The Chem-Tainer 1500 Gallon Vertical Liquid Storage Tank is a white polyethylene vertical tank built for bulk water and liquid storage where a tall, small-footprint vessel makes the most of limited floor space. It holds 1,500 gallons in a 64-inch diameter footprint and stands 127 inches tall - about 10 feet 7 inches - so it stores serious volume on just over five feet of ground. This is the kind of vertical storage tank that anchors a rural water supply, an irrigation reservoir, a fire-water reserve, or any 1500 gallon liquid storage job where you need height instead of sprawl.
Will it work for your site?
Confirm three things before you order: footprint, water weight, and the liquid you plan to store. The footprint is 64.0 x 64.0 inches, and you need a level, fully supporting pad under the entire base - a vertical tank standing nearly 10 feet 7 inches is unforgiving of an uneven or partial foundation. Filled with water this tank carries roughly 12,510 lbs, so the pad and any structure beneath it have to be rated for that load plus the tank's own weight. The shell is rated to a 1.5 specific gravity, which means it is built to carry a liquid up to one and a half times the weight of water - a maximum rated contents weight of about 18,765 lbs. That leaves roughly 6,255 lbs of weight headroom over plain water, so if you later store a denser liquid the shell has the structural margin for it (chemical compatibility is a separate question the SG rating does not answer). Run the numbers for your site with the Tank Sizing Calculator, and if you are still choosing a size, the Tank Sizing Guide walks through capacity, height, and footprint trade-offs.
Fittings and configuration
The outlet, lid, vent, and overflow sizes and locations are not pre-specified in this listing - read them off the technical drawing on this page, or call 866-418-1777 to confirm the as-shipped configuration before you order. Match your plumbing and any connections you add to that drawing so your outlet height, manway, and connection sizes line up with your pump and piping plan. If you are designing the vent for an enclosed or actively filled installation, our worked guide on atmospheric vent capacity calculations for polyethylene storage tanks covers the API 2000 inbreathing and outbreathing math for 1,500-gallon and larger verticals.
The mistake to avoid
The most common error on a vertical tank this size is the foundation. A 1,500-gallon vertical standing nearly 10 feet 7 inches puts enormous concentrated load on its base and is sensitive to tilt - a pad that is slightly out of level or that settles unevenly can stress the tank wall. Pour or place a full-diameter, level, load-rated pad and verify it before you fill. The second mistake is reading the 1.5 specific gravity rating as a license to store anything: that number tells you the shell can carry the weight of a heavier liquid, not that the polyethylene resin is chemically compatible with it. For water, irrigation, rainwater, and fire reserve, this tank is squarely in its element. If you want the full sizing and configuration walkthrough, the 1500 gallon vertical liquid storage tank buyer's guide is a useful next read.
