Thames Water has said that homes affected by a mains burst in Reading should be re-connected in a matter of hours.
The company said it has received almost 1,000 complaints from customers in the area this morning.
Water supplies are set to be restored in the next few hours to most of the customers in and around south Reading whose supplies were interrupted by a burst main early this morning.
"We have turned off water running through the broken pipe and we are now re-routing water to the affected areas from other parts of the network.
"Water pressure is now starting to build back up in the network and by mid afternoon normal service should have been restored to most affected customers in the RG2 and RG7 postal areas.
Meanwhile our engineers are digging out the broken section of pipe to replace it. The main, which takes treated water from Reading's main water works to Earley storage reservoir, burst at 4.30am.
“By 10am we had received 900 reports from customers in the RG2 and RG7 postal areas with either no water or low pressure.
“We are sorry to everyone affected by this.”
