The Chem-Tainer 1550 Gallon Plastic Vertical Liquid Storage Tank (SKU TC8765IA) is a natural-white polyethylene vertical tank built for bulk water and liquid storage where you need real volume without a footprint blowout. It stands 65 inches tall on an 87 x 87 inch base, holds 1,550 gallons, and carries a 1.9 specific gravity rating. That 1.9 rating - paired with the "IA" in the SKU - means this is the heavy-wall build, not the standard 1.5 SG water-tank wall, so you are getting a thicker, more durable tank than straight water storage requires.
Will it work for your site?
Plan your pad and plumbing around the real numbers. The footprint is 87.0 x 87.0 inches square, so confirm you have an 8-foot-square spot of level, fully supported base before delivery. Filled with water this tank carries roughly 12,927 pounds of contents; its wall is rated to a maximum contents weight of 24,561 pounds at 1.9 specific gravity, so the structure has wide margin on plain water. That weight is why the base matters - a polyethylene vertical tank must sit on a continuous, flat, load-bearing surface (compacted pad, concrete, or engineered ring), never on point supports or uneven ground. If you are still settling on capacity, run your daily draw and refill cycle through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to this size.
A low-profile vertical, and the durability you paid for
At only 65 inches tall on an 87-inch square base, this is a deliberately low-profile vertical storage tank - a strong pick for height-restricted installs like under eaves, inside structures, or in enclosures where a tall vertical will not clear. It fits under low overhead but needs a wide, square pad, so check the 65-inch height and 87-inch width against your actual install rather than ordering on gallons alone. The 1.9 SG heavy wall is not wasted on water service either: the thicker wall buys longer service life and more impact and UV margin, and leaves headroom to repurpose the tank later for heavier liquids (verify chemical compatibility before any such service). This is the white vertical storage tank that handles non-potable water, irrigation reserve, and rainwater collection, and if you are building a private fire reserve our guide on fire-water reservoir tank design walks through NFPA 22 sizing and freeze protection for cold-climate sites.
Fittings, and how to compare before you buy
Fitting and outlet configuration - bulkhead fittings, gasketed outlets, and lid - is confirmed at order on a tank this size, so call 866-418-1777 to spec your outlet size and placement before the tank ships, and review the technical drawing on this page so your supply and discharge plumbing lines up. If you are weighing brands at the larger end, our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison breaks down how the major polyethylene makers stack up, and for a deeper walkthrough of this exact 1,550-gallon size see our 1550 gallon vertical storage tank buyer's guide (65 inches tall, 87-inch square base).
Freight is the single biggest cost variable on a tank this size, and this one ships LTL from one West Coast plant - the Chem-Tainer facility in Chowchilla, California - quoted live to your ZIP. Run your number in seconds with the Freight Cost Estimator or call 866-418-1777, and flag accessorials up front (liftgate, residential, limited-access) since those drive the final number. We will confirm the nearest stocking plant and lead time before anything ships.
