The Snyder Industries 8000 Gallon HDPE Vertical Liquid Storage Tank is a 186-inch-tall white polyethylene vessel built on a 120 x 120-inch footprint, rated for liquids up to a 1.5 specific gravity and certified to ASTM standards. If you are sizing a vertical storage tank for bulk water, fire-water reserve, or another heavy-duty industrial application, this is one of the largest single-vessel polyethylene options Snyder offers, and the 1.5 SG wall rating gives you real headroom above plain water service.
Will it work for your application?
At 8,000 gallons, a full tank of water weighs roughly 66,720 lb, and the 1.5 specific-gravity rating means the wall is engineered to hold contents weighing up to about 100,080 lb. That is roughly 33,360 lb of additional content capacity above plain water - so the same vessel can serve denser liquids like brine, some fertilizers, or fire-retardant concentrate up to about 1.5 SG without stepping up to a different tank. A buyer doing density math should run those numbers against the wall rating using the Tank Sizing Calculator, and the Tank Sizing Guide will confirm this vertical HDPE storage tank matches your volume and density requirements before you commit. The footprint is a full 120 x 120 inches, so plan your pad accordingly.
Fittings and what mates to them
Per the technical drawing on this page, this vertical tank is fitted with:
- Flange (seats on a gasket - select EPDM or Viton to your stored liquid)
- 18-inch PE threaded and vented fitting (takes a matching PE threaded cap or vent)
- Manway with 15-inch access opening for inspection and cleaning
Spec the gasket and mating hardware to your service rather than to plain water - the right elastomer is what keeps the flange sealed under load over the life of the tank.
How does it ship?
A tank this size ships LTL freight from Snyder's plant in Chowchilla, California, the nearest manufacturing point for this SKU. At 186 inches tall on a 120 x 120-inch base, this is a tall, wide LTL load that typically needs a crane or forklift to offload and clear overhead at the delivery point, set onto a level, full-bearing pad. Because freight on a vessel this size varies by destination, we quote it live to your ZIP rather than baking it into the list price. Run your delivery address through the Freight Cost Estimator for an accurate LTL number, or call 866-418-1777 and we will quote it for you.
The mistake to avoid
The most common error on a tank this large is treating the pad and the wall rating as afterthoughts. With nearly 67,000 lb of water bearing down on a 120 x 120-inch base, the foundation has to be engineered, level, and full-bearing under the entire footprint - see our guide on concrete pad sizing for above-ground polyethylene tanks for the ACI framework. Equally important: this is a 186-inch-tall HDPE wall, and the most premature failures originate at the vapor-saturated headspace near the top, not down at the liquid line - our breakdown of HDPE wall thickness at the headspace and the ASTM D1998 sizing logic is worth reading before you put this tank into service. If this vessel is part of a rural or remote fire-water reserve, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
