The Snyder Industries 1100 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a crosslinked linear polyethylene vertical storage tank rated to 1.9 specific gravity, giving you real headroom for dense liquids without pushing the wall to its limit. It stands 55 inches tall on an 86 by 86 inch footprint and holds 1,100 gallons in a Natural White finish. For anyone comparing a heavy-duty vertical tank, this XLPE model answers three questions up front: what it holds and how it plumbs, how it ships, and the one sizing detail that trips people up.
What this tank handles
The crosslinked (XLPE) wall is the heavy-duty version of a vertical storage tank, built to ASTM standards and rated to 1.9 specific gravity. A full load of water weighs 9,174 pounds; loaded to the tank's maximum rated contents the assembly reaches 17,431 pounds, so your pad and any tie-downs have to carry that number, not the water figure. Plumbing is already provisioned: the technical drawing on this page shows a bolted flange, two flat fitting pads including a 9-inch by 9-inch pad, an 18-inch polyethylene threaded and vented top fitting, and a manway with 15-inch access for interior reach during cleaning and inspection. The bolted flange and manway seal on gaskets that must be matched to the liquid you are storing, and the flat pads are meant to be self-drilled so you can add your own bulkhead fittings on the orientation you need. Confirm the fitting locations against the drawing before you set the tank, since how it sits on the pad determines where your inlet and outlet land. For rural or remote water storage, the fire-water reservoir design guide covers where an 1,100-gallon tank fits in an NFPA 22 private fire-protection stack.
Sizing the pad and the load
This is a squat, wide vertical at 55 inches tall on an 86 by 86 inch base, and that shape puts more edge load on the slab than a tall, narrow tank does. Pour a full-bearing 86 by 86 inch pad under the entire base and size it to the loaded weight, not the empty shell. Because XLPE is rated to 1.9 specific gravity, the tank can legally hold liquid far heavier than water, and the 17,431-pound max rated contents weight reflects that ceiling. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before pouring, and if the tank sits above grade, the concrete pad sizing framework walks through the ACI approach for a load this heavy.
XLPE versus HDPE, and the mistake to avoid
The most common misstep on a heavy-duty vertical tank is treating XLPE and HDPE as interchangeable. Crosslinked polyethylene earns its 1.9 specific gravity rating and its heavier wall through the crosslinking process, which is exactly why this model is spec'd for demanding storage. The Snyder XLPE vs HDPE guide explains when that crosslinking actually matters for your duty. The second mistake is misreading the vent: the 18-inch polyethylene threaded and vented top fitting is the tank's built-in vent, not a separate vent line to spec elsewhere, and your fill and draw rates have to stay within what it can move or you risk pulling a vacuum on drawdown. If your duty is aggressive or regulated and you need secondary containment, note that this is a single-wall tank; the Snyder Captor double-wall freeboard guide covers the containment upgrade path.
