The Snyder Industries 250 Gallon Heavy Duty Vertical Storage Tank is a 64-inch-tall vertical storage tank on a compact 36 x 36-inch square footprint, molded from natural white polyethylene and rated to a 1.9 specific gravity. That 1.9 SG rating is the headline here. It means the tank can hold contents up to 1.9 times the density of water — roughly 90% more dead weight than a full water load — without flexing past its design limit. This is the heavier-wall build, not a relabeled water tank, so you get a real safety margin on straight water and the engineered load capacity if you ever store something denser.
Will it work for your site?
At 250 gallons, a full load of water weighs roughly 2,085 pounds, while the tank is rated to carry up to 3,962 pounds of contents at its full 1.9 specific gravity. Plan your pad and anchoring around the weight you will actually put in it, not just the gallon number. The 36 x 36-inch footprint keeps this vertical tank tight against a wall or inside a containment area, and overall height is 64 inches. If you are running a gravity-fed line, confirm the outlet location and elevation on the technical drawing on this page to calculate the real available head, since the rated height is the overall tank dimension, not the pressure head at an outlet. If you are weighing this 250 gallon storage tank against a larger or smaller size, the Tank Sizing Calculator and our Tank Sizing Guide walk through matching capacity, footprint, and refill cadence to your demand.
Fittings and chemical compatibility
Fitting and gasket configuration is not pre-specified for this tank. Verify the outlet and bulkhead size, then select your gasket material for the fluid you are storing, all against the technical drawing on this page, before ordering valves, hose, or bulkhead fittings. Because this is the 1.9 SG version, it is the right pick whenever you might store something denser than water — fertilizers, brines, and similar contents — rather than a standard water-only tank. If you are choosing between this and a lighter water tank, the heavier-wall 1.9 SG build is what lets you carry that extra density safely. Match the fittings to the tank, not the other way around.
Mounting and support
A loaded vertical tank wants a flat, fully supported, level base — the full footprint carries the weight, not the edges. At max rated load, the 36 x 36-inch base carries about 440 pounds per square foot, so size the pad and subgrade for that figure, not the 2,085 pound water number. For an above-ground concrete pad, our guide to concrete pad sizing for above-ground polyethylene tanks covers the ACI framework that keeps a multi-thousand-pound load stable over time. If this tank is going into a private fire-protection or rural water-reserve role, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For greywater, rainwater, or HVAC condensate aggregation, see our industrial water reuse tank topology guide.
The mistake to avoid
Don't size your pad, fittings, and anchoring around 2,085 pounds when this tank can legitimately carry 3,962. The 1.9 SG rating exists so the tank can hold heavier-than-water contents, and if you load it near that limit, your foundation and fittings have to be specified for the real number. Check the outlet size and placement on the technical drawing before ordering valves or hose, so the plumbing matches the tank.
