Mumbai’s Water Supply Remains Strong as Reservoirs Near Full Capacity
Mumbai’s water supply continues to remain robust, with the seven lakes that provide drinking water to the city reporting healthy levels as of 6:00 AM on Tuesday, September 23, 2025. According to the Brihanmumbai Municipal Corporation (BMC), the collective water stock is near full capacity, ensuring an adequate supply for the city in the coming months.
Reservoir Levels Overview
– **Upper Vaitarna Reservoir** stood at 603.81 meters with a live storage of 226,083 million liters, which is 99.51% of its total capacity. Despite scarce rainfall recorded today, it remains the city’s most reliable water source.
– **Modak Sagar**, another key supplier, reported water levels at 603.45 meters with 128,925 million liters in storage and no fresh rainfall.
– **Tansa Lake** is holding 145,080 million liters at 128.38 meters and saw no rainfall in the last 24 hours.
– **Middle Vaitarna** recorded a marginal 0.11 mm of rain, with water levels reaching 284.67 meters and storage at 192,564 million liters.
– **Bhatsa Lake**, the city’s largest reservoir, measured 141.65 meters with 705,514 million liters in stock, although it also recorded no rainfall today.
– **Vehar Lake**, smaller but vital, is full at 27,698 million liters with levels standing at 80.26 meters.
– **Tulsi Lake** held 8,046 million liters at 139.24 meters and reported no rainfall.
Monsoon Impact and Water Management
Officials noted that several dams had begun overflowing between July and August, a sign of healthy monsoon rains. The Upper Vaitarna had released excess water on August 21, helping to regulate reservoir levels safely during the peak monsoon period.
The Bhandup Complex, central to water treatment and distribution across Mumbai, recorded a cumulative rainfall of 2,770 mm this season. Today’s rainfall in the area was measured at 42 mm, contributing positively to overall storage stability.
Historical Comparison of Reservoir Levels
Looking back over the past five years, 2025 stands out as one of the healthiest seasons for reservoir storage:
– 2025: 99.02% capacity
– 2024 (late August): 94.87%
– 2023: 83.01%
– 2022: 96.91%
– 2021: 86.86%
– 2020: 92.38%
The last time Mumbai’s seven major lakes supplying drinking water reached near 99% full capacity was around October 1, 2024, recording 99.37%.
Outlook and Conservation Appeal
With lake levels nearly full, Mumbai is well-positioned to face the post-monsoon and upcoming summer months without the threat of immediate water cuts. However, civic authorities continue to urge citizens to use water judiciously, emphasizing the importance of conservation even during times of abundance.
