The Snyder Industries 550 Gallon Heavy Duty Vertical Storage Tank is a closed-top polyethylene vertical built for bulk water and high-density liquid storage. It holds 550 gallons in a 64-inch footprint and carries a 1.9 specific gravity rating, which is the headline number on this tank. At that density, contents weigh up to 8,715 pounds versus 4,587 pounds for a full water column, so this is a heavy-duty wall engineered for liquids substantially denser than water. That rating is exactly what you are buying.
Will it work for your site
This is a vertical storage tank in Natural White polyethylene, listed at 64 inches in width and 46 inches in height, sitting on a 64.0 x 64.0 inch square footprint. Confirm the height and diameter against the technical drawing on this page before you finalize a layout, then plan your pad and clearances around that footprint. Filled with water, the tank and its contents weigh about 4,587 pounds, so the slab underneath has to be flat, level, and continuously supported across the full base. At its maximum rated content density of 1.9 SG, total contents weight climbs to roughly 8,715 pounds, so if you are storing anything heavier than water, size the foundation to the 8,715 lb figure, not the water figure. To match gallons and density to your application, run the Tank Sizing Calculator and review the Tank Sizing Guide before you commit.
Foundation and pad sizing
A vertical of this weight class lives or dies on its base. An uneven pad is the most common cause of premature stress on a poly tank, and a dense liquid load only raises the stakes. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab carries the full base evenly. If this 550 is going into a rural fire-water reservoir or remote site, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, see the industrial water reuse tank topology guide.
The mistake to avoid
Do not assume every 550-gallon vertical is interchangeable. This Snyder is the heavy-duty 1.9 SG build. If your liquid is denser than water, confirm it falls within the 1.9 SG ceiling before ordering, and never set a tank rated for a lighter contents density in its place. The second mistake is fittings: this tank's outlet and fitting configuration should be confirmed against the technical drawing on this page before you plumb anything, so your bulkhead and valve sizes match what the tank actually ships with.
