BMC says rainfall improved water availability

The BMC said the latest rainfall has helped reservoirs recover after relatively subdued monsoon activity in June.

The civic body posted: “Due to the rainfall that occurred in the 24 hours from 6 a.m. on Tuesday, July 7, 2026, to Wednesday, July 8, 2026, the water stock in the 7 reservoirs supplying water to Mumbai has reached 41.36%. In the last 24 hours, there has been a 12.44% increase in the water stock in the reservoirs. Additionally, there has been a 24.44% increase in 48 hours,' the BMC posted.”

The seven lakes supplying Mumbai’s water needs, Bhatsa, Modak Sagar, Upper Vaitarna, Tansa, Vihar, Tulsi and Middle Vaitarna, are located across Mumbai, Thane, Palghar and Nashik districts and rely heavily on monsoon rainfall for replenishment.

Mumbai Weather Forecast: Rain Expected to Ease

According to the India Meteorological Department (IMD), rainfall intensity in Mumbai, Thane and nearby areas is expected to reduce over the next few days.

After a week of yellow and orange alerts due to heavy rainfall, Mumbai is expected to receive light to moderate rain between July 8 and July 11. No specific weather alert has been issued for the city during this period.

The IMD forecast said Mumbai will experience a “generally cloudy sky with intermittent light to moderate rain in the city and suburbs.” Maximum and minimum temperatures are expected to remain around 32 degrees Celsius and 28 degrees Celsius. The BMC has also confirmed that schools and colleges will remain open as no adverse weather conditions are expected.
