The WaterBrick Stackable Water Container is the best food grade water storage tank for most households because its 3.5 gallon bricks stack like cinder blocks, weigh under 30 pounds full so anyone in the house can move them, and use thick BPA-free HDPE that will not split in a closet or truck bed. Emergency guidance calls for one gallon per person per day for at least three days, and modular containers hit that target without the handling problems of giant tanks. The Reliance Aqua-Tainer remains the value standby, and a 55 gallon barrel covers serious long-term storage.

How We Chose These Water Filters Picks

We compared wall thickness, plastic type, stacking behavior, and full-container weight across the widely sold food grade options, then reviewed owner feedback on leaks, spigot failures, and long-term taste. Containers earned ranking only if they use food grade HDPE and seal reliably through months of storage.

Key Takeaway: Store water in containers you can actually move. A 55 gallon barrel holds the most, but at over 450 pounds full it never leaves the basement, so pair bulk storage with smaller grab-and-go containers.

Best Overall: WaterBrick Stackable Water Container

WaterBrick Stackable Water Container

Best for: Households building a real emergency water supply that needs to fit in closets and garages, and anyone who cannot safely lift a full 7 gallon jug. Why it made the list: Each brick holds 3.5 gallons, about 29 pounds full, stacks interlocked like masonry up to several layers, and the thick HDPE walls tolerate freezing expansion and rough handling that split thinner jugs.

  • Key specs: 3.5 gallon capacity per brick, food grade BPA-free HDPE, interlocking stackable design, molded handle, wide opening compatible with optional spigot lids.
  • What we like: The weight is manageable for nearly every adult, the bricks stack stable and dense against a wall, and the wide mouth makes cleaning and refilling far easier than narrow-neck jugs.
  • What we do not like: Cost per gallon is the highest here, the standard cap has no spigot so pouring means lifting or buying the spout lid separately, and building 50 plus gallons takes a lot of bricks.
  • Who should buy it: Families storing two weeks of water in normal living spaces, apartment preppers, and anyone prioritizing carryable units over bulk volume.
  • Who should avoid it: Buyers wanting maximum gallons per dollar, a Reliance jug or a 55 gallon barrel stores water far cheaper if handling weight is not a concern.
  • Common complaints: Owners mention the included cap requires a wrench to seat fully airtight and that stacks above four high should be strapped, both fair handling notes rather than defects.
  • Size note: Each brick is roughly the size of two stacked shoe boxes, measure closet depth and remember a family of four needs about 12 gallons for a three day supply.
  • Cleaning note: Sanitize before first fill with a teaspoon of unscented bleach per gallon of rinse water, swirl, and air dry upside down.
  • Alternative: The Augason Farms 55-Gallon Water Storage Barrel stores bulk volume cheapest per gallon if you have a permanent spot and a siphon pump.

Food Grade Water Storage Buying Guide

What food grade actually means

Look for HDPE containers stamped with the number 2 recycling code and sold explicitly as food grade or water storage containers, which means the resin and any additives are approved for contact with drinking water. Never repurpose barrels that held industrial liquids or detergents, the plastic absorbs chemicals that no amount of washing removes. Blue coloring is the industry convention for potable water and also limits light penetration.

Size against realistic needs and real muscles

Plan on one gallon per person per day, with three days as the floor and two weeks as a comfortable target. Then be honest about weight: water runs 8.34 pounds per gallon, so a 7 gallon jug is 58 pounds and a 55 gallon barrel is over 450. The right answer for most homes is a mix, bulk barrels that stay put plus bricks or jugs someone can carry to a car.

Storage conditions and rotation

Keep containers off bare concrete on boards or pallets, away from direct sunlight, and away from fuel or solvents whose vapors can migrate through plastic over years. Municipally treated tap water stores well sealed, rotate it every six to twelve months, or treat with a measured dose of unscented bleach for longer cycles. Label every container with the fill date.

Safety Notes

  • Use only unscented household bleach at proper dilution for sanitizing and treating, scented or splashless versions contain unsafe additives.
  • Never store water containers near gasoline, pesticides, or solvents, vapors permeate HDPE over time.
  • Strap or limit stack heights, a falling 29 pound brick or toppling barrel causes real injuries.
  • If stored water smells odd, looks cloudy, or the container bulges, purify it or discard it rather than tasting.

What to Avoid

  • Repurposed milk jugs, the plastic biodegrades and the caps never seal, most start leaking within months.
  • Non-food-grade barrels from industrial or unknown sources.
  • Storing a single giant tank as your only supply, you cannot move or transport it in an evacuation.
  • Clear containers in lit spaces, light feeds algae growth.

FAQ

How long can you store water in a food grade container?

Water itself does not expire, treated tap water in a sanitized, sealed food grade container stays safe for six to twelve months without attention, and longer with proper bleach dosing or purification tablets. Taste can flatten over time, pouring between containers re-aerates it.

Do I need to treat tap water before storing it?

Municipal tap water already contains residual chlorine and can usually be stored as-is in sanitized containers for six months. For longer storage or well water, add unscented household bleach at the standard rate of about two drops per quart, and label the container with the date.

Can I stack water storage containers?

Only containers designed for it, like WaterBricks, which interlock and carry stacking loads through their structure. Standard jugs like the Aqua-Tainer will bulge and eventually split if you stack them full, and 55 gallon barrels should stand singly on a pallet.

Final Verdict

The WaterBrick Stackable Water Container is the best food grade water storage tank for household use, stacking dense while staying light enough to carry, with the Reliance Aqua-Tainer 7 Gallon delivering the most affordable spigot-ready storage and the Coleman 5-Gallon Water Carrier covering budget kits and camping duty.
