The Chem-Tainer 500 Gallon Vertical Storage Tank (SKU TC6446IC-NAT) is a 500-gallon polyethylene vertical tank built for bulk water and general storage. It stands 46 inches tall on a 64-by-64-inch footprint, so it holds a full 500 gallons without a tall profile - a practical fit where overhead clearance is tight but floor space is available. The tank is molded in natural white polyethylene and carries a 1.5 specific gravity rating.
Will this 500 gallon tank work for your site?
Filled with water, this vertical storage tank carries roughly 4,170 pounds of contents, and its 1.5 specific gravity rating allows a maximum rated contents weight of about 6,255 pounds at full-height fill. That headroom is why the 1.5 SG rating matters: it tells you the wall is built to hold liquids heavier than water up to that weight ceiling - it does not mean any given fluid is chemically compatible. Because the full load runs into thousands of pounds, the pad underneath does real structural work. Confirm your slab before delivery with our Tank Sizing Calculator and Tank Sizing Guide, and if you are pouring new, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework a 6,255-pound rated load calls for. A 64-inch diameter on a 46-inch height is a deliberately squat vertical profile, so check the height and outlet placement against the technical drawing on this page before you set your plumbing.
The mistake to avoid
The common error on a natural-white vertical storage tank like this one is reading the 1.5 SG rating as a green light for any fluid. It is not. That rating governs weight, not chemical resistance, and it assumes a full-height fill - a heavier or reactive liquid still needs its resin and gasket compatibility confirmed against the manufacturer's chemical-resistance chart before you fill. For straight water storage, agricultural supply, fire-water reservoir duty, or rainwater and reuse service, this tank does the job as-is. Verify your outlet and fitting requirements against the technical drawing on this page before ordering, since the gasket elastomer - not the polyethylene wall - is usually the first thing to check on any liquid heavier than water.
