The Snyder Industries 4600 Gallon HDPE Vertical Liquid Storage Tank is a 120-inch-diameter polyethylene vertical storage tank built to the ASTM standard for above-ground water and liquid service. Molded in white HDPE with a 1.5 specific gravity rating, this Snyder vertical tank is sized for bulk water reserves, rainwater collection, fire-water storage, and process water where you need real capacity in a footprint you can pour a pad for.
Will this tank work for your job
The tank holds 4,600 gallons and stands 116 inches tall on a 120 x 120 inch footprint - a true 10-foot square pad. Filled with water, the contents weigh roughly 38,364 pounds, so your concrete pad and subgrade have to carry that load plus the tank itself. The 1.5 specific gravity rating is the real value here: this wall is rated to carry liquids up to a maximum rated contents weight of 57,546 pounds, so it handles denser liquids - brines, fertilizer solutions, and many process liquids up to 1.5 SG - without stepping up to a heavier tank than a water-only 1.0 or 1.1 rated vessel would require. Size your pad against that 57,546 lb figure if you ever run anything denser than water. Before you commit, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide so the height, diameter, and weight all match your site.
Fittings and access
Per the technical drawing on this page, this vertical storage tank is configured with a flange, an 18-inch polyethylene threaded/vented fitting, and a manway with 15-inch access for inspection and cleaning. That 18-inch threaded/vented fitting governs your fill-and-draw vent path, so don't blank it off - a sealed tank with no vent will collapse or balloon as the level changes. Confirm the fitting positions against the technical drawing before you set the tank, because relocating a fitting after molding is not something you want to discover on install day. Fittings seat on gaskets, and those seals are the wear item: water service is straightforward, but if you run a specialty liquid near the 1.5 SG ceiling, verify the gasket material suits your stored liquid before filling.
Freight and how to order
This Snyder HDPE storage tank ships LTL freight from the Chowchilla, California plant. At 116 inches tall it moves as oversized freight, so the cost depends entirely on your delivery ZIP and site access. Get an exact number from the Freight Cost Estimator for your ZIP, or call us at 866-418-1777 and we will quote the lane and walk you through delivery requirements. For wall-thickness and ASTM D1998 sizing background, the HDPE tank wall thickness guide and the concrete pad sizing guide are worth a read before you build the foundation. Weighing single- versus double-wall containment at this volume, see the Snyder Captor double-wall freeboard sizing guide, and if you are planning a rural reserve or fire-water store, our fire-water reservoir design guide covers the sizing discipline.
