The Snyder Industries 210 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 55-inch-tall polyethylene vertical tank on a compact 36 x 36 inch footprint, built to the ASTM standard and rated to a 1.9 specific gravity. That heavy-duty 1.9 rating is the reserve-strength choice: the shell is engineered to hold contents nearly twice as dense as water. For straight water storage (specific gravity 1.0) you are paying for roughly 90% density headroom you will not use day to day, which buys you longevity and abuse tolerance rather than a spec you need to hit. There is no lighter or heavier sibling to trade into here; this is the top of the rating ladder for this size.
Will it work for your site?
At 210 gallons, a full load of water weighs about 1,751 pounds, and the tank is rated to carry up to 3,328 pounds of contents at its 1.9 specific gravity rating. Plan your pad and anchoring around the loaded weight, not the empty tank. The 55-inch height on a 36 x 36 inch base is a tall aspect ratio, so anchor it to the pad against wind and seismic load, especially when the tank sits empty or partially full and the center of gravity works against you. If you are matching volume to a demand schedule, the Tank Sizing Calculator and Tank Sizing Guide walk you through drawdown and refill math for a vertical storage tank of this size, and the Snyder freeboard sizing guide under ASTM D1998 covers the usable-volume and freeboard question on an ASTM-built Snyder tank like this one.
Fittings and access
Per the technical drawing on this page, this tank carries a flange fitting, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access. The flange is your likely bulkhead outlet or drain point, and flange connections seat against a gasket, so confirm the gasket material and bolt pattern on the drawing before you order mating hardware. Because the lid is vented rather than sealed, this is an atmospheric tank only, not rated for pressurized or sealed fill; any inlet float valve or fill line must not create backpressure. The vented lid lets the tank breathe as it fills and draws down so you do not pull a vacuum on the shell, and the 15-inch manway gives you room to reach inside for cleaning and inspection. Check fitting locations and outlet heights against the drawing, since they drive your suction and overflow routing.
Freight to your site
This Snyder black vertical tank ships by LTL freight from the Snyder plant in Philippi, West Virginia. Because it is a large, lightweight freight item, cost is driven by destination and accessorials, so we quote it live to your ZIP rather than list a freight figure. Run your address through the Freight Cost Estimator for a real number, or call us at 866-418-1777 and we will build the quote with you. If you are engineering a cold-climate install or a fire-water reserve, our guides on concrete pad sizing for above-ground polyethylene tanks and fire-water reservoir design for remote sites cover the pad and freeze-protection decisions that go with a black storage tank like this one.
