Thames Water: Reading, Pangbourne and Tilehurst residents without water
Some residents have been left without water for a third day after "technical issues" at a water treatment works.
About 900 customer in Reading, Pangbourne and Tilehurst are affected.
Thames Water said although the fault was resolved on Saturday, airlocks in its mains pipes meant properties in the RG1, RG30 and RG31 postcode areas were still experiencing problems.
The water firm apologised and said it hoped supplies would be "back to normal in the coming days".
A bottled water station was set up at Tesco Extra on Napier Road in Reading but Thames Water said supplies had run out by lunchtime on Monday.
It said further supplies would be available soon and the station would remain open until 21:00 GMT.
A second bottled water station which will also be open until 21:00 is open at Meadway Sports Centre, Conwy Cl, Reading RG30 4BZ.
Maiden Erlegh School in Reading closed on Monday, with students learning from home, as it has also been affected by the lack of water.
Berkshire Healthcare NHS Foundation Trust said Prospect Park Hospital also lost running water for more than three hours on Saturday night.
The psychiatric facility, in Reading, is still experiencing issues with water pressure and has been provided with additional water by Thames Water while it tries to resolve the problem, the trust added.
A Thames Water spokesperson said the water issues happened after "technical issues at our Pangbourne Water Treatment Works, which were resolved on Saturday afternoon".
They said: "Since that problem was resolved on Saturday, we have struggled to rebuild water pressure due to more than 10 burst mains caused by the recent cold weather.
"We have over 50 engineers in the area fixing leaks and removing airlocks from our network."
"Both the bottled water stations at Tesco Extra on Napier Road and Meadway Sports Centre on Conwy Road, Reading, will remain open until 9pm and will re-open tomorrow at 9am. "
"We're really sorry to customers in the Reading, Pangbourne and Tilehurst areas who are experiencing no water or low pressure, due to airlocks in our mains pipes."
