The Chem-Tainer 500 Gallon Vertical Storage Tank (SKU TC6353IC-NAT) is a Natural White polyethylene vertical tank built for water and general liquid storage where you need real capacity on a compact footprint. It sits on a 63-inch diameter base and holds 500 gallons - the workhorse 500 gallon vertical storage tank buyers reach for on rural fire-water reserves, non-potable water holding, rainwater aggregation, and process water storage.
Will it work for your site?
Confirm two things before you order: fit and load. The tank occupies a 63 by 63 inch bounding footprint (63-inch diameter), so plan your pad and clearance around that, and check the exact height against the technical drawing on this page rather than eyeballing it. If you are matching this tank to a required volume, the Tank Sizing Calculator and Tank Sizing Guide take the guesswork out. Filled with water the contents weigh about 4,170 pounds. This shell carries a 1.5 specific gravity rating, so it is engineered for a maximum rated contents weight of roughly 6,255 pounds - which means for straight water you are sitting at about 67% of the rated load. That built-in structural margin is why the 1.5 SG shell is a sound pick even for plain water service: you are never near the tank's limit.
Foundation and support
A vertical tank this size needs a flat, fully supporting base sized to the complete footprint. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab carries the loaded weight without edge loading or point stress. If this tank anchors a private fire-protection reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
Do not under-build the base or set this tank on uneven ground. A 500 gallon vertical tank concentrates its load on a small footprint, and a poly tank is only as sound as what it sits on - a partial or unlevel pad is the most common failure at this size. Before you buy any bulkhead or hardware, verify the fitting and outlet layout against the technical drawing on this page; if you want a second set of eyes, call us and we will confirm the outlet size and supply the matching bulkhead fitting and gasket so your inlet and discharge plumbing lands right the first time.
