The Chem-Tainer 300 gallon vertical water storage tank (SKU TC4560IW-NATURAL) is a single-wall, white polyethylene tank built for straightforward bulk water storage. It stands 60 inches tall on a 45 x 45 inch footprint, holds 300 gallons, and weighs roughly 2,502 pounds full of water. The shell is molded in FDA-approved polyethylene and rated to a 1.0 specific gravity - which makes it a clean fit for potable and water-contact storage such as drinking-water staging, hauled potable, and reserve supply, while keeping it squarely within the FDA-approved fact and a water-density application.
Will this 300 gallon tank work for your job?
For a vertical water storage tank in this class, the two numbers that decide the install are the footprint and the loaded weight. The base is 45 x 45 inches - about 14 square feet - and a full tank at roughly 2,502 pounds puts about 178 pounds per square foot on whatever it sits on. Plan a level pad or stand rated for at least that bearing load, fully supporting the entire base, before you fill. The 60-inch height keeps the center of gravity reasonable for a 300 gallon vertical, but a heavy tank on a partial or uneven foundation is the fastest way to a failure. If you are weighing this capacity against your actual demand, run the figures through our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a size.
The mistake to avoid: specific gravity
The most common error on a tank like this is putting a heavier-than-water liquid into a 1.0-rated shell. This Chem-Tainer is a water storage tank, and the rating reflects exactly that - water and contents no heavier than water. Storing anything denser (chemicals, brine, or fertilizer above 1.0 specific gravity) is outside what this shell is rated to carry. If that is your application, call 866-418-1777 and we will point you to a tank rated for your density rather than risk this one. For sizing context across this class, the 300 gallon vertical buyer's guide and the Snyder vs Norwesco vs Chem-Tainer vertical comparison walk through the trade-offs.
Fittings and water-handling applications
This 300 gallon vertical fits the standard run of water storage work - water holding, gravity-feed supply, hauled-water staging, and reserve capacity. One thing to confirm before you order: no bulkhead fittings, gaskets, or outlets are specified in this listing, so verify outlet size, thread type, and gasket material against the technical drawing on this page or by phone - do not assume a fitting is included. For heavier-duty planning context, see our guide on fire-water reservoir design for rural sites and on water reuse storage architecture for grey-water, rainwater, and condensate aggregation.
This water storage tank ships LTL freight from a single Chem-Tainer plant in Marked Tree, AR, so the cost is distance-driven - pull your exact ZIP number before you commit.
