Mumbai’s Lake Levels Lag: 10% Water Cut Endures Despite Heavy Monsoon Rains – Check Current Water Levels Here

Despite the ongoing heavy rain, Mumbai residents will have to endure the 10 per cent water cut that was implemented earlier this year. Civic officials have reported that while there has been some increase in water levels at Mumbai's supply lakes, it has been slower than anticipated. As of Monday morning, the total water stock across the seven lakes was at 47.29 per cent (6.84 lakh million litres) of their total capacity, showing a modest increase of five per cent over the last 24 hours.

On Sunday, Mumbai witnessed substantial rainfall, with some areas recording triple-digit figures in just a few hours. The India Meteorological Department's Santacruz observatory recorded 176 millimetres of rain from Sunday to Monday morning, while Colaba saw 71 millimetres.

Despite this rainfall, the water levels in the lakes that supply Mumbai remain at a three-year low. Last year, on the same date, the levels were slightly higher at 47.54 per cent. In 2022, they were nearly 88 per cent of total capacity at this time of year, according to an Indian Express report.

Due to the slow rise in water levels, senior officials from the Brihanmumbai Municipal Corporation (BMC) have confirmed that the 10 per cent water cut will remain in place for the foreseeable future. A senior BMC official explained that Mumbai usually experiences its heaviest rainfall in July, which is expected to increase lake levels further this month.

Presently, the available water stock is projected to last until October or November. To ensure sufficient supply until next year, the water cut will continue while the situation is closely monitored. The goal is to reach at least 80 per cent of lake levels by August 15.

Civic officials have noted that each one per cent increase in water stock equates to three days of water usage for Mumbai. The city sources its water from seven lakes: Tulsi, Vihar, Bhatsa, Modak Sagar, Tansa, Upper Vaitarna, and Middle Vaitarna. During the monsoon season, these lakes' catchment areas fill up, and the collected water is then distributed throughout the year via a comprehensive pipeline network.

In the last 24 hours up to 8:30 am, rainfall data showed that Tulsi Lake received the most precipitation at 171 millimetres, followed by Vihar Lake with 133 millimetres. Vaitarna received 88 millimetres, Bhatsa 77 millimetres, Middle Vaitarna 62 millimetres, Upper Vaitarna 52 millimetres, and Tansa 50 millimetres.
