The Chem-Tainer 250 Gallon Plastic Vertical Liquid Storage Tank (SKU TC3568IC) is a 68-inch-tall polyethylene vertical tank on a 35 x 35 inch square footprint, built to hold real capacity without spreading across a large floor area. It holds 250 gallons, and its narrow square base makes it a practical fit for pump houses, equipment sheds, well rooms, and the tight corners of a barn or shop. If you are weighing this size against alternatives, our 250 gallon vertical liquid storage tank buyer's guide walks through the trade-offs in detail.
Will it work for your liquid?
This is a vertical storage tank molded from polyethylene with a 1.5 specific gravity rating, meaning it is built to carry contents up to 1.5 times the weight of water. For plain water at 250 gallons, plan on roughly 2,085 pounds of contents when full; at the tank's full 1.5 SG rating, contents can reach about 3,128 pounds. That headroom is what lets the same tank handle heavier-than-water liquids, but you should always match the actual specific gravity of your liquid to the 1.5 rating before filling. The standing footprint is 35.0 x 35.0 inches and the tank stands 68 inches tall, so confirm your pad or platform is level and sized for both the loaded weight and the height. See the technical drawing on this page for fitting locations and overall dimensions, and use our Tank Sizing Calculator or Tank Sizing Guide if you are still settling on a 250 gallon size versus a larger vertical tank. Fitting sizes and locations are not published in our spec data for this SKU, so confirm the outlet or bulkhead fitting size and gasket material against your plumbing before ordering.

One mistake to avoid
The most common error with a 1.5 SG tank is assuming the rating alone makes it right for any liquid. The specific gravity rating tells you how much weight the wall structure is designed to carry, not whether the polyethylene resin is suited to a given fluid. For water and water-like contents this tank is straightforward; at 1.5 SG it already carries up to about 3,128 pounds of contents, well above water. If your liquid runs heavier than 1.5 SG, ask us about a heavier-wall version of this size before you order, and verify both the specific gravity and the material compatibility first. The other thing buyers overlook is the concentrated load: loaded to its 1.5 SG rating, this tank puts up to roughly 3,128 pounds on a 35 x 35 inch base, so verify your slab or stand is rated for that point load, not just level. Sizing a square-base 35-inch vertical tank into a fixed opening also catches people out, so measure your doorway and clearance against the 35 x 35 footprint and 68-inch height before delivery day.
Freight and how to order
This tank ships LTL freight, quoted live to your ZIP code rather than bundled into the list price. It stocks at Chem-Tainer's Bensenville, IL and Hummelstown, PA plants, and we route from whichever serves your ZIP at the lowest LTL cost. Run your ZIP through our Freight Cost Estimator to see your freight cost before you buy, or call 866-418-1777 and we will quote it for you and confirm the right vertical storage tank for your application.
