Going to be having our water cut off for 72 hrs because our water plant has been flooded

I've got some water in a bucket and some big bottles filled up. There's already been fighting in near by Tesco's and the police are monitoring the bigger stores as people do stupid things. Also might have our electrity cut off tonight.
At least my place isn't flooded so I'm very grateful for that but this is going to have a big knock on effect for so many things now. When our water gets reconnected there's a big chance it will be badly contaminated as well.
