Burla: The Hirakud dam at Burla in Sambalpur district is now out of danger, according to the preliminary report of the underwater survey conducted recently.
This was informed by Hirakud dam chief engineer Harmohan Pradhan today. He said the report received from the Central Soil and Material Research Station (CSMRS) on August 22 shows that cracks have developed at six places of the dam’s left spillway. The cracks would be fixed through the dripping method. However, the left spillway and the power dam are now safe, he added.
Pradhan further said the report on the condition of the right spillway of the dam is yet to be received.
The survey work was conducted through a remote operated vehicle (ROV) with a state-of-the-art underwater camera, which receives instructions from the control room, inside a vehicle placed on the top of the dam and changes its direction in the water and takes underwater photos of the upstream face of the dam, including the sluice barrel.
The survey team would submit its report to the state Water Resources department.
