MANGALORE: Will Mangalore emulate Bangalore and Chennai in stopping the road digging by adopting trench-less digging technique?

“Idea is good. But it is very expensive,” said in-charge Commissioner of Mangalore City Corporation J.R. Lobo. He agreed that any amount of finesse in relaying the road after it was dug up would not restore their original shape.


A machine placed on a roadside digs tunnels a few feet below the surface in Bangalore and Chennai to minimise the area of road digging on main roads.


Mr. Lobo said it was easier in Bangalore because of the large number of trenches that were needed to be dug in big cities. Private entrepreneurs possessing such machines might not find it lucrative to work with them in places such as Mangalore. “It should be feasible for him as well,” Mr. Lobo said. He said his past experience had suggested that the trench-less digging was 25 times more expensive than the traditional digging and restoration put together. However, he agreed to consider this as an option for future.


The Mangalore City Corporation can consider keeping the public informed as it has the case with some of the local administrations in the U.K.

The County Council of West Sussex has recognised the right of citizens to be aware of road digging in their area. The Council’s website says: “It is our aim to ensure that everyone is kept informed of who’s digging up the road and why, particularly those who are immediately affected by the work. In the case of road work being carried out by Public Utilities, we will not always have full details, but will be able to provide a contact that can give further information.” It explains, how and who should be informed “up to two weeks before the work takes place…” They will have to know what’s being done, when the work will start, how long is it expected to last, and the hours of work on the site. Can something like this happen in Mangalore? Mr. Lobo said people had the right to know this information and that the corporation would examine the possibility of asking those who took permission to dig the road to put up a board containing the information.
