Storing large amounts of drinkable water, best methods?

  • 🐕 I am attempting to get the site runnning as fast as possible. If you are experiencing slow page load times, please report it.
I see those clear jugs at Home Depot all the time, but realistically how long does the water stay drinkable in those clear plastic jugs?
The clear PETG (same material as the little water bottles) ones start deteriorating pretty quickly, I wouldn't drink it after 6-12 months. The more robust containers last longer but I still recommend rotating water every 6-8 months.
 
There are gravity water filters you can buy that filter the water and can hold gallons. I recently got one and it's great. Buy a bunch of extra filter replacements ahead of time and get some steel water barrels or large class water/drink holders to put extra in. If you live somewhere you can put rain barrels out to collect to filter or have some sort of lake or creek nearby you could collect from that would be good too. Even if you life in the city I could see maybe stealthily putting out some buckets to collect rain water or if possible hang a trough out the window like you would window flowers but use it to collect rain water instead.

The nice steel water filters can be pricey but worth it IMO.

Canned water said to last 50 years. I want to get a bunch and put in the car and storage and forget about them.

There are many different chemical ways to preserve water over longer periods. Potassium permanganate, chlorine and silver but I don't think any method is set and forget but require cycling but with longer periods between cycles.
At BLUE CAN Water in Los Angeles, CA, our mission is to provide long-lasting, great-tasting, emergency drinking water in aluminum cans.
This is why your unimpaired circulation is already over, drinker. Enjoy sludging.

Too bad the price makes it cost prohibitive to actually stockpile a meaningful amount of water.
