Hailing Bal Thackeray's role in the construction of Middle Vaitarna dam in Maharashtra's Thane district, Shiv Sena legislator Ravindra Waikar on Tuesday demanded that the project be rechristened after the late Sena Supremo.

"The Vaitarna river has three dams. The upper dam was constructed by Maharashtra government and lower one by Municipal Corporation of Greater Mumbai. An engineer named Modak had built the lower dam and thus the dam is known as Modak Sagar," Waikar told reporters here.
