Chem-Tainer 1700 Gallon Vertical Storage Tank

The Chem-Tainer 1700 Gallon Vertical Storage Tank (SKU TC1701IC-BLACK) is a round black polyethylene vertical tank, roughly 86 inches across the base and 78 inches tall, rated for 1,700 gallons. It carries a 1.5 specific gravity rating, meaning the wall is built to hold contents heavier than plain water. For bulk water storage, rainwater capture, a rural fire-water reserve, or process-water buffering, this is a straightforward high-capacity vertical tank that sets on a prepared pad and fills from the top.

Will it hold your volume and weight?

Filled with water, 1,700 gallons weighs about 14,178 pounds. At the full 1.5 specific gravity rating, the tank is engineered to carry up to roughly 21,267 pounds of contents — that ~7,000-pound gap above water-full is your margin for heavier, denser fluids. All of that load lands on the ~86-inch round base, so the foundation matters as much as the tank. Size the tank to your real draw before you buy: our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to daily demand so you are not over- or under-buying a vertical storage tank of this class.

Set it on the right foundation

A vertical tank this heavy needs a full, level, continuously supported base — the entire round footprint must bear evenly, with no overhang and no point loads. Our concrete pad sizing guide covers the ACI framework for above-ground polyethylene tanks so the pad carries the loaded weight without cracking or settling unevenly. Review the technical drawing on this page for outlet and fitting locations, and confirm that placement against your plumbing plan before you set the tank.

One thing not to get wrong

Confirm the 1.5 specific gravity rating covers what you actually intend to store. Plain water sits at 1.0, so this tank has ample structural margin for non-potable water duty, greywater, and rainwater. The 1.5 rating is a structural strength rating, not a chemical-service endorsement — if your contents are anything other than water, call us first so we match you to the right tank and confirm outlet size and fitting placement before shipment.
