# Grocery store bottles or one jug you refill

> A case of bottles you already bought counts as stored water. A refill jug is easier to pour from at home, and owning both is a fine plan.

Part of the [Water](https://bordernest.com/silo/water.md) guides.

If there is a case of water on the floor from the last storm or forecast, drink it or date the plastic and leave it where it sits. That is stored water, and it counts toward your household supply even if it came from the grocery shelf rather than a survival catalog. Bottles are easy to hand to someone walking out the door, which is why I keep a flat in the trunk of the car and a few extras by the front door. A jug, on the other hand, is what I would park in the kitchen or pantry and refill from the tap every time it empties, because the handle and the spout make pouring into a pot or a glass far less annoying than wrestling with a flimsy 16 ounce bottle.

The reason both forms belong in the same house is that they solve different problems. Single serve bottles are grab and go, and they are already paid for, so they are a sunk cost that doubles as a small emergency reserve. A refill jug is the daily driver, the container you actually drink from during a normal week, which means it gets rotated without you having to think about it. The habit that ties them together is simple: when you crack the last bottle in a case, write the month and year on the cap with a marker, and when the jug is empty, refill it the same day rather than letting it sit dry for a week.

Do this today: walk to wherever your spare water lives and write today's date on the cap of the oldest bottle or the side of the jug with a permanent marker. That single act turns a pile of plastic into a rotating supply you can read at a glance, and it is the same habit you will use for every other container you bring into the house.

**Reliance: Reliance Aqua-Tainer 7 Gallon.** The jug you refill from the tap, parked in the kitchen so it becomes the daily driver.

Once a jug is in the house, the next habit is dating it so you actually rotate it, and that is where the overview picks up. Open Start with water, before you buy anything clever to see how the jug fits into the full household plan.
