What a difference in the progress of the Polavaram project works! One can clearly distinguish it from the pace of work during the erstwhile government. During the regime of former CM Chandrababu Naidu, the works were just an illusion of graphics. 



But now, things changed completely. The illusion became a visible reality now. The determination of serving CM Jagan Mohan Reddy supplemented with an effective action plan gave momentum to the project works, which have now reached a critical stage. 

Given the fast pace of the works in regard to the spillway, the project can even brave the Godavari floods and go ahead with the works without much tension. 

Chief Minister Jagan Mohan Reddy is not leaving any stone unturned to complete the Polavaram project, a dream project for Andhra people. Going by the vision of CM Jagan, MEIL has also increased the pace of the construction works and already completed the construction of Piers for 52 blocks in the spillway. The installation of the  Girders indicated the completion of the major works of Spill Channel. A total of 48 gates would be installed here. By the time Megha Engineering took up this project, works related to Piers were in different stages. Now they are completed up to 52 meters of height. Compared to laying concrete on flat land, concreting narrow Piers is a complex process. If it is for a multi-purpose project like Polavaram, it is much more complicated as it requires following stringent construction rules. With its proven mettle, it is completing this work without any hiccups.

Heavy gates were installed for the Polavaram project with heavy hydraulic system gates.   There are only two projects in the world that have these hydraulic system gates. Earlier, China constructed the Three Gorges Dam, making Polavarm the second project to equip heavy hydraulic system gates. These are the first heaviest gates with the hydraulic system in the world. To make this happen by this year-end, the process of placing the Girders on the spillway has begun on Monday. After a traditional Pooja performed, the Girders placed on the 45 and 46 blocks of the spillway. After completion of placing Girders on the spillway, the hydraulic gates will be installed. With this process, the floods will not affect the progress of project work. The existing reservoirs in the state have the electro-mechanical gates. The operating cost is very high as the iron ropes to be changed frequently. To overcome this, the construction company is planning to install cost-effective and most advanced hydraulic gates in the Polavaram project.

Around 1.11 lakh Cum of concrete work in the Spill channel is expected to be completed by the end of June. It could also complete 1.41 lakh Cum in Spillway, 3.10 lakh Cum of concrete work in the hydroelectric project, along with 10.64 lakh Cum of earthwork, 1.14 lakh Cum of stone crushing and 10.86 lakh Cum of Vibro-compaction works. With all this, MEIL is confidently moving ahead with a firm determination to complete all the project works within the expected time frame.

Polavaram multi-purpose project is being constructed to provide irrigation water for 7.2 lakh acres, 960 MWs of power generation, transporting 80 TMCs of Godavari water to Krishna River above Prakasham Barrage, providing 23.44 TMCs of drinking water to Vishakapatnam city and also 28.5 lakh people belonging to 540 villages. On this front, the ongoing works like completion of the spillway, earth-cum-rock fill dam and other ancillary works, construction of hydro-electric project and cofferdam at upper and lower reach, are very critical for this project
