Major Thane Water Main Leak Repaired, Mumbai Supply Restored
A very big water pipe near Thane sprung a leak, and people in parts of Mumbai did not have enough water.
Workers found the leak on Thursday night.
At first, they put a wooden plug in the hole to stop the water.
To fix the pipe for good, they dug around it and pumped out the water.
They planned to weld a metal patch onto the damaged pipe.
But the water inside the pipe was under very high pressure, and the pipe burst open again on Saturday.
The engineers had to work very fast and carefully with pumping stations to lower the pressure.
They finished the permanent repair by 5:00 PM on Saturday.
After that, the pipe was carefully filled with water again, and homes got their water back in stages, starting that evening.
A massive 3,000 mm diameter Mumbai-III trunk pipeline leak near Three Hand Junction (Teen Hath Naka) in Thane was repaired on Saturday evening.
The leak was first detected on the night of Thursday, August 13, and was initially contained with a temporary wooden stopper.
A second breach caused by high internal water pressure occurred late Saturday, worsening water shortages before repairs were completed.
Engineers welded a mild steel (MS) patch plate onto the damaged steel conduit and stabilized the trunk main by 5:00 PM on Saturday, August 15.
Water supply to Mumbai city and the eastern suburbs was restored in phased stages starting at 9:00 PM Saturday.
