The Norwesco 6000 gallon black heavy-duty vertical storage tank is built in polyethylene for bulk water storage where a tall, small-footprint vessel is the goal. It stands 182 inches tall - over 15 feet - on a 102 x 102 inch (8.5-foot) square footprint, so treat overhead clearance and site access as a first-pass check item before you commit to a location. The tank carries a 1.9 specific gravity rating, which describes the maximum density of liquid the wall is structurally engineered to carry at full volume. If you have been searching Norwesco vertical storage tanks in this size class, this is the black version intended for outdoor water service.
Will this tank handle your liquid?
Start with weight, because at 6000 gallons the numbers drive everything downstream. Filled with plain water the contents alone weigh 50,040 pounds, and the 1.9 specific gravity rating means the wall is structurally rated to carry up to 95,076 pounds of liquid at maximum rated density. Before you finalize your plan, confirm your liquid's actual specific gravity against the 1.9 rating using the Tank Sizing Calculator, and review the Tank Sizing Guide to match height, footprint, and volume to your site. The black resin is a functional choice for stored water out in the open: it blocks light transmission through the wall, which limits algae growth far better than a translucent tank.
Foundation and site planning
A vessel this size demands a properly engineered base. At full water weight of 50,040 pounds plus the tank itself, the load on your pad is significant and must be supported across the entire 102 x 102 inch footprint with no voids or high spots. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that foundation right. If this tank is part of a rural or remote fire-water reservoir, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or condensate aggregation, see our guide on industrial water reuse tank topology.
The mistake to avoid
The single most common error on a tank this large is treating the 1.9 specific gravity rating as headroom you never need to check. The rating tells you the maximum density the wall is engineered to carry, not a guarantee for any liquid. Verify your liquid's specific gravity first; a fluid heavier than your assumption changes the real load on the wall and the base. Equally, do not undersize the foundation off a water-weight figure if your stored liquid pushes the load up toward that 95,076 pound rated maximum. Confirm both the liquid and the pad before the tank ships.
