The Snyder Industries 550 Gallon Black Heavy Duty Vertical Storage Tank is a 550-gallon polyethylene vertical storage tank built for bulk water and dense-liquid duty. What separates it from a standard 550 is its load ceiling: a 1.9 specific gravity rating and a maximum rated contents weight of 8,715 pounds, meaning it is engineered to hold liquids up to 1.9 times the weight of water - well past the demands of plain water storage. It stands 46 inches tall on a 64-by-64-inch footprint, so it slides under low ceilings and tight roof lines where a taller 550 would not fit, while the wide square footprint keeps it stable when full. The black resin blocks light to discourage algae growth in stored water.
Will it work for your site?
Plan your slab and stand around the 64.0 x 64.0 inch footprint and the 46-inch height. Filled with water, the tank and contents weigh about 4,587 pounds, so the pad and any supporting structure must carry that load with margin. The 1.9 SG rating gives this vertical tank a much higher ceiling - the 8,715-pound maximum rated contents weight is what makes it a true heavy-duty unit rather than a light water-only shell. If you are deciding between this and a taller, narrower tank, the squat 46-inch profile is the deciding factor for height-restricted bays, basements, and trailer-mounted setups. Our Tank Sizing Calculator and Tank Sizing Guide walk you through matching capacity, footprint, and load to your application.
How it ships
This black vertical storage tank ships LTL freight, quoted live to your ZIP code. It moves from the nearest Snyder plant - Marked Tree, Arkansas or Philippi, West Virginia - so buyers across the central and eastern states generally see shorter lanes and lower freight than ordering the same tank from a coast. Because a 64-inch-wide vertical tank is a dimensional freight item, the carrier rate depends on your destination and delivery conditions. Run your ZIP through the Freight Cost Estimator for a live quote, or call 866-418-1777 and we will rate the closest lane for you.
The mistake to avoid
The most common error on a tank like this is treating the 1.9 specific gravity rating as headroom you never need to think about. The rating exists for a reason: if you intend to store a liquid heavier than water, confirm the contents fall within that 8,715-pound maximum rated weight before you fill, and verify the fittings and outlet plumbing you add are rated for the same service. For straight water storage you have generous reserve; for anything denser, do the weight math first - our Snyder freeboard and density sizing guide shows how thermal expansion and contents density eat into usable volume. It is also worth confirming your foundation is dead level - a vertical storage tank this wide concentrates real load at the base, and an uneven pad puts uneven stress on the wall. See the technical drawing on this page for outlet and dimensional detail.
