The project recently bagged the Central Board of Irrigation and Power award for speedy execution.
The Polavaram multipurpose irrigation project entered the Guinness Book of World Records today by pouring 32,000 cubic metres of concrete in 24 hours during the work of dam construction, according to Guinness officials present in Andhra Pradesh's Polavaram to record the feat.
Work on the project, being undertaken by the private sector Navayuga Engineering Co Ltd, is being conducted with extraordinary speed to make the dam ready for irrigation purposes by June.
"Concreting for a project of this size normally takes around three years, but at this pace and passion, the dam will be completed by June," Navayuga MD Chinta Sridhar said.
The project had been taken over by Navayuga after the earlier contractor failed to deliver on timelines.
The concrete work to make the dam spillway began at 8 am on Sunday and concluded at the same time today morning.
Chief Minister Chandrababu Naidu visited the project site later in the day.
"The water problem in both north and south Andhra Pradesh will be resolved by the commissioning of this project. Around 2 crore people will get drinking water after it starts," Mr Sridhar said.
The project recently bagged the Central Board of Irrigation and Power (CBIP) award for speedy execution.
Designed to withstand massive floods, the Polavaram spillway is set to have one of the highest discharge capacities in the world at 50 lakh cusecs.
The total storage capacity of the water reservoir is 120,000 million cubic feet (TMC).
The multipurpose project is expected to generate 960 MW of power by end of 2020, Mr Sridhar added.
