In February 2018, it was widely reported that Cape Town would be the first city in the world to “turn off its taps”. The city was fast approaching what disaster management officials call “day zero”—when the city’s reservoirs would be so far below capacity that people would be forced to go to communal taps to get water. In the end, emergency measures were sufficient to avoid calamity. At the time, in a list of 11 cities around the world most likely to run out of water, Bengaluru was listed in second place, behind Sao Paulo. No other Indian city was on that list, though it was widely acknowledged that many of them were vulnerable to acute water shortages. In the event, it was Chennai that ran out of water first. According to a NITI Aayog report, several other major Indian cities, including the capital, will run out of groundwater next year—although there have been questions on the accuracy and source of that statistic. Prime Minister Narendra Modi has demanded a Swachh Bharat-style mass movement to conserve water. We must hope it’s still possible to pull ourselves back from the brink.
