The Snyder Industries 1000 Gallon HDPE Vertical Liquid Storage Tank holds 1,000 gallons of water or general liquid, molded from high-density linear polyethylene in white and rated by Snyder to a 1.9 specific gravity. That 1.9 number is the first thing to read: water is specific gravity 1.0, so a shell built to 1.9 carries roughly 90% more weight than water and covers denser liquids and many solutions without stepping up to a different tank. Confirm your liquid's specific gravity is at or below 1.9 before you order, and this vertical storage tank will do the job with real headroom to spare.
Will it work for your liquid?
Start with weight. Filled with water this tank carries roughly 8,340 lb of contents; at its full 1.9 specific gravity rating it is built to hold up to 15,846 lb of liquid. That load lands on a 74 x 74-inch footprint, which concentrates a lot of weight on a small area, so set it on a level, engineered concrete pad sized to the full-load number, not bare soil or gravel. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the pad and capacity match your application before you order.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange outlet, an 18-inch polyethylene threaded vented fitting, and a manway with a 15-inch access opening. The flange is your connection point, so size it against your pipe before you plumb it; the 15-inch manway opening sets what fits through for interior inspection and cleaning. The vented fitting matters on an atmospheric vertical tank like this one, since a sealed tank that is filled and drained can pull a vacuum or build pressure, so keep the vent clear in service. One step buyers skip: the polyethylene wall and the elastomer gaskets at the flange and manway are rated separately, so confirm the seal material at those joints suits your stored liquid, not just the tank shell. Confirm the fitting locations and outlet height against the technical drawing on this page before you cut any pipe.
The HDPE detail most operators miss
On a molded HDPE vertical tank, the wall is thickest at the base and thinnest near the top, and the vapor-saturated headspace at the top is exactly where premature failures tend to originate even when the liquid-side wall still looks fine. Our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through the ASTM D1998 sizing logic behind that and why a liquid-side inspection can miss it. Verify the exact height and diameter against the technical drawing on this page before ordering. If you are weighing this against other 1000 gallon vertical storage tank configurations, our buyer's guides for the 72 x 66, 64 x 81, and 64 x 80 versions help you match dimensions to your space.
