The Snyder Industries 4600 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene vertical storage tank built for high-volume above-ground bulk water and liquid storage. It measures 10 feet in diameter with a 116-inch overall height including the dome, sits on a 120 x 120 inch footprint, and carries a 1.9 specific gravity rating. The three things worth getting right before you buy are whether it fits your site and duty, how it ships, and the one detail operators most often overlook on a vertical tank this size.
Does it work for your site?
At 4,600 gallons of nominal capacity, a full load of water alone weighs roughly 38,364 pounds, and at the tank's 1.9 specific gravity rating the maximum rated contents weight climbs to 72,892 pounds. Those numbers drive your pad, not the empty tank weight. A vertical tank this large concentrates that mass over a 10-foot clear-diameter footprint, so a properly engineered concrete pad is not optional. Our concrete pad sizing guide walks through the ACI 360R-10 framework and where the ACI 318 boundary applies for above-ground polyethylene tanks. The 1.9 rating is also real headroom for water service: because the same vessel is rated to hold liquids up to 1.9 specific gravity, it can carry heavier solutions like brine or some liquid fertilizers without stepping up to a different tank, with pad and freight sized to your actual contents. If you are still confirming capacity for your demand, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide first.
Fittings and access
Per the technical drawing on this page, this vertical tank is configured with a flange fitting, an 18-inch polyethylene threaded/vented fitting, and a manway with 15-inch access. The 18-inch PE threaded/vented fitting accepts a standard threaded bulkhead and vent assembly, and it matters for any application where you fill or draw down quickly, since the headspace has to breathe to avoid pulling a vacuum or pressurizing the dome. The flange seats on a gasket, so confirm the gasket material is compatible with your stored liquid before commissioning. The 15-inch manway supports cleanout and inspection on a vessel this large, and its gasketed lid has to be reseated and torqued to spec after every entry to hold a reliable seal. Review the technical drawing on this page to confirm fitting locations and elevations against your plumbing layout before you set the tank.
The mistake to avoid on a tank this size
The detail operators miss is at the top of the tank, not the bottom. HDPE wall thickness in the vapor-saturated headspace is where premature failures tend to originate, and routine liquid-side inspection misses them. If you are sizing for long-term water storage, our guide on HDPE tank wall thickness and ASTM D1998 sizing logic explains why, and ASTM D1998 is the standard behind this tank's wall construction. For fire-protection reservoirs in rural or remote service, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
This Snyder vertical storage tank ships LTL freight from the Chowchilla, California plant, quoted live to your delivery ZIP rather than bundled into the listed price. Because it is a 10-foot-diameter oversize load, plan for offload equipment and clear site access before you book — delivery on a tank this size needs both. Get an exact number from our Freight Cost Estimator, or call 866-418-1777 and we will work out delivery, offload, and access details with you.
