The Snyder Industries 1900 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 1,900-gallon polyethylene vertical storage tank built to ASTM standards and rated to a specific gravity of 1.9. That 1.9 rating is the whole point of the "Heavy Duty" designation: full of plain water this tank carries roughly 15,846 pounds, the same load a standard 1.0-SG tank of this size would hold, but its structure is rated to a maximum contents weight near 30,107 pounds. For a water buyer that spread is a large built-in safety margin; it is also the top of this tank's rating range, so there is no heavier build to step up to. At 119 inches tall on a 72 x 72 inch footprint it stands just under ten feet, and the black wall resists UV while blocking light transmission to help limit algae growth in outdoor water storage.
Will this tank work for your site?
Plan your foundation around the loaded figure that matches your stored liquid, not the empty shell. The 72 x 72 inch base is 36 square feet, so a full water load puts about 440 pounds per square foot on the pad, and the 30,107-pound maximum rating works out to roughly 836 pounds per square foot. Use those numbers to confirm your soil and pad bearing capacity before you pour. To match capacity to your actual demand, run the figures through our Tank Sizing Calculator and review the Tank Sizing Guide, then use our guide to concrete pad sizing for above-ground polyethylene tanks for the ACI framework behind a base that carries the loaded weight.
Fittings and access
Per the technical drawing on this page, this vertical tank is configured with a flange outlet, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access for interior reach during cleaning and inspection. The lid and manway sizes are listed, but the flange outlet dimension is not, so confirm the flange size, gasket, and bolt pattern against the technical drawing before you order mating fittings or bulkhead gaskets. Check fitting elevations and orientation against your plumbing plan at the same time.
The mistake to avoid
The most common error with a tank this tall is under-building the pad or setting it on ground that is not truly level. A 119-inch column of liquid concentrates significant load on the base, and any tilt or soft spot translates into stress on the tank wall over time. If you are storing fire-reserve or bulk process water, size for freeboard and cold-climate protection deliberately; our writeup on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze protection for remote sites.
This Snyder black vertical storage tank ships by LTL freight from the Chowchilla, California plant only, quoted live to your ZIP code. Because it leaves a single West Coast origin, buyers far from California should pull a rate early through our Freight Cost Estimator or call 866-418-1777 to arrange delivery and confirm accessorial needs like a liftgate or limited-access site.
