The Snyder Industries 550 Gallon Heavy Duty Vertical Storage Tank is a 550-gallon polyethylene vertical tank built for above-ground bulk water storage where the contents run heavier than plain water. It stands 75 inches tall on a 48 x 48 inch square footprint, molded in natural white polyethylene so you can eye the liquid level through the wall. The heavy-duty wall carries a 1.9 specific gravity rating, which means the resin and wall thickness are engineered for liquids up to 1.9 times the density of water, not just water at 1.0.
Will this vertical storage tank work for your job
Sized as a vertical storage tank at 550 gallons, this is a common choice for rural and remote water reserves, water reuse trains, and general industrial bulk water holding. Plan your slab and rigging around the loaded weight, not the empty shell. The water alone weighs about 4,587 pounds, and at the full 1.9 specific gravity rating the maximum rated contents weight climbs to roughly 8,715 pounds, so a pad sized for water is not automatically sized for the heaviest liquid this tank is rated to hold. One more delivery note: at 75 inches tall, this tank needs door, gate, and overhead clearance for upright placement, and your fill point has to be reachable at that height, so map the path in before the truck arrives. For help matching gallons to your draw and refill cycle, use our Tank Sizing Calculator and the Tank Sizing Guide.
The 48 x 48 footprint and your pad
This vertical tank concentrates its full load onto a 48 x 48 inch square footprint, so the foundation matters more than the diameter suggests. A 550-gallon column of dense liquid puts real pressure per square inch on whatever it sits on. Pour or verify a level, properly sized pad before delivery. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting this right, and if you are designing a rural fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
The mistake to avoid
The number that trips buyers up on a heavy-duty tank is the 1.9 specific gravity rating. It is a ceiling, not a license to skip the math. The rating tells you the tank wall can carry liquid up to 1.9 SG, but your pad, anchoring, and connections still have to be sized for the actual weight you intend to store. The spread is real: the same tank goes from about 4,587 pounds full of water to roughly 8,715 pounds at its maximum rated contents weight, and the foundation has to be sized to whichever your liquid lands on. If your liquid needs secondary containment, see our Snyder Captor double-wall sizing guide, and if you are pairing this with a water reuse system, our industrial water reuse tank topology guide covers quality-banded storage trains.
