Chem-Tainer 750 Gallon Plastic Vertical Liquid Storage Tank

The Chem-Tainer 750 Gallon Plastic Vertical Liquid Storage Tank is a polyethylene vertical storage tank built for liquid storage where you need real headroom on a compact slab. It stands 119 inches tall on a 46 x 46 inch base and holds 750 gallons. Three numbers decide whether this 750 gallon tank fits your project: capacity, the weight it puts on your slab, and the specific gravity of whatever you plan to store. This page covers all three, plus how it ships.

Will it work for your application?

This is a 750 gallon vertical tank molded from polyethylene with a 1.5 specific gravity rating. The footprint is 46 x 46 inches and the overall height is 119 inches, so confirm your overhead clearance and fill access before delivery. The 1.5 SG rating means the wall is engineered to carry liquids weighing up to 1.5 times the weight of water, which covers water and a range of heavier liquids up to that rating. Filled with water, the contents weigh 6,255 pounds; loaded to the full 1.5 SG rating, the contents can reach 9,382 pounds. Those are the loads your pad, foundation, or containment area has to carry, so size your base for the heaviest liquid you actually intend to store, not just for water.

Sizing and site planning

Because this is a tall, narrow vertical tank, the load is concentrated on a small footprint, which makes a level, reinforced base more important than it would be on a wide, low tank. At the full 1.5 SG rating, 9,382 pounds sits on a 46 x 46 inch base, roughly 2,116 square inches of bearing area, which gives your slab engineer a load-per-area starting point to design from. Use the Tank Sizing Calculator to confirm 750 gallons matches your draw-down and refill schedule, and read the Tank Sizing Guide if you are still deciding between a vertical and a horizontal layout. If this storage tank is headed into rural fire-water or remote-site service, the fire-water reservoir tank design guide walks through NFPA 22 sizing discipline and freeze protection for cold-climate installs.

The mistake to avoid

The most common error on a vertical storage tank like this is pouring the slab for water and then filling it with something heavier. At a 1.5 specific gravity your contents weigh about 50 percent more than water, which is the difference between a 6,255-pound load and a 9,382-pound load on the same 46 x 46 footprint. Confirm the specific gravity of your liquid against the 1.5 rating before you order, and pour or verify your base for that worst case. Fitting positions and outlet locations are not published in our spec data for this SKU, so check the technical drawing on this page for fitting locations and tank geometry before you set anchors or plumb your inlet and outlet.

This 750 gallon Chem-Tainer vertical tank ships LTL freight from the plant in Merced, CA, with freight quoted live to your ZIP. Because it ships from a single California plant, buyers far from the West Coast should expect a higher LTL number, so pull your exact cost with the Freight Cost Estimator rather than guessing, or call 866-418-1777 and we will quote it for you.
