While Bengaluru often faces severe flooding during the monsoon, an innovative rediscovery by Captain Santhosh Kumar has turned the tide. By tracing century-old drainage channels using maps from 1923, he uncovered buried waterways and helped restore natural water flow, keeping his community dry when neighboring areas were underwater.
- Blocked drains, not rain, cause Bengaluru’s urban floods
- 1923 maps revealed lost waterways and encroachments
- Restoration of lakes and drains prevents flooding in local areas
What happened
Every monsoon season, Bengaluru faces heavy flooding, but Captain Santhosh Kumar observed a puzzling detail: while roads became submerged, the city’s lakes remained largely dry. Investigating further, he discovered that the challenge wasn’t the volume of rain but the obstruction of stormwater drains over many decades due to blockages, burial, and encroachments.
Using British-era maps from 1923, Kumar traced the routes of once-functioning drainage channels and identified neglected waterways beneath the city. His work led to unearthing a 4-kilometer buried waterway and contributed to the revival of 14 ancient lakes. When heavy rains hit next, his own neighborhood stayed dry while surrounding localities were flooded.
Why it feels good
This story highlights how reexamining historical urban infrastructure can offer practical, sustainable solutions to modern challenges. Instead of relying solely on new technology or expensive projects, the rediscovery and restoration of natural drainage systems proves to be an effective flood mitigation strategy.
Captain Kumar’s efforts demonstrate the power of local initiative, environmental stewardship, and respecting nature’s original design. It brings hope that other cities facing similar problems can learn from Bengaluru’s approach and protect their water bodies and stormwater systems to build resilience against increasing climate threats.
