Bengaluru faces recurrent flash floods due to erratic rains driven by climate change. Experts suggest applying the “Spong City” Concept by building massive underground tanks in low-lying areas to capture floodwater, a concept successfully implemented in cities like Munich, Beijing, Tokyo, and Pittsburgh.
What is the “Sponge City” concept?
It focuses on retaining and managing water at its source to mitigate flooding and groundwater depletion. It involves strategies like permeable pavements, rooftop gardens, underground tanks and ponds to absorb and store rainwater.
These measures help slow down water flow, naturally filter it, and recharge groundwater. The aim is to make urban areas act like sponges, soaking up rainwater and reducing the risk of floods while replenishing local water resources.
