Vihar Lake, one of the city-based reservoirs which supplies potable water to the mega-polis, started overflowing from the wee hours on Monday, civic officials said.
The lake started overflowing since 4:20 AM, officials of the Municipal Corporation of Greater Mumbai (MGCM) said.
Mumbai has already received 75 per cent of its average rainfall in the first two months of the rainy season, they said.
The full supply of Vihar Lake is 80.12 meters and it reached upto 80.23 meters at 6 AM, a MCGM statement said.
On July 19, the Tulsi Lake, which also supplies potable water to the city, had started overflowing.
“Significant rain is taking place in the catchment areas (of the reservoirs which supply water to Mumbai) and we hope to get all the reservoirs filled in this year’s Monsoon,” he added.
The total amount of water stock in the seven reservoirs, which supply water to Mumbai, as of today was 10.31 lakh million litres which was 8.34 lakh million litres on the same day last year, it said.
Mumbai’s water supply comes from seven reservoirs which store rainwater collected during the rains.
These are Modak Sagar (built in 1957), Tansa Lake (built in 1925), Vihar Lake (built in 1860), Tulsi Lake (built in 1879), Upper Vaitarna (built in 1973), Bhatsa (built in 1983) and Middle Vaitarna (built in 2012).
Bhatsa and Upper Vaitarna come under Maharashtra governments control while the rest are managed and maintained by the MCGM.
The civic body supplies 3,750 million litres of water everyday to the island city and suburbs, which falls short of the actual demand for 4,200 million litres.
In recent past, insufficient rainfall had forcing MCGM to cut short the water supply at times.
Recently, the civic body had revoked 20 per cent cut in the water supply to the mega-polis, which was imposed in August last year.
