The Snyder Industries 6200 Gallon ASTM Black Vertical Storage Tank is a bulk polyethylene storage tank built for high-volume water and dense-liquid service. It holds a nominal 6,200 gallons in a 120-inch diameter by 140-inch tall vertical body, giving you a 120.0 x 120.0-inch footprint to plan your pad around. The tank carries a 1.5 specific-gravity rating, so it is engineered to hold contents heavier than water without derating the shell.
Will it work for your site
Full of water this vertical storage tank weighs about 51,708 pounds, and at its maximum 1.5 SG rating it can carry roughly 77,562 pounds of contents. Those loaded weights drive every foundation and siting decision, so confirm your pad and subgrade can carry them before delivery. Standing 140 inches (about 11 feet 8 inches) tall before you add fill and vent hardware on top, so verify overhead clearance and room to reach the manway when you locate the tank. The black exterior blocks light to slow algae growth in water service; be aware that black also absorbs solar heat and can raise contents temperature in open outdoor placement, which matters if you are also managing freeze cycles. Plumbing and access come through a flanged outlet, eight flat fitting pads placed at 45 degrees around the body, and an 18-inch PE threaded manway for entry, fill, and inspection. The flat pads ship as blank bosses, not pre-drilled ports, so you add bulkhead or flanged fittings at the elevation you need. See the technical drawing on this page for the exact fitting locations and elevations, and use our Tank Sizing Calculator and Tank Sizing Guide to match capacity and freeboard to your draw-down needs.
Sizing the pad and the load
A vertical tank of this scale lives or dies on its foundation. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework and where the ACI 318 boundary applies, and the Snyder freeboard sizing per ASTM D1998 piece explains why the real usable volume sits below the nameplate. If this is fire-water or reserve storage, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For reuse trains blending grey-water, rainwater, or HVAC condensate, see our industrial water reuse tank topology guide.
The mistake to avoid
The common error on a black tank this size is treating the 1.5 SG rating as license to skip the load math. The 1.5 rating tells you the shell can handle a dense liquid, but your pad, anchoring, and any structure underneath still have to carry the full loaded weight for the contents you actually store. Run the max-rated 77,562-pound figure through your foundation design, not just the water weight. Remember that 1.5 is the ceiling: if your fluid exceeds specific gravity 1.5, this shell is not rated for it. And when you tie into the flanged outlet or any bolted connection, confirm the gasket material is right for your fluid before the tank goes into service.
