The Snyder Industries 550 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a crosslinked polyethylene vertical tank built for demanding storage where a standard water tank would be under-specified. It holds 550 gallons in a 48-inch by 48-inch footprint standing 75 inches tall, and the crosslinked (XLPE) wall carries a 1.9 specific gravity rating. It is built and shipped from Snyder's Chowchilla, California plant, so West Coast buyers see the shortest freight lane and East Coast buyers should plan for a longer LTL haul. The 1.9 SG rating is the headline number to check against your application before you order.
Will it work for your site
Filled with plain water this tank carries about 4,587 pounds of contents; at its 1.9 specific gravity rating the manufacturer's rated contents ceiling is 8,715 pounds. Use those two weights, not just the gallon count, when you size the concrete pad or foundation beneath it. The 48 x 48-inch footprint and 75-inch height determine both the pad dimensions and the overhead clearance you need for the lid and fill plumbing. Our Tank Sizing Calculator and Tank Sizing Guide walk through matching this vertical storage tank to your volume and layout; if you are pouring a slab, the concrete pad sizing guide covers the ACI framework for above-ground polyethylene tanks. To translate gallons into usable volume with proper freeboard, the ASTM D1998 freeboard guide shows why you size by contents, not the nameplate number.
Fittings and access
This tank is configured with a flange fitting, an 18-inch polyethylene threaded and vented opening, and a manway with 15-inch access for interior reach during cleaning or inspection. Confirm the fitting and vent layout against the technical drawing on this page before finalizing your inlet, outlet, and vent plumbing, since the vented opening matters for proper filling and draining. The flange and manway are the two service points where sealing matters most, so call 866-418-1777 to confirm gasket and seal specifics before you buy. The natural white translucent wall lets you eyeball the liquid level from outside without opening the tank.
Why XLPE here
Crosslinked polyethylene is a heavier-duty wall than standard HDPE, and the crosslinking is what supports the 1.9 specific gravity rating and the heavy-duty service this tank is rated for. If you are deciding between materials, our guide on Snyder XLPE vs HDPE explains when crosslinking earns its place. For fire-protection and rural water reservoir sizing, the fire-water reservoir design guide covers NFPA 22 discipline and freeze protection for cold-climate service.
