The Chem-Tainer 200 Gallon Open Top Batch Storage Tank (SKU TC3648AB) is a cylindrical open-top vessel molded in natural white polypropylene, standing 48 inches tall on a 36 inch diameter (36 x 36 inch footprint). The open top makes it a working tank rather than a closed reservoir: you fill it by hand, mix or batch in it, read the level by eye, and reach inside to clean it. If you are searching for a 200 gallon open top tank in polypropylene, this is the size and shape that fits that brief.
Does it work for your application?
At a nominal 200 gallons, a full charge of plain water weighs about 1,668 pounds resting on the 36 inch diameter base, so size the slab and the surrounding space around that loaded weight rather than the empty shell. The 48 inch height keeps the rim within reach for filling and inspection without a ladder on most installs. Use the technical drawing on this page to confirm the wall geometry and overall dimensions before you commit floor space, and run your volume math through our Tank Sizing Calculator and Tank Sizing Guide if you are matching this tank to a daily batch or holding requirement. As an open-top batch and storage vessel, it also suits grey-water, rainwater, and condensate aggregation duty in a quality-banded reuse train, covered in our industrial water reuse tank topology guide.
The mistake to avoid
This is an open top batch and storage tank, not a sealed or pressure vessel. It holds liquid at atmosphere with the top accessible, so do not treat it as a closed system or expect it to seal against vapors. The capacity is nominal to the brim of the cylinder; leave freeboard rather than filling to the very top, especially if you are mixing or if the liquid will move. Note that no factory outlet or bulkhead fittings are listed for this tank, so an open-top vessel like this is typically drilled and fitted in the field. Specify fitting size, gasket material, and outlet location at the time of order by calling 866-418-1777, and confirm the open diameter and overall height against the technical drawing so the tank clears any cover, framing, or overhead you build around it.
Freight
This tank ships by LTL freight, quoted live to your ZIP code from the nearest stocking plant, with origins listed in Hanford, CA and Lincoln, NE. Because LTL pricing depends on distance, accessorials, and your delivery type, get an exact number for your address with our Freight Cost Estimator rather than estimating, and call us to confirm the true ship point before you commit so the quote reflects the real origin. For pad design under a loaded tank of this weight, our guide on concrete pad sizing for above-ground tanks walks through the framework. Questions on fit, freight, or lead time? Call 866-418-1777 and we will help you size it right.
