The Snyder Industries 6900 Gallon Black Vertical Storage Tank is built for serious bulk water storage, holding 6,900 gallons in a 120-inch diameter, 153-inch tall polyethylene body. With a 10-foot footprint and just over 12.5 feet of height, it consolidates a large vertical tank reservoir into a single column - the practical answer when you need volume but not a sprawling tank farm. The black exterior limits light penetration, which helps suppress algae growth in stored water compared to lighter colors.
Will this tank work for your application?
This vertical storage tank is rated to a 1.5 specific gravity, meaning the wall is engineered to carry contents up to 1.5 times the weight of water. Filled with water alone it carries roughly 57,546 pounds of contents; at its maximum rated 1.5 SG loading it is built to hold up to 86,319 pounds. That is nearly 50% more load than plain water requires - real structural margin for heavier service or a long service life on water. Those numbers drive everything underneath the tank. A storage tank this size needs a properly engineered, level foundation - work through our concrete pad sizing guide (built on the ACI 360R-10 framework) before the tank ever arrives. The 120 x 120-inch footprint is your minimum pad dimension, and across that 100 square feet the base sees roughly 575 lb/sq ft at full water and about 860 lb/sq ft at the rated 1.5 SG load - the bearing-pressure number the pad designer actually sizes to.
Sizing it right for the job
If you are matching this 6,900-gallon black tank to a demand profile rather than buying on volume alone, run the math first. Our Tank Sizing Calculator and the companion Tank Sizing Guide help you back into the right capacity from drawdown, refill rate, and reserve. For rural and remote fire-protection reservoirs, the fire-water reservoir design guide walks through NFPA 22 sizing discipline and cold-climate freeze protection - relevant if this black storage tank feeds a private fire stack. For grey-water, rainwater, or HVAC condensate aggregation, see our industrial water reuse tank topology guide. The inlet, outlet, and lid configuration is specified on the technical drawing on this page and confirmed at order, so verify fitting placement against that drawing before you set the tank - plumbing a 12.5-foot column after it is full is not an option.
The mistake to avoid
The single most expensive error on a tank this size is underbuilding the foundation. At full water weight this vertical tank exerts well over 57,000 pounds on its base, and the rated load at 1.5 SG climbs past 86,000 pounds - so a pad that is undersized, unlevel, or not fully cured will deform the tank floor and void any expectation of service life. Treat the foundation as the first part you order, not the last. Verify the 120-inch diameter, the 153-inch height, and the inlet/outlet locations against the technical drawing on this page so the pad and the surrounding plumbing are dead-on before delivery day.
