In a further post from the Witney MP at 20:30 GMT, a Thames Water worker said: “We’re hearing people are experiencing low pressure, not really no water at the minute.”
The Liberal Democrat added: “Over in Eynsham, there is a diver in a crater right now… and they’re putting a collar round the pipe.”
In a statement, Thames Water said: “We are very sorry for the disruption this incident is causing and understand how worrying and inconvenient this situation will be for customers affected.
“We’re currently responding to a critical burst water main in a field next to Oxford Road, OX29.
“This 800mm main feeds the reservoirs that supply… postcodes OX7, OX18, OX28, OX29, GL7.”
In a later update, external at 21:30, the firm said: “The damaged section of pipe has now been successfully isolated.
“Our crews will be working overnight to carefully excavate around the damaged section of the 800mm main so that permanent repairs can be safely carried out.”
