Heavy rain in cachment areas is filling lakes supplying water to the city. The lakes have received record rainfall this year — up to over four times the previous three years.

Though water level in Bhatsa lake,which meets 59 per cent of the city’s water need — has not seen a marked increase,it received the most rain in the last four years Friday.

Upper Vaitarna and Modak Sagar,which provide for more than 29 per cent of the city’s water need,have risen by 0.14 metres. The lakes have so far received 94.8 mm and 72.6 mm of rainfall – over seven times what it received last year.

The smaller lakes of Tulsi and Vihar,which account for less than 10 per cent of the city’s water supply,received the highest amount of rain at 528 mm and 298 mm and rose by 0.34 metres and 0.44 metres.

Tansa lake rose 0.02 metres after receiving 133.2 mm of rain.

“If the city continues to receive such rain,the lakes will fill well in time to meet citizens’ needs for the rest of the year,” said a senior official in the BMC water supply department.

BMC is supplying 3,228 million litres per day,well short of the 4,200 mld the city requires.

In 2011,owing to poor rainfall and deficient water harvesting,the city had faced a 10 per cent water cut from June to September.
