Mumbai: Mumbai’s water stock has witnessed a significant decline as the city continues to experience above-normal temperatures for nearly three weeks. According to reports citing data from the Brihanmumbai Municipal Corporation (BMC), the water level in the city’s seven lakes stood at 45.08 per cent as of March 9, marking a six-percentage-point drop in the last 15 days. On February 24, the water stock was at 51 per cent.

Decision Regarding Water Cuts This Week

Civic officials have indicated that a decision regarding water cuts will be taken this week, reported the Indian Express. Meanwhile, the India Meteorological Department (IMD) has issued a heatwave warning for Mumbai from March 9 to 11. This comes after the city experienced a heatwave between February 25 and 26.

Officials have attributed the rapid decline in water reserves to the ongoing extreme temperatures. If the current trend continues, water levels may dip faster than anticipated. Although an immediate water cut is unlikely, officials have warned that restrictions may be imposed in the coming months, especially with the monsoon still three months away.

Water Stock In Excess This Year, Compared To 2024

BMC officials noted that each percentage point of water stock roughly accounts for two to three days of consumption. The current stock is sufficient to sustain the city for approximately four months. Last year, during a similar period, Mumbai’s water stock was at 39.73 per cent, while in 2023, it stood at 45.23 per cent.

Officials recalled that in 2023, extreme daytime temperatures led to water cuts around May. Although the monsoon typically arrives between June 10 and 15, majorly rainfall in the lakes' catchment areas often occurs later. This delay can put additional pressure on water reserves.

Reserve Water Stock Used Last Year By BMC

Last year, following a delayed monsoon, the BMC had to rely on reserve water after obtaining approval from the state’s irrigation department. However, the reserves were replenished once rainfall picked up in July.

Mumbai relies on seven lakes for its water supply: Tansa, Bhatsa, Tulsi, Vihar, Upper Vaitarna, Middle Vaitarna and Modak Sagar. Of these, Tulsi and Vihar are located within the city limits, while the remaining lakes are spread across the satellite districts of Palghar, Thane, and Nashik. The total storage capacity of these lakes is 14.47 lakh million litres.

With summer intensifying and water levels continuing to fall, authorities are closely monitoring the situation. While immediate action may not be required, officials remain cautious and are preparing for any necessary interventions should the high temperatures persist.
