The Chem-Tainer 1550 Gallon Plastic Vertical Liquid Storage Tank is a polyethylene vertical tank built for bulk liquid storage, water reserve, and the kind of standing-volume jobs where you need a lot of capacity on a compact pad. It holds 1,550 gallons on a square 87.0 x 87.0 inch footprint, so the base it needs is the same dimension all the way around. Full of water it carries roughly 12,927 pounds, and it is rated to a specific gravity of 1.5, which means the shell is engineered to hold contents up to about 19,390 pounds at maximum rating. That SG 1.5 rating is the headroom that lets this vertical storage tank do more than just water.
Will it work for your job
For water storage this tank is straightforward: 1,550 gallons of usable volume on a square 87 x 87 footprint, with a full-water load just under 12,927 pounds that your pad and base have to support. Confirm the slab or compacted base is level and rated for that weight before you set it. For exact overall height and the fitting and outlet placement, see the technical drawing on this page and confirm the dimension against your install clearance before you order. If you are sizing a reserve for irrigation, a larger storage program, or a private fire-water supply, run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide so the gallon target and footprint match what your site can actually hold. For a remote or rural reserve, our fire-water reservoir design guide walks the NFPA 22 sizing discipline.
The 1.5 specific gravity rating is the detail people miss
The common mistake on a vertical storage tank this size is treating the specific gravity rating as a formality. At SG 1.5 this shell is rated for contents heavier than water, but that rating is the ceiling, not an invitation to ignore it. Match your stored liquid's specific gravity against the 1.5 number, and never put a liquid denser than the rating in the tank. Just as important: a tank rated for a given density is not automatically rated chemically for a given fluid. This tank is documented for water service, so for any liquid beyond water, confirm material compatibility before you fill it. The full-water figure of 12,927 pounds and the max-rated 19,390 pounds are both load facts your foundation needs to clear.
Freight and ordering
This tank ships LTL freight from Chowchilla, CA, the nearest named plant for this model, and freight is quoted live to your ZIP rather than included in the list price. It moves as an 87-inch-wide single oversized unit, so get your freight cost up front with the Freight Cost Estimator before you order. For a side-by-side on how this brand stacks up in the larger vertical-tank class, the Snyder vs Norwesco vs Chem-Tainer comparison is worth a read, and our deeper 1550 gallon vertical storage tank buyer's guides (here and here) walk the full spec set; note they cite an 87 x 67 dimension, so verify the exact height against the on-page drawing before you build out the install. Questions on fit, footprint, or freight to a specific ZIP, call 866-418-1777 and we will size and quote it with you.
