Best Large Water Storage Containers & Tanks

Updated Oct 20, 2026 ยท 2 picks ยท Prices checked Oct 20, 2026

Once you move past a few jugs, the question becomes where to put the water. A household of four at one gallon per person per day needs about 56 gallons for two weeks, which is exactly what a 55-gallon drum or tank holds. The WaterPrepared stackable tanks we list are food-grade, BPA-free HDPE and appear on The Prepared's shortlists; the 160-gallon version takes less floor space than three separate drums. If you rent or live in an apartment, WaterBrick-style stackable containers slide into closets and under beds and are easier to carry. Keep big tanks off bare concrete, out of sunlight and away from fuel or chemicals. Have a siphon or pump ready, and refresh self-filled water every six months as FEMA recommends.
