The Chem-Tainer 1500 Gallon Open Top Batch Storage Tank (SKU TC7384AA) is a cylindrical open-top polyethylene tank for batch mixing, settling, and bulk water storage where overhead access matters. It stands 84 inches tall on a near-square 73 x 73 inch footprint - a relatively squat, low-and-wide stance - holds 1,500 gallons of natural white polyethylene, and is rated to a 2.0 specific gravity, which is what sets it apart from the standard open-top storage tanks rated near 1.5 and lower.
Will this open top tank work for your job?
Rated to 2.0 specific gravity, this tank is sized for contents up to twice the weight of water - rated for up to 25,020 pounds of contents, not just light water duty. That is the reason buyers reach for this open top over a lighter tank: the rating covers dense slurries, settling solids, and high-density batches, not only volume. The open top gives you full top access for adding material by hand, lowering in a mixer or agitator, manual sampling, or skimming, which is why it shows up in searches for an open top tank, a white open top tank, and general open tank storage. For matching this 1,500 gallon size to your actual fill volume and refresh rate, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Footprint and loaded weights for your pad contractor
Hand these three numbers to whoever pours your pad: empty footprint 73 x 73 inches, water-full weight 12,510 pounds, and maximum rated weight 25,020 pounds at the full 2.0 specific gravity. Because an open top tank has no top to help distribute load and is filled and worked from above, the pad and the surround matter more than on a closed vertical - the loaded weight lands on that 73 x 73 inch base. A level, properly sized concrete pad is not optional; review our guide on concrete pad sizing for above-ground polyethylene tanks before you pour. If this tank is part of a stored-water or reuse system, the industrial water reuse tank topology guide covers how open and closed tanks combine in quality-banded storage trains, and the fire-water reservoir design guide is the right read if this is feeding a private fire-protection or rural water supply.
No hardware included, and the mistake to avoid
This is a bare open-top tank: no fittings, outlets, bulkhead fittings, gaskets, agitator mount, or cover are included or listed. Specify and source any of that hardware separately, and confirm fit against the open rim before you order. The common error on a high-SG open top is treating the 2.0 specific gravity rating as a number to casually fill against without sizing the pad and supports for it. The rating means the tank can hold contents up to twice the density of water - but that loaded weight, up to 25,020 pounds, has to go somewhere, and an undersized or unlevel base is where these installs fail. Match the pad to the rated load, keep the rim true so any cover or agitator you add seats correctly, and confirm the open-top configuration is right for your process before adding material by hand or machine. If you are venting a separate, adjacent closed vertical alongside this batch tank, the atmospheric vent capacity guide works through API 2000 sizing for 1,500-gallon and larger tanks; note that open-top venting does not apply to this tank itself.
