The Chem-Tainer 65 Gallon HDPE Vertical Liquid Storage Tank (SKU TC2342IA) is a compact, free-standing polyethylene vertical tank built for liquid storage where floor space is tight. It stands 42 inches tall on a 23 x 23 inch footprint, and that 23-inch width is the load-bearing fact: it clears a standard interior door opening, so the tank tucks into a pump house, utility room, trailer bed, or the corner of a shop while still holding a useful 65 gallons. It is molded in natural white polyethylene, which lets you read the liquid level through the wall, and it carries a 1.9 specific gravity rating - engineered to hold contents substantially heavier than water without over-stressing the wall.
Will this 65 gallon vertical storage tank work for your liquid?
Sizing is where most buyers either over-build or under-build, so start with the weights. Filled with plain water, this 65 gallon HDPE vertical tank carries roughly 542 pounds. Because it is rated to a 1.9 specific gravity, the maximum rated contents weight climbs to about 1,030 pounds. That spread - 542 pounds of water versus a 1,030-pound ceiling - is the buying reason: anything denser than water and up to 1.9 specific gravity is already covered, so you can store water today and a heavier solution later without stepping up to a separate, heavier-rated vessel. Confirm the specific gravity of your liquid against that 1.9 rating before you fill. If you are weighing this size against a larger one, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide so the footprint and fill weight match your pad and your pump.
Dimensions and mounting
This vertical storage tank measures 42 in H x 23 in W x 23 in L on a 23 x 23 inch footprint. At 542 pounds full of water and over 1,000 pounds at full rated load, it needs a flat, fully supported base - poured concrete, a stout platform, or a level compacted surface that carries the entire 23 x 23 inch footprint. Polyethylene tanks transfer their whole load to the floor beneath them, so partial support or an unlevel pad concentrates stress in the wall. If you are setting this on a new pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for sizing the slab under an above-ground poly tank. Fitting locations and sizes for this tank are confirmed by phone before order, so you get the correct fill, outlet, and vent layout for your application.
The mistake to avoid
The common error on a smaller vertical tank like this one is treating the headspace at the top of the wall as an afterthought. On HDPE storage tanks, the vapor-saturated zone above the liquid line is frequently where premature wall problems start, and a liquid-side inspection can miss them entirely. Before you put this tank into long-term service, read HDPE tank wall thickness at the vapor-saturated headspace so you know where to inspect and why the wall is sized the way it is.
