Mumbai Lake Levels Water Supply Rainfall Water

As torrential showers battered Mumbai city, Tulsi and Vehar – two of the seven lakes which cater to the city’s potable water supply – received significant rain. In the past 24 hours ending at 6.00 am on Wednesday, over 263 mm rain was recorded over Tulsi lake while 142 mm rain was recorded over Vehar Lake.

Situated within Mumbai’s Sanjay Gandhi National Park belt, Tulsi and Vehar, however, only account for two percent of the total drinking water supplied by the seven lakes.

The seven lakes – Tulsi, Vihar, Tansa, Middle Vaitarna, Upper Vaitarna, Bhatsa, and Modak Sagar – have a total holding capacity of 14.47 lakh million litres. Of these, Tulsi holds 8,046 million litres of potable water, and 27,698 million litres is held by Vehar at its full capacity.

On Wednesday, heavy downpour eluded the interior regions wherein the other lakes are situated.

While Upper Vaitarna catchment area received no rainfall between Tuesday and Wednesday, 13 mm rain was recorded over Middle Vaitarna reservoir, 32 rain was received over Modak Sagar, 68 mm over Tansa lake, and 70 mm over Bhatsa reservoir.

“While the coastal region receives heavy downpour, most lakes are situated in the interiors, and concerns remain as this year, there is forecast of below average rainfall,” explained an IMD official.

After heavy spells across the city, the total stock in seven lakes on Wednesday plummeted to 1.14 lakh million litres which accounts for 7.94 percent, marking a drop from Tuesday when the stock touched 8.07 percent of the total holding capacity.

With lake levels remaining low, Mumbai will continue to reel under a 10 percent water cut while 20 percent cut is enforced across construction and commercial sites. “We will be closely monitoring the situation. Any further decision on more cuts will be taken after evaluating the rain forecast and lake levels by month end,” said a source.
