The Snyder Industries 3000 Gallon Vertical Double Wall Liquid Storage Tank is a containment-grade vertical storage tank built for liquids that demand secondary containment. It holds 3,000 nominal gallons in a 102-inch diameter footprint, stands 142 inches tall, and is molded in white from high density linear polyethylene with a 1.9 specific gravity rating. The double wall design seats the inner storage tank inside an outer containment tank, so a primary leak is caught rather than released to the ground. For placement, plan for a 102 x 102 in (8.5 x 8.5 ft) pad footprint and 142 in (about 11.8 ft) of vertical clearance for door, gate, and ceiling height before delivery.
Will this tank work for your liquid?
Match the contents to the tank's 1.9 specific gravity rating. Specific gravity is the density of your liquid compared to water, where water is 1.0, so a 1.9 rating means this Snyder vertical tank is engineered to hold liquids up to nearly twice the weight of water at full volume. That is why it carries a maximum rated contents weight of 47,538 pounds, while plain water at full volume weighs 25,020 pounds. Confirm your liquid's actual specific gravity is at or below 1.9; if your fluid exceeds 1.9, this tank is not rated for it. As an HDLPE tank, it is suited to water and general liquid storage, and for any aggressive chemical you should confirm chemical compatibility against the 1.9 SG rating and your gasket material by calling 866-418-1777. If you are unsure how the capacity maps to your draw rate or refill schedule, the Tank Sizing Calculator and Tank Sizing Guide walk through the math for a vertical storage tank like this one.
Double wall freeboard and usable volume
A double wall tank does not always give you every gallon of nominal capacity as usable working volume. The 3,000 gallons is a nominal figure; usable working volume is lower once freeboard - the empty space left at the top - is accounted for, and the rules tie back to ASTM D1998. Size to working volume, not the nameplate. Before you commit to a fill level, read our guide on Snyder Captor double-wall freeboard sizing per ASTM D1998, which covers thermal expansion, density, and the real volume you can actually use. For dimensional details on this size class, see the technical drawing on this page and our buyer's guides for comparable 3000 gallon vertical liquid storage tanks.
The mistake to avoid
The common error on a double wall vertical tank this large is planning the pad for the water weight instead of the rated contents weight. At full plain-water fill the contents are 25,020 pounds, but the tank is rated to 47,538 pounds of contents at its 1.9 specific gravity. Size your foundation to the maximum rated load and the actual density of your liquid, not to water, or you risk an undersized pad under a fully loaded containment tank. One more confirmation step before you order: fitting, outlet, vent, and gasket configuration is not listed for this SKU, so call 866-418-1777 to confirm bulkhead size, gasket material, and outlet placement match your plumbing.
