Mumbai is staring at a severe water crisis as the combined live storage in its seven supply reservoirs has dropped to less than 7 per cent, significantly lower than last year, due to delayed monsoon and insufficient rainfall so far this year. In the corresponding period last year, the water stock in these seven dams was 39.5 per cent. As per the data from the Brihanmumbai Municipal Corporation's Hydraulic Engineer's Department, the seven reservoirs together held 1,00,279 million litres of water, or 6.93 per cent of their total live storage capacity, at 6 am (on Monday), compared with 5,71,670 million litres (39.5 per cent) on the corresponding day last year.
