The Snyder Industries 1100 Gallon Heavy Duty Vertical Storage Tank is molded from crosslinked linear polyethylene (XLPE) and built to ASTM standards for above-ground poly storage. It carries a 1.9 specific gravity rating, meaning the wall is engineered to hold contents up to 1.9 times the density of water. On this black vertical tank that translates to real capability: 1,100 gallons of clear water weighs about 9,174 lb, and the tank is rated to carry up to 17,431 lb of contents at full 1.9 SG. The black resin also blocks light, which slows algae growth in stored water compared to translucent tanks.
Does it fit and will it work for you?
This vertical storage tank stands 55 inches tall on a full-diameter footprint of 86.0 x 86.0 inches — a squat, wide profile, so plan the pad for the width and check fill-line clearance at just under five feet of height. The drawing shows five port locations: a flange, an 18-inch PE threaded/vented fitting, a manway with 15-inch access for interior inspection and cleaning, a 15" x 15" fitting, and a flat fitting pad. The bolted flange and bolt-down manway both seal on gasketed connections, so confirm the gasket and bolt-kit are included and verify exact port sizes and placements against the technical drawing on this page before you plumb. Use our Tank Sizing Calculator and Tank Sizing Guide to match the tank to your draw rate and refill cycle. Sizing a fire-water reservoir?

XLPE vs HDPE — the mistake to avoid
This is crosslinked polyethylene, not standard HDPE. Crosslinking is what earns the higher SG rating and the better resistance to stress cracking that makes it heavy duty. Do not treat XLPE and HDPE as interchangeable when you spec a replacement or plan future duty — the Snyder XLPE vs HDPE guide explains when the difference matters. The 1.9 SG rating here is the heaviest-duty rating this tank offers, so there is no step-up model to chase for dense or heavy contents — this one already carries up to 17,431 lb. That said, over 17,000 lb loaded means the pad has to carry the load flat and level; review the concrete pad sizing framework before you pour.
