Mumbai’s water supply outlook has significantly improved as the combined water level in the city’s seven lakes rose to 35%, a dramatic increase from just 5.31% during the same period last year. The surge follows consistent rainfall across catchment areas, offering much-needed relief to residents and civic authorities.
Monsoon Showers Replenish Reservoirs
According to the Brihanmumbai Municipal Corporation (BMC), the seven reservoirs—Bhatsa, Upper Vaitarna, Middle Vaitarna, Modak Sagar, Tansa, Tulsi, and Vihar—now hold over 506,000 million litres of water. This is a substantial improvement from the 74,000 million litres recorded in June 2024.
- Upper Vaitarna: 29.14% full
- Middle Vaitarna: 23.51%
- Modak Sagar: 44.38%
- Tansa: 28.62%
- Tulsi: 37.67%
- Vihar: 39.61%
- Bhatsa: 20.92%
97 Days of Water Supply Secured
With Mumbai’s daily water requirement at approximately 3,850 million litres, the current stock is estimated to last 97 days without additional rainfall. The city’s annual water demand stands at 1,447,363 million litres, and the current storage marks a promising start to the monsoon season.
Water Cuts to Continue—For Now
Despite the improved levels, the BMC has decided to maintain the existing 10% water cut, citing the need for sustained rainfall to ensure long-term stability. Officials remain cautiously optimistic, with the India Meteorological Department (IMD) forecasting more showers in the coming days.
A Welcome Turnaround
The sharp rise in lake levels comes after a worrying dry spell earlier this month, when storage had dipped below 12%. The turnaround is attributed to targeted rainfall in catchment zones and improved water retention strategies.
