The Chem-Tainer 300 Gallon Vertical Storage Tank (SKU TC3581IC-BLACK) is a black polyethylene vertical tank built for above-ground bulk water storage where you need real volume in a compact footprint. It stands 84.75 inches tall on a 35 x 35 inch base, so 300 gallons occupies a footprint just 35 inches square. The tank carries a 1.5 specific gravity rating, meaning the wall is engineered to hold contents up to 1.5 times the weight of water without deforming.
Will this 300 gallon tank work for your site?
Water fills this vertical storage tank to roughly 2,502 pounds when topped off, and the 1.5 SG rating means the shell is rated to carry contents up to about 3,753 pounds. That headroom is what lets a tank like this handle denser liquids than plain water, but for water service the number that matters is the full-water weight: your stand, ring, or slab has to carry more than 2,500 pounds over a 35 x 35 inch square. Size the base to the tank, not the other way around. If you are still weighing capacities or working out pad loading, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. For an engineered foundation under a filled vertical tank, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework.
Setup and fittings
Set the tank plumb and fully supported on a smooth, level surface with no point loads under the base. Outlet, bulkhead, and gasket configuration is confirmed with you at order time and spec'd to the fluid you plan to store, so you tie into your fill line and gravity or pumped feed with the right seal for the job; see the technical drawing on this page for the tank's dimensions and profile. This is a tall, small-footprint design, so it earns its space in bulk water storage, rainwater capture, hauled-water buffering, and reuse holding alike. If you are aggregating rainwater, grey-water, or condensate streams into it, our guide on industrial water reuse tank topology covers quality-banded storage trains.
The mistake to avoid
The common error on a 300 gallon vertical tank is underbuilding the base. People plan around the empty 84.75 inch tank and forget that a full one puts thousands of pounds through a small square. Match the pad or stand to the full-water weight, and keep the tank out of traffic paths given its height. Underbuilt support is the failure that turns a good vertical storage tank into a leaning liability.
