Thanks. I do already have a water bob, and already have bottled water, however i dont think its enough. I would like to have at least 4/5 , 5 gallon jugs of water stored. But i wasnt sure if all the generic jugs have to be dumped every 6 months or if theres longer lasting ones. At walmart theres 5 gallon jugs with water in them for $5 each, seems like a good deal but again i want it for long term so if the container is not bpa free then it wint help, just want to see if theres other options.I assume you are going to fill 5 gallon pails with water to have around for an emergency. You could go with food grade plastic pails. I get mine from a bakery, but I think you might get a taste infusing into the water. Others have talked about using milk jugs but I've heard that you can't clean them well enough, but as I said other says they have no problems. The research I've done says to dump the water every 6 months and refill. Personally I use bottled water and store in milk crates so I can stack them 6 high. Another possible idea is a "water bob".

Don't forget your hot water heater.
I have an office type cooler and the bottles do stack well but I have found over time the bottles do leak if left on their side for long periods of time.Maybe you should look into a "water cooler" type apparatus they have in offices... You could stack the full jugs on their side and then put them in the dispenser when you need them...
