A few years ago we put together an emergency water supply. We thankfully haven't needed to use it, but it is a good idea to have one in case of a natural disaster or city water emergency.
I didn't want to use plastic to store our water in, so we collected as many glass apple juice containers as we could. The water in these jugs should be changed occasionally, so to remember to do so I change it out with the seasons, thus we put fresh water in four times a year. The water in the jugs does not go to waste, it will be used to water plants, inside or out, or to fill the washing machine.
Anybody else have an emergency water supply? How do you store or manage yours?
