Gurgaon's Flooding Crisis: A City Built Without Topography in Mind

Strategic Insights -

Gurgaon, India's Millennium City, is notorious for its extreme flooding during monsoons, with hours-long traffic jams, floating cars, and electrocutions being common occurrences. Despite receiving only an average of 600 mm of rain annually, Gurgaon's flooding problem persists, leaving nearly 2 million residents vulnerable. The city's unique topography, with the Aravalli ridge and its natural drainage channels, has been ignored in urban planning, making it prone to surface runoff and flooding.

Key Takeaways:

  • Gurgaon's topography, with the Aravalli ridge and natural drainage channels, has been ignored in urban planning, leading to flooding.
  • The city's unique land acquisition model, which enabled private firms to acquire land on a large scale, has led to piecemeal planning and irregular plots.
  • Gurgaon's drainage system, consisting of concrete drains, is inadequate and adds to the flooding problem.
  • Three common sense solutions proposed by architect-urban designer Suptendu Biswas include identifying local green areas for water harvesting, creating soft drains beneath pavements, and sloping roads to allow water to drain off.
  • The city's homes, factories, and commercial buildings have largely replaced mustard fields and natural canals, which were once essential for absorbing excess rainwater.
  • Gurgaon's engineers and planners have overlooked the importance of earth in their design, opting for steel and concrete instead.

Statistics:

  • Gurgaon receives an average of 600 mm of rain annually (The Indian Express).
  • Kochi receives over 3,000 mm of rain annually without experiencing flooding (The Indian Express).
  • Gurgaon has barely four natural canals remaining, down from 60 in the past (The Indian Express).
  • The city's topographic relief, with the Aravalli ridge, slopes down towards the north, making rainwater flow towards Najafgarh Jheel in West Delhi (The Indian Express).
  • Urban expansion in Gurgaon has not kept up with topographic realities, with roads built without proper gradients and big picture thinking (Suptendu Biswas, Gurgaon to Gurugram: A short biography, 2021).
