The first mistake households make with earthquake water storage is picking a barrel before picking a volume. A family of four following the standard one gallon per person per day for three days rule needs 12 gallons, while stretching that to two weeks pushes the requirement past 55 gallons and changes which container makes sense. Choosing the best water storage barrels for earthquake kits is a capacity decision first and a brand decision second.
Our team compared ten containers in this roundup rated from 4.2 to 4.6 stars, with review counts running from 459 to 3700. We focused on the details that decide whether a barrel works in a shaking house: how wide the fill opening is, whether a spigot is built in or has to be improvised, how the container behaves when full, and whether it can be strapped to a wall. Our broader emergency storage picks are collected in our water storage barrels for emergencies guide.
Two facts frame everything below. A full 55 gallon drum lands near 460 pounds, which means the storage location is a decision you make once and rarely revisit. And a rain barrel and a drinking water barrel solve different problems, even though they sit in the same aisle and cost a similar amount per unit of capacity.

1. Eagle Plastic Drum: the pick for a general-purpose drum
Eagle Plastic Drum, 55 Gallon Drum, DOT Compliant, Made in USA, Blue
55 gallon open-head drum
HDPE body
23.75 x 23.75 x 39.13 in
Pros
- Seamless one-piece body minimizes leak risk
- 4.6 stars across 2399 reviews
- Nestable tapered base saves storage space
- Removable lid with metal lever-lock
Cons
- Sold as an industrial spill drum rather than a drinking water barrel
- Bulkier 39 inch height than the 35 inch water barrels
This is the drum we kept coming back to while building the list. It weighs 19.21 pounds empty, stands 39.13 inches tall on a 23.75 inch square footprint, and holds 55 gallons of HDPE with no seams to fail. Buyers rate it 4.6 stars across 2399 reviews.
The removable lever-lock lid is the feature that matters most in a shaking house. You can open the drum, top it off, check the level, and close it in seconds without unbolting anything.
For earthquake use the tapered bottom is worth more than it looks. Nestable drums let you store empty units inside each other, so you can own two or three and still have a clear floor when they are dry.
The honest drawback is what it is sold as. This is a DOT compliant open-head drum marketed to people containing liquids and handling hazardous materials, not a certified drinking water barrel. If you fill it with tap water for drinking, treat the water at fill time.
A full drum belongs on a ground floor slab
At 55 gallons the filled weight lands around 460 pounds, and preparedness forums put owners between roughly 440 and more than 500 pounds on the same drum. Put it on a ground floor slab, in a garage or in a basement, never on an upper floor and never on a shelf.
Fill the open head with a hose, not a pump
The open head means a garden hose laid in the top reaches the bottom, which is far faster than trying to push water through a bung. Treat, seal the lever ring, and date the lid with a marker so you know when the last rotation happened.
2. BayTec 55 Gallon Water Barrel: the pick for drinking water
55 Gallon Blue Water Barrel | Solid Mold |2 Inch Bung Holes, Good for Long Term Drinking Water Use | BPA Free
55 gallon solid molded drum
BPA-free HDPE
23 x 23 x 35 in
Pros
- BPA-free and certified for long-term drinking water storage
- Pressure checked and leak tested before shipping
- Solid one-piece heavy-gauge molding
Cons
- New plastic odor needs bleaching or rinsing first
- Occasional scratches or dents from shipping
- Two small bung holes make cleaning slower
This is the drum we would fill from the tap for drinking. It is solid molded HDPE, BPA free, UN-DOT certified, and rated for long-term drinking water storage. Rating is 4.6 stars from 862 reviews.
The two 2 inch bung holes are threaded and wide enough to accept a standard bulkhead adapter or a pump inlet. Buyers praise the wide, well-threaded caps and report that the barrels arrive pressure checked and leak free.
Dimensions are 23 by 23 inches with a 35 inch height and 24 pounds empty, so it is nearly 4 inches shorter than the industrial drum above. That difference matters in a basement with a low ceiling.
Two caveats show up repeatedly in reviews. New barrels can carry a plastic odor that needs a bleach wash or a rinse before filling. Transit damage is also reported, with a small number of barrels arriving with scratches or dents.
Cleaning through two narrow bung holes
Plan on a hose and an adapter rather than pouring, and accept that full draining is slower than scrubbing. Tip the drum to reach the last of the water, then let it dry before the refill rather than reusing the first rinse.
Add chlorine treatment before sealing, which is the step preparedness forum users describe first, and mark the fill date on the lid.
What one 55 gallon drum actually covers
One drum holds 55 gallons, which is close to 14 days for a family of four at the one gallon per person per day baseline, or three days for a household of roughly 18. Add pets, infant formula and medical needs and the real figure shortens.
3. WaterPrepared 55 Gallon Stackable Tank: the pick for tight floors
WaterPrepared 55 Gallon Unique Stackable Utility Water Tank, Blue
55 gallon stackable tank
Polyethylene body
28 x 22 x 29.5 in
Pros
- Stacks securely to save floor space
- Fits through a standard doorway
- Brass spigot accepts standard garden hoses
Cons
- Some units arrive with plastic shavings to vacuum out
- Spigot sits low so a stand helps bucket filling
- Heavy and awkward once full
Stackability is the whole idea here, and it is the reason this tank solves the problem forum users describe over and over, namely that indoor storage space is the binding constraint. The oval body measures 28 by 22 by 29.5 inches, and a second unit sits on top with about 4 inches of clearance needed underneath the upper tank.
Owners of this tank rate it 4.6 stars from 783 reviews. Buyers call out the brass spigot, which connects to a standard garden hose and outlasts the plastic valves on most garden barrels, plus the large fill cap and the fact that the tank passes through a standard doorway on delivery day.
The UV-proof plastic blend is marketed as slowing bacterial growth in stored water, which matters if the tank sits in a garage with a window. Material is FDA approved for potable water contact according to the manufacturer.
A few units arrive with plastic shavings or chips inside that need vacuuming out before filling, and the spigot sits low enough that a stand makes bucket filling far easier. Owners using these tanks for well and off-grid water have posted about placement in basements, garages, sheds and conditioned crawl spaces.
How to measure the stacking clearance
Measure the second tank position before you commit. You need roughly 4 inches of vertical room above the lower unit, a flat slab underneath, and a wall to strap the stack to so a full upper tank cannot walk off in a tremor.
Where the brass spigot earns its keep
Hose compatibility means one container can serve a garden, a washing machine or a car while a second is being filled. If you plan to draw water into buckets mostly, budget for a stand, because the outlet is low on this model.
4. Augason Farms 55 Gallon Barrel: the pick for a simple sealed reserve
Augason Farms lon Water Storage Barrel – BPA-Free Plastic Barrel 55-Gallon
55 gallon drum
Food-grade BPA-free plastic
22.95 x 22.95 x 35.13 in
Pros
- Meets FDA food contact specification
- No plastic smell reported
- Lightweight at 18 pounds empty
Cons
- Sealed top with two access holes is awkward to fill
- No built-in spigot so you need a siphon or hose
- Some reports of the bottom ballooning in extreme cold
Augason Farms is a long-established preparedness brand, and this drum is built for that audience rather than for gardens. It is food grade and BPA free, meets the Food and Drug Administration specification for food contact, and rates 4.6 stars from 689 reviews with owners frequently mentioning the absence of a plastic smell.
At 18 pounds empty and 22.95 inches square by 35.13 inches tall, it is one of the lighter 55 gallon drums on this list, which makes it the easiest to reposition before you fill it. Weights matter here because the filled unit is effectively permanent.
The trade-off is access. The top is sealed and offers only two built-in plug fittings for filling and draining, so cleaning means working a hose and a brush through two holes. There is also an internal lip that keeps a small amount of water from draining out completely.
There is no built-in spigot at all. You will be running a hose or using a siphon pump, and a few owners report the bottom ballooning outward in extreme cold, so keep it in a conditioned space rather than a shed in a freezing climate.
Deciding between a bung fill and a siphon
If you are comfortable with a fixed hose and a pump, the two plug fittings are fine and the sealed top is a genuine contamination barrier. If you want to draw water casually during a shutdown, this is the wrong drum and the BayTec above is the better fit.
Cold weather placement
Reviews flag bottom bulging in extreme cold, so treat this as an indoor or garage container in regions that freeze. Rattling during shaking is the other risk, and a strap to a stud or a wall anchor closes that gap cheaply.
5. RTS Home Accents 50 Gallon ECO Rain Barrel: the pick for outdoor collection
RTS Home Accents 50-Gallon ECO Rain Barrel Made with 100% Recycled Plastic, Flat Back Rain Water Collection Barrel, Black
50 gallon capacity
Recycled UV-resistant polyethylene
24 x 19 x 34 in
Pros
- 3700 reviews give it the widest owner feedback base in the roundup
- Flat back sits flush against a wall
- Built-in overflow valve links barrels
Cons
- Flat back can bow out and warp under a full load
- Plastic spigot gaskets can dislodge and leak slowly
- Must be drained before freezing weather
This is the container with the most owner feedback in the roundup, with 3700 reviews and a 4.3 star average. It ranks first in the rain barrel category, and the flat back sits flush against a house wall, which is what side-yard and garage placement needs.
Capacity is 50 gallons at 18 pounds empty, measuring 24 by 19 by 34 inches. The contoured top funnels water toward a mesh debris screen, and a built-in overflow valve lets you link multiple barrels in series.
Two structural complaints repeat in reviews. The flat back can bow outward under a full 50 gallon load and stay warped, which matters if you plan to lean the barrel or rely on the stand sold separately, and the included plastic spigot is a weak point where gaskets can dislodge and cause slow leaks.
It is made from 100 percent recycled polyethylene, which is a genuinely useful material for utility water and outdoor exposure but is not the same certification as a food grade drinking barrel. For drinking, treat it or use a certified container instead.
Linking barrels for a bigger reserve
The overflow valve and linking path mean a second barrel drains into the first rather than spilling. Size the run on how much roof area feeds it, and remember the whole assembly has to be anchored and kept level once filled.
What happens in freezing weather
Reviews are explicit that this barrel must be drained before freezing conditions or it can split. That rules it out as a permanent year-round reserve in cold regions unless it sits in an unheated but protected space above freezing.
6. FCMP Raincatcher 4000: the pick for fast filling and easy cleaning
FCMP Outdoor Raincatcher 4000 Rain Barrel, Flat-Back Rainwater Catcher with Spigots, 50 Gallon, Brown – Portable Water Storage Container Tank for Home, Garden, and Backyard
50 gallon capacity
UV-inhibited BPA-free polyethylene
24 x 24 x 32 in
Pros
- Largest top opening in its category for hand filling and scrubbing
- Series linking spigots scale up storage
- Complete kit with hose screen valve and overflow
Cons
- Included flat overflow hose is often kinked or collapsed
- Overflow hose is too short to reach the ground
- Spigot flow is weak without a stand
The wide top opening is the story here. Buyers single it out as the easiest barrel in the category to fill by hand, scrub and inspect, and the flat back accepts a downspout directly against the house. It holds 50 gallons and measures 24 by 24 by 32 inches.
The rating is 4.5 stars from 3151 reviews. Side spigots let barrels connect in series, and the kit includes a 40 inch garden hose, debris screen, shut-off valve, hanging clip, overflow tube and a linking kit.
Material is UV-inhibited BPA-free polyethylene, and owners report the body stays rigid outdoors over seasons. The wide mouth also catches free-dripping roof water without a full gutter connection, which is useful when the gutter is the part of the roof that broke first.
The single most repeated complaint across reviews is the included flat overflow hose, which arrives kinked or collapsed and is commonly replaced with PVC. The hose is also too short to reach the ground on many setups, so plan the routing before you rely on it.
Downspout hookup and overflow routing
Trace the overflow path from the stand to a drain before the first storm. A 50 gallon barrel accepts a lot of roof water fast, and an unplumbed overflow is what floods a foundation or a garage floor.
When collected rainwater stops being drinking water
Roof water carries dust, debris, insects and roofing residues, so treat this as utility supply for laundry, cleaning and toilets. For drinking, fill a certified food grade drum from the tap instead.
7. RomoTech 50 Gallon Square Tank: the pick for secure transport
RomoTech 82123919 50 Gallon Square Polyethylene Water Storage Tank
50 gallon square tank
Rotomolded UV-stabilized poly
36 x 19 x 22 in
Pros
- Rotomolded body holds its shape without bulging when full
- Molded gallon graduations read the level without opening
- Tie-down channels accept saddle straps
Cons
- Some units arrive with a leaking or cross-threaded drain fitting
- Outlet sits high so a little water stays trapped
- Large and awkward to return
This tank is built for movement, and that is the angle that matters in earthquake country. Rotationally molded medium-density polyethylene gives it a body that holds its shape when full instead of bulging, and molded tie-down channels accept saddle straps for a truck bed or trailer.
It holds 50 gallons at 25 pounds empty, and the square profile is 36 by 19 by 22 inches, so it fits crosswise against a wall where a round drum will not. Owners rate it 4.5 stars from 903 reviews.
Two details make it easy to live with. Molded gallon and liter graduations mean you can read the level through the translucent walls without opening the lid, and a 5-1/2 inch screw lid with a 5 inch opening makes filling and cleaning straightforward.
The drain fitting is the recurring problem. Some units arrive with a leaking or cross-threaded bulkhead, and the 3/4 inch NPT outlet is not positioned low enough to empty the last couple of inches, which matters for anyone rotating the full volume.
Securing the tank in a trailer or truck bed
Use the molded channels with ratchet straps crossing the body, not just the neck. Add a low anchor point so a full tank cannot slide forward under braking or lateral shaking.
Reading the level without opening the lid
The graduations save you from lifting a screw lid in the dark during a shutdown. Pair them with a small flashlight and you can judge remaining supply from across a room, which is faster than filling a bucket to check.
8. FCMP Slim Line 45 Gallon Barrel: the pick for narrow side yards
FCMP Outdoor Slim Line Design Rain Barrel, 45 Gallon, Brown
45 gallon slim-line barrel
UV-inhibited BPA-free poly
22 x 16 x 32 in
Pros
- Slim 16 inch depth fits spaces other barrels cannot
- Flat back sits directly against the house
- Complete kit with hose overflow and linking parts
Cons
- 45 gallon capacity is below the 50 and 55 gallon sizes
- Molded wood-grain plastic can crack in cold climates
- Included hardware is basic next to premium kits
Depth is the number that matters with this one. At 16 inches deep and 22 inches wide, the rectangular profile is the narrowest barrel on this list, which is the answer for the side yard between a house and a fence where nothing round will fit.
It holds 45 gallons and weighs 20 pounds empty, with a 4.3 star average from 1055 reviews. The wood-grain styling is moulded into the body so the barrel reads as garden decor rather than a drum, and the flat back sits right against the house wall.
Side spigots allow several barrels to be connected in series, and the kit includes a garden hose, a shut-off thumb valve, a hanging hose clip, an overflow hose and a linking kit. Owners value having the whole kit in one box.
The trade-offs are honest ones. Forty-five gallons is ten gallons short of a full 55 gallon reserve, and reviews note the moulded wood-grain plastic can crack or weather over time in cold climates.
Fitting a barrel into a narrow side yard
Measure the gap at the narrowest point and add clearance for the stand and the fill lid. At 16 inches of depth, this barrel fits spaces where the round 23 inch models cannot be positioned at all.
What you give up at 45 gallons
A household of four at the one gallon per person per day baseline needs 4 gallons a day, so this covers roughly 11 days for four people. If you are targeting a full two weeks, you need two units or a larger drum.
9. Laspeiraux 53 Gallon Collapsible Tank: the pick for people who cannot store a barrel
Collapsible Rain Barrel Water Storage Containers 53 Gallon
53 gallon collapsible tank
Three-layer PVC
23.62 x 23.62 x 27.56 in
Pros
- Folds flat for storage and transport
- Weighs 5.7 pounds empty
- Integrated screw-in spigot
Cons
- Soft sides suit temporary capture better than long-term drinking storage
- Body can slump and lose rigidity when full
- Needs a level base to stay upright
This is the container for the constraint forum users hit most often, which is that a rigid drum simply cannot live inside the home. At 53 gallons, three-layer PVC and 5.7 pounds empty, this tank folds flat and disappears into a closet between uses.
It rates 4.2 stars from 459 reviews, the smallest review base in the roundup. It also carries the lowest average rating of the ten, which makes sense once you understand the design: it is built for portability rather than for a decade of shelf life.
The integrated screw-in faucet avoids multi-part faucet assembly, and circular footpads stop the barrel wobbling on a patio or slab. A mesh top filter blocks leaves and limits overflow when you are catching roof water. It is also available in 105 gallons.
The limits are structural. Soft-sided construction is a poor match for long-term potable storage, the shape can slump when full, and the small mesh openings can still admit insects, so plan on disinfection before drinking.
Storing a full cistern in an apartment
This is the container that works when weight and floor space are limited, because empty it is thin and light. In a high-rise, a full 53 gallon unit still weighs around 450 pounds, so it belongs on the ground floor where the structure can carry it.
Whether soft PVC suits drinking water
Treat this as a temporary or seasonal reserve, not a five year supply. Rigorously prepared households pair a collapsible capture vessel with rigid certified barrels for the drinking reserve.
10. Good Ideas Nantucket 50 Gallon Barrel: the pick for a visible front yard
Good Ideas Impressions Nantucket Rain Water Collection Barrel, 50 Gallon
50 gallon capacity
Durable polyethylene
23.25 x 23.25 x 32 in
Pros
- Decorative 4 inch planter top looks intentional outdoors
- Two metal spigots outlast plastic valves
- Routed overflow channel protects the foundation
Cons
- Planter top adds weight that weighs down the lid
- Heavier than a basic utilitarian barrel
- Slow weeping at some spigot threads
The distinguishing feature is a 4 inch planter-style top that turns the barrel into part of the landscaping. If the container will sit in view from the street, that is the difference between a drum in the garden and an object you chose.
It holds 50 gallons and measures 23.25 inches square by 32 inches tall, with a 4.4 star average from 539 reviews. Buyers single out the two metal spigots, one at the front for a hose and one at the side for filling tall buckets, as more durable than the plastic valves on most barrels.
The second spigot doubles as overflow control or as a link point for another barrel, and a routed channel diverts overflow to the front so water is directed away from the foundation. A mesh screen blocks debris, and the product carries a one year limited manufacturer warranty.
The trade-offs are added weight and care. The planter top has to be kept from overfilling or its weight pulls down on the lid, and a small number of owners report slow weeping at the spigot threads over time.
Appearance in a visible front yard
If the barrel is seen from the house, this styling removes the main objection to outdoor storage. In a garage or side yard, a plain drum leaves more room for a second certified drinking barrel.
Planter care and winterizing
Keep the planter soil light or use a shallow seasonal planting, and drain the barrel before freezing weather. A full barrel with wet soil in the top is a heavy object sitting on the lid, which is the part least designed to carry that load.
How Much Water Do You Actually Need
Start with the standard baseline, one gallon of water per person per day, and multiply by three days for the minimum recommended reserve. Then extend for the scenario you actually face.
Pick the duration first. Three days is the minimum recommendation. Fourteen days is the figure used in earthquake country guidance for regions where water mains and supply lines can stay down.
Multiply by the number of people. A family of four needs 4 gallons a day, so 12 gallons for three days and 56 gallons for two weeks.
Add roughly one gallon a day for pets, and allow extra for infants, formula, medical needs and cooking.
Round up to the nearest container count. Two weeks for four people plus pets lands near two 55 gallon drums.
A 55 gallon barrel is not a small purchase, since it is close to a two-week supply for a family of four with nothing else in the house. One drum is a starting point for many households rather than a finished plan.
Rain Barrel or Drinking Water Barrel: Pick the Right One
A rain barrel collects and stores water for non-drinking uses, while a drinking water barrel holds treated tap water sealed against light and contamination. They are different products with different jobs, and the overlap is where most wasted purchases happen.
Use a rain barrel for garden irrigation, car washing, laundry, toilet flushing and cleanup water. It is built wide and open for fast filling, has a debris screen for leaves, and usually includes an overflow hose and linking kit. That hardware is meant to sit outdoors through a season of weather, not to keep a drinking supply sealed.
Use a food grade, certified drinking water barrel for anything you or an infant will swallow. That means threaded or lever-lock sealing, BPA-free HDPE, no screened open top, and ideally a built-in spigot so the water is never scooped from a wide mouth with a household dipper. Our rain barrel guide for gardens covers the outdoor collection side in detail.
One more category worth naming: dedicated water storage tanks with larger capacities and no collection hardware at all. If your well or off-grid system needs buffering rather than earthquake reserves, our water storage tank picks for well systems cover that class.
Where a Full Barrel Goes in an Earthquake Home
A full 55 gallon drum weighs around 460 pounds and cannot be repositioned by one person, so choose the location before you fill it. Ground level, on a slab, is the only sensible answer for most homes.
Keep it low. A garage floor, basement slab or a ground floor utility room beats any shelf, and upper floors are worth avoiding entirely because of live load during shaking.
Strap or anchor it. Use steel strapping to a stud, a wall anchor or a floor-mounted tie-down point so a shifting barrel cannot roll into a doorway or tip onto someone.
Leave the valve accessible without moving anything. If the spigot is buried behind the barrel, you will find out how inconvenient that is during a blackout.
Set it where you can reach it from the ground. A low spigot saves you from tipping a 460 pound object to get a bucket under it.
Check the floor. Older slabs and some decks are not designed for a stationary 460 pound point load, so distribute or relocate if in doubt.
Tip-over is the single most earthquake-specific risk with a full barrel, and it is the one nobody in the editorial guides we reviewed mentions. Strapping costs almost nothing and removes it.
How to Fill, Treat, and Rotate a 55 Gallon Barrel
The forum consensus is consistent and simple: buy a food grade container, treat the water at fill time, and rotate the inventory about once a year. Nobody in those threads dumps 55 gallons; they cycle it.
Wash first. Dilute unscented bleach in water, scrub the interior, rinse, and let it dry fully. New plastic barrels often need this more than old ones.
Fill with potable tap water only. Rainwater and well water need disinfection before they go in a drinking barrel.
Add treatment. Follow the label on chlorine dioxide or unscented bleach for the volume, and mix it through the full contents rather than pouring it in one spot.
Seal and date the lid. A marker on the lid gives you an honest rotation date without opening anything.
Rotate by cycling. Keep more than one container, drink or use the oldest first, and refill that container instead of emptying a fresh one.
Pair with a filter. Preparedness communities consistently treat a filter as the backup for tap water that becomes questionable after a main break.
Users on preparedness forums describe sanitizing drums with pool shock, rotating everything at least yearly, cleaning with bleach and drying before refilling, and keeping purification tablets on hand as a backup.
Frequently Asked Questions
How much water should be included in an earthquake kit?
Federal guidance calls for one gallon of water per person per day for three days, which is three gallons for each person. A household of four needs 12 gallons for that minimum. Earthquake regions push well past the baseline: two weeks for four people is 56 gallons, or one 55 gallon barrel plus a smaller container.
How long can you store water in a 55 gallon drum?
Treated water in a properly sanitized food grade container is generally considered good for one to two years, and up to five years when treated with a chlorine product and kept cool and dark. Untreated water should be swapped about once a year. Preparedness users rotate the whole inventory annually and wash with bleach before refilling.
What is the best container to store water for emergency purposes?
A rigid food grade HDPE barrel with a threaded or lever-lock sealing lid is the most dependable choice. It will not crack, it nests or stacks when empty, and it can be anchored to a wall. Collapsible cisterns are convenient to store but are a poor match for multi-year drinking water reserves.
How long will 50 gallons of water last for a family of four?
Fifty gallons divided by four people is 12.5 gallons each. At the one gallon per person per day baseline that is 12 days of drinking, cooking and hygiene water for a family of four. Once pet water, infant formula and medical needs are counted, the realistic figure drops closer to nine or ten days.
Are rainwater barrels safe for drinking?
Rain barrels are not designed for potable water. Roof water picks up dust, animal droppings, insects and roofing residues, and the plastic resin can leach into stored water. Use collected rainwater for laundry, cleaning and toilets, and keep a sealed, treated food grade barrel as the drinking reserve.
Our Verdict for Earthquake Water Storage in 2026
For most households the best water storage barrels for earthquake kits come down to two questions. Do you want certified drinking water storage, in which case the BayTec 55 gallon barrel is the direct fit, and do you have a tight floor, in which case the stackable WaterPrepared tank does more with the same footprint. The Eagle drum is our overall pick for sheer durability and depth of owner feedback, with the caveat that it is a general-purpose drum rather than a certified drinking barrel.
Pick your capacity with the one gallon per person per day formula, fill it before you need it, anchor it to the wall, and date the lid so you know when to rotate. That single afternoon of work covers the item in your kit you cannot buy after the shaking stops.
