It seems that due to the extreme weather a lot of water pipes have burst in Northern Ireland leading to a lack of fresh water of any kind. This has apparently been going on for up to 8 days in some parts.

They are having to set up areas for bottled water for people to drink and places for people to go to be able to wash. This could turn into a major health issue if supplies are not restored.

Frankly, I'm surprised by just how quickly this occurred and how little the response has been since it started.
