The Snyder Industries 8500 Gallon HDPE Vertical Liquid Storage Tank is a vertical storage tank molded from polyethylene with an ASTM-certified build for above-ground liquid storage. It stands 194 inches tall - about 16 feet 2 inches - on a 120-by-120-inch footprint, a 10-foot-square base, and carries a 1.9 specific gravity rating, which means it is engineered to hold heavier-than-water contents up to that density. For most operators this is a bulk fresh-water, fire-water, or process-water reservoir where a tall vertical column and a large footprint matter more than portability.
Will this 8500-gallon vertical tank work for your site?
Start with the load on your pad. Filled with water (specific gravity 1.0) this tank carries roughly 70,890 pounds of contents; at its maximum 1.9 SG rating it is engineered for up to 134,691 pounds of contents. Those are the numbers your concrete and soil bearing have to support, so size the pad before you size anything else. At 120 inches wide and 194 inches tall this is also an over-dimensional load to receive - confirm the tank will clear your roof line, doorways, and overhead obstructions, and plan a staging spot before it arrives. The drawing for this model confirms a flange, an 18-inch polyethylene threaded/vented fitting, and a 12-inch by 24-inch manway-class opening; check those locations and the fitting layout against your plumbing on the technical drawing on this page before you order. The 18-inch fitting is threaded and vented PE, so mate it with a PE-compatible threaded fitting and a gasket rated for polyethylene - do not torque it like a metal-tank flange.
Sizing the pad and the structure
Because this is a tall, large-footprint vertical tank, the structural questions come first. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 8500 gallons matches your real draw-down and reserve needs, then move to the pad. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework and the ACI 318 boundary for a footprint and contents weight in this range. If you are specifying this as a fire-water reservoir, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
Wall thickness on a tank this tall is not uniform top to bottom, and HDPE thins where it matters least to a casual inspection. Our deep-dive on HDPE tank wall thickness and the ASTM D1998 sizing logic explains why premature failures originate at the vapor-saturated headspace and why a liquid-side inspection misses them. The second mistake is under-rating the contents: this is a 1.9 SG tank, so match the specific gravity rating to the density of your liquid. Buying a 1.9 SG tank for water service also means the wall carries substantial reserve - rated for 134,691 pounds of contents against the 70,890 pounds of a full water load - so you keep headroom to move to a denser liquid up to 1.9 SG later without re-tanking.
