Chem-Tainer 250 Gallon Vertical Storage Tank

The Chem-Tainer 250 Gallon Vertical Storage Tank (SKU TC3184IC-NAT) is a natural white polyethylene vertical tank built for straightforward bulk water storage when you need real capacity in a small footprint. It stands 84 inches tall on a compact 31 x 31 inch base — about a 2.7 square foot footprint, roughly half a standard 48 x 40 pallet — so you get a full 250-gallon reserve while giving up very little floor space. That tall vertical build makes it a practical choice for a water storage tank in tight rooms, along walls, or on pads where a squat tank would not fit, and it handles water hauling, rainwater collection, irrigation supply, and general on-site storage.

Will this 250 gallon tank work for your setup?

Filled with water, this tank carries about 2,085 pounds, so the pad, floor, or platform underneath has to be flat, level, and rated to hold that load fully supported across the entire base. The tank is molded to a 1.5 specific gravity rating, which means it is engineered to hold contents up to a 1.5 SG density — a maximum rated contents weight near 3,128 pounds — without stressing the wall. For plain water at 1.0 SG that gives you comfortable headroom, and the same 1.5 SG wall means this vertical storage tank is rated for fluids denser than water, up to that 1.5 limit, if your application calls for it. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 250 gallon size matches your daily draw and refill cycle before you commit.

Foundation, venting, and installation

Because a tall, narrow vertical tank sits on a small 31 x 31 inch footprint, foundation prep matters more than it does on a squat tank. A continuous, level concrete pad is the safest support for a filled vertical tank of this height. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework so your base carries the full water weight evenly. Make sure the tank is properly vented as well — a sealed poly tank can pull a vacuum and collapse on a fast, high-rate draw, or balloon under a fast fill, so an adequate vent sized to your fill and draw rate is not optional. Fittings on this tank are configured to order, so call 866-418-1777 to spec your fill, vent, and outlet openings, and refer to the technical drawing on this page for dimensional detail before you set anchors or plumb any lines.

How it ships

This is a water-service tank, and it ships LTL freight from the Chem-Tainer plant in Hanford, California, with freight quoted live to your ZIP code rather than bundled into the list price. Because it is a large vertical tank shipping from the West Coast, buyers farther east should set freight expectations accordingly and plan for common-carrier delivery on a pallet with offload at your site.
