The Snyder Industries 290 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 290-gallon polyethylene vertical storage tank built to ASTM standards, and its defining spec is the 1.9 specific-gravity rating — a heavy-duty rating engineered for fluids denser than water. That number tells you exactly what this tank is engineered to hold, and it drives every sizing decision below.
Will this tank work for your job?
The tank stands 60 inches tall on a 42 x 42 inch footprint, so it fits a compact pad while still holding 290 gallons. In black polyethylene, the opaque wall of this black tank blocks light and discourages algae growth in stored water — one reason black vertical tanks are a common pick for outdoor and utility water service. Filled with plain water (specific gravity 1.0), the contents weigh roughly 2,419 pounds; because the tank carries a 1.9 SG rating, it is rated for a maximum contents weight of about 4,595 pounds, giving real headroom for denser fluids without pushing the wall beyond its design. Use the technical drawing on this page to confirm fitting locations and the pad footprint before you set it, and run your volume through the Tank Sizing Calculator or the Tank Sizing Guide if you are still narrowing capacity.
The one number that decides your pad and your fill
That 1.9 SG rating is the spec buyers most often overlook. It means the wall is engineered for the weight of fluids up to 1.9 times the density of water — but it does not mean you can ignore what you actually store. The design envelope runs from about 2,419 pounds at water (SG 1.0) to roughly 4,595 pounds at the full 1.9 rating, so size your pad for 4,595 pounds regardless of what you plan to fill it with. At 42 x 42 inches of footprint carrying that load, the ground under the tank has to be flat, fully supporting, and rated for the mass — a partial or crowned pad is the most common install mistake with a heavy-duty vertical tank. See Concrete Pad Sizing for Above-Ground Polyethylene Tanks for the ACI framework, and the Snyder Captor freeboard guide for how ASTM D1998 shapes the volume you can actually use.
