An earthen bund was formed with a composite length of 388M, between two hillocks forming a big reservoir with an impounding capacity of 1.88 TMC (53.24 M.Cum). The Project mainly envisage providing irrigation facilities to an ayacut of 16,000 acres through 2 canals namely Right main canal and left main canal for 17 villages of Udayagiri and Varikuntapadu Mandals of Potti Sri Ramulu Nellore District which is said to be a drought prone area.
The estimate is divided into mainly 3 parts of work. 1. Dam and apurtment. 2. Left main canal 3. Right main canal.
Dam and Apurtment works:-
The earthen bund and the rock toe is damaged at various locations and also the apron & side walls are damaged in the D/s of the spillway. The approach roads to the dam were damaged. Both head sluices are damaged due to this heavy seepage losses are occurring. Hence the head sluices are proposed for reconstruction. Hence modernization of this project is proposed under JICA loan assistance.
In the Dam and Apurtment works, it is proposed to provide repairs to 4 No. radial gates and re construction of 2 head regulators, repairs to rock toe and apron of weir. Approach to regulators and CC road as per Morth on top of earthen bund, electrification etc. is also proposed.
