The Snyder Industries 290 Gallon Open Top Containment Tank (VOT) is a 47-inch-tall open-top cylinder measuring 42 inches in diameter (a 42 x 42-inch footprint envelope), molded in white High Density Linear Polyethylene and rated to a 1.9 specific gravity. That combination makes it a workhorse for open-top water storage, batch mixing, and use as a containment or catch basin under a smaller process vessel or pump skid. The open top gives you full access to the interior for cleaning, hand-adding product, or dropping in a mixer or heater, and the round wall keeps the footprint compact where floor space is tight.
Will it work for your application?
Rated capacity is 290 gallons in a 47 in tall by 42 in diameter envelope. Water fills to roughly 2,419 pounds, and the tank's 1.9 specific gravity rating supports a maximum rated contents weight of about 4,595 pounds, so it carries heavier-than-water fluids and slurries well within its structural limit. That 1.9 SG works out to about 15.8 pounds per gallon of allowable fluid density, so you can check your own product against the wall rating without a calculator. The high-SG headroom is the reason to reach for this Snyder VOT over a plain open water drum: you get real margin for dense contents rather than a wall built only for fresh water. One spec to plan around up front: this VOT ships as a bare open-top vessel with no molded bulkhead or outlet fittings, so any drain, outlet, or overflow is a field add. If you are matching capacity to a duty cycle, a peak-demand reserve, or a rural fire-water reserve, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide, and see our fire-water reservoir tank design guide for reserve-sizing discipline before you commit to a size.
The mistake to avoid
Do not confuse an open top containment tank with a closed, vented storage tank. With no lid and no top fittings, this is a catch basin and batch vessel, not a sealed tank for pressurized or fully enclosed service, and you should keep it out of weather and debris where an open top invites contamination. Respect the 1.9 SG ceiling too: it is generous, but it is a rating, not a license to exceed the 4,595-pound contents limit. When this tank sits under process equipment as secondary containment, size the basin to the volume you actually need to catch and set it on a proper pad. Our guide on concrete pad sizing for above-ground polyethylene tanks and, for transfer-station layouts, our loadout pad engineering walkthrough cover the civil work that keeps an open-top install clean and stable.
Freight: how it ships
This open top containment tank ships LTL freight from the Snyder plant nearest your project, which for this model is Merced, CA. Because open-top tanks travel as bulky low-density freight, the rate is driven by destination and accessorial needs, so it is quoted live to your ZIP rather than baked into the list price. Pull a real number for your delivery ZIP with our Freight Cost Estimator, or call 866-418-1777 and we will book the LTL carrier from Merced, CA to your ZIP.
