The Chem-Tainer 65 Gallon Vertical Liquid Storage Tank (SKU TC2342IC) is a compact polyethylene vertical tank for water and general liquid storage where floor space is tight. It stands 42 inches tall on a 23 by 23 inch footprint, so it tucks into a corner, a utility room, a pump house, or the bed of a truck while still holding a useful 65 gallons. If you have searched for a 65 gallon vertical storage tank, a vertical tank, or a Chem-Tainer vertical tank for a small reservoir, this is the size that fits a small space without stepping up to a horizontal or flat-bottom design.
Will it work for your liquid?
This tank is molded from polyethylene and carries a 1.5 specific gravity rating, meaning the wall is built to safely hold contents up to 1.5 times the weight of water. Filled with plain water, the 65 gallons weighs roughly 542 pounds, and the tank is rated to carry contents weighing up to 813 pounds (542 lb water times 1.5). That headroom is why the 1.5 SG rating matters: water is 1.0 SG, so for clean-water service you have a wide margin, and for denser liquids you should confirm your fluid's specific gravity stays at or below 1.5 before filling. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 65 gallon capacity to your draw-down and refill needs.
Fittings, gaskets, and placement
This listing does not specify factory fitting or gasket details, so before you plumb the tank, refer to the technical drawing on this page for outlet and bulkhead locations and sizes, and confirm the gasket and seal material separately for your intended liquid. The flat 23 by 23 inch footprint should sit on a smooth, level, fully supporting surface that carries the entire base of the tank, because a full vertical tank concentrates real weight on a small area. For above-ground placement on a slab, the engineering principles in our guide on concrete pad sizing for above-ground polyethylene tanks apply at every scale.
The mistake to avoid
The most common error with a vertical tank this size is treating the specific gravity rating as a guarantee for any liquid. The 1.5 SG rating describes the structural weight limit, not chemical suitability. Polyethylene resin and gasket materials react differently to different chemicals regardless of weight, so a tank that easily carries the weight of a denser fluid is not automatically compatible with that fluid. For plain water and general non-aggressive liquids this tank is a straightforward choice; for anything else, verify chemical compatibility and confirm your fluid stays within the 1.5 SG limit first. At 1.5 SG, this is already the top weight tier in this Chem-Tainer line, so if you are still sizing the system upward, compare against larger vertical options in our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison. For larger water-reserve and reuse planning, our guides on fire-water reservoir design and NFPA 22 sizing and industrial water-reuse tank topology cover the larger-reservoir end of the system.
