The Norwesco 6502 Gallon Black Vertical Storage Tank is built for high-volume bulk water and liquid storage, where a single large vessel beats a tank farm of small ones. Molded from polyethylene in black, it carries a 1.5 specific gravity rating, stands 196 inches (16'-4") tall, and sits on a 102 x 102 inch (8'-6" square) footprint. Before anything else, verify two things at your site: 196-inch vertical clearance and 102 x 102 inch of level pad space. Those two numbers disqualify many locations, so self-qualify up front. This is a serious vertical column of storage for fire reserve, agricultural, and industrial water programs.
Will this tank work for your site?
This Norwesco vertical storage tank holds 6,502 gallons. At capacity with plain water, contents weigh 54,227 pounds; the 1.5 SG rating means the tank wall is engineered for liquids up to a maximum rated contents weight of 81,340 pounds, so it has genuine headroom for fluids denser than water. Rated to 1.5 specific gravity, this tank stores fluids up to roughly 50% denser than water - suitable for many process liquids and brines, subject to OEM chemical-compatibility confirmation for your specific chemistry. The 102 x 102 inch footprint and 196-inch height drive the install decision: a column of water this tall and heavy needs a level, full-contact foundation. Pour a pad rated for the full 81,340-pound loaded weight - the design number, not the 54,227-pound water figure - and run it against our concrete pad sizing guide before the tank arrives. Not sure this is the right capacity for your draw-down and refill cycle? The Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand.
Fittings and common applications
Fitting and manway configuration varies by unit, so call 866-418-1777 to confirm inlet, outlet, and manway sizes and locations before you plumb the tank or order accessories. Bulkhead fittings, gaskets, and manway hardware must match the as-molded port sizes on your specific tank - confirm those sizes before ordering, since the wrong gasket or fitting size is a slow leak waiting to happen. For rural and remote fire-protection reserves, a tank this size anchors the private water supply; our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. If you are aggregating grey-water, rainwater, or HVAC condensate into a reuse train, the industrial water reuse topology guide shows where a large vertical tank fits the stack, and our rainwater harvesting guide covers first-flush diverter sizing.
The mistake to avoid
The most expensive error on a tank this size is underbuilding the foundation or skipping the SG check. The 1.5 specific gravity rating is the wall's design limit, not a free pass - if your stored liquid is denser than 1.5 SG, this tank is not rated for it, and a heavier fluid in a tank built for lighter service is a structural failure waiting to happen. Verify your liquid's specific gravity against the 1.5 rating, and size the pad for the full 81,340-pound rated load, not just the 54,227 pounds of plain water.
Freight
This Norwesco vertical storage tank ships LTL freight from the Albertville, AL plant, quoted live to your ZIP code - freight is billed separately from the list price. Because of its height and footprint, this is an oversize LTL shipment; get an exact number with our Freight Cost Estimator or call 866-418-1777 and we will walk you through delivery, offload requirements, and lead time. One Source Plastics carries Norwesco vertical storage tanks, and we are here to make sure the tank, the pad, and the freight all line up before you commit.
