The Snyder Industries 5600 Gallon XLPE Black Heavy Duty Vertical Storage Tank is a full-size bulk vertical storage tank molded in crosslinked linear polyethylene (XLPE), rated to a 1.9 specific gravity. That heavy 1.9 SG rating is the number to read first: it means this tank is built to hold contents far denser than water, so for plain water storage you have substantial structural headroom. Standing 102 inches (8.5 ft) tall on a 142 x 142 inch footprint (roughly 11.8 ft across), this is a large-diameter vertical tank for anyone searching for a serious black XLPE storage tank, not a utility drum.
Will it work for your site?
Capacity is 5,600 gallons. Full of water, contents weigh 46,704 lb; at the full 1.9 SG rating the tank is engineered for up to 88,738 lb of contents. Those weights drive everything else, so plan the pad and access before the tank ships. A tank this heavy needs a level, engineered, load-bearing base sized for the full water weight and the 11.8-foot diameter footprint; our concrete pad sizing guide walks the ACI framework for above-ground poly tanks. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 5,600 gallons is the right volume before you commit.
Why the 1.9 SG XLPE tier matters
Crosslinked polyethylene is the tougher, more impact- and stress-crack-resistant cousin of standard HDPE, which is why Snyder molds heavy-duty storage tanks in it. The 1.9 specific gravity rating is the heavy-duty tier: the same tank that stores water today is built to handle denser fluids up to 1.9 SG later, so future duty does not mean re-buying. If you are weighing crosslinked against standard poly, our guide on Snyder XLPE vs HDPE explains where crosslinking earns its keep, and the Snyder Captor freeboard guide covers thermal expansion and the real usable volume you can plan around at a given density.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access, plus prepared mounting flats at 171.5 degrees and 261.5 degrees. The 18-inch vented threaded fitting matters on a tank this size: a large vertical storage tank needs adequate venting so it can fill and drain without pulling a vacuum or pressurizing the dome. The two clock-position flats are the prepared locations for adding side fittings or instrumentation, so if you are planning a level gauge or an extra outlet, reference those positions against the drawing before ordering hardware. Match each seal to your service: the flange, the 18-inch threaded/vented fitting, and the 15-inch-access manway all need a gasket compatible with the stored fluid and its temperature. Confirm your inlet, outlet, and vent plan against the drawing before you order any bulkhead or plumbing hardware.
The mistake to avoid
Do not underbuild the foundation. The single most common error on a tank this size is setting a 5,600-gallon vertical tank on a base that is not dead level or not rated for the full 46,704 lb water load; uneven or undersized support concentrates stress on the tank wall and shortens its life no matter how good the XLPE is. Get the pad right first, then the tank does its job. For large-volume water reserves such as rural fire-protection storage, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
