Best Ways to Store Water Long-Term—What’s Actually Safe?

[OrbitJazz21]

Looking to dial in my water storage plan and hoping for some up-to-date input. There’s a ton of info online, but it’s all over the map—bleach, food-grade barrels, mylar bags, even glass jugs. Some folks swear by rainwater collection, others lean hard into filling up every bathtub in the house at the first sign of trouble. What’s actually safe (as in, doesn’t breed funky stuff after a year or two) for long-term storage, especially if you’re off-grid?

I’ve been looking at 55-gal HDPE drums and WaterBricks, both labeled food-safe. But I’m hearing mixed things about plastic leaching if they’re stored in a hot garage. Is keeping ’em in the basement enough, or does heat wreck the storage?

On the chemical side—how much bleach per gallon really keeps it safe, and are there non-chlorine alternatives for folks with sensitivities? Would love to hear what folks have actually used for 1+ years without issues,

Basement is way better than a hot garage—heat definitely speeds up plastic breakdown. I use food-grade HDPE drums, rotated yearly, and add 1/8 tsp regular bleach per gallon. Have you tried iodine tabs?

Heat is definitely the enemy with plastic—basement is always my pick, even if it’s a tad damp. I trust food-grade HDPE but keep mine covered and out of sunlight. I’ve used unscented bleach for years at the standard 1/8 tsp per gallon and the water’s always tasted fine after a quick airing out. For chemical sensitivities, I’ve heard good things about colloidal silver drops, but haven’t tried them myself. Has anyone here actually used glass jugs long-term, or does sealing get tricky?
