The Snyder Industries 6000 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a full-scale black vertical storage tank molded from heavy-duty polyethylene and rated to a 1.9 specific gravity, which is what earns the "heavy duty" designation. Rated at 6,000 gallons, it stands 188 inches tall on a 102 by 102 inch footprint — an 8.5-foot square pad — so plan your slab and overhead clearance around those numbers before you order. The black exterior blocks light to slow algae growth, making this black water storage tank a workhorse for exterior bulk holding, fire-water reservoirs, and industrial vertical storage.
Will it work for your site?
The 1.9 specific gravity rating is the headline spec: this tank is built to hold contents up to 1.9 SG, well above the 1.0 density of water. Filled with water, it carries about 50,040 pounds; at its maximum rated contents weight it bears roughly 95,076 pounds. Those loads dictate a properly engineered foundation — use our concrete pad sizing guide to size the slab, and the Tank Sizing Calculator and Tank Sizing Guide to confirm the capacity matches your draw and refill cycle. Per the technical drawing on this page, the tank is outfitted with a flange, an 18-inch polyethylene threaded/vented fitting, a manway with 15-inch access, and two 12 by 23 inch fittings (one flat) — your top-side connections for fill, vent, and inspection. Gaskets and bulkhead fitting kits are quoted separately; call 866-418-1777 to spec them rather than assuming the ports ship sealed.
Fire-water and reservoir duty
At 6,000 gallons this is a common size for private fire-protection storage and rural reservoir builds. For that application, our fire-water reservoir tank design guide walks through NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse tank topology guide covers quality-banded storage trains and treatment sequencing.
The mistake to avoid
Don't under-build the foundation. The temptation on a big vertical is to treat the full-water number as the design load, but with a 1.9 SG rating this tank can legitimately hold contents nearly double the water weight. Size the pad and any anchoring to the service you actually intend to run, not just to water, and confirm overhead clearance for the 188-inch height plus the vent and fill fittings before the truck arrives. At 1.9 SG this is the top of Snyder's heavy-duty ladder in this class, so there's no heavier-rated 6,000-gallon poly vertical to shop up to.
