Though the catchments of the lakes have received more rainfall than last year, the municipal corporation says it’s too early to withdraw the water cuts.
While residential users are facing a 15 per cent water cut, commercial users are facing a 30 per cent cut.
There has been on an average 300 mm of rainfall in all the six lakes that supply water to Mumbai — the highest being in Vihar at 1,019 mm.
In June 2009, the lakes had received an average rainfall of more than 80 mm — maximum being at Vihar at 170 mm.
“There has been 30 to 40 per cent more rainfall than last year,” said Municipal Commissioner Swadheen Kshatriya. “There has been an increase in the water stocks, but it’s too early to roll back the cuts. We will take a stock of the situation in mid-July and then decide.”
The water stock in the six lakes is 1.2 lakh million litres as against 1.3 lakh million litres last year. Civic officials said all catchments collectively need an average 3,000 mm of rainfall. The BMC needs a total stock of 13.5 lakh million litres of water to suffice for the entire year.
There is only 10 per cent of annual useful content in the lakes currently despite heavy rainfall in the catchment area.
“There needs to be at least 7.5 lakh million litres of water in all the lakes collectively, only then the cuts will be withdrawn,” a civic official said.
