The Snyder Industries 10500 Gallon HDPE Vertical Liquid Storage Tank is a large-volume polyethylene vessel built for bulk water and liquid storage, with a 1.9 specific gravity rating that lets it hold dense liquids well past the weight of plain water. It stands 169 inches tall on a 142 x 142 inch square footprint and holds a nominal 10,500 gallons. If you are sizing a vertical storage tank at this scale, this is a heavy-duty HDPE option for high-volume service, and the matched-size 10500 gallon vertical liquid storage tank buyer's guide compares this exact capacity across applications.
Will this tank work for your site?
The tank is molded from white polyethylene (HDPE) and rated to a 1.9 specific gravity, so the resin and wall thickness are engineered for liquids substantially heavier than water. Filled with water alone, the contents weigh about 87,570 lb; at its maximum rated specific gravity the contents can reach roughly 166,383 lb. That is nearly 78,800 lb more dead load than a water-only read implies, and that maximum figure, not the empty shell weight, is what your pad and foundation engineer needs. The 142 x 142 inch footprint covers about 140 square feet, so at full rated contents the slab carries on the order of 1,180 lb per square foot of average bearing load. Spec the pad for that number, confirm it is level and continuously supported edge to edge, and run the Tank Sizing Calculator with the Tank Sizing Guide to match gallons to your draw and refill cycle.
Sizing, standards, and the mistake to avoid
The most common mistake at this volume is treating the listed specific gravity as a number you can ignore. The 1.9 rating defines the densest liquid the wall is built to carry; it does not mean you should fill to the brim with a heavy fluid. The 10,500 gallon figure is nominal capacity, and usable volume is less once you reserve freeboard per the ASTM D1998 sizing logic. Wall thickness on HDPE vertical tanks is thinnest near the top, where the vapor-saturated headspace sits, and our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through why that zone matters and the D1998 logic behind it. If you are using this tank for fire reserve, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
Freight on a tank this size
A 10,500 gallon tank ships LTL on a flatbed, quoted live to your ZIP. This Snyder unit ships from one of two plants, Lincoln, NE or Philippi, WV, so your freight depends heavily on which origin serves your region: West, Plains, and Midwest destinations generally pull from Lincoln, while East Coast, Mid-Atlantic, and Southeast destinations generally pull from Philippi. Get a real number before you commit by running the Freight Cost Estimator, or call our team at 866-418-1777 to confirm origin, delivery access, and offload requirements for a unit of this height and weight. See the technical drawing on this page for full dimensional detail.
