The Chem-Tainer 112 Gallon Rectangular Open Top Tank is a straight-sided, open-top polyethylene tank built for batching, mixing, washdown, and rectangular open tank storage where you need easy top access and a footprint that fits tight against a wall or inside a containment curb. Rated at 112 gallons, it fills a common water and process-storage need without the wasted floor space of a round tank.
Will it work for your setup?
This is a rectangular open top tank, so the entire top is accessible for hand-mixing, dipping, dosing, or dropping in a pump or agitator. It ships as a bare open-top polyethylene vessel with no pre-installed fittings, outlet, or drain, so plan to plumb from the top or add a bulkhead fitting to suit your process. Support it around a full load: at 112 gallons of water this tank carries roughly 934 pounds when full, so size your platform to the full water weight, not the empty tank. A flat, continuous, fully supported surface that will not flex or point-load the flat bottom is the right foundation for an open-top vessel of this weight. Because the top is open, factor in evaporation, debris, and splash if the tank sits outdoors or near traffic, and add a cover if your process needs one.
To match this 112-gallon size to your actual daily draw or batch volume, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a footprint. If you are aggregating water from more than one source, the industrial water reuse tank topology guide walks through how open storage fits into a staged storage train.
The pad matters more than you think
The most common mistake with a flat-bottom open-top tank is setting it on soil, gravel, or a pad that is smaller than the tank base. A flat polyethylene bottom transfers load evenly only when the surface underneath is flat and continuous; any gap, high spot, or unsupported edge concentrates stress and can crack or deform the bottom over time. Size the pad to the full base and keep it level. Our concrete pad sizing guide covers the ACI framework for getting the foundation right the first time.
