The Snyder Industries 1100 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene vertical storage tank rated to ASTM standards, standing 90 inches tall on a 64 x 64 inch square footprint. It carries a 1.5 specific gravity rating, which is the headroom that determines whether this tank is right for what you plan to store. If you only need to hold water, this vertical tank gives you full 1100-gallon usable capacity with real margin to spare on the density rating.
Will it work for your application?
At 90 inches tall with a 64 x 64 inch footprint, confirm your pad, doorway, and overhead clearance before ordering. Filled with water, the contents alone weigh roughly 9,174 pounds (1,100 gallons of water), plus the tank's own weight, so the slab underneath has to be engineered and level for that load. The 1.5 specific gravity rating means the tank itself is built to carry contents up to a maximum rated weight of about 13,761 pounds, giving you a real margin above plain water for heavier liquids. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 1100-gallon vertical tank to your draw-down and refill cycle before you commit.
The specific-gravity mistake to avoid
The single most common error with a vertical storage tank like this is reading the gallon number and ignoring the 1.5 specific gravity rating. That rating tells you how dense a liquid the wall thickness is sized to hold over the tank's life. Plain water sits at 1.0, so water service has a comfortable margin here; if your liquid is heavier than water, check its specific gravity against the 1.5 rating before you fill. For anything heavier than water or any service that calls for secondary containment, the Snyder Captor double-wall freeboard sizing guide walks through the density and freeboard math for a contained step-up. The same physics drives wall-thickness behavior at the top of the tank, where the vapor-saturated headspace is where premature HDPE failures originate; our guide on HDPE tank wall thickness and ASTM D1998 sizing logic walks through why liquid-side inspection misses it and how the rating is engineered.
Sizing it into a larger system
For operators putting this 1100-gallon HDPE tank into a fire-protection or reservoir role, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites. If you are cross-shopping Snyder's other 1100-gallon vertical configurations, note this one measures 90 inches tall on a 64 x 64 inch footprint, while the natural-white version covered in the 1100 gallon natural-white vertical buyer's guide is a different 87 x 53 inch tank — so check which dimensions fit your site before you decide.
