Mumbai’s water reserves received a significant boost on Tuesday as persistent monsoon showers across the catchment areas pushed the city’s reservoir storage to 61.90% of its total live capacity, easing concerns over water availability in the coming months.
According to the latest data released by the Hydraulic Engineer’s Department, the seven lakes supplying drinking water to Mumbai now hold 8,95,907 million litres of water. Reservoir levels witnessed a sharp increase of 4.15 percentage points in just 24 hours, reflecting the impact of widespread rainfall across the region.
Two Lakes Reach Full Capacity
Among Mumbai’s key water sources, Vihar Lake and Tulsi Lake have reached 100% capacity, while Tansa Lake is close behind with 97.96% storage. Modak Sagar has risen to 90.12%, strengthening the city’s overall water reserves.
Other reservoirs also recorded healthy storage levels. Bhatsa, one of Mumbai’s largest water suppliers, stands at 57.27%, Middle Vaitarna has reached 53.01%, and Upper Vaitarna currently holds 39.04% of its live storage capacity.
Heavy Rainfall Across Catchment Areas
Continuous rainfall across the reservoir catchment zones has been the primary reason for the rapid increase in storage.
Over the past 24 hours:
- Upper Vaitarna recorded 224 mm rainfall.
- Bhatsa received 96 mm.
- Middle Vaitarna registered 71 mm.
- Tulsi received 71 mm.
- Tansa logged 70 mm.
- Modak Sagar recorded 67 mm.
- Vihar received 65 mm.
Meanwhile, the Bhandup Complex recorded 52 mm rainfall, taking its cumulative seasonal rainfall to 2,006 mm.
Monsoon Continues to Improve Water Situation
The steady rise in reservoir levels comes amid an active monsoon spell across Mumbai and neighbouring districts. The improved storage position has considerably strengthened the city’s drinking water reserves, reducing immediate concerns over supply during the remainder of the season.
At the same time, the India Meteorological Department (IMD) has issued an Orange Alert for Mumbai, warning of heavy to very heavy rainfall, thunderstorms and gusty winds. Civic authorities continue to monitor weather conditions, while residents have been advised to remain cautious in low-lying and flood-prone areas.
