Local to me there's been an incident where groundworkers have damaged the main water supply- the schools had to close due to no water, and the residents living within a 2 mile radius had to collect bottled water from the leisure centre where they set up a 'hub'.
This did take a few hours to get up and running and the water was out for a few days.
Not everyone has the ability or knowledge to purify water for consumption.
If it gets to the point where we can't filter water due to some other reason then unfortunately it will be a grave situation which a lot of us are unable to prepare for short of owning a bunker
Did anyone go thirsty ? Did anyone have 'no' water ?
We live in a civilized country, none of us lives so remote that there is no way to get supplies as necessary.
It's scale again. Tide you over for a little while, and it'll be fine.
Like power cuts
