The plan was incorporated to provide the underground sewer line in Chithra, Uthira Veedhis and Adayavalanjan in Srirangam as the network has to run across narrow strips of land between the rear side of houses and the ramparts of the temple.
Following a technical study it was felt that the vibration that would be caused by micro tunnelling could possibly damage the ramparts. It was felt that the move could be taken up only after a pilot project, but sources told local press that the cost of such a project would be too expensive.
