If rains continue to play truant, the municipal corporation may have to increase the water cut from the current 15 per cent.
Since the last 10 days, the catchment areas of the six lakes at supply water to the city have received very little rainfall, resulting in the lake levels dipping.
Modak Sagar, the only lake that overflowed 10 days ago, has dipped by 1 metre.
On Monday, the level of Modak Sagar was recorded at 162.83 m, while it was 163.15 m on August 1.
Civic officials said the current water stock would last for just 160 days, when the minimum should be for 240 days for the city to get uninterrupted supply till next monsoon arrives.
“We will review the rainfall situation over the week and will also consult the Meteorology department about the amount of rainfall expected through the week,” said a senior civic official, requesting anonymity for lack of authorization to speak to the media.
The corporation will review the supply scenario this week and then decide how much water cut will be imposed.
“The water cut will continue till the lakes are at least 80 per cent full. Modak Sagar was 100 per cent filled, but now its level too has dropped,” said Municipal Commissioner Jairaj Phatak.
The situation has also prompted the municipal corporation to hasten the cloud seeding plans.
The Meteorological department on Monday predicted a few spells of rains or thundershowers in the next 24 to 48 hours.
