The Chem-Tainer 650 Gallon Plastic Vertical Liquid Storage Tank (SKU TC5670IA) is a 650-gallon vertical storage tank molded in natural white polyethylene and built to the 1.9 specific gravity rating, the heavy-duty spec that lets you store liquids well past water density. It stands 70 inches tall on a 56 x 56-inch footprint, so before you order, confirm overhead clearance and that the pad you have matches those numbers. This is a vertical bulk storage tank for water and general liquid storage above ground.

Will it hold what you need?
At 650 gallons of fresh water you are carrying roughly 5,421 pounds of contents at full fill, and the tank itself is engineered to a maximum rated contents weight of 10,300 pounds. The 1.9 specific gravity rating is the reason this vertical tank shows up under searches for a white vertical storage tank when buyers need more than a plain water barrel: it is built to carry liquids substantially heavier than water, not just fresh water. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 56 x 56-inch footprint to your draw-down rate and refill schedule before you commit, and run the Freight Cost Estimator early since a 5,400-plus-pound shippable item makes freight your biggest variable.
Pad and placement
A loaded vertical tank of this size belongs on a flat, fully supporting base. With more than 5,400 pounds of water bearing down through the 56-inch footprint, the pad has to carry the full standing load with no voids or overhang under the tank floor. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that base right. If this tank is going into a rainwater-capture or water-reuse train, our guide on industrial water-reuse tank topology covers sizing and layout for those applications.
The mistake to avoid
Do not assume the fittings on the tank you receive match a drawing you found elsewhere. There is no factory fitting or gasket configuration published for this SKU, so verify the outlet and bung placement against the technical drawing on this page before you plumb your supply or discharge line. Confirm both the bulkhead fitting size and the gasket material against that actual drawing, then order to match. The 1.9 SG rating gives you margin on contents weight, but it does not change the fact that fitting placement and inlet/outlet sizing have to be confirmed against the drawing for this model, not a similar one.
This tank ships LTL freight, quoted live to your ZIP from the Hanford, California plant, which is a real freight advantage for Western buyers. Get an exact number with the Freight Cost Estimator, or call 866-418-1777 to confirm fittings, lead time, and delivery before you order.
