Bengaluru Floods Again: Why the 'Silicon Valley of India' Sinks Despite Its High Altitude

Bengaluru, India's IT capital situated 3,000 feet above sea level, has once again been brought to its knees by incessant pre-monsoon rains. The city has seen record-breaking rains—130 mm in 12 hours—resulting in large-scale flooding, traffic gridlocks, and tragic fatalities over the last week. In spite of being at high elevation, the city's long-standing flooding reveals deep-seated urban issues.

Key Highlights
Record Rainfall and Widespread Impact

In a span of 12 hours, Bengaluru soaked up 130 mm of rain, a record high since 2011, inundating more than 500 houses and resulting in three deaths, including a 12-year-old boy and a woman who was crushed by a falling wall.

Over 20 lakes overflowed their banks, with large localities such as Koramangala, BTM Layout, Yelahanka, and Mahadevapura getting inundated. Public transport was paralyzed, and rescue boats were put into action in the worst-hit localities.

Why Bengaluru Floods Despite Its Elevation

Historically, Bengaluru possessed a system of more than 1,400 lakes and natural valleys that carried away excess water. Unrestrained urbanization, particularly after the IT boom, has resulted in uncontrolled encroachment of lake beds and clogged natural drainage channels.

Today, there are only around 190 lakes left, and stormwater drains are incomplete or clogged, with fewer than 60% of them having retaining walls. Major flood-mitigation projects are still on the backburner.

Government Response and Current Actions

Deputy Chief Minister DK Shivakumar stated that 70% of the city's 210 trouble points vulnerable to flooding have been dealt with, with 197 km of new stormwater drains built and ₹2,000 crore set aside for additional work.

Still, 41 key hotspots identified by traffic police are yet to be worked upon, and the city's infrastructure still can't keep pace with the magnitude of the issue.

Forecast and Alerts

The India Meteorological Department has released an orange alert for Bengaluru, predicting further heavy rain and thunderstorms in the next five days.

The Bottom Line
Bengaluru's flooding is a man-made disaster, based on decades of bad urban planning, ignored drainage, and uncontrolled construction. Although authorities vow long-term fixes, the city's residents have to endure an every-year monsoon nightmare.
