.S.S. Phase-II. Among 14 Packages, 7 Package works, i.e., from Package No.8/06 to 14/06 were entrusted to TGP & GNSS. Circle, Srikalahasti. One Package work, i.e., Package No.8/06, comes under Kadapa District and 6 Packages i.e., Package No.9/06 to Package No.14/06 works come under Chittoor District.
