Atlanta is currently suffering from a major water main break that has put half the city under a boil-water advisory. The city government is reportedly bringing in pallets of bottled water, so there hopefully will not be any real crisis here. But I expect this will be a wake-up call for a lot of people who have not given much thought to prepping.

There are also major droughts in Mexico City and Bogota, threatening to dry out their taps.

Do you all have any tips for folk with how to prep for loss of water service, especially for folk in cities where they may not have a ton of storage space or land for collecting water?

I'll start off by referring to the US FEMA guidelines: One gallon of water per person per day. In my experience the best format is those upright 1-gallon bottles with the opening in the top middle (not the milk-jug style with the handle).
