Tansa lake overflows: 4 out of 7 lakes supplying water to Mumbai now full
Amid the healthy spell of rainfall, Tansa lake on Tuesday became the fourth lake, out of the seven that supply water to Mumbai, to start overflowing.
According to civic officials, the lake started overflowing around 6 am today morning. Incidentally, the lake had started overflowing on the same day last year. Tansa supplies around 400 million litres of water to the city every day.
Earlier on Wednesday, Vihar lake had started overflowing. Prior to that, Tulsi and Modak Sagar lakes got filled to the brim on July 9 and 15 respectively.
Mumbai’s water supply comes from seven lakes – Modak Sagar, Tansa, Vihar, Tulsi, Upper Vaitarna, Bhatsa and Middle Vaitarna. While five of them are maintained by the BMC, two (Bhatsa & Upper Vaitarna) come under the state government’s control.
Since the city received more rainfall than catchment areas, Tulsi and Vihar lakes – which are situated within city limits at Sanjay Gandhi National Park – were among the first ones to get filled.
The seven lakes supply approximately 3,750 million litres of water to the city every day. They need to have 14.47 lakh million litres of water stock by end of monsoon to avoid water cuts.
Before 2016, the civic body was forced to impose water cuts throughout the city due to insufficient rainfall. The situation, however, improved in the last two years, as a result of which the BMC lifted the cuts.
