The Snyder Industries 90 Gallon Vertical Storage Tank is built from crosslinked linear polyethylene (XLPE) in black, standing 41 inches tall on a compact 34 x 34 inch square footprint. It carries a 1.9 specific gravity rating, which means the wall is engineered to hold contents substantially denser than water without deforming. For anyone weighing an XLPE vertical tank against a standard HDPE model, this Snyder unit answers the two questions that matter most: what it can safely hold, and how it lands at your site.
Will it work for your job?
At 90 gallons, a full load of water weighs 751 pounds, and the tank is rated to a maximum contents weight of 1,426 pounds thanks to that 1.9 specific gravity wall. Use those two numbers to plan your stand or pad: size the support for the heaviest liquid you intend to store, not just water. Keep in mind that rated capacity is not the same as usable volume once you account for freeboard and fill headroom; our freeboard sizing guide walks through the real volume you can actually work with. The 34-inch square footprint makes this vertical storage tank easy to place in tight utility rooms, on trailers, or against a wall where a wider round base would not fit. If you are sizing rural or remote reserve storage, the fire-water reservoir design guide covers NFPA 22 sizing discipline for a black XLPE vertical like this one.

Fittings and plumbing
The drawing shows a flange, a 14-inch polyethylene threaded and vented lid opening at the top, and a manway with an 11-inch clear access opening for filling, cleaning, hand entry, and inspection. Note what that fitting set does and does not include: there is no bottom or side outlet listed in the tank's fitting data. If you are planning gravity draw-down or a bulkhead drain, verify the outlet fittings on the technical drawing on this page before you order bungs or fittings, and confirm the drawing's fitting placement before you plumb the tank.
Why XLPE, and the mistake to avoid
Crosslinked polyethylene bonds the resin chains together during molding, giving the wall greater resistance to stress cracking and a higher structural safety margin than standard HDPE at the same thickness. That is why this tank carries a 1.9 specific gravity rating rather than the 1.0 to 1.5 typical of water-only tanks, so it already exceeds what a water-only tank offers for dense contents, no step-up needed. Our guide on Snyder XLPE vs HDPE covers when crosslinking earns its place. The common error with a heavy-duty vertical tank is under-building the support: 1,426 pounds concentrated on a 34 x 34 inch footprint will stress the base if the platform is flimsy or the pad is uneven. Set this tank on a smooth, level, fully supporting surface, size that base using the framework in Concrete Pad Sizing for Above-Ground Polyethylene Tanks, and confirm your intended contents are compatible with XLPE before committing to service.
