Work to replace a pipe in Cassington left more than a dozen homes without running water yesterday.
Thames Water was carrying out the work on behalf of a developer.
It had written to 12 properties beforehand saying they would temporarily be without water but the work affected about six more homes in the area from 10.50am, for almost an hour and a half.
Thames Water spokeswoman Becky Trotman said: “There was a slight problem in that it knocked out the supply to a few more properties. The job is finished now and water should be running again.”
