Best 5-gallon rectangular water jugs for camping and emergency water supply

Top pick: Saratoga Farms 5-Gallon Stackable Containers (20-gallon kit). These are the rectangular, stackable kind you asked for — HDPE, with lids, spigots, a wrench and water preserver included, so you can line them up in a closet or garage and draw water without lifting. Best for a real household emergency stash.

Who the others suit:

• 5-Gallon Stackable Water Container (single): buy one at a time to top up a kit you already have.
• UPWOIGH 5 Gallon Jug: a single jug with a pump — handy for a camp kitchen.
• Scepter military-style cans: tough and well rated, but they're jerrycan-shaped, not rectangular — better for truck bed or tailgate hauling.
• Collapsible containers (Alexapure, Coghlan's): pack flat for camping, but they don't stack and can split over years of storage.

For a fixed emergency supply, go rigid and rectangular; for camping trips, a collapsible one saves space.
