The Snyder Industries 3000 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene vertical storage tank built and certified to ASTM standards, standing 111.3 inches tall on a 96 x 95.6 inch footprint. With a 3000-gallon capacity and a 1.4 specific gravity rating, this is a full-size unit for bulk water storage, irrigation supply, fire-water reservoir duty, and other moderate-density liquid storage. It holds a real 3000 gallons without forcing you up into the cost and weight of fiberglass or steel.
Will this vertical storage tank work for your site?
Plan your slab and your fill logic around real numbers. Filled with plain water, the tank carries roughly 25,020 lb of contents, and at its full 1.4 specific gravity rating it is engineered for up to 35,028 lb of liquid weight. That load lands on a 96.0 x 95.6 inch footprint, so your pad has to be flat, fully supporting, and rated for the static weight before you start filling. Run your volume and foundation numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm the unit fits both your target capacity and your pad. For rural fire-protection storage, the fire-water reservoir and NFPA 22 sizing guide walks through how a polyethylene tank this size fits a private fire stack.
Fittings and inspection access
The fitting scheme on this tank, shown on the technical drawing on this page, is three named features: an 18" PE threaded/vented fitting for fill and venting, a flange, and a manway with a 15" access opening for interior inspection and cleaning. Confirm your inlet, outlet, and vent placement against the technical drawing before you set the tank, because relocating plumbing on a 3000-gallon vertical after placement is a job nobody wants to repeat. Note that the chemical compatibility of the flange and the threaded fitting and their seals must be confirmed separately from the HDPE shell itself, since the fittings and gaskets, not just the tank wall, govern what you can safely store long term.
The 1.4 specific gravity rating, and the mistake to avoid
The most common sizing error on a vertical storage tank like this one is reading the gallon number and ignoring the specific gravity. This tank is rated to 1.4 SG, meaning the wall is built to hold a liquid up to 1.4 times the weight of water. Plain water sits at 1.0, so water service leaves a comfortable margin against the 35,028 lb rated contents ceiling. If you are storing anything denser, do the weight math against that 1.4 limit before you commit, and verify long-term compatibility against the manufacturer's chemical-resistance data for both the tank and its fittings. For the engineering behind how HDPE wall thickness is sized and where vapor-side failures actually start, read the HDPE wall thickness and ASTM D1998 sizing guide before you finalize. If your application calls for secondary containment or higher-density duty than a single-wall tank covers, the Snyder Captor double-wall freeboard guide covers the double-wall path.
