The Snyder Industries 4400 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a natural white, crosslinked linear polyethylene (XLPE) vessel built for demanding bulk storage where a standard HDPE wall would be pushed past its limits. It holds 4,400 gallons in a 90-inch by 90-inch footprint and stands 182 inches tall. Before you commit, check that raw envelope against your site: 90" x 90" x 182" is over 15 feet high, and door clearance, roofline, and pad dimensions are the number-one reason a vertical this size gets refused at delivery.
Will it work for your site?
Full of water this tank weighs roughly 36,696 lb, and at its 1.9 specific gravity rating it is engineered to carry up to about 69,722 lb of contents. In plain terms, a 1.9 SG rating means the wall is built for contents up to about 1.9 times the density of water, so for plain water service you are buying real headroom on wall strength. Those weights drive the foundation: a tank this size wants a properly sized, level, fully supported concrete pad, not compacted gravel alone. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 4,400 gallons is the right working volume for your draw rate and reserve.
Fittings and access
Per the technical drawing on this page, this vertical storage tank is configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, a 2-3 inch S.U.M.O. fitting, a 12-inch by 14-inch fitting, and a flat fitting land for field-added connections. The 12"x14" fitting is the largest penetration on the tank, so verify it and the flange against your inlet, outlet, and overflow plan since those are the load-bearing connection points at this scale. The vent path is already provisioned at the 18-inch vented fitting, so size it for your fastest fill and draw. The 15-inch manway access matters for inspection and cleanout, so confirm it lines up with how you plan to service the tank, and match every count and size to the drawing before you plumb.
Why XLPE, and one thing not to skip
Crosslinked polyethylene gives you a tougher, more impact- and stress-crack-resistant wall than standard HDPE at this scale, which is why it is specified for heavy-duty vertical storage. The common mistake is treating XLPE as automatically chemical-rated for anything heavy or aggressive. Crosslinking helps with duty and density, not universal chemical resistance. Our guide on Snyder XLPE vs HDPE explains where crosslinking actually earns its keep before you assume this tank fits a given service.
