The Snyder Industries 3000 Gallon Heavy Duty Vertical Storage Tank is a crosslinked polyethylene (XLPE) vertical tank built to ASTM D1998, standing 111 inches tall on a 96 x 96 inch square footprint. It holds 3,000 gallons of natural white XLPE and carries a 1.9 specific gravity rating, which is what separates this tank from a standard water-only vertical: the heavier crosslinked wall is engineered to hold contents far denser than water, and 1.9 is Snyder's ceiling for this heavy-duty XLPE class, not a step below a denser sibling.
Will it work for your site?
Full of water this tank weighs roughly 25,020 pounds; at its maximum 1.9 SG rating the contents alone can reach about 47,538 pounds. Spread across the 64-square-foot base, that loaded weight puts on the order of 740 pounds per square foot into your slab before any pad design — the single number that tells you whether existing soil or concrete is even a candidate. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and use the concrete pad sizing framework (ACI 360R-10) for the load path a 96 x 96 inch base drives into the slab. The tank is fitted with a flange outlet, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for interior entry and cleaning. The 18-inch fitting doubles as the primary vent, so do not cap it — a sealed vent pulls a vacuum on drawdown. Confirm the flange diameter, fitting locations, and outlet elevation against the technical drawing on this page before you plumb.
XLPE versus HDPE, and usable volume
The crosslinked wall is the reason to pick this over a linear HDPE vertical of the same capacity; crosslinking builds stress-crack resistance into the resin, which is why the 1.9 SG rating exists at all. Our guide on Snyder XLPE vs HDPE covers when that difference earns its place, the freeboard sizing walkthrough per ASTM D1998 explains how much of the nominal 3,000 gallons you can actually plan on using, and the fire-water reservoir design guide ties this vertical storage tank into a private fire stack and cold-climate freeze protection.
The mistake to avoid
Do not read the 1.9 SG rating as a license to store anything. It confirms the tank can structurally carry a dense contents column; it does not by itself confirm chemical compatibility. On a heavier service the real failure point is usually the gasket, not the polyethylene body — match your intended contents to a Snyder chemical-resistance reference and verify the elastomer (EPDM versus Viton) sealing the flange and 18-inch fittings is rated for that fluid before you fill. Size the pad for the loaded weight, and set the outlet elevation before the tank is on the pad, not after.
