Water Supply Update:

As of August 5, 2024, water storage in the lakes and dams supplying Mumbai has improved significantly compared to early July, when levels were less than half of those in the previous two years. The recent rains have substantially increased water levels, and current storage is now higher than in the past two years. Presently, 90% of the water capacity has been reached in these reservoirs. For comparison, on this date, the water levels are at 80% of last year’s and 89.78% of the 2022 levels.

On Sunday, several key reservoirs, including Tulsi, Tansa, Vihar, Modak Sagar Lake, and Madhya Vaitrana Dam, began overflowing. The Bhatsa Dam, which provides over 60% of Mumbai's water, has reached 88.87% of its capacity. Due to the overflow from these five lakes and dams, the total water storage has risen to 13,02,619 million liters as of August 5, 2024. This is 90% of the required 14,47,363 million liters needed to meet Mumbai's annual water demand.

Currently, Mumbai is awaiting the filling of the Upper Vaitarna and Bhatsa Dams, which hold 75.76% and 88.37% of their capacities, respectively. It is crucial that these reservoirs reach full capacity by October 1, 2024, to ensure a sufficient water supply for the coming year. The actual water storage levels and future supply will depend on whether the lakes overflow by the end of September and the continuing impact of rainfall.
