The Enduraplas 650 Gallon Vertical Liquid Storage Tank (SKU 900650-1.2-NAT) is a 72-inch-tall vertical polyethylene tank on a 56 x 56 inch footprint, built for stationary bulk water and liquid storage where a compact base and vertical capacity both matter. At 650 gallons, it sits on the ladder between the 500-gallon and 2000-gallon verticals, and its dimensions are verified against launch specs rather than estimated. If you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match drawdown and refill rate to this size before you commit.
Will it work for your site?
The tank stands 72 inches tall and occupies a 56 x 56 inch square footprint, so plan a level pad at least that wide with clearance for the top and any fill plumbing. Fitting and outlet configuration is not listed in our current spec record for this SKU, so call 866-418-1777 to confirm outlet size and location before you plumb it. This listing covers general water and liquid storage; if your application involves anything beyond water, confirm the tank's suitability for your specific liquid before ordering.
How heavy is it full, and what does the pad carry?
Filled with water at a specific gravity of 1.0, this tank weighs roughly 5,421 pounds. That load sits entirely on the 56 x 56 inch base — about 1.7 pounds per square inch across the full 3,136-square-inch footprint — so the pad, ring, or slab underneath has to carry the standing weight without settling or edge-loading the tank. A poured concrete pad or an engineered gravel ring sized to the full footprint is the safest foundation. The fill weight above is calculated at water's specific gravity of 1.0; a denser liquid raises the standing load proportionally, so confirm the tank's rated specific gravity against your liquid before ordering. The most common mistake on a vertical tank this size is setting it on soil or uneven timber that shifts once it is full, which stresses the tank wall and floor. Get the pad flat, level, and continuous before delivery.
Freight and ordering
This 650-gallon vertical tank ships LTL freight on a pallet or skid. Because freight is priced by destination, we quote it live to your ZIP through the Freight Cost Estimator rather than bundling it into the list price. For a straight vertical water-storage build, this Enduraplas tank pairs well with our rural and fire-reserve planning guidance, including the fire-water reservoir design guide. It sizes up cleanly to the 2000-gallon vertical or steps down to the 500-gallon vertical and 300-gallon vertical if your capacity needs change. Questions on fit, freight, or lead time?
