Flash floods wreak havoc on Bengalureans
Sponge City system to address flash flood havoc
Sponge City system involves retaining water at its source
Bengaluru’s recurrent flash flood challenges could be addressed through the implementation of Sponge City systems and the construction of underground storage tanks.
Year after year, flash floods wreak havoc on Bengalureans, especially those residing in low-lying areas.
Instead of allowing floodwaters to inundate these regions, a viable solution would be the construction of extensive underground tanks.
By harnessing the forces of nature, the pull of gravity, and human innovation, excess water could be efficiently stored, minimizing human suffering. Moreover, this stored water could serve as a valuable resource during dry seasons.
While the upfront investment for such systems is substantial, successful examples can be found worldwide. For instance, in Munich, Germany, 13 underground tanks were constructed to combat recurring floods. These tanks served as reservoirs for floodwaters, which could be pumped out as needed.
Architect Naresh Narasimhan aptly points out that Bengaluru’s issue lies more in storage than in the availability of water.
The concept of a Sponge City system involves retaining water at its source, slowing down its flow, naturally purifying it, and adapting its use at the point where it accumulates.
This model encourages rainwater absorption through various means, such as rooftop gardens, permeable roads, ponds, filtration pools, wetlands, and public spaces designed to facilitate water infiltration. While some smart city roads in Bengaluru have designated areas for water seepage, there is a pressing need to expand and scale up this approach.
Chennai has emerged as a leader among Indian cities in adopting the Sponge City model. Bengaluru should consider following suit, as this system gains traction in cities worldwide.
The Greater Chennai Corporation has embarked on an ambitious plan to transform the entire metropolis into a sponge city, effectively addressing both flood control and groundwater depletion. Bengaluru has compelling reasons to undergo a similar transformation.
