The Chem-Tainer 2150 gallon vertical liquid storage tank is a heavy-duty polyethylene bulk vessel built for serious water and high-density liquid storage. With a 1.5 specific gravity rating, it carries denser contents than a standard 1.0-rated water tank, which is what separates it from lighter-duty vertical tanks in the same capacity class. If you are sizing a vertical storage tank for fire-water reserve, agricultural water, process water, or industrial reuse, this is a tank engineered to hold a tall column of liquid without flexing past its rating.
Will it work for your site?
The tank holds a nominal 2150 gallons in a vertical footprint of 86 inches by 86 inches and stands 99 inches tall. That tall, relatively narrow profile is the classic vertical-tank trade-off: it stores a large volume on a compact pad, but the liquid column is heavy and the load concentrates on the base. Full of water this tank weighs roughly 17,931 pounds, and at its maximum rated 1.5 specific gravity it can reach about 26,896 pounds of contents. Those are the numbers that drive your pad design and your forklift or crane plan, not the empty shipping weight. Note too that at 99 inches the top lid and manway sit close to 8.25 feet off the pad, so filling, gauging, and lid access will need ladder or platform planning for the same crew handling the pad and rigging. Confirm the loaded footprint and access height against your site before you order.
Specific gravity is the spec that matters here
The single most common mistake on a tank this size is treating the 1.5 SG rating as a license to store anything. Specific gravity tells you the maximum density of liquid the tank wall is built to support at full height; it does not certify chemical compatibility. Water sits at 1.0, so this tank carries water with a comfortable safety margin. Match your liquid's actual specific gravity to the 1.5 number before you commit. If your contents run heavier than 1.5, this tank is not rated for the job and you should use our Tank Sizing Calculator or call 866-418-1777 so we can match a tank to a contents specific gravity above 1.5. The Tank Sizing Guide walks through capacity, footprint, and weight planning for vertical storage tanks like this one. Keep in mind that the SG rating covers wall structural load only; gasket and fitting material compatibility with your specific liquid is a separate check.
Fittings, pad, and placement
Fitting and gasket configuration for this tank, including bulkhead and outlet size, outlet location, vent, and lid or manway, is not specified in the listing data, so confirm it by phone at 866-418-1777 before finalizing your plumbing and pad design. A 2150 gallon vertical tank pushes meaningful load into its base, so it belongs on an engineered, level pad sized for the full loaded weight. Our guide on concrete pad sizing for above-ground polyethylene tanks covers the framework. If this tank is going into a fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, where a tall water column stresses the lowest fittings and gaskets first. For reuse and aggregation projects, see our industrial water reuse tank topology guide, and if you are weighing brands at this size, the Snyder vs Norwesco vs Chem-Tainer 2000 gallon comparison puts the options side by side. See the technical drawing on this page for the dimensional layout.
