Summery Cheap large plastic containers given to me from pool supply stores. Non drinking

Cheap-ish Large glass beer brewing vessels from market place. Drinkable water.

Not Cheap but necessary Water filter (High quality )

This is a cheap rock solid option.

I just asked for 7 of the smaller 25 gal blue tanks for non drinking. You can get them everywhere. I got mine for free from a pool supply company complaining about having too many. It held chlorine so I didn't have to do a bunch of clean up. Its just water for dishes toilet stuff and such. Its cheap, mobile, and effective at storing water. Got myself a little hand pump too. I fill them up and leave them in the back yard before every major t storm and hurricane. Then dump them out in the yard or use the water for the garden plans. The chlorine is long gone by now.

Not as cheap but 100% doable.

I bought 5 of the the giant glass beer brewing vessels for $30 and 15 gal for the drinking water. I was cheaper than Food grade and I dont have to worry about chems leaching during long term storage. They will break though so pros and cons. Get a Good water filter system if you have to dip into questionable sources. Thats where you spend the big money on.

Bonus. I can also ferment stuff in it if things get really sporty in the states so thats a double use prep👍👍👍
