The Chem-Tainer 575 gallon open top batch storage tank is a cylindrical, top-loading vessel built for water and aqueous batch work where you need quick access from above - mixing, settling, dosing, or staging before the next process step. It stands 46 inches tall on a 60 by 60 inch footprint, holds 575 gallons of usable volume, and is molded from natural white polyethylene so you can read the liquid level through the wall. If you are searching for an open top tank or white open top storage tank that takes up little vertical room while giving you a wide working diameter, this is the size that fits a low-ceiling room or a pump pad where overhead clearance is tight.
Will it work for your job
Plan around two weights, not one. Filled with plain water at a specific gravity of 1.0, this tank carries roughly 4,796 pounds of liquid on its footprint. Because the shell is rated to a specific gravity of 1.9, the maximum rated contents weight climbs to about 9,111 pounds when you fill it to that rating - that is the number your pad, floor, or stand has to support. That 1.9 rating is also headroom you can buy on purpose: the same shell handles denser aqueous batch chemistry - heavier brines and solutions up to SG 1.9 - without stepping you into a different tank, and the 9,111 pound figure is the proof of that capacity. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you pour concrete so the base is sized to the loaded weight, not the empty tank. The 60 by 60 inch footprint spreads that load over a 25 square foot area, which keeps point loading down on a properly prepared pad.
Mounting and the open top format
An open top means no closed lid casting in the way - you load, sample, skim, and clean from above, and you can drop in a mixer or fill line without cutting a sealed top. The flat-bottom cylindrical shape sits directly on a level, fully supporting surface; it is not a stand-mounted cone tank, so it wants continuous contact underneath across the full 60 inch diameter. One thing to settle up front: a flat bottom does not self-drain the way a cone does, so if you are settling solids and care about residual heel and cleanout, read our comparison of Chem-Tainer cone-bottom tanks at 30 vs 45 degrees before you commit to a flat-bottom batch tank. The natural white wall doubles as a sight gauge for batch-to-batch level checks. See the technical drawing on this page for the molded dimensions and wall detail before you set anchor points or size a containment curb.
Freight - how this tank ships
This is an LTL freight item, and the freight math works in your favor on either coast. Chem-Tainer molds this tank at multiple plants, and the two nearest you here are Hanford, CA for the West and Hummelstown, PA for the East; we ship from whichever named plant is closest to your delivery ZIP, which shortens the LTL lane and directly lowers your live quote. Freight is quoted live to your ZIP rather than baked into the list price - get your number from the Freight Cost Estimator or call us at 866-418-1777 and we will price it with you.
One thing not to get wrong
Size the foundation to the loaded weight, not the catalog gallons. The same 575 gallon shell can put under 4,800 pounds or over 9,100 pounds on your base depending on what you fill it with, so confirm your contents' specific gravity first and build the pad to the heavier case. If you are designing the slab itself, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework. Putting reused process or rainwater into this tank? The industrial water reuse tank topology guide covers quality-banded storage trains, and if you are staging fire-water at a rural or remote site, our fire-water reservoir tank design guide covers NFPA 22 sizing for an open-top vessel like this one.
