The Chem-Tainer 62 Gallon PE Rectangular Open Top Tank is a compact, open-top polyethylene tank for batching, washdown, parts soaking, secondary capture, and general water storage where you need easy top access and a footprint that tucks into a corner. Built by Chem-Tainer in polyethylene, it holds 62 gallons. The open top lets you fill, dip, mix, and clean without working through a small lid, which is why it shows up so often when people search for an open top tank, a rectangular open top tank, or simply an open tank to drop into a fixed space.
Will it work for your job?
Start with weight, not just gallons. Filled with water, this tank carries roughly 517 lbs at full volume, so the stand, bench, or floor underneath it has to be rated for that load plus the empty tank. A rectangular open-top shape gives you a stable, flat-sided vessel that sits flush against walls and other tanks, which is useful when you are lining up multiple stations or fitting a tank into a defined bay. If you are not sure 62 gallons is the right capacity for your flow or batch size, run the numbers with our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. For sites where this tank feeds a larger storage or reuse system, our guide on industrial water reuse tank topology covers how grey-water, rainwater, and condensate streams get aggregated into quality-banded storage trains.
Set it on the right base, and plan your outlet
Open-top rectangular tanks need full, continuous support under the entire base. Water finds its own level, so any uneven spot, gap, or unsupported overhang turns into a stress point over time. A flat, level surface that supports the whole footprint is the goal. If this tank is going outdoors or onto a permanent above-ground pad, our concrete pad sizing framework walks through the ACI 360R-10 approach and where the ACI 318 boundary kicks in. One more thing to plan for: this SKU has no factory fittings or bulkhead ports listed, so any drain or outlet you need is a field modification you are responsible for installing and sealing. Outside dimensions are not yet published for this tank, so confirm the footprint before delivery.
The mistake to avoid
This is an open-top water tank with no sealed lid listed, which means it offers no vapor containment, no overfill protection, and no security for the contents. That is exactly right for attended hand mixing, dipping, and rinse work where open access is the whole point - and wrong for unattended outdoor storage or anything contaminant-sensitive, since the contents are exposed to evaporation, debris, splash-out, and whatever is airborne nearby. If you actually need a tank that drains clean to a low residual heel, an open-top rectangular tank is not the shape for it; our comparison of Chem-Tainer cone-bottom tanks at 30 vs 45 degrees shows the drainage difference. And if your application drifts toward storing anything other than water, confirm the material and specific-gravity requirements for that specific fluid before you put it into service rather than assuming a general-purpose open-top tank will cover it.
