In heavy rain, Mumbai’s new drainage system failed
Several areas in Central Mumbai and suburban Khar and Bandra were flooded even before the hourly intensity of rain increased to 50 mm, which is also the maximum capacity of the city’s upgraded stormwater drainage system.
Shockingly, Mumbai’s storm water drainage system was built during the British rule. Since then, no government has tried to build an advanced drainage system. At present, the city’s drainage system is capable of handling 25 mm rain. Roads get flooded if it rains more than this.
Is there any solution to Mumbai’s water woes?
