The link for day 1 is no water for a day. We did this for real 2 years ago when our well collapsed, and it took a week to get a new one in. Luckily it was smooth sailing, including flushable toilets due to elevated rainwater tanks, showers with the solar shower bags (heated outside then hung from the shower head in the house) It also demonstrated to my wife the value of prepping.
I'll have to look at the rest of the week to see how we would do.
