Western Railway (WR) has been conducting topographical studies on flooding patterns at several locations in the suburbs. Accordingly, WR authorities have created more underground waterways for quick discharge of accumulated water this monsoon, with five new waterways being constructed this year.

“The topography of major flood-prone areas such as Bandra, Andheri, Mahim, Grant Road, Goregaon, Vasai Road and Virar was studied in detail. Accordingly, customised solutions were devised for each location by adopting modern technology and techniques to put an end to this perennial issue of flooding. One of the techniques includes the construction of additional waterways using micro-tunnelling,” Sumit Thakur, chief public relations officer, WR, said. He added that the technique has been used between Bandra and Khar, Goregaon and Malad, Vasai Road and Nallasopara, and Nallasopara and Virar sections, as well as near culvert No. 79 at Nallasopara (South).
