The Snyder Industries 5600 Gallon HDPE Vertical Liquid Storage Tank is a full-size bulk water tank molded in polyethylene, listed at a 1.9 specific gravity rating and built to ASTM standards for above-ground liquid storage. It stands 102 inches tall on a 142-inch-diameter base - so the 142 x 142-inch figure is the square pad footprint that the round 142-inch shell sits on, not a tank wider than it is tall. At 5,600 gallons in a single vessel, it is sized for rural fire-water reserves, agricultural water, municipal backup, and large-volume process water where you need real reservoir capacity from one vertical storage tank.
Will it work for your site?
This is a white, vertical HDPE storage tank rated to a 1.9 specific gravity. For water service at 1.0 SG, that means the tank carries fluids up to roughly 1.9 times the density of water, so you have substantial structural margin in normal water use: full of water the tank and contents weigh 46,704 pounds, while the shell is rated to a maximum contents weight of 88,738 pounds - about a 90% weight margin to that structural limit. The practical upside is that the same tank handles heavier brines or solutions if your service ever changes, with no need to re-buy. The technical drawing on this page details the fitting layout: a flange fitting, an 18-inch polyethylene threaded and vented inlet at the top, and a manway with a 15-inch access opening for inspection and cleaning. Two un-drilled flat-molded pads sit at 171.5 degrees and 261.5 degrees, letting you add bulkhead fittings where your discharge and overflow need them - confirm bulkhead size and gasket spec against your plumbing before install. If you are still confirming the size against your draw and refill rates, run the numbers in our Tank Sizing Calculator and Tank Sizing Guide.
Sizing the pad and the working draw
The 88,738-pound maximum contents rating is the number that matters when you size the pad and confirm your subgrade. For pad design on a tank this heavy, work through the ACI 360R-10 framework in our concrete pad sizing guide before you pour. Keep in mind the rated 5,600 gallons is gross shell volume - your usable working draw is less once you account for freeboard, so size your real capacity against the freeboard math in our freeboard sizing guide per ASTM D1998.
The mistake to avoid
On a tank this tall, premature failures tend to originate at the vapor-saturated headspace near the top wall, not at the liquid line where most operators look - the ASTM D1998 sizing logic behind that is worth understanding before you put the tank in service. Read our breakdown of HDPE tank wall thickness at the vapor-saturated headspace so your inspection routine checks the right zone. If this tank is going into private fire-protection service, size your reserve to NFPA 22 discipline and plan freeze protection for cold-climate sites using our fire-water reservoir design guide. The other common miss is under-specifying the inlet and outlet for your flow - confirm the 18-inch vented threaded inlet and the flange fitting match your fill and discharge plumbing before delivery.
Freight
This is a large vertical storage tank that ships LTL on a dedicated freight line item, shipped empty from the Snyder Industries plant in Philippi, West Virginia and quoted live to your ZIP code. Full of water it sits at roughly 46,700 pounds on the pad, but it travels as a single empty vessel, so freight is the tank only. Get an exact number with our Freight Cost Estimator, or call 866-418-1777 and we will quote the freight to your delivery address. Listed before freight - freight is quoted separately to your ZIP. Questions on the fittings, the manway access, or scheduling delivery for a tank this size? Call 866-418-1777 and we will walk you through it.
