Snyder Industries 5500 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

The Snyder Industries 5500 Gallon HDPE Vertical Liquid Storage Tank is a 132-inch-tall white polyethylene vertical storage tank built for high-volume water and liquid storage. It measures 120 inches in diameter with a 120.0 x 120.0-inch footprint, so a 10-foot-square pad anchors it cleanly. Carrying ASTM certification and a 1.9 specific gravity rating, this Snyder vertical tank is rated for liquids well denser than water, which gives you real headroom on what it can hold.

Will it work for your site?

At 5,500-gallon nominal capacity, a full charge of water weighs 45,870 lb, and the tank is engineered to a maximum rated contents weight of 87,153 lb at its 1.9 specific gravity rating. That spread matters: the structural ceiling is nearly twice the weight of plain water (87,153 lb vs 45,870 lb), so this same tank covers liquids up to 1.9 specific gravity without stepping up to a heavier-walled vertical. That is one of the highest SG ratings you will see on a polyethylene vertical, which is why this model shows up under searches for a heavy-duty HDPE vertical storage tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 5,500 gallons matches your drawdown and refill cycle. For denser-than-water service, required freeboard reduces usable volume below the nameplate, so size to your drawdown — the Snyder Captor freeboard sizing guide walks the ASTM D1998 density and usable-volume math.

Pad and installation before delivery

Size your foundation for the loaded weight, not the empty shell. A 120 x 120-inch footprint over a 45,870 lb water load is a meaningful bearing demand, and a vertical this tall is unforgiving of an out-of-level or undersized pad. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework and where the ACI 318 boundary applies, and the HDPE wall thickness and ASTM D1998 sizing logic guide explains the certification this tank carries.

The mistake to avoid

Do not under-build the pad on the assumption that a "water tank" is light. The mistake operators make on tall verticals is sizing the foundation to the empty shell and ignoring that a full charge puts more than 45,000 lb of water on a 10-foot square. Get the pad flat, level, and rated first; everything downstream depends on it. The second thing to confirm before you order: fitting and gasket sizing is not published in this listing data, so do not assume a standard outlet location or bulkhead size — verify nozzle layout against the technical drawing on this page or by phone before you buy bulkhead fittings or gaskets. If this is fire-water duty, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection for this class of polyethylene reservoir.

This Snyder vertical ships LTL freight, quoted live to your ZIP, from whichever Snyder plant is nearest you — Lincoln, NE or Philippi, WV. That dual Midwest and Mid-Atlantic footprint means buyers on either side of the country get quoted from the closer origin, which materially lowers LTL cost versus a single-plant tank.
