Mumbai Water Levels Climb Above 8% After Heavy Monsoon Rains as Reservoir Storage Sees Strong Daily Increase

Heavy Rainfall Boosts Mumbai's Water Supply While IMD Forecasts More Intense Showers Across the City

Mumbai's water reserves continued to improve on July 2 as persistent monsoon rainfall across the city and surrounding catchment areas significantly increased water storage in the seven lakes that supply drinking water. According to the latest data released by Mumbai's Hydraulic Engineer's Department, the city's reservoirs now hold 1,17,532 million litres of water, representing 8.12% of the total useful storage capacity.

Mumbai Water Storage Records Strong 24-Hour Increase

The latest figures show a healthy rise in water reserves compared to the previous day. On July 1, Mumbai's reservoirs contained 1,03,871 million litres, or 7.18% of useful storage. Within just 24 hours, continuous rainfall added 13,661 million litres of water to the city's reservoirs, reflecting the positive impact of active monsoon conditions across the lake catchment areas.

The steady increase comes as rainfall continues across the region, providing an encouraging boost to Mumbai's drinking water supply early in the monsoon season.

Modak Sagar, Vihar and Tulsi Register Significant Storage Levels

Among Mumbai's seven reservoirs, Modak Sagar reported one of the strongest storage levels at 22.35% of useful capacity. Vihar Lake reached 57.18%, while Tulsi Lake climbed to 33.96%.

Other reservoirs also showed gradual improvement. Middle Vaitarna stood at 12.38%, Bhatsa reached 5.72%, and Tansa recorded 3.60% useful storage. Upper Vaitarna remained below its live storage level and has yet to begin contributing to usable water reserves.

Heavy Rainfall Across Catchment Areas Improves Reservoir Inflows

Continuous rainfall across Mumbai and the surrounding lake regions played a key role in increasing water storage. The Bhandup Complex recorded 219 mm of rainfall during the last 24 hours, taking its cumulative seasonal rainfall to 763 mm.

Strong rainfall was also reported across important catchment areas, including Tulsi, Vihar, and Modak Sagar, resulting in higher inflows into the reservoirs and supporting the steady rise in overall water stock.

Heavy Monsoon Continues Across Mumbai

Mumbai continued to receive heavy to very heavy rainfall after overnight showers affected several parts of the city. Waterlogging was reported in multiple low-lying areas, while road traffic slowed considerably and suburban railway services experienced delays in some sections during the morning rush.

The ongoing rainfall has created challenging travel conditions, although it has also contributed to improving the city's drinking water reserves.

IMD Forecasts More Heavy Rain and Gusty Winds

Weather authorities have forecast that heavy to very heavy rainfall will continue across Mumbai and its suburbs over the coming hours. Isolated areas could receive extremely heavy rainfall, particularly during late night and early morning periods.

The forecast also warns of gusty winds reaching 50 to 60 km/h, with residents advised to remain alert as the active monsoon system continues to influence weather conditions across the Mumbai Metropolitan Region.

As the monsoon progresses, consistent rainfall across the catchment areas is expected to further improve reservoir storage and strengthen Mumbai's water supply in the weeks ahead.
