The Chem-Tainer 165 Gallon Vertical Storage Tank (SKU TC3158IC-NAT) is a Natural White polyethylene vertical tank built for straightforward bulk water storage where a compact 31-inch footprint matters. It stands 58 inches tall on a 31 x 31 inch base, so it tucks into a corner, a pump house, or a tight equipment yard without eating floor space. If you have been searching for a white vertical storage tank in the 165-gallon class, this is the size that holds real volume while staying easy to site.
Will it work for your water?
This vertical tank holds 165 gallons. Full of water, contents weigh about 1,376 pounds, and the pad or platform under it has to carry that load plus the tank itself, so set it on a level, fully supported surface - a poured slab or a continuously supported deck, never on point supports or uneven ground. The polyethylene wall is rated to a 1.5 specific gravity, which means it is engineered for contents up to 1.5 times the weight of water - a maximum rated contents weight around 2,064 pounds. That is a real buying reason: unlike a water-only 1.0-SG tank, this one will legitimately hold heavier solutions within that SG limit. Confirm your fit with the Tank Sizing Calculator and the Tank Sizing Guide before you plumb it.
Siting, pad, and stability
A vertical storage tank this size lives or dies on its base. At 58 inches tall on a 31 x 31 inch footprint, the height-to-width ratio is about 1.9:1 - genuinely tip-sensitive when full or during fill and drain surge, so anchor or strap the tank in seismic, wind-exposed, or elevated installs. Because the loaded weight concentrates on that small base, ground pressure runs higher than it looks; a firm, level pad keeps the tank from leaning or stressing the outlet. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through getting the slab right. For fire-reserve, rainwater, or reuse duty, see the fire-water reservoir design guide and the industrial water reuse topology guide.
The mistake to avoid
The common error on a compact vertical is treating the small footprint as forgiving - it is the opposite. The same weight over less base means you cannot cheat the pad or run it half-supported. And do not guess your plumbing: fitting sizes, bulkhead and outlet locations, and gasket requirements are per the technical drawing on this page, so confirm those on the drawing before you order pipe or seals. Get the level base right, support the outlet, and match the drawing.
