A report by BBC based UN-endorsed projections listed 11 countries across the globe likely to run out of drinking water. Karnataka capital, Bengaluru is the only Indian city listed in the report.
The reported cited the growth of real estate developments following the rise of the city as a technological hub. And the local officials are struggling to manage the city's water and sewage systems. Also, loss of over half of its drinking water due to antiquated plumbing is one of the reasons for the crisis.
