KenK mentioned it in Marty's 'Irony' thread: No power for six days, the biggest problem was water for the horses. Horses drink a LOT of water... a friend once said an average horse drinks about 5 gallons per day just hanging around, more when working, and probably more in hot weather.
Also, horses can be rather finicky about their water.
So, your power is out, the electric well pump doesn't work, you can't use a hand pump because the source is 150' deep, you have no natural water source nearby and you have two regular riding horses.
First off, you need closed, portable containers. I have the feeling that one-gallon jugs aren't going to cut it. Some 50-gallon plastic barrels with lids might do (~450 lbs when full). Or one or two of those white plastic cubes contained in a metal frame that I occas. see in pickup trucks (~100 gals?).
Do they make heavy plastic bags like the Water BOBs, but to fit the beds of pickup trucks? (If they don't, they should.)
Then, where do you get the water?
If you're lucky, it's raining; just collect it.
If the power outages are spotty, someone you know will probably donate water. Here, the local feed store has a well, and the owner puts out a sign if she has power: "FREE water, bring your own containers".
If there is a stream/river nearby, is it clean enough? And you would probably need some kind of pump, but what does it run on?
What else?
