There are companies that can water for people in emergency situations, but I doubt that it costs $2.50 a can. I have had water in 2 liter bottles and have had several fail on me. Probably better than the milk jug type, but my recycling bin has been filled a few times recently with all of them. They were in plastic bins with lids, which was for safety measure, but plastic breaks down, sooner or later. But so do aluminum cans. I buy Santa Cruz lemonade which comes in 32 ounce glass bottles. I wash the bottles and refill them with water. They are heavier to deal with and I am always on the search for good storage bins to hold them. I found that there are wooden crates at Joann's that will hold a dozen, but the crates are around $12 a piece. I also have 55 gallon drums, 6 and 7 gallon camping jugs, and several of the plastic 5 gallon jugs for water coolers. I remember when the 5 gallon bottles were only in glass, and you can get glass ones for brewing, but I am not going to get a bunch of them. If I can find a couple for a good price, I would go that route. I prefer glass to plastic for everything, but it is heavy and more expensive.
Are those 55 gallon drums, or more like a 12 ounce can? I can't tell the size.
12 ounce can or there-about.
I never thought of mylar bags for water storage.
They are in a box with a spout.

I've had many of them fail. But, the leaks are immediate upon delivery, right from the get-go. What might be only a small drip when the bottle is still capped quickly becomes a flood once the cap is removed and air gets in to replace the vacuum that was holding the water in previously. I've never had one that was not leaking initially and then later developed a leak - except when they are dropped, especially when it is very cold outside - that tends to nuke 'em real fast. Even if the water inside hasn't frozen yet, the plastic hardens when cold and becomes more brittle. Those bottles seem quite heavy duty when empty, but they are not when full. Treat them with care.
Is it really "sterile"? Highly doubtful. "Filtered" does not mean "sterile".
I had delivery briefly from Deep Rock, and their bottles seemed strong. I have seen bottles in the grocery store that were thinner plastic.
Did you read the instructions of how she did it? It is not filtered. Go back and read how she canned them.
Deep Rock is the specific company I was talking about who delivers my water (makes sense, since you and I live in the same area with the same vendors). They deliver me about 3 or 4 leakers per year, and my order volume is two bottles every two weeks. That's a good 5% of my deliveries that will leak (and the leaks are coming from small holes and cracks in the bottles). We should realize though, that companies like Deep Rock use the same bottles multiple times. We all hope they clean them out well between customers! If we were to buy brand new never-used bottles then the leak percentage might go down markedly.
I have never had a leaker, but it has been a few years since I had water delivered. I wonder if the quality of the bottles is not as good as they once were.
I see it says: "...is naturally filtered and purified as it passes over and through the volcano’s geological formations", that seems to imply that the water is "naturally pure", whatever that means.
In order to use sterile water for something like a wound packing or cleaning, you'd also have to have a sterile field to do the dressing change with. You'd need sterile gloves, sterile gauze, sterile syringes, etc. If you had all of that, you likely had sterile saline to use as well. However, in a SHTF situation, you're probably going to aim for clean conditions vs. sterile conditions just b/c a sterile environment is going to be nearly impossible out in the field.
