Why we pack it
Sally and Justin Steele, from our own trips
The Scepter water can earns its spot as our top pick for rigid water storage because it solves the fundamental problem of getting clean water to remote campsites without compromising on durability or taste. We have personally used these cans for years and they have survived being dropped off tailgates, baked in desert sun, and frozen in mountain winters. The military did not adopt this design by accident. Paired with the thread adapter and a brass valve, you have a gravity-fed water system that takes 30 seconds to set up and zero batteries to run. The only reason not to buy one is if you need something that packs flat.

About the Scepter BPA Free Military Water Can - 5 Gallon (20L)
The Scepter Military Water Can is the gold standard for rugged, portable water storage at the campsite. Built to military specification MIL-C-53109 and made in Canada from BPA-free high-density polyethylene, this 5-gallon (20-liter) container is virtually indestructible. Its stackable design, integrated carry handle, and screw cap with built-in vent make it efficient to transport and pour. Unlike collapsible bladders, it stands upright, resists punctures, and keeps water tasting clean trip after trip. The only trade-off is its rigid shape takes up space when empty.

Questions (5)
- Why do I need a thread adapter?
- Scepter water cans use metric threads on the spout (they are Canadian military spec). US garden hose fittings, brass valves, and pumps use 3/4-inch NPT threads. The thread adapter converts metric to NPT so you can build a gravity-fed or pumped water system.
- How long does water stay fresh in the can?
- In a clean, sealed Scepter can stored out of direct sunlight, water stays potable for approximately 6 months. For longer storage, add water treatment drops or replace the water periodically.
- Can I stack them when full?
- Yes, the flat-sided design is specifically made for stacking. You can safely stack 2-3 full cans. Make sure they are on a stable, level surface.
- Is it worth the price over a cheap water jug from Walmart?
- If you camp regularly, absolutely. Cheap jugs crack, leak, and impart plastic taste within a season or two. The Scepter is a buy-it-for-life product that military forces rely on. The durability and BPA-free construction pay for themselves over time.
- What accessories do I need to build a gravity water system?
- At minimum: the Scepter thread adapter (metric to 3/4 NPT), a brass shut off valve, and optionally garden hose quick connectors for easy hose swapping. Elevate the can on a table or tailgate and gravity does the rest.
