The flood which caused a major road in south London to close last night was the result of a burst water main which had mixed with mud and silt, Thames Water said.
Social media was awash with pictures showing the murky water flowing down Clapham Road in Kennington, south London.
Initial reports suggested that a sewage pipe had sprung a leak, with one policeman at the scene describing it as a "stinky sewage".
However, a Thames Water spokesman later confirmed that the flood was a result of a burst water main, which had mixed with silt and mud.
