The Chem-Tainer 1700 Gallon HDPE Vertical Liquid Storage Tank is a white, polyethylene vertical storage tank built for high-volume bulk liquid storage in agricultural water, rural fire reserves, rainwater capture, and general water service. The opaque white wall blocks sunlight to discourage algae growth, which matters for stored water that sits for weeks at a time. What sets this particular tank apart is its 1.9 specific gravity rating, putting it in the heavy-duty class of vertical tanks engineered to carry dense liquids well above the weight of plain water. Below are the working specs, what shipping looks like, and the one detail to get right before you order.
Will this tank work for your application?
This is a 1,700 gallon vertical storage tank rated to a 1.9 specific gravity, which is unusually high for a poly tank this size and means the shell is built to hold dense liquids, not just water. Filled with plain water (specific gravity 1.0), the contents weigh roughly 14,178 pounds; at the full 1.9 rating the tank is engineered to carry up to about 26,938 pounds of contents. Those numbers drive your foundation: size the slab, pad, and any tie-downs for the full loaded weight at your liquid's actual density, not just the water figure. The pack lists a footprint of roughly 86 x 86 inches, but treat any inline dimension as a starting point only and confirm the exact height and diameter against the technical drawing on this page before you pour a pad or plan overhead clearance. If you are still working out whether 1,700 gallons fits your draw rate or storage window, the Tank Sizing Calculator and Tank Sizing Guide will walk you through it.
Sizing and design context
At 1,700 gallons this tank sits squarely in the rural fire-reserve and bulk-water bracket. If you are designing private fire protection, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection. For the engineering behind poly wall thickness, the breakdown of HDPE tank wall thickness and where premature failures originate explains the ASTM D1998 sizing logic worth understanding before you commit. Cross-shopping brands at this size, our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison and the dedicated 1700 gallon vertical liquid storage tank buyer's guide are both worth a read.
The mistake to avoid
The most common error on a high-SG tank like this is assuming the 1.9 rating extends to every part of the system. It does not. The 1.9 specific gravity rating describes the maximum density the shell is built to hold safely; it tells you nothing about the fittings or gaskets. Fitting configuration is not specified for this tank, so confirm the bulkhead size, outlet placement, and gasket material before you order, and make sure every gasket and seal elastomer is rated to the same liquid and density as the tank. A shell rated for dense liquid paired with an undersized or wrong-material gasket is a leak waiting to happen. One more honest note: if you are storing plain water and nothing heavier, you do not need the 1.9 rating, and a standard specific-gravity tank in the same size would carry your water for less weight rating than you are paying for here. Buy the 1.9 because you have a dense liquid, not by default.
