Storing water for years is not the same as buying a big jug. The containers that actually hold up are built from food-grade plastic, seal with real gaskets and fittings instead of snap-on lids, and block light so nothing green grows inside. Get one of those and water you filled two years ago still pours clear. Buy the wrong one and you get a leaking barrel in the garage and a plastic taste you cannot rinse out. This guide sorts the seven picks that hold up best.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Capacity, plastic type and fitting size matter more than any label, and the picks below cover every scale from a single pantry shelf to a full emergency system. Every one of these Long Term Water Storage Containers is food-grade, but they size up very differently for a family.
Top Picks
How To Choose The Best Long Term Water Storage Containers
Start with the plastic, not the size. A container meant to sit full for two years has to be food-grade, and it has to keep light out. Those two things decide whether your water stays drinkable or turns cloudy and plasticky.
Food-grade plastic and light blocking come first
Every pick here is made from BPA-free, food-grade polyethylene. BPA-free means the plastic does not leach bisphenol A, a chemical you do not want sitting in drinking water. Food-grade means the material is rated to touch what you consume.
Color does real work too. A dark blue or opaque exterior limits the light that reaches the water inside. Light feeds algae and bacteria, so a light-blocking tank on a garage shelf or in a shaded spot keeps water fresher far longer than a clear one.
Size the capacity to your household
One 55-gallon barrel holds about 11 days of water for a single person, which is the number owners repeat most often when they talk about these drums. A family of four needs to think in multiples, not in ones.
Smaller 15 and 20-gallon options fit where a 55-gallon drum cannot. They also split the weight, which matters because a full 15-gallon container lands near 125 pounds.
Weight and placement decide where it lives
Water is heavy and the container is only part of the load. A barrel that seems easy to move when empty becomes fixed furniture once it is full. Plan the spot before you fill it, and keep the barrel out of direct sunlight.
Fittings, spigots and siphon hoses matter more than you think
Getting water out is half the job. A 2-inch bung fitting takes a pump or a siphon hose, while a threaded spigot lets you pour straight into a cup. A bung wrench helps you tighten and loosen the cap without fighting it.

Detailed Reviews
1. Augason Farms Water Treatment and Storage Kit, 55-Gallon
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The drum you buy once, fill, and forget for six years.
Most barrels ship as an empty shell and leave you to source the pump, the wrench and the water treatment. This kit shows up ready to go: a 55-gallon BPA-free drum, two 2-inch barrel plug fittings, a 6-foot siphon hose with a hand pump, Aqua Mira treatment bottles, and a pail and barrel opener. The whole thing weighs 27 pounds empty, compared to the 125 pounds the 15-gallon container above carries once full. Nothing about a 55-gallon drum is light, but getting it into place before you fill it is the easy half of the job.
What wins people over is the drum itself. Owners who stored this drum outside under a tarp for six years report emptying it with the hand pump and finding the barrel still clean enough to refill. The polypropylene body arrives new and undamaged, without the “do not reuse” stamps and chemical residue that follow secondhand barrels around. One flaw hides in the kit rather than the drum: the plastic hand pump is the weak link, so treat the siphon as your everyday backup and the pump as a convenience.
Then there is the one honest catch — you have to open the second port to let air in while you pour, or the water glugs out slowly. Value is the most-discussed topic on this listing, and it splits both ways: some buyers call it money well spent, others feel they paid over the odds. Look past that and the hard part is done in one purchase. If you want the treatment, the hose and the wrench bundled with a drum that has already proved itself outdoors, this is the sensible place to start.
What comes in the box
- Complete kit: drum, two 2-inch plug fittings, 6′ siphon hose with hand pump, Aqua Mira drops, and a pail and barrel opener.
- Holds 55 gallons — roughly 11 days of water for one person.
- BPA-free food-grade polypropylene drum with a 5 gpm maximum flow rate.
- Long outdoor track record: one owner emptied six-year-old stored water and refilled the same drum.
Where it asks patience
- Crack the second port open for airflow or water pours slowly.
- The included plastic hand pump is the flimsiest piece; the siphon hose is the sturdier fallback.
- Value divides opinion, so know what you plan to store before you commit.
Buy this one if: you want a single purchase that covers a full 55 gallons plus treatment, hose and wrench with no extra shopping.
Look elsewhere if: you would rather source your own pump or you need a container you can shift around once it is full.
2. 15-Gallon Stackable Water Storage Container with Siphon Hose
A barrel small enough to move, big enough to matter.
Fifteen gallons sounds modest next to the 55-gallon drums here, and it is — the Augason kit holds 3.7 times as much. But a 15-gallon container reaches places those drums cannot. It stands 21.5 inches tall on a 15.7 by 15.7 inch footprint, so it tucks into a closet, a basement corner or an RV bay without a fight. The trade-off is weight: filled, this one lands near 125 pounds, while the 27-pound Augason drum weighs a fraction of that before you add water. That comparison is the whole decision in a nutshell — bigger drum, heavier barrel, and this is the lighter, smaller option.
Owners rate the build highly, and the twin pour and vent spouts with 2-inch bung fittings (large threaded openings) and rubber gasket seals are why. Those gaskets keep a full barrel tight and dry over long stretches. The dark blue exterior also blocks light, just like the dark tanks from Legacy Food Storage above. Buyers report storing bleach-treated tap water in two of these barrels for two years in a cool dry basement and finding it still fresh and clear, with the seal holding tight.
The honest catch is the stacking claim in the name. Reviews suggest it does not stack well because the handles get in the way — think of this as a sturdy single barrel, not a stacking system. One practical tip from the field: when it is full you will want a hand cart, since lifting it is a two-person job. And the siphon it ships with does more than pour — you have to draw half the water out before the barrel is light enough to tip.
The build quality stands out: dark blue light-blocking food-grade plastic, dual 2-inch bung fittings with rubber gaskets, two heavy-duty carry handles, and a 6.5 ft self-priming siphon hose with a copper head and a bung wrench included.
The honest workaround: it weighs about 125 pounds full, so plan its spot before you fill it and keep a hand cart nearby, because the barrel itself will not move easily once it is loaded.
Reach for this if: your storage space is tight or you want a container a senior can handle without wrestling a 55-gallon drum.
Think twice if: you plan to stack several — the handles block that, and the weight makes each one a set-and-stay fixture.
3. 55-Gallon Water Storage Barrel Blue
An industrial drum that earns its keep indoors and out.
This is the barrel for the buyer who wants one sturdy drum and nothing else. The Hoank holds a full 55 gallons in a heavy-duty high-density polyethylene body built from HMWPE — that is high molecular weight polyethylene, the same family of plastic used for impact-resistant outdoor tanks. It is UV-stable and weatherproof, so it shrugs off sun and rain without fading or cracking and holds up in harsh conditions where a cheaper drum would not. Dual 2-inch NPT and buttress fittings mean you can attach a pump or hose on either side.
What wins people over is the build. It is UN-rated for safe storage and transportation of regulated materials, which is real certification, not a marketing word, and it makes the drum as useful for dehumidifier water as for an emergency supply. Buyers describe filling one with water captured from a dehumidifier and finding it solid, sturdy and exactly as advertised. It is a tidy industrial option for anyone who wants a barrel that functions as well in the garden as it does on a shelf.
The catch is a fixed top. The tight head design is what keeps it leak-proof, but it means no wide opening — if you need to reach inside, you will be cutting the lid. One buyer did exactly that and called the drum great otherwise. Set that against the design and it is a fair trade, because a sealed tight head is precisely what stops a 55-gallon container from seeping over months of storage.
What the drum is built from: a 55-gallon HDPE body rated UV-stable, weatherproof and impact-resistant, with dual 2-inch NPT and buttress fittings and UN certification for regulated storage.
The one fixed-top catch: the tight head design is smooth and leak-resistant, but it means no removable lid.
Best matched to: an outdoor or utility setup where a single strong drum handles water, dehumidifier output or rain, with fittings ready for a pump.
Not the pick for: anyone who needs to get their hand to the bottom of the barrel.
4. Legacy Food Storage 5 Gallon Water Tank 4-Pack
Four tanks that stack into a pantry and pour like a pitcher.
Instead of one heavy drum, this set splits the load. You get four 5-gallon tanks for 20 gallons total, each one 15 by 10 by 15 inches and about 40 pounds when full. That is the difference between a barrel nobody can lift and four containers a person can actually carry one at a time. Stackable ribs on top lock each tank into the one above it, so the set turns a closet corner into usable storage instead of a floor-hogging block.
Each tank has a wide 2¼-inch opening and ships with five full sets of ¾-inch threaded sealed caps plus a spigot with prepared caps, so you can keep one tank as the dispenser and stack the rest behind it. Where the single 55-gallon barrel above holds all its water in one place, this set spreads it — one tank stores on the shelf while another pours into your cup from the spigot, and you can rotate stock tank by tank rather than dumping and refilling 55 gallons at once. For a household that wants a reasonable reserve without dedicating half a garage to it, 20 gallons across four containers is a practical, manageable amount.
The honest word of caution is leakage. Most buyers get tight, dry tanks, but a share report water seeping from the spout even with the cap tightened down. Screw everything in firmly, test each one before filling, and the set does its job. Tanks arrive odor-free and clean, and when a set showed up missing the spigot and wrench, customer service answered quickly and sorted it inside minutes — so the support is there when something is off.
The stacking advantage
- 20 gallons split across four 5-gallon tanks — about 40 pounds each when full, so they stay liftable.
- Stackable ribs lock the tanks into place for pantry, garage or storm-shelter storage.
- Wide 2¼-inch opening, five sets of ¾-inch threaded sealed caps, and one spigot for easy pouring.
- Odor-free on arrival and the plastic is food-grade, BPA-free HDPE with a light-blocking dark blue exterior.
What to watch
- Sealing is the weak spot: some splits leak from the spout even when capped tight.
- Test every tank and cap before you commit water to it.
Suits a household: that wants a real 20-gallon reserve without lifting a 125-pound barrel or giving up garage floor.
Think twice if: you want zero fuss getting water out and every drop sealed on the first try.
5. 55 Gallon Blue Water Barrel | Solid Mold | 2 Inch Bung Holes
The plain, rugged barrel that does the job without extras.
This BayTec barrel is what a drum looks like when it is built to work and nothing else. A solid-molded high-density polyethylene body, UN-DOT certified for storing liquids, with two 2-inch bung holes for filling and draining. It measures 23 by 23 by 35 inches — the tall, round shape that fits under shelves or alongside a garage wall — and weighs 24 pounds empty. It is pressure checked and leak tested before it ships, and the same food-grade plastic can hold oil or serve as a rain barrel, so it stays useful even when it is not holding drinking water.
Owners point to the looks and the sturdiness more than anything. It arrives clean inside and out, ships fast with accurate tracking, and buyers who order several report no leaks and a solid build. That said, treat the surface gently: because it ships bare with no box or covering, it can pick up a few scratches or some dust in transit, which wipes off and does not affect the barrel at all.
Two small quirks turn up in the feedback and both have easy fixes. The inside can carry a faint chemical smell when new — a rinse with bleach water clears it, and owners who did that report the smell fully gone before refilling with filtered water. Getting both 2-inch ports open also takes a bit of effort the first time, so have a tool on hand. Value is debated, with some finding it a fair deal and others feeling it sits on the high side, but the barrel itself holds up well enough that the drum outlasts the argument.
Built to keep water in: solid-molded HDPE, UN-DOT certified, pressure checked and leak tested, with two 2-inch bung holes for filling and draining.
Handle the first fill with care: the new interior can carry a faint odor until you rinse it with bleach water, and the bung fittings need a tool to open cleanly the first time.
Worth picking if: you want a certified, leak-tested 55-gallon drum with plain bung holes and no kit to unpack.
Look elsewhere if: you mind a raw barrel that shows up unboxed and might need a wipe-down.
6. Augason Farms 55-Gallon Water Storage Barrel
The lightweight shell of a barrel, ready for your own plan.
Eighteen pounds empty is the headline. That is the lightest 55-gallon drum on this list — the kit version above weighs 27 pounds in its P7 form — so moving this one into place before you fill it is genuinely manageable. Round it out with the basics: a BPA-free food-grade plastic body, a full 55-gallon capacity, and two built-in plug fittings for filling and draining. For a basement or garage that needs dependable backup supply, the food-grade drum gives you a clean place to keep water ready for drinking, cooking and hygiene during an outage.
The build is where buyers put their trust. A tight lid, no smell, and a durable barrel that owners expect to hold water for years without contamination — that is the consensus. The model name carries the same reliability as the treatment kit above, and households that stockpile jugs of drinking water often graduate to a drum like this for the volume. Fitting it into a shelf, though, is where the details bite: with a fixed inner lip, fully cleaning a 55-gallon drum is awkward, and emptying the last of the water is fiddly. Adding a spout or a siphon hose — the same idea as the siphon hose the 15-gallon container above ships with — is the workaround.
For the price and the bare-bones approach, the barrel delivers what it promises: storage, not a kit. It ships plain, so you source the pump, hose or fittings yourself. That is either a feature or a hassle depending on how you tackle projects, but the drum itself is solid and worth the spend once you commit to it.
Light and simple: an 18-pound, BPA-free food-grade 55-gallon drum with two plug fittings and a tight, odor-free lid.
You bring the rest: no pump, hose or treatment included, and the fixed inner lip makes deep cleaning and full draining awkward.
Pick this if: you want a straightforward 55-gallon food-grade drum and plan to add your own pump or siphon.
skip it if: you would rather everything — treatment, hose and all — arrive in one box.
7. WaterPrepared 55 Gallon Stackable Utility Water Tank, Blue
A 55-gallon tank engineered for tight spaces and stacking.
Most 55-gallon tanks are round and space-hungry. This one is shaped to fit through a standard doorway and stack with a gap for airflow, so two of them can share a footprint that would hold one ordinary drum. It is made from polyethylene, runs on a spigot that connects straight to standard garden hoses, and the UV-proof plastic helps stop bacteria from building up in stored water. Where the fixed-top Augason barrel makes deep cleaning awkward, this tank’s large fill cap and hose-ready spigot keep access simple.
The size and layout are what hook people. It arrives fully assembled, stands compact where an old horizontal drum rack once sat, and stacks securely. Owners set it up for well and power outages and report it filling, stacking and sealing without leaks, with clear directions in the box. It is also a favorite for a saltwater mixing station — a job where 55 gallons of stored water and a hose connector are exactly what you need. The same shape that makes it stackable makes it easy to carry and move when empty, which is not true of most 55-gallon containers.
Two facts to know going in. Installing a full tank outdoors is a serious job — owners describe cleaning plastic shavings out first and then building a stand so the low ground-level spigot sits at a usable height, plus a sun cover for a shady spot. And treating the water inside requires gloves and a short wait after adding the chemical. Neither is a defect; it is the nature of a 55-gallon tank. Get the placement right and the layout pays you back every time you fill a hose.
Engineered for placement: a stackable polyethylene tank that fits through a standard doorway, with a large fill cap, a spigot that takes garden hoses, and UV-proof plastic shielding the water.
Plan the install: the spigot sits low, so many owners build a stand, and chemical treatment calls for gloves and a short wait.
Ideal for: anyone stacking 55 gallons at a time in a garage, a shed or a saltwater mixing corner with hose access.
Rethink it if: you want a fill-and-forget barrel with zero setup, since this one rewards a careful install.
Know the Specs
Capacity in gallons
Gallons tell you how long the water lasts. One 55-gallon barrel covers about 11 days for a single person, a number owners repeat most when sizing a supply. Multiply that for your household: a family of four needs many times a single drum. Smaller 5, 15 and 20-gallon containers exist for tight spaces and easy lifting, but they cover a shorter stretch. Pick the emptiest corner you have and size up to it — a full barrel takes up far more room than the empty shell suggests.
Food-grade, BPA-free plastic
BPA-free means the plastic does not contain bisphenol A, a chemical you do not want leaching into drinking water. Food-grade means the material is rated for contact with what you consume. The drums here are built from high-density polyethylene, polypropylene or polyethylene — the same sturdy plastics used for jugs and barrels that last years. Light blocking is the partner spec: a dark or opaque exterior stops the light that feeds algae and bacteria inside a stored tank.
