Former MP Harsha Kumar alleged that the sub-standard material is being used in the construction of Polavaram Project. He came down heavily on central and state governments for their negligent attitude towards Polavaram Project. Harsha Kumar has stated that East and West Godavari districts will face threat by increasing the height of cofferdam to 41 feet. He warned cities like Kakinada and Bhimavaram will submerge in water if there is a breach in cofferdam. He asked why CWC engineers did not appreciate the ongoing works of Polavaram.
