Bengaluru: With the monsoon season expected to arrive next month, the Bengaluru North City Corporation (BNCC) has introduced a simple yet potentially life-saving measure to prevent flood-related accidents at underpasses across the city. Citizens approaching flood-prone underpasses during heavy rain will now be able to gauge whether it is safe to enter based on newly painted water-level indicators and warning messages.
Water-Level Markings and Warning System
As part of its monsoon-preparedness drive, BNCC has begun painting water-level markings at underpasses under its jurisdiction. These markings indicate flood levels from one foot to four feet, alongside safety instructions for both motorists and pedestrians. Water levels above two feet have been designated as a danger zone.
The warning reads: “When water level reaches designated danger mark, the underpass shall be deemed unsafe and unfit for pedestrian and vehicular traffic. In case of emergency, contact Bengaluru North City Corporation.”
Background and Rationale
The initiative comes as civic authorities acknowledge that major structural changes to existing underpasses are difficult, particularly with rains round the corner. While drain cleaning and stormwater maintenance are still ongoing, officials believe timely public awareness could help avoid tragedies by discouraging people from entering inundated stretches. In 2023, a software professional lost her life after being trapped in a flooded underpass near KR Circle.
According to BNCC data, the civic body has 33 underpasses within its jurisdiction, of which 28 are identified as flood-prone. Painting work has been completed at 10 underpasses, and work is underway at two more.
Official Statements and Future Plans
BNCC commissioner Pommala Sunil Kumar said the markings are meant to function as an immediate warning system for commuters: “Once water reaches the red mark, traffic police can start barricading the underpass and prevent vehicles from entering.” While the idea may appear simple, such precautionary measures are often overlooked despite their importance during emergencies, he said.
The civic body plans to complete the painting work at all flood-prone underpasses before the monsoon sets in. Additionally, BNCC is coordinating with traffic police to ensure quick response when water levels reach danger marks.
Public Awareness and Safety Tips
Residents are advised to avoid entering underpasses when water levels exceed two feet. In case of emergencies, citizens can contact BNCC helplines. The corporation also urges commuters to follow traffic advisories and not take risks during heavy rains.
