The water levels in lakes supplying drinking water to Mumbai have risen following heavy rainfall in their catchment areas. According to the Brihanmumbai Municipal Corporation`s (BMC) Mumbai rains data, the combined stock in the seven reservoirs that provide water to the city now stands at 99.46 per cent.
As per the BMC`s Mumbai rains data on Sunday (September 28), the collective water stock in these reservoirs is 1,439,588 million litres, which amounts to 99.46 per cent of their total capacity.
The BMC supplies drinking water daily from Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vehar, and Tulsi lakes.
Among the major reservoirs, Upper Vaitarna is holding 226,083 million litres, at 99.58 per cent of its capacity. Modak Sagar and Tulsi have both reached 100 per cent capacity, storing 128,925 ML and 8,046 ML, respectively. Tansa, another key contributor, is also nearly full at 144,946 ML, standing at 99.58 per cent.
Middle Vaitarna currently holds 190,157 million litres, which is 98.56 per cent of its live storage. Bhatsa, one of the largest lakes serving the city, has reached 99.35 per cent, storing 712,373 ML. Vihar Lake has also filled completely, with a storage of 27,698 ML.
Over the past 24 hours, the lake levels have seen minor increases, ranging from 0.09 to 0.17 meters, reflecting the continued rainfall activity in the catchment areas.
Steady rainfall continues to feed the lake systems. The Bhandup Complex, which oversees lake levels, recorded 107.00 mm of rainfall in the last 24 hours. The total seasonal rainfall over the lake catchments has now reached 2,895.00 mm.
Among the individual lakes, Tulsi received the highest rainfall at 106 mm, followed by Bhatsa (58 mm) and Vihar (53 mm). Upper Vaitarna and Modak Sagar received 72 mm and 96 mm, respectively, further supporting their near-full storage levels.
Due to the abundant rainfall, several lakes have already started releasing water. Upper Vaitarna began discharging on 21 August, while Middle Vaitarna’s gates were opened on 18 August.
Modak Sagar started overflowing as early as 9 July, followed by Tansa on 23 July. Bhatsa and Tulsi also overflowed by mid-August, while Vihar Lake reached capacity and started overflowing on 13 August.
