Mumbai Rains: Lakes Supplying Water To City Nearly 97% Full


According to a latest report received by the Brihanmumbai Municipal Corporation (BMC), the seven lakes that supply drinking water to the city are 96.91 per cent full as on August 22.

This development came after the catchment areas of the seven lakes collectively received 59 mm of rain in the past 24 hours.

These lakes have 1,402,616 million liters (ML) of water stock against a total capacity of 14,47,363 ML. It is the highest on this day in the past two years.

On August 22 in 2021, the seven lakes had 86.86 per cent water stock or 1,257,251 ML while on August 22 in 2020, they had 92.38 per cent water stock or 1,337,089 ML.

Of these seven lakes, Modak Sagar, Vihar and Tulsi are 100 per cent full. Modak Sagar lake started overflowing on July 13, Tulsi on July 1 and Vihar on August 11. Tansa has 143,534 ML useful water content and is 98.93 per cent full. It had started overflowing on July 14.

Bhatsa lake is 96.14 filled to capacity and has 689,327 ML of useful water content. It supplies 5,75,700 ML of its total available water stock to Mumbai while the rest is used by the state irrigation department.

The civic body supplies 3,850 million liters of water daily against the city’s demand for almost 4,400 million litres.

Accordingly, taking into account evaporation from the surface of the lakes and loss of water during transport and distribution, Mumbai’s lakes have water stock to last for 330 days.

These lakes are Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar and Tulsi, located either in Mumbai at Sanjay Gandhi National Park or neighboring districts of Thane and Palghar.
