Lakes overflow, water cut stays

Four of the six lakes supplying water to Mumbai are overflowing but the Brihanmumbai Municipal Corporation is not ready to withdraw the 7 to 10 per cent water cut.

The civic body is waiting for one of the two state-owned dams, Bhatsa or Upper Vaitarna, to start overflowing. These two dams together supply 80 per cent of the water required in Mumbai.

Bhatsa is six metres away from the overflow mark while Upper Vaitarna is less than four metres away from overflowing.

The BMC had imposed a 15 per cent cut in water supply before the monsoon. This was reduced to 10 per cent last month.

On August 14, the civic body increased water supply by 100 million litres daily (MLD) following good rainfall.

Since this additional supply is subject to lakes receiving more water, the water cut in Mumbai is in the range of 7 to 10 per cent.

Over the past two days, the city has received heavy rainfall causing Vihar Lake in Powai to overflow early on Thursday morning.

Four of the six lakes that supply water to Mumbai are now overflowing.

The total water stock in all the six lakes is 10.77 lakh million litres as against 7.30 lakh million litres last year, this time.

"The water stock in all the six lakes is improving gradually every day. The civic body is supplying 3,230 million litres of water daily (MLD) as against 2,900 MLD being supplied earlier," said an officer from the BMC requesting anonymity.

Mumbai's daily demand for water is 4,200 MLD.

"Instead of letting the overflowing water go to waste, we have been supplying it to users. That's how water cuts have reduced by 7 per cent," the officer said.

Vihar lake, the oldest in the city, supplies at least 110 million litres of water to Kurla, Kalina and Powai and for industrial use.

Last year, it had reached its lowest drawable limit and water from other reservoirs was being transferred to it to prevent it from drying.

The catchments continue to record good rainfall with the maximum recorded over Tulsi 127 mm in the last 24 hours.

The municipal corporation takes stock of the water levels on October 1 and then budgets the supply distribution for the city for the year.
