The Snyder Industries 5500 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank (SKU 7020000N42) is a full-size vertical storage tank molded in crosslinked linear polyethylene (XLPE) and rated to a 1.9 specific gravity. That density rating is the headline number here. At a 90 x 90 inch footprint and 221 inches (18.4 feet) tall, this Natural White tank holds 5,500 gallons and is built to carry contents nearly twice the density of water. Water sits at roughly 1.0 SG, so a water buyer gets genuine wall headroom with zero derating worry today and a clear path if the future contents ever get heavier.
Will it work for your site
Plan the pad and the plumbing around the real weights, not just the gallons. Filled with water, this vertical storage tank and its contents come in around 45,870 lb; at its maximum rated 1.9-SG contents it carries about 87,153 lb. That is the load your concrete pad and soil have to accept, so size the foundation accordingly. A tall, narrow profile like this 221 x 90 x 90 XLPE tank needs a level, engineered pad and warrants anchoring and wind consideration on exposed sites. The technical drawing on this page shows the fitting layout: a flange, an 18-inch PE threaded/vented fitting, a manway with 15-inch access, a fitting flat at 272.5 degrees, and a S.U.M.O. fitting. That 15-inch manway matters on a tank you cannot otherwise reach into, giving you interior access for inspection and cleaning over the tank's life.
Confirm the fittings before you set it
Match your vent and inlet plan to the vented 18-inch PE fitting specifically, and verify the flange and S.U.M.O. positions against the fitting flat at 272.5 degrees on the drawing before the tank is placed. Confirm gasket and bulkhead thread sizes at the flange and the 18-inch fitting against your existing plumbing first, because a 90 x 90 footprint at over 18 feet tall is not something you reposition once it is plumbed. Our Tank Sizing Calculator and Tank Sizing Guide help match capacity to your draw-down and refill cycles, and the concrete pad sizing framework walks the ACI 360R-10 and ACI 318 boundaries. For rural fire-water or reservoir duty, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
Why XLPE
The most common mistake on a heavy-duty vertical is treating XLPE and HDPE as interchangeable. Crosslinked polyethylene cures into a more impact- and stress-crack-resistant wall, which is why this tank earns its 1.9-SG rating instead of a lighter water-only spec. If you are weighing the two, read Snyder XLPE vs HDPE: when crosslinking matters before you commit.
