Mumbai Water Stock Rises To 62% After Tansa Lake Overflows

Mumbai's water stock has risen to 62% of its combined storage capacity after Tansa Lake, one of the seven lakes supplying drinking water to the city, began overflowing on Wednesday. The lake, located in Thane district, started overflowing at 8.51 am, pushing the city's total water stock to 8.95 lakh million litres (ML).

The recent spell of heavy rainfall has significantly improved lake levels, with Tansa becoming the third lake to overflow this monsoon after Tulsi and Vihar on July 7. Tansa supplies 455 ML per day of water to Mumbai, and its overflow has boosted the city's water stock.

The monsoon reached Mumbai nearly two weeks late on June 23, and an extended dry spell had triggered concerns over dwindling lake levels, prompting the BMC to impose a 10% water cut from May 15. However, heavy rainfall across Mumbai and the lake catchment areas in early July has brought much-needed relief.

The current water stock is now sufficient to meet Mumbai's needs for 219 days. The water levels in the other lakes are also improving, with Modak Sagar at 90% capacity, Bhatsa at 57%, Middle Vaitarna at 53%, and Upper Vaitarna at 39%.

Despite the improving water levels, the BMC is not considering withdrawing the 10% water cut. A senior civic official said the civic body will wait until all seven lakes are adequately filled, particularly as forecasts indicate below-normal rainfall this monsoon.

Mumbai requires 14.47 lakh ML of water to meet its annual demand. The BMC will continue to monitor the water levels and adjust the water cut accordingly.

The overflow of Tansa Lake is a significant development, and it will help to alleviate the water shortage in Mumbai. The city's water supply is secured for 219 days, and the BMC will work to ensure that the water levels remain stable.

The improvement in water levels is a result of the heavy rainfall in the lake catchment areas. The BMC has been working to improve the water supply infrastructure, and the recent rainfall has helped to boost the water stock.

In conclusion, the overflow of Tansa Lake is a positive development for Mumbai, and it will help to ensure that the city's water supply remains stable. The BMC will continue to monitor the water levels and work to improve the water supply infrastructure.

The water stock in Mumbai as on July 22 is as follows: Upper Vaitarna - 88631 ML, Modak Sagar - 116181 ML, Tansa - 142122 ML, Middle Vaitarna - 102585 ML, Bhatsa - 410644 ML, Vehar - 27698 ML, and Tulsi - 8046 ML.

The BMC has advised citizens to use water judiciously and to report any water-related issues to the civic body. The city's water supply is a critical issue, and the BMC is working to ensure that it remains stable.

The recent rainfall has brought relief to the city, and the BMC is working to ensure that the water levels remain stable. The overflow of Tansa Lake is a significant development, and it will help to alleviate the water shortage in Mumbai.
