The Chem-Tainer 1150 Gallon Plastic Vertical Liquid Storage Tank is a 1,150-gallon polyethylene vertical tank standing 156 inches tall on a 48 x 48 inch footprint. If you are sizing a vertical storage tank for bulk water, fire-water reserve, or general liquid storage and need a tall, compact column rather than a sprawling horizontal tank, this is the size and shape that fits the question. Listed specifications below come straight from the manufacturer data.
Will it work for your liquid?
This vertical tank is rated to a specific gravity of 1.5, which means the polyethylene wall is built to carry contents up to 1.5 times the density of water. Full of water, the tank holds roughly 9,591 pounds; loaded to its full 1.5 SG rating, the contents can reach about 14,386 pounds. For a water or general-liquid buyer, that 1.5 rating is headroom, not a limit: it means the tank carries denser liquids without de-rating, so if you plan to switch service later you are not boxed in by the wall thickness. Those two weight numbers also drive everything underneath the tank: the pad, the soil bearing, and any anchoring you plan. Use the Tank Sizing Calculator to confirm the volume matches your draw-down needs, and read the Tank Sizing Guide if you are deciding between this vertical column and a wider, shorter tank for the same gallons. One note on plumbing: the inlet, outlet, lid, and gasket configuration is not listed in the published data for this tank, so confirm those sizes and the gasket spec by phone at 866-418-1777 before you order rather than assuming a fitting size.
The mistake to avoid: plan the pad and the clearance before the plumbing
At 156 inches tall and only 48 inches across, this is a tall, narrow column carrying up to 14,386 pounds when fully loaded to its SG rating. The most common and most expensive mistake is treating the foundation as an afterthought. A 48 x 48 inch footprint concentrates that weight, so the pad has to be flat, level, and engineered for the load. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks so the slab actually supports a fully loaded tank rather than cracking under it. The second check is clearance: 156 inches is 13 feet, and many buildings, roll-up doors, and access paths will not clear a 13-foot column, so verify overhead height and the route to the pad before the truck arrives to avoid a refused delivery. If this tank is feeding a rural or remote fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites. You can also reference the technical drawing on this page for the dimensional layout.
How it compares and where it fits
Chem-Tainer builds this in the same vertical storage tank family that buyers cross-shop against other brands. To see how Chem-Tainer compares to Snyder and Norwesco (illustrated at the 2,000-gallon size), the Snyder vs Norwesco vs Chem-Tainer comparison lays out the differences between the makers even though the numbers there are for a larger tank. For sites running grey-water, rainwater, or HVAC condensate into banded storage, the industrial water reuse tank topology guide shows where a vertical bulk storage tank like this slots into a treatment train.
This tank ships LTL freight from the nearest Chem-Tainer plant, either Hanford, CA or Marked Tree, AR, with the carrier dispatched to your delivery point. Because there are two plants, freight is quoted from whichever one is closer, which materially changes the LTL cost east versus west, so run your exact ZIP through the Freight Cost Estimator to see the real number from the nearer origin. Freight is quoted live to your ZIP and is never bundled into the listed price. For an exact figure or to confirm fitting sizes, call 866-418-1777 and we will quote it for you.
