The civic body's disaster helpline, which has been functioning without a break for 15 years, will be shut for two days for the first time.

In a move to overhaul the system, making it completely new age and technologically equipped, the cell will be shifted to another space in the same building. It will now have live screening of all surveillance cameras put up across the city.

Complaints to the cell range from burst pipelines, potholed roads, fires, building collapses, road cave-ins to terrorist attacks and bomb-blasts.

The helpline number 1916 will be back at 2am on November 25. Mahesh Narvekar, Chief Officer, Disaster Cell, said, "The existing infrastructure remains. What is new is the live screening, which will give realtime information."
