The Snyder Industries 550 Gallon Black Heavy Duty Vertical Storage Tank (SKU 1800400C34) is a 550-gallon vertical storage tank molded from heavy-duty polyethylene in black and rated to a 1.9 specific gravity. That 1.9 rating is the headline spec: where a standard 550-gallon water tank tops out around a lighter specific-gravity rating, this Snyder vertical is built and rated to carry the denser liquids that would over-stress a lighter-walled tank. It stands 75 inches tall on a 48 x 48 inch footprint, making it a tall, compact storage tank that fits a small concrete pad while still holding the full 550 gallons.
Will it work for your liquid and your space?
Footprint: 48 x 48 in. Overall height: 75 in. Filled with water, this tank carries about 4,587 pounds; because it is rated to a 1.9 specific gravity, the maximum rated contents weight climbs to roughly 8,715 pounds with a dense liquid filling the full volume. Plan your pad, anchoring, and forklift or crane access around the heavier of those two numbers, not the water figure. The black polyethylene wall blocks light, which discourages algae growth in stored water and protects light-sensitive contents. If you are not certain 550 gallons is right for your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a footprint. If you plan to store a dense liquid, review the Snyder freeboard sizing guide first, because thermal expansion and density change the volume you can actually use.
Mounting, pad, and the mistake to avoid
A tall vertical tank on a 48-inch base is top-heavy when full, so a flat, fully supporting pad is not optional. Review the technical drawing on this page for the exact dimensions, fitting locations, and overall height before you size the slab and frame any access. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that foundation right. The mistake to avoid: do not assume the water weight is your design load. This tank is rated for a 1.9 specific gravity, and if you fill it with a denser-than-water liquid you must design the pad and supports for the full 8,715-pound rated contents weight, or you risk uneven settling and stress on the tank base.
Putting this vertical tank to work
This is a workhorse black vertical storage tank for water and heavy-liquid storage where headroom is tight and floor space is at a premium. For larger, multi-source storage programs, the industrial water reuse tank topology guide covers grey-water, rainwater, and condensate aggregation, and rural fire-protection planners can reference our fire-water reservoir tank design guide for NFPA 22 sizing.
