The Snyder Industries 290 Gallon Open Top Containment Tank (VOT) is a cylindrical open-top vessel molded in high density linear polyethylene and rated to a 1.9 specific gravity — the SG band that separates a general-purpose water tank from one built for dense contents heavier than water. It stands 47 inches tall on a 42 x 42 inch footprint, holds 290 gallons, and is white, with contents checked and worked directly at the open top. Its product name flags it for sulfuric acid storage, so if your job is secondary containment, dense-liquid storage, or open-top batch work, this is the size where the wall thickness and the SG rating are doing real work.
Will it hold what you are putting in it?
The number that matters is the 1.9 specific gravity rating. Full of plain water this tank carries roughly 2,419 pounds; loaded to its maximum rated contents weight it is engineered to carry up to 4,595 pounds. Across the 290-gallon volume, that ceiling works out to about 15.8 pounds per gallon — the full 1.9 SG the tank is rated for. That headroom above the water figure is exactly what the 1.9 band buys you, and it is why this tank suits contents heavier than water rather than a standard 1.0–1.5 SG water tank. On the 42 x 42 inch footprint, plan your pad and any restraint for the loaded weight, not the empty shell. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 290-gallon working volume against your fill-and-draw cycle before you order.
Open-top format — what to plan for
This is an open-top cylindrical tank, so the top is accessible for manual filling, mixing, or dropping in a pump or agitator, and it is a natural fit as a containment or catch vessel. Because it is open, it is not a sealed pressure or transport tank — plan a cover or lid separately if your contents need protection from rain, debris, or evaporation, and keep the working level below the rim for the freeboard your process needs. This open-top VOT ships without published fittings in our data, so confirm any outlet or drain configuration by calling 866-418-1777 before you order. For above-ground siting, size the concrete pad to the loaded footprint using our concrete pad sizing framework.
The mistake to avoid
The trap on a dense-contents tank is treating the specific-gravity rating as optional. The 1.9 SG rating is what qualifies this tank for heavier-than-water liquids, and no contents load should exceed the 4,595-pound maximum rated weight. For acid service in particular, the SG rating alone does not cover chemical resistance: always confirm your specific contents — including sulfuric acid concentration and service temperature — against the manufacturer's published chemical-resistance chart before filling, rather than assuming the rating settles it.
