You know those big bags that you can put in a tub and fill up for emergencies? That's great but if you don't have time to prepare before something happens, like a earth quake all of a sudden it doesn't help much. So, would it work to take a device like that and fill it up, add the right amount of bleach, seal it up and cover with a blanket to keep the sun off of it and store it long term? Like if you have a spare tub that is never used. I'm trying to figure out ways to get my dad and sisters family some water storage, they live by a creek but at certain times of the year it runs dry. Does anyone know of a way to store water long term using simple and cheap containers? Old jugs and 2 liter bottles are great but could take a while to save up. Anyone know of a good way to get used containers online that don't require a second mortgage on the house? Has anyone ever tried a 5 gallon bucket with a food grade bag of some sort lining the bucket? I'm sure there are tons of things I have never thought of, that's why I love places like this forum.
