"Southern Water is repairing damage caused by the replacement of Victorian water mains ten years ago."
But I take your point, although if it's damage that was caused 10 years ago and it needs resurfacing now can it have been that bad?
So it's to do with replacing the Victorian water mains 10 years ago? From what I can recall they said that work was meant to mean Southern wouldn't need to work on it for another 50 years or something? That panned out well.
