The Snyder Industries 15,000-gallon HDPE vertical liquid storage tank is built for high-volume water and bulk liquid service where a single large-footprint reservoir replaces a bank of smaller tanks. Molded from white polyethylene with a 1.4 specific gravity rating, this vertical storage tank stands 234 inches tall on a 143 x 143 inch footprint and carries an ASTM certification consistent with Snyder's vertical tank line.
Will it work for my application?
This is a 15,000-gallon vertical tank, so plan your pad and access around real numbers, not just the gallon figure. Water at full capacity weighs roughly 125,100 lbs, and the tank is rated to a maximum contents weight of 175,140 lbs at its 1.4 specific gravity rating. Those two numbers drive everything: foundation design, anchoring, and the density ceiling of whatever you store. The 1.4 SG rating means the wall is engineered for liquids up to 1.4 times the weight of water, which comfortably covers potable and process water plus many denser solutions. If your liquid exceeds 1.4 SG, such as heavy brines, some acids, or slurries, this tank is not rated for it, so call 866-418-1777 before ordering and we will match you to a higher-SG-rated vessel. To size a system from scratch, run your volume and turnover through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a single 15,000-gallon vessel versus a multi-tank layout, and review the 15,000 Gallon Vertical Liquid Storage Tank buyer's guide for siting, plumbing, and inspection detail.
Wall thickness, head, and the 234-inch column
On a 234-inch liquid column, hoop stress at the base is the design driver. The wall is engineered thicker low and thinner toward the vapor-saturated headspace at the top, and that headspace region is exactly where premature failures tend to originate and where ASTM D1998 sizing logic and inspection are most often misread. The deep-dive on HDPE tank wall thickness at the vapor-saturated headspace explains why liquid-side inspection alone misses it. There is a second consideration unique to a tall, high-aspect-ratio vessel: empty, a 234-inch tank on a 143-inch footprint is wind-vulnerable, so design hold-downs for the empty condition, not just the 175,140 lb full-rated load. If this tank will serve fire-water reservoir or freeze-prone duty, size and protect it deliberately; the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate engineering.
Fittings and what to confirm before you order
The technical drawing on this page is the authority for fitting locations, manway placement, and exact mold dimensions. Fitting count, thread sizes, manway, and bulkhead locations are not configured in this listing, so use the drawing to lay out your inlet, outlet, overflow, and vent connections, and we will confirm that layout by part number before the order ships. Call 866-418-1777 to walk through your connection plan on a 15,000-gallon vertical storage tank rather than discovering a mismatch on delivery day.
Freight
A tank this size ships LTL, and freight is quoted live to your ZIP rather than bundled into the list price. This unit ships from the Snyder plant in Lincoln, NE, and a 234-inch-tall vertical tank requires open-deck or specialized handling plus equipment to offload on site, so plan your delivery window and unloading method in advance. Get a real number with the Freight Cost Estimator by entering your delivery ZIP, or call us at 866-418-1777 to talk through access, offload, and lead time before you buy.
