Heavy rainfall since July 1 in the catchment areas has substantially increased the amount of water in the seven lakes that supply Mumbai. The total quantity of water in the seven lakes supplying water to the city was 2.9 lakh million litres till Saturday, inching closer to the amount recorded the same time last year — 3 lakh million litres.
Rain has added 1.8 lakh million litres to the seven lakes since July 1. This is enough to tide over the city’s requirement for 50 days.
Starting October 1, the city requires 14.36 lakh million litres to go without water cuts till July 2017. Owing to poor rainfall in 2015, Mumbai has been facing a 20% water cut since August 2015. The city’s requirement is estimated at 3,750 million litres per day. Mumbaikars have been receiving 3,200 million litres instead.
Ashok Tawadia, chief hydraulic engineer, BMC, said, “Rainfall in the catchment areas in the last one week has been good. We have met more than 20% of the city’s requirement for the next year.”
On Saturday, Bhatsa, which caters to more than 50% of Mumbai’s water needs, had 1.6 lakh million litres. This is 71 thousand million litres more than what was recorded the same time last year. Vehar has 5 thousand million litres in addition to what was recorded on the same day last year. The lake has also received 1,663mm rainfall since June 1, the highest of the rainfall recorded in all the seven lakes.
Tansa, which caters to 10% of the water requirement needs of the city, has 47 thousand million litres, which is 20 thousand million litres more than what was recorded the same time last year. In 2015, Tansa had 26 thousand million litres of water for the same period. Tulsi, which suffices 1% of Mumbai’s water needs, has also recorded 3 thousand million litres of water. The lake has received 1,566mm rainfall till July 9, the second highest after Vehar.
