The Snyder Industries 4500 Gallon Vertical Storage Tank (model 7000400N48) is a black, crosslinked linear polyethylene (XLPE) vertical tank rated to a 1.9 specific gravity for heavy-duty water and dense-liquid storage. It stands 91 inches tall on a 143 x 143 inch footprint and holds 4,500 gallons. Made from ASTM XLPE, this is a serious bulk-water reservoir sized for fire-protection stores, agricultural supply, rural water supply, and industrial process water.
Does it fit your job?
Check the physical fit first: 91 inches tall on a 143 x 143 inch footprint, so confirm door, gate, and pad clearance before you order. Full of plain water this tank carries roughly 37,530 pounds of contents, and its 1.9 specific-gravity rating means it is engineered to hold up to about 71,307 pounds of denser liquid at full volume. Since plain water sits at a specific gravity of 1.0, that 1.9 rating is built-in headroom, not a limitation — you are buying a wall over-spec'd for water duty. That heavy rating is the reason to choose crosslinked polyethylene here: XLPE builds a tougher, more impact- and stress-crack-resistant wall than standard HDPE when you are storing thousands of pounds of liquid against the tank floor. If you are weighing the two wall types, our guide on Snyder XLPE vs HDPE covers when crosslinking earns its place. Not sure 4,500 gallons is the right volume? Run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
Fittings and access
Per the technical drawing on this page, this vertical storage tank comes configured with a flange, an 18-inch PE threaded and vented top fitting, and a full manway with 15-inch access for interior entry, cleaning, and inspection. Confirm the fitting locations and elevations against the technical drawing before you set your plumbing, since inlet, outlet, and vent placement drive how you tie the tank into your system. Confirm gasket and bolt-kit requirements for the flange connection when you call, since those are quoted with the tank rather than assumed. Because the walls carry that full 71,307-pound rated load, the tank must sit on a properly engineered, level pad — our write-up on concrete pad sizing for above-ground polyethylene tanks covers the ACI framework so the foundation matches the load.
Common mistakes to avoid
The biggest one on a tank this size is skipping vent capacity or freeboard planning. The included 18-inch vented fitting is there for a reason: a large tank filled or drained quickly can pull or push enough air to damage the shell if the vent is undersized or blocked. If this reservoir feeds a private fire-protection system, size the usable volume and freeze protection deliberately rather than assuming nameplate gallons — the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate protection. And do not confuse total capacity with working volume; the freeboard sizing write-up explains the real volume you can actually use.
