The Chem-Tainer 15 Gallon PE Rectangular Open Top Tank is a compact polyethylene open-top vessel built for batching, mixing, parts washing, small-volume water storage, and any job where you need an open tank you can reach into. Listed at 15 gallons in a rectangular open-top format, it fills the role of a workbench-scale water container without the bulk of a round drum.
Will this tank work for your job?
This is a 15-gallon rectangular open top tank molded from polyethylene and classed for water-equivalent service at a specific gravity of about 1.0. Plan your support and handling around a full water weight of roughly 125 lb at 15 gallons of clear water (about 8.34 lb per gallon), so a sturdy shelf, cart, or bench will carry it easily once you account for that filled load. The open top gives you full access for hand-mixing, dipping, scooping, or dropping in a small pump or float, and the rectangular footprint sits flatter against a wall or inside a containment tray than a round tank of the same volume. This is a bare open-top vessel with no pre-installed fittings, so plan on over-the-top access or an external pump rather than a bulkhead outlet. If you are weighing this size against a larger reservoir, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Freight: how it ships
This tank ships LTL from the Chem-Tainer plant in Delano, MN, with freight quoted live to your ZIP code. Because it is an open-top, lightweight unit, palletizing and handling are straightforward, but the final number still depends on your delivery point and accessorial needs such as liftgate, residential, or limited-access delivery.

The mistake to avoid
The common error on a small open-top tank like this is treating it as a closed pressure or transport vessel. It is an open top tank, so it is not built to be sealed, pressurized, or moved while full, and an open surface means evaporation and contamination exposure for anything stored long-term. Just as important: this unit is rated for water-equivalent contents at roughly 1.0 specific gravity, so heavier chemistries that push past that need a tank rated for the higher specific gravity instead. Match your contents to that water-service rating, keep the filled load within whatever the tank sits on, and stage it where the open top is an advantage rather than a spill risk. For projects that grow beyond bench scale, our guides on concrete pad sizing for above-ground polyethylene tanks and industrial water reuse tank topology show how a small open tank fits into a larger storage train.
