The Snyder Industries 330 Gallon Vertical Storage Tank is a heavy-duty black crosslinked polyethylene (XLPE) tank built for demanding above-ground storage where a standard linear tank falls short. Molded to ASTM standards with a 1.9 specific gravity rating, it stands 58 inches tall on a 44 x 44 inch footprint, giving you real vertical storage capacity without a sprawling floor plan. Here is what you need to know to buy it right: whether it fits your job, how it ships, and the one detail people get wrong.
Does it work for your job?
This is a vertical storage tank with a 330-gallon capacity in black XLPE. The crosslinked resin gives it a tougher, more impact- and stress-crack-resistant wall than standard HDPE, which is why the tank carries a 1.9 specific gravity rating rather than the usual 1.0 to 1.5 you see on lighter-duty water tanks. In plain terms, that rating means the tank is engineered to hold contents heavier than water. If you want to understand why crosslinking earns that headroom, our guide on Snyder XLPE vs HDPE walks through when it matters. The black exterior blocks light, which discourages algae growth in stored water compared to a translucent or lighter tank. Fitting configuration is not specified in our data, so call 866-418-1777 to confirm outlet size, lid, and gasket before you order rather than assuming the tank arrives plumbed.
Weight, footprint, and pad
Size this tank for its loaded weight, not its empty shell. Full of water, the 330-gallon capacity puts roughly 2,752 pounds on your pad. At the tank's full 1.9 specific gravity rating, maximum rated contents weigh about 5,229 pounds, which works out to roughly 2.7 psi spread across the 44 x 44 inch base. That is a serious sustained point load, so the supporting surface has to be flat, level, and continuous under the entire footprint. Our concrete pad sizing guide covers the ACI framework for getting that base right, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 330 gallons is the volume your application actually needs.
The mistake to avoid
The common error is treating this like any other black vertical water tank and buying the wrong specific gravity spec for the job. This tank's 1.9 rating is a genuine strength that lets it store denser contents safely, but a lighter standard-duty tank at the same gallon size cannot do that. If your stored liquid is heavier than water, this XLPE build is the right call; if you only ever store water, know that you are paying for headroom you may not need.
