The latest figures from the Brihanmumbai Municipal Corporation’s (BMC) water supply department show that the seven lakes supplying water to Mumbai have barely enough to last for the next 60 days.
The total useful water content in all seven lakes stands at 2.26 lakh million litres. The BMC supplies 3,750 million litres of water every day to the island city and suburbs, which still falls short of the demand for 4,200 million litres every day.
The level of Bhatsa lake, which accounts for 59 per cent of the total water supply for Mumbai, stand at 108.7 metres and is reaching its lower limit of 104.9 metres. During the monsoons, it should reach its maximum level of 142 metres to ensure sufficient water for the city till the next monsoon. The total usable content in the lake is 1.05 lakh million litres, 56,912 litres less than the level recorded at the same time last year.
Vehar lake is also reaching its lower limit of 73 metres. It currently stands at 74 metres, of which 934 million litres is useful content.
The Upper Vaitarna has already gone below its lower limit of 595 metres. The current level is 593 metres, with no useful content.
Upper Vaitarna and Modak Sagar together account for 29 per cent of the city’s water supply. The total usable content in Modak Sagar is 18,089 million litres less that what was recorded at the same time in 2014.
The situation is worrying, especially with fears of a deficient monsoon. A senior civic official from the water department said, “The water is sufficient till July 31. We are not considering any water cuts for now. We will take a call later depending on the situation.”
