The monsoon this year has given Mumbaiites enough reasons to cheer. Thanks to adequate rainfall over the past few months, five out of six lakes, which supply water to the city, are overflowing, said the civic body.
As the lakes have started overflowing, it is safe to declare that there is enough water to last for the dry, non-monsoon months during the rest of the year. The lakes need to have a collective water stock of 13 lakh million litres to last throughout the year. The civic hydraulic department reviewed the water stock in six lakes on September 28 and said the water stock in all six reservoirs will last for the next 11 months.
Ramesh Bambale, civic hydraulic engineer, said, “Though the drinking water requirement of the city is much more than the current supply, we can continue existing supply, 3,350 million litres per day till next year. There is no need to impose any water cuts.”
In order to ensure that no water cuts are imposed throughout the year, the city requires a total of 12.5 to 13 lakh million litres in all its six lakes — Tulsi, Modak Sagar, Tansa, Vihar, Upper Vaitarna and Bhatsa. Of the six lakes, five have over flown while Upper Vaitarna is a few inches below the overflow level.
According to civic officials, the total stock in the lakes stands at 12.32 lakh million litres. The situation is almost same as last year, when the water stock stood at 12.34 lakh million litres, just 2,000 million litres more than this year.
The civic body supplies 3,350-million litres water per day against requirement of 4,200 million litres.
The civic officials, however, are hoping that water supply will increase by 455 million litres in 2012, after commission of the Middle Vaitarna Dam. “Additional 455 million litres of water will be distributed on population basis,” said Rajiv Jalota, additional municipal commissioner.
