The Snyder Industries 6500 Gallon HDPE Vertical Liquid Storage Tank is a 153" tall vertical storage tank built on a 120" x 120" footprint, molded from polyethylene in white. It carries a 1.9 specific-gravity rating, which is the spec that matters most on a vertical tank this large: at full water it holds roughly 54,210 lbs of liquid, and the 1.9 SG wall is rated to carry contents up to about 102,999 lbs. That headroom is why this size shows up in fire-water reservoirs, bulk municipal and agricultural water, and heavier-than-water storage where a 1.0 or 1.5 SG vertical tank would be underbuilt.
Does it fit your application?
Sizing a 6500 gallon vertical tank is mostly a weight-and-pad exercise, not a volume one. Plan the slab for the loaded weight: about 54,210 lbs full of water, and up to 102,999 lbs if you fill it with a denser liquid at the rated 1.9 SG. The 120" x 120" footprint and 153" overall height drive your pad size, fill-line height, and offload clearance. Fitting, bulkhead, and gasket configuration on a tank this size is confirmed per order, so call to spec outlets, fill, and vent before you commit. If you are comparing this 120" x 120" build against the taller 120" x 147" version of the 6500-gallon family, or working out usable volume versus rated capacity, the Tank Sizing Calculator and our Tank Sizing Guide walk through footprint, freeboard, and weight loading. The 6500 Gallon Vertical Tank buyer's guide lays out the size family side by side.
Why the 1.9 SG rating matters here
The most common mistake on a vertical storage tank this large is treating specific gravity as a formality. SG sets how much weight the wall is rated to carry, and on a 6500 gallon HDPE vertical that is the difference between a long service life and a wall overstressed at the bottom course. At 1.9 SG this wall is rated to roughly 102,999 lbs of contents versus about 54,210 lbs at full water — so if you are storing anything denser than water, this 1.9 build is the right call, and a 1.0 or 1.5 SG vertical would be underbuilt for the same job. This tank carries ASTM certification; ASTM D1998 is the governing standard for polyethylene upright storage tanks, setting wall thickness as a function of height and stored-liquid density. For background on how wall thickness and the D1998 sizing logic relate to long-term service, our guide on HDPE tank wall thickness and ASTM D1998 sizing logic walks through the inspection points operators miss. For fire-protection use, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
Freight on a 6500 gallon tank
A tank this size ships LTL freight on its own, and the rate depends heavily on how far it travels. This Snyder HDPE storage tank ships from one of two Snyder plants — Lincoln, NE or Philippi, WV — confirmed per order, and your freight cost depends on which serves your ZIP. Get an exact number before you buy: run your ZIP through the Freight Cost Estimator for a live LTL quote, or call 866-418-1777 and we will quote it with you. Confirm site access for a tank at 153" tall and 120" wide — delivery, offload, and the path to the pad all need that clearance.
