The Snyder Industries 5600 Gallon HDPE Vertical Liquid Storage Tank is built for bulk water and liquid storage where a large single-vessel footprint matters. It holds 5,600 gallons in a white polyethylene body measuring 142 inches in diameter by 102 inches tall, carries ASTM-certified construction, and is rated to a 1.9 specific gravity. That rating is the strongest reason to buy this particular tank: if you are storing water today but may move to a denser liquid - or simply want engineering margin - you are already covered, with no need to re-buy a heavier-walled vessel later. This is the vertical storage tank operators reach for on agricultural, fire-water, and industrial sites that need real volume without going to steel or concrete.
Will it work for your site?
Full of water, this tank weighs about 46,704 lb, and at its maximum rated 1.9 specific-gravity loading it carries up to 88,738 lb of contents. That weight has to land on a properly engineered pad - run the numbers against our concrete pad sizing guide (ACI 360R-10 framework) before you set it. The footprint is 142.0 x 142.0 inches, so confirm your pad and access clearances accommodate that diameter. Not sure 5,600 gallons is the right number for your draw and refill cycle? The Tank Sizing Calculator and Tank Sizing Guide walk you through it.
Fittings and access
This vertical tank comes configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for entry and inspection, plus blank moldable fitting flats at 171.5 and 261.5 degrees where you can field-install additional bulkhead outlets. Those flats are not pre-cut ports - plan on cutting and fitting them yourself if you need the extra outlets. The manway cover and bolt-on flange seal with gaskets, so confirm gasket material against your stored liquid before commissioning. See the technical drawing on this page for exact fitting locations and elevations before you plumb the tank. Wall thickness on HDPE verticals is engineered per ASTM D1998, and the thinnest, most failure-prone zone is the vapor-saturated headspace at the top - our breakdown of HDPE tank wall thickness and ASTM D1998 sizing logic is worth reading if this tank is going into long-term service.
The mistake to avoid
Don't size the pad or the rigging for water weight alone. This tank is rated to 1.9 specific gravity, and the difference between a full-water load (46,704 lb) and a full max-density load (88,738 lb) is nearly double. If you are storing anything denser than water - or planning a fire-water reserve where reliability is non-negotiable - design the foundation, anchoring, and lift plan for the rated load, not the convenient one. For fire-protection applications specifically, our fire-water reservoir design guide (NFPA 22) covers sizing and freeze-protection discipline.
