The Snyder Industries 550 Gallon Vertical Storage Tank is a black, crosslinked linear polyethylene (XLPE) vertical tank built for heavy-duty water and liquid storage. It stands 75 inches tall on a 48 x 48 inch square footprint, holding 550 gallons in a single upright cylinder. The XLPE resin is molded to the ASTM standard and carries a 1.9 specific gravity rating, which means the wall is engineered to hold contents substantially heavier than water without deforming or fatiguing over a long service life.
Will it work for your site?
Filled with water at 8.34 lb per gallon, this tank carries roughly 4,587 pounds of contents, and its 1.9 SG rating raises the maximum rated contents weight to about 8,715 pounds. That gap is usable headroom: at 1.9 SG the wall is rated to carry liquids up to roughly 1.9 times the density of water, so you are not capacity-limited if you later store a denser fluid, subject to confirming wall compatibility for that duty. Plan your foundation around the full-weight numbers, because thousands of pounds concentrate on a 48 x 48 inch footprint and the tank needs a level, load-rated pad. Just as important, a 75-inch-tall tank on that footprint is top-heavy and wind-vulnerable while empty, so strap or anchor it to the pad rather than relying on weight alone. If you are sizing for a fire-water reservoir or a bulk storage run, work the numbers with our Tank Sizing Calculator and Tank Sizing Guide, and see the fire-water reservoir design guide for NFPA 22 sizing and cold-climate freeze protection. For the concrete work, our pad sizing guide covers the ACI framework for above-ground poly tanks.
Fittings and access
This vertical storage tank is configured with a flange fitting, an 18-inch PE threaded and vented lid, and a manway with 15-inch access for interior reach during cleaning and inspection. Confirm the exact fitting locations and heights against the technical drawing on this page before you plumb your inlet and outlet, so connections land where your piping run needs them. Make up the flange evenly against the poly wall with the correct gasket and torque it in a cross pattern so it seats without distorting the plastic. Keep the 18-inch lid vented in service, since a sealed top can pull a vacuum on the wall during fast drawdown.
XLPE and black-resin water storage
Crosslinked polyethylene resists impact and stress cracking better than standard HDPE, which is why Snyder rates this wall to 1.9 specific gravity. The black, opaque resin blocks light transmission, which suppresses algae growth in stored water and shields contents from UV. If you are weighing crosslinked construction against a linear HDPE tank, our breakdown of Snyder XLPE vs HDPE explains where crosslinking earns its place, and the Captor freeboard sizing guide covers usable-volume planning. This is listed as a water and general-storage tank; verify wall compatibility for any duty beyond water before filling.
