The Snyder Industries 200 Gallon ASTM Black Heavy Duty Vertical Storage Tank (SKU 1008000N51) is a 200-gallon black polyethylene vertical tank built to the ASTM standard, standing 53 inches tall on a compact 36 x 36 inch square footprint. It carries a 1.9 specific gravity rating, the number most buyers skip but that actually answers how heavy a liquid this tank is engineered to hold. For plain water at roughly 8.34 pounds per gallon, a full tank weighs about 1,668 pounds, and the wall is rated to carry contents up to 3,169 pounds — that works out to liquids near 15.8 pounds per gallon, or 1.9 times the density of water. That structural headroom is why the 1.9 SG rating matters more than the gallon count when you match a tank to a job.
Will it work for your site?
At 53 inches tall and 36 inches square, this heavy-duty vertical storage tank is sized for tight pads, corners, and doorways where a wider 200 gallon tank will not fit. The black polyethylene wall blocks light, which suppresses algae growth in stored water far better than a translucent tank — a common reason it is chosen for outdoor and long-dwell water storage. Confirm the 53-inch height and 36 x 36 inch footprint against your space and plumbing before ordering, and run your numbers through our Tank Sizing Calculator or read the Tank Sizing Guide if you are still deciding between capacities. Because the full water weight lands near 1,668 pounds, the pad underneath does real work; our guide on concrete pad sizing for above-ground polyethylene tanks walks through getting that base right. Since this is an ASTM-built Snyder vertical, the freeboard and usable-volume discipline in our Snyder freeboard sizing per ASTM D1998 piece is worth a read before you finalize a level setpoint.
The mistake to avoid
The 1.9 specific gravity rating is the spec people misread. It does not mean the tank holds 1.9 times more; it means the wall is engineered for liquids up to 1.9 times the density of water. For water storage you have generous structural margin. The costly mistake is the reverse — buying a lighter-rated tank for a dense liquid. This 200-gallon vertical gives you that margin, and if you are sizing a fire-water reservoir or a reuse train, the discipline is covered in our guides on fire-water reservoir tank design and industrial water reuse tank topology. Fitting and outlet configuration for this tank is confirmed at order — call 866-418-1777 and we will match it to your plumbing before it ships.
Freight
This tank ships LTL freight from the Snyder plant in Merced, California, with the cost quoted live to your ZIP rather than baked into the list price. Because it originates on the West Coast, expect freight to weigh more heavily on Eastern deliveries, so get the real number before you commit. Our Freight Cost Estimator returns an exact figure in seconds, or call 866-418-1777 and we will quote it by phone. Give us the delivery ZIP and whether you need a liftgate or residential delivery, and we will get you a firm freight figure up front.
