The Snyder Industries 6500 Gallon HDPE Vertical Liquid Storage Tank is a 153-inch-tall vertical storage tank on a 120 x 120-inch footprint, molded from white polyethylene and carrying an ASTM specific gravity rating of 1.4. At 6,500 gallons in a single vessel, it is sized for bulk water, fire-water reserve, agricultural, and industrial liquid storage where you want one large vertical tank instead of a manifold of smaller ones. The 1.4 SG rating tells you exactly how much liquid this shell is built to hold: a full charge of water weighs about 54,210 lb, and the tank is rated to carry contents up to 75,894 lb, so the headroom in that rating is what lets it hold liquids denser than water without exceeding the wall's design.
Will it work for your site?
Plan the pad and the math before the tank arrives. The 120 x 120-inch footprint needs a level, fully supporting foundation - and the pad must be rated to the 75,894 lb max-contents ceiling, not the 54,210 lb water figure, if you will ever run a liquid denser than water. Size to the water weight alone and you under-build the foundation for the tank's own rating. A vertical tank of this size develops real hydrostatic head over 153 inches of fill, so the SG number matters: at 1.4 SG this shell accepts liquids up to 1.4 times the density of water, and the 75,894 lb max-contents figure is firm. If your liquid exceeds 1.4 SG, call us to confirm a correctly rated vessel before ordering - do not derate this shell by guesswork. Run your volumes through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 6,500 gallons is the working volume you actually need, not the brim-full number, before you set the pad.
Fittings and configuration
Fitting and bulkhead layout - fill, outlet, vent, and any manway - is confirmed per order on a tank this size. Call 866-418-1777 with your fill, outlet, and vent requirements before you buy so we set the right configuration the first time, and review the technical drawing on this page for the tank's dimensional profile.
The mistake to avoid on a tank this size
The error that costs the most here is treating wall thickness as uniform. On a tank this tall, the thinnest, most-stressed section sits up at the vapor-saturated headspace, not down at the liquid line where most inspections focus - which is why the design follows ASTM D1998 sizing logic for the wall profile. Our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through where premature failures originate and why liquid-side inspection misses them. If this is going into fire-protection duty, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites. For more on the same vertical liquid storage family in a similar size, see our related 6500 gallon vertical liquid storage tank buyer's guide (note that guide covers a slightly different 120 x 147 configuration; this listing is the 120 x 120, 153-inch tank).
Freight and ordering
This is a 6,500-gallon vertical HDPE storage tank, so it ships LTL on its own and freight is quoted live to your ZIP - it is not included in the list price. Origin proximity is the single biggest freight variable on a tank this size, and Snyder builds this one in two plants - Lincoln, NE and Philippi, WV - so we ship from whichever named plant is nearest you to keep the LTL run short. Get a real number with the Freight Cost Estimator, or call 866-418-1777 and we will confirm the closest origin, lead time, and delivery to your site. Have your delivery ZIP and any access limits (lift-gate, narrow road, no dock) ready when you reach out.
