Mumbai Water Stock Reaches 90.06%

Mumbai's water reserves have continued to improve due to steady monsoon rainfall across the catchment areas. As of Monday, August 3, the combined stock in the seven lakes supplying drinking water to the city has crossed the 90 per cent mark.

The total useful water stock now stands at 13,03,500 million litres, which is 90.06 per cent of the total live storage capacity of 14,47,363 million litres. This is a rise of 0.98 percentage points in the city's water reserves over the past 24 hours.

On Sunday, August 2, the combined water stock in the seven reservoirs stood at 89.08 per cent, indicating a steady improvement due to continued rainfall in the lake catchment areas. The highest rainfall during the last 24 hours was recorded at Tansa (124 mm), followed by Tulsi (118 mm), Upper Vaitarna (100 mm), Middle Vaitarna (97 mm), Modak Sagar (91 mm), Bhatsa (76 mm) and Vihar (46 mm).

Among the reservoirs, Modak Sagar, Tulsi and Vihar remain at 100 per cent capacity, while Tansa is nearly full at 99.58 per cent. Middle Vaitarna has reached 92.15 per cent, Bhatsa, the city's largest reservoir, is at 88.43 per cent and Upper Vaitarna has touched 80.14 per cent.

Four reservoirs have already started overflowing this monsoon. Vihar and Tulsi lakes began overflowing on July 7, while Tansa Dam overflowed on July 22 and Modak Sagar Dam on July 23.

With reservoir levels now exceeding 90 per cent, Mumbai's water supply remains in a comfortable position as the monsoon continues across the region. The city is expected to receive moderate rainfall and thundershowers this week, although no rain alert has been issued.

Gusty winds of up to 60 kmph are likely during intense spells, while the city's Air Quality Index stood at 32, remaining in the 'Good' category.

The improvement in water reserves is a welcome relief for the city, which has been facing water scarcity issues in recent years. The steady rainfall has helped to replenish the lakes and ensure a steady supply of water to the city's residents.

The situation will continue to be monitored by the Hydraulic Engineer's Department, which releases daily updates on the water stock levels. For now, the city's water supply remains stable, and the prospects of a comfortable water supply for the rest of the year look promising.

In conclusion, the crossing of the 90 per cent mark in Mumbai's water reserves is a significant development, and the city's residents can breathe a sigh of relief. The steady rainfall and overflowing reservoirs have ensured a comfortable water supply, and the city is well-equipped to handle any future water scarcity issues.
