The Enduraplas 1400 Gallon Vertical Liquid Storage Tank is a green polyethylene vertical tank built for bulk water and high-density liquid storage, standing 79 inches tall on an 80 x 80 inch square footprint. The headline number is the 1.9 specific gravity rating: the wall is built to carry contents substantially heavier than water. If you searched for an Enduraplas vertical storage tank because you need real load capacity rather than a basic water-only tank, this is the spec that sets it apart.
Will it hold what you're storing?
At full water capacity, this tank carries 11,676 pounds of contents. The 1.9 specific gravity rating pushes the maximum rated contents weight to 22,184 pounds, so you have roughly 10,500 pounds of additional rated load over a standard water-only (1.0 SG) tank, without exceeding the design. That margin is the whole point of buying a 1.9-rated vertical tank instead of a lighter one. Use the Tank Sizing Calculator to confirm your stored volume against the 1,400-gallon capacity, and the Tank Sizing Guide if you're deciding between this and a taller or wider footprint. The crate envelope is fixed at 80 x 80 inches at the base and 79 inches tall, so check door, gate, and overhead clearance against that full envelope before delivery.
Fittings, color, and siting
Fitting and outlet sizes are not listed in this product record, so confirm penetrations and any gasket or bulkhead requirements against the technical drawing on this page, or by calling 866-418-1777, before you plumb it in. The drawing is the authority on outlet and fitting locations for this model. This is solid green polyethylene, not translucent, so the liquid level is not externally visible; plan for a gauge or level sensor if you need to read volume. A loaded tank at 22,184 pounds is a real foundation load, and the base needs to support it evenly on a continuous, level, full-contact pad rather than a ring or piers. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies, so the pad matches the actual contents weight rather than a rule of thumb. If this tank is headed into a fire-water reserve or rainwater reuse role, the fire-water reservoir design guide and the industrial water reuse topology guide cover sizing discipline and treatment-stage sequencing.
The mistake to avoid
The most common error on a vertical tank this size is treating the 1.9 specific gravity rating as a guarantee for every fluid. The rating tells you the maximum contents density the wall is built to carry by weight, not that the polyethylene resin is chemically compatible with any given liquid. Confirm the stored fluid is within the 1.9 rating by weight and is appropriate for polyethylene water-storage service before filling. Also account for the vapor-saturated headspace at the top of the tank, where wall stress and premature failures originate even when the liquid side looks fine; our guide on HDPE tank wall thickness at the headspace explains the ASTM D1998 sizing logic behind it.
