The Snyder Industries 550 Gallon Vertical ASTM Tank is a free-standing polyethylene reservoir molded in high-density linear polyethylene (HDLPE), rated to 1.9 specific gravity, and finished in opaque white. At 64 inches across the base and 47 inches tall, it stores 550 gallons inside a 64.0 x 64.0-inch footprint, which makes it a low, stable vertical tank rather than a tall column. That 47-inch height is a real planning advantage: it clears most 8-foot doorways, low ceilings, and overhead obstructions that a tall column of the same volume would not, so it fits basements, low pump houses, and shipping containers where headroom is the constraint. Snyder builds it to the ASTM standard for polyethylene upright storage tanks, and you can confirm the wall and fitting layout against Snyder's product documentation before you order.
Will it hold what you need it to?
Plan around weight, not just gallons. Filled with water this 550-gallon vertical tank carries roughly 4,587 pounds; its 1.9 SG rating means the shell and base are engineered to support up to about 8,715 pounds of contents at the maximum rated density. That headroom is what separates a true 1.9 SG vertical tank from a light water-only drum, and on this tank the 1.9 rating is the heavy-duty tier in the lineup. If your service is water-only, that rating is structural margin you can lean on; if it is a density-heavy liquid, this is the rating you must not drop below. Use the Tank Sizing Calculator and the Tank Sizing Guide to match your drawdown and fill cycle to the 550-gallon working volume, and size everything downstream from the rated content weight, not the gallon number.
Pad and structure
A loaded vertical tank concentrates that full rated load onto a 64 x 64-inch square, so the pad underneath it does real work. Size and reinforce it for the maximum rated weight before the tank is set, then keep it level and supported across the entire base. Our concrete pad sizing guide walks through the ACI 360R-10 framework and the ACI 318 boundary for above-ground polyethylene tanks. If this 550 anchors a rural fire-water reserve or an industrial water-reuse train, the fire-water reservoir design guide and the water-reuse tank topology guide cover sizing the storage stage correctly.
The mistake to avoid
Don't treat the 1.9 SG rating as a license to fill this tank with any heavy liquid. The rating describes the maximum contents density the shell can carry; it is not a chemical-service approval. This page lists no fittings and no chemical-compatibility data for this tank, so before plumbing it for anything other than water, confirm the fitting and outlet layout against Snyder's product documentation and verify the chemistry separately. The cleanest way to get that right is to call 866-418-1777 with your intended outlet location and size so the correct bulkhead fitting and gasket are specified at order rather than guessed after delivery. For density-heavy service, the Snyder Captor freeboard sizing guide shows how thermal expansion and density eat into usable volume.
This Snyder vertical tank ships LTL freight from the nearest Snyder plant, Chowchilla, CA or Lincoln, NE, with the exact cost quoted live to your ZIP. Western ZIPs generally ship from Chowchilla and Plains, Midwest, and Eastern ZIPs from Lincoln, so freight on a 550 gallon vertical tank like this lands materially lower across much of the country than it would from a single-origin seller. Run your ZIP through our Freight Cost Estimator for the live number; listed price is before freight. To confirm the right 550-gallon vertical tank for your site or lock in a freight quote, call 866-418-1777.
