Steady rainfall since few days has resulted in Tulsi Lake — situated in the Sanjay Gandhi National Park in Borivli — to overflow on Monday evening.
While Tansa Lake and Modak Sagar are also on verge of overflowing, said civic official.
Tulsi Lake supplies 18 million litres of water every day to the city, which is a very small as compared to 3,400 million litres required by the city. But its overflowing has bought hope to the water starved city.
In the last 24 hours there has been an increase of over 42,000 million litres of water in the lakes.
On Sunday there was 8.6 lakh million litres of water in all the six lakes. By Monday it increased to 90 lakh million litres. If rains continue, the water cuts in the city may not happen, the civic officials said.
But according to the civic body, it's too early to begin the celebrations. The city has nine lakh million litres in its lakes, while it had 12 lakh million litres at the same time last year.
“Tulsi and Tansa are small lakes so their overflow will not help us in a big way,” said Additional Municipal Commissioner Anil Diggikar.
Tansa has reached 99 percent of its capacity. Modak Sagar has touched 162.09 m, short of its 163.15 m full capacity.
“Unless other lakes get full, we can continue to call it a water crisis. But if it does not continue to rain, the overflow will stop and the level will reduce,” said Pramod Guhe, deputy hydraulic engineer.
As of 3 pm on Sunday, Modak Sagar and Upper Vaitarna recorded no rainfall, Tansa got 5mm, Vihar got 81mm, Tulsi received 36mm and Bhatsa received 16mm rainfall.
The agenda of cleaning and constructing bore wells in the city will be tabled before the standing committee on Wednesday. The cost of the proposal is Rs 1.25 crore.
