The Snyder Industries 1300 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a Chowchilla, California-built vertical tank molded in high-density linear polyethylene and rated to a 1.9 specific gravity, which is what earns the "heavy duty" name. It stands 87 inches tall on a 72 x 72-inch footprint, so a 1300-gallon black vertical tank drops onto a level pad without an oversized excavation while still carrying genuinely heavy contents.
Will it work for your site?
The number that matters here is load headroom. Filled with water at roughly 8.34 pounds per gallon the contents weigh about 10,842 pounds, and this tank is rated to carry contents up to 20,600 pounds thanks to the 1.9 specific gravity rating, so the sizing margin works in your favor rather than against you. The black resin is a secondary benefit: it blocks light and discourages the algae growth that plagues translucent tanks in outdoor water storage. Top fittings shown on the technical drawing on this page include an 18-inch polyethylene threaded and vented fitting, a flange, and a manway with a 15-inch access opening for interior inspection and cleaning. The drawing may also show a Snyder SUMO-style fitting location; confirm that, and every fitting, against the drawing before you order anything, because these are shown on the tank, not supplied as loose hardware. Match the flange bolt pattern and gasket size and the 18-inch threaded fitting's mating cap or adapter to the drawing before buying inlet, outlet, or vent hardware, since mismatched mating hardware is the actual failure point.
Foundation, freeboard, and setup
A vertical storage tank this size wants full continuous support. The 72 x 72-inch footprint must sit on a level pad rated for the loaded weight, not on isolated blocking. For a poured base, our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework. On usable volume, treat 1300 gallons as nominal capacity: if you are filling with heavy or thermally active liquid, size your working volume with freeboard per ASTM D1998, as covered in our freeboard sizing guide. Run the totals through our Tank Sizing Calculator and Tank Sizing Guide. If this vertical tank anchors a rural fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection; for greywater or rainwater aggregation, see our water reuse tank topology guide.
The mistake to avoid
The common error on a heavy-duty vertical tank is under-building the pad. The 1.9 specific gravity rating means nothing if the base cannot carry a fully loaded storage tank, and an unlevel or partial support can distort the shell over time. Pour and level the foundation for the full loaded weight before the first fill.
