Mumbai, July 18: The Brihanmumbai Municipal Corporation on Sunday asked citizens to boil water before drinking as heavy rains over the last two days had led to flooding in the water purification complex at Bhandup. The flooding has affected electrical equipment that control the pumping and filtration processes there, one of the major sites of water supply to the country's financial capital, he said.

While the pumping mechanism would be restored in a few hours, much more time will be taken to get the filtration process up and running, the official said, adding that boiling water before drinking was the best precaution at the moment. Mumbai Rains: Heavy Rainfall Wreaks Havoc in the City, Death Toll Rises to 22; IMD Warns of More Heavy Spells Today.
