The Snyder Industries 1500 Gallon ASTM HDPE Heavy Duty Vertical Storage Tank is a 1,500-gallon vertical storage tank molded from high density linear polyethylene in a natural white shell. It stands 77 inches tall on an 89 x 89-inch footprint and carries a 1.9 specific gravity rating, which is what earns it the "heavy duty" designation over a standard 1.0 or 1.5 SG water tank. In water service the pad and anchoring see 12,510 pounds of contents; the 23,769-pound figure is the structural ceiling at 1.9 SG, not a water-service fill load. If you are comparing sizes, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a footprint.
Does it fit your job?
This is a workhorse vertical HDPE storage tank for bulk water, rainwater capture, and general non-pressurized liquid holding. The 89 x 89-inch footprint and 77-inch height keep it low and stable relative to taller 1500-gallon profiles, a practical advantage under a low roofline or on a bermed pad. Plan an 89 x 89-inch pad with clearance around the 15-inch manway so a technician has room for entry during cleaning and inspection. The 1.9 SG rating means this unit already covers denser-than-water duty, so if you are weighing a lighter 1.5 SG tank for marginal density, stepping up to this shell is the safer structural call.
Fittings and access
Per the technical drawing on this page, the tank is configured with a flange fitting, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access. Confirm the fitting locations, elevations, gasket, and bolt-torque spec against the drawing before you plumb your inlet, outlet, and vent runs or seal the flange and manway. This is an HDPE water-service shell; for aggressive chemistry, crosslinked XLPE resin may be required, so review our guide on Snyder XLPE vs HDPE and when crosslinking matters before pairing this tank with anything more demanding than water.
The mistake to avoid
The common error on a heavy-duty tank like this is treating the 1.9 SG rating as an invitation to skip freeboard and ullage math. That rating is a structural ceiling, not a fill line. Size your working volume with real freeboard for thermal expansion using ASTM D1998 logic, as covered in our wall-thickness and vapor-headspace failure guide. For fire-reserve or cold-climate service, our fire-water reservoir and freeze-protection guide walks through the discipline. Match your fittings to the drawing rather than guessing thread sizes.
This vertical storage tank ships LTL freight, quoted live to your ZIP from the nearest Snyder plant in Lincoln, NE or Chowchilla, CA. Because it weighs several tons filled, it ships empty on a pallet and is handled as motor freight, not parcel. Get a real number with our Freight Cost Estimator, or call 866-418-1777 to lock in your fittings, footprint, and delivery. Listed price is before freight, which is quoted separately to your ZIP.
