The Snyder Industries 550 Gallon Heavy Duty Vertical Storage Tank is a natural white, crosslinked polyethylene (XLPE) vertical storage tank built to the ASTM standard for above-ground bulk storage. It carries a 1.9 specific-gravity rating, meaning the tank wall is engineered to hold contents up to 1.9 times the density of water without derating the shell. That 1.9 rating is what separates this XLPE tank from a standard water-only vertical, and it is the first thing to confirm against what you actually plan to store: if your contents exceed 1.9 specific gravity, this tank is not rated for them.
Will it work for your site?
This is a 46-inch-tall storage tank on a 64 x 64 inch square footprint, holding a nominal 550 gallons. Filled with water, contents weigh 4,587 lb; at the full 1.9 specific-gravity rating the tank is rated to carry up to 8,715 lb of contents. Use those two numbers to size your pad and confirm the ground can bear the loaded weight across the 64 x 64 inch footprint. Putting 550 gallons into a deliberately squat 46-inch-tall shell lowers the center of gravity for windy or seismic sites, and the low fill height keeps top-fill and gravity-feed plumbing easy to reach without a tall ladder or platform. If you are still choosing a capacity, run your usage through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit. Refer to the technical drawing on this page for outlet and fitting locations.
Why crosslinked polyethylene here
Crosslinked polyethylene is a different resin family than standard HDPE. The crosslinking bonds the polymer chains, which raises impact and environmental-stress-crack resistance and is why XLPE tanks carry the higher 1.9 specific-gravity rating. That makes this vertical a strong choice for heavier-than-water bulk storage where an HDPE water tank would be underrated. Our guide on Snyder XLPE vs HDPE walks through exactly when crosslinking earns its place, and XLPE verticals are also common in fire-water and reservoir duty covered in our fire-water reservoir design guide.
The mistake to avoid
The common error on a 1.9-rated vertical is treating the 8,715 lb maximum as the full foundation load. It is not — that figure is contents only. Add the tank's own empty weight (read it off the drawing or spec) to the 8,715 lb before you pour, and size the pad for that total, not the 4,587 lb water weight. Then follow the framework in our concrete pad sizing guide so a tank sized correctly for the liquid does not fail on an undersized or unlevel base.
