The Chem-Tainer 94 Gallon PE Rectangular Open Top Tank is a polyethylene rectangular open-top vessel for water storage, batching, and washdown work where you need direct top access for filling, dipping, or manual additions. It ships LTL freight from West Babylon, New York, quoted live to your ZIP, so know your shipping origin before you plan a stand. With a 94-gallon working capacity and an open top, it suits short-term holding, mixing, and transfer staging in agricultural, municipal, and light-industrial settings. If you have searched for an open top tank, a rectangular open top tank, or a straightforward open tank for a tight footprint, this is the rectangular tank that fits flat against a wall or inside a containment curb.
Will it work for your job
This is a 94-gallon polyethylene open-top rectangular tank. Filled to capacity with water it carries about 784 pounds, so plan the stand or pad for that load plus the empty tank weight. The rectangular shape uses floor space efficiently, and the open top gives you direct access for adding product, cleaning out, or dropping in a pump or mixer. To size it against your actual draw or batch volume, run the numbers with our Tank Sizing Calculator and check the Tank Sizing Guide. Dimensions are shown on the technical drawing on this page; review it before you order so the footprint matches your layout. This is an open-top tank with no factory outlet fitting in our data, so if you need a drain or bulkhead, confirm placement against the drawing first or call us to spec a fitting.
Mounting and water-storage notes
Because the full-water weight is roughly 784 pounds, this tank needs continuous, level support across its entire base, not just the corners. Open-top tanks are vented, atmospheric vessels, so keep them for water and aqueous service at ambient pressure. If you are setting it on a concrete pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for sizing the slab. For rainwater capture, grey-water staging, or HVAC condensate aggregation, the industrial water reuse tank topology guide shows how open-top staging tanks fit into a larger reuse train, and if this feeds a private fire-protection setup, the fire-water reservoir tank design guide covers NFPA-22 sizing discipline.
The mistake to avoid
The common error with an open-top rectangular tank is treating it like a sealed or transport vessel. It is an atmospheric, vented water tank, so do not pressurize it, do not seal the top for transport, and do not site it where the weight is unsupported at the corners. If your liquid is heavier than water or you are unsure of its weight, confirm the load with the Tank Sizing Calculator or call before you order rather than assuming the water figure applies. Support the full base, keep it vented, and let the open top do what it is built for.
