The Snyder Industries 290 Gallon Black Heavy Duty Vertical Storage Tank is a 72-inch-tall polyethylene vertical storage tank on a compact 36 x 36 inch footprint, built for bulk water and liquid storage where floor space is tight but capacity needs to stay high. Molded in black to block light and slow algae growth in outdoor and partially lit installations, it carries a 1.9 specific gravity rating, which is the spec that tells you how heavy a liquid this tank is engineered to hold. Whether you are sizing a fire-water reservoir, a rainwater catchment leg, or a process-water buffer, the numbers below let you confirm fit, pad, and freight before you commit.
Will this tank work for your job
The tank holds 290 gallons of working capacity at 72 inches tall on a 36 x 36 inch footprint, so it slides into corners, equipment rooms, and trailer beds that wider tanks cannot. Filled with plain water at roughly 8.34 pounds per gallon, expect about 2,419 pounds of full water weight bearing on the base. The "Heavy Duty" designation is not marketing here: it is the 1.9 specific gravity rating, which backs a maximum rated contents weight of 4,595 pounds. That is what separates this tank from a standard 1.0 to 1.5 SG water tank and lets it hold denser-than-water liquids such as brines, fertilizers, and many acid solutions up to the 1.9 SG ceiling. The base sits on a 36.0 x 36.0 inch footprint, so plan your pad and any restraint to that square plus clearance for fill and outlet plumbing. Use the Tank Sizing Calculator and Tank Sizing Guide to match this 290-gallon vertical storage tank to your actual draw and refill cycle.
Fittings and outlet configuration
Fitting and outlet placement on this vertical storage tank is not assumed by default, so do not plan plumbing around a bottom outlet until it is confirmed. Refer to the technical drawing on this page for fitting locations and overall dimensions, or call 866-418-1777 and we will verify the exact outlet and bulkhead configuration before you order. That single check prevents the most common post-delivery complaint on a tall vertical tank.
The mistake to avoid
The big error on a black vertical tank like this is treating the specific gravity rating as a suggestion. The 1.9 SG number means the wall is built to support a contents weight up to 4,595 pounds; if you store a liquid heavier than 1.9 SG, you are over the tank's design. For plain water service you have wide margin, but always check your liquid's specific gravity against the 1.9 rating first. For denser or chemical service, the tank rating covers weight, not chemical attack: verify the polyethylene wall and any gasket or fitting elastomer (EPDM versus Viton, for example) against your stored liquid before ordering. The second mistake is the pad: at 2,419 pounds of water alone, this tank needs full, continuous, level support under the entire 36 x 36 inch base, not a partial or sloped surface. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the support framework, and for cold-climate fire-water duty the fire-water reservoir tank design guide covers freeze protection and NFPA 22 sizing discipline. For any regulated or denser liquid where a single-wall tank alone is not enough, the Snyder Captor double-wall freeboard sizing guide covers secondary containment and usable-volume planning.
Freight and ordering
This Snyder vertical storage tank ships LTL freight from the Philippi, West Virginia plant, quoted live to your ZIP code. Because freight on a 72-inch tank is rated by size and distance rather than weight alone, get an exact number before you order using our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. List price shown here is the tank before freight. If you are aggregating water from multiple sources or banking grey-water and rainwater, the industrial water reuse tank topology guide helps you stage storage trains around a black vertical tank like this one.
