Bengaluru, the capital city of Karnataka, often experiences urban flooding during the monsoon season, especially between June and September. While not a coastal city, its topography, rapid
Stormwater systems of today need to take into consideration rising rainfall, population growth, and suburbanisation. Yet, most Indian cities continue to employ narrow, choked, and frequently illegal or unofficial drains
Flood-prone areas in Bangalore include Bellandur, HSR Layout, Koramangala, Sarjapur Road, Whitefield, KR Puram, and parts of Indiranagar, especially those near lakes and stormwater drains.
Bangalore sits on a plateau, but unplanned construction, shrinking water bodies, encroachment of rajakaluves (stormwater drains), and poor drainage maintenance have led to frequent flooding in many areas.
The BBMP deploys mobile water pumps, clears stormwater drains, and operates a 24x7 control room to respond to complaints. Citizens can call the BBMP helpline at 2266 0000 for assistance.
In severe cases, offices may advise work-from-home and schools may declare holidays depending on BBMP warnings and IMD alerts for heavy to very heavy rainfall.
