The Chem-Tainer 1150 Gallon Vertical Storage Tank (SKU TC8657IC-BLACK) is a black polyethylene vertical storage tank built for bulk water and general liquid storage where you need real capacity in a compact footprint. It stands 57 inches tall on an 86 x 86 inch base, so a full 1,150 gallons of water sits low and stable rather than towering. This is the black build of Chem-Tainer's vertical storage line, and the color is a functional choice for outdoor water service: black polyethylene blocks light transmission through the wall, which suppresses the algae growth that plagues natural and translucent tanks holding water in the sun.
Will it work for your site?
Start with weight, because that drives everything downstream. Filled with water, this tank carries roughly 9,591 pounds of contents. It's rated to a specific gravity of 1.5, meaning the walls are engineered for liquids up to 50 percent denser than water, and at that ceiling the contents can reach about 14,386 pounds. That headroom is why an SG-1.5 tank suits heavier-than-water fluids, but for plain water storage the number that matters is the roughly 9,591-pound full load resting on an 86 x 86 inch footprint. Your pad has to carry that concentrated point load, not just cover the ground area. If you're still deciding between sizes, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Foundation and placement
A tank this heavy needs a flat, fully supporting base under the entire bottom; above-ground poly tanks want a proper pad, not bare soil or partial support. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab matches the worst-case contents load, which can approach 14,386 pounds at the SG-1.5 rating. Verify the listed tank dimensions and footprint before you pour anything. If this feeds a rural or remote supply, our fire-water reservoir design guide and water-reuse tank topology guide cover how a vertical storage tank fits into a larger stored-water system.
The mistake to avoid
Don't buy on capacity alone. The most common error on a 1,150-gallon vertical tank is treating the SG-1.5 rating as a license to store anything: this build is sold here for water service, and any denser or chemically aggressive fluid needs its own compatibility check before you fill it. The second mistake is under-building the foundation. Design the pad to the two loads that are actually stated, roughly 9,591 pounds full of water and up to 14,386 pounds at the SG-1.5 maximum, rather than to the empty tank. If you're weighing this Chem-Tainer build against comparable Snyder or Norwesco verticals, our brand comparison lays out how the three lines differ.
