To ensure the city does not have to suffer further water cuts, the Brihanmumbai Municipal Corporation has dipped into its reserve stock in May, a month earlier than usual. Stock from the Upper Vaitarna reservoir is being utilised since last week to keep up BMC's daily water supply levels for the city at 3,550 million litres. The civic body had planned to use water from Upper Vaitarna and Bhatsa to avoid any situation of panic in case of a delayed monsoon.

The useful live content of Upper Vaitarna has fallen to zero. BMC had written to the state government to allow the use of the Upper Vaitarna and Bhatsa's reserve stock and received the nod for it earlier this month. Immediately after the permissions came in, BMC made plans to use the stock to avoid any panic situation that could grip the city in case of a delayed monsoon.
