Mumbai Water Stock Reaches 89.08%
Mumbai's water stock nears 90%, reservoir levels rise due to monsoon

Mumbai's seven lakes, which supply drinking water to the city, have reached 89.08% of the required capacity, according to the Hydraulic Engineer's Department. The city's water stock registered a 0.67 percentage-point increase in a day, climbing from 88.41% to 89.08%.
The current water stock is 12,89,289 million litres (ML) of usable water against the full storage capacity of 14,47,363 ML. This reflects a steady increase due to sustained monsoon rainfall.
Mumbai Mayor Ritu Tawde shared the latest status of the city's seven major reservoirs, stating that the water stock was steadily increasing due to the ongoing monsoon. Among the seven lakes, Modak Sagar and Vihar Lake have reached 100% capacity, while Tansa stands at 99.58% and Tulsi at 99.46%.
Middle Vaitarna has filled up to 91.65%, Bhatsa, Mumbai's largest drinking water source, is at 87.14%, and Upper Vaitarna is at 78.39% of its live storage capacity. The current stock is also slightly higher than the 88.94% recorded on the corresponding day last year.
Over the last 24 hours, Upper Vaitarna received the highest rainfall at 112 mm, followed by Middle Vaitarna (66 mm), Modak Sagar (58 mm), Bhatsa (30 mm), Tansa (25 mm) and Tulsi (9 mm), while Vihar recorded no rainfall.
Four reservoirs, including Vihar Lake, Tulsi, Tansa Dam, and Modak Sagar Dam, have started overflowing due to strong monsoon inflows. With water reserves now nearing 90% of total live storage capacity, Mumbai remains in a comfortable position in terms of drinking water availability.
The continued monsoon rainfall is expected to further replenish the reservoirs in the coming days. The city's water stock is likely to reach 90% capacity soon, ensuring a steady supply of drinking water to the city's residents.
The monsoon season has brought relief to the city, with the water stock increasing steadily over the past few weeks. The BMC has been monitoring the water levels closely, and the latest update suggests that the city's water supply is secure for the time being.
In terms of significance, the increasing water stock is a positive development for Mumbai, as it ensures that the city's residents have access to a steady supply of drinking water. The monsoon season is crucial for replenishing the city's water reservoirs, and the current trend suggests that the city is on track to meet its water needs for the year.
