The Chem-Tainer 2200 Gallon HDPE Vertical Liquid Storage Tank (SKU TC8696IA) is a White polyethylene vertical tank built for high-volume liquid storage where you need real capacity in a single footprint. It stands 96 inches tall on a square 86 x 86 inch base and holds 2,200 gallons. Full of water it carries about 18,348 pounds. What sets this SKU apart is its 1.9 specific gravity rating: it is the heavy-contents build, engineered to hold up to roughly 34,861 pounds of contents at the rated SG - nearly double the weight of plain water in the same shell. If you are storing dense liquids, that headroom is the reason to choose this version over a lighter-rated tank.
Will this tank work for your application?
This is a vertical HDPE storage tank sized at 2,200 gallons, 96 inches tall, with an 86 x 86 inch square footprint - worth noting if you are comparing against round-footprint verticals that quote a single diameter, since here both base dimensions are 86 inches. The 1.9 specific gravity rating is the number to anchor on: it tells you the tank is rated to hold liquids up to 1.9 times the density of water, which is real weight headroom above plain-water service. Full water weight is 18,348 pounds and the maximum rated contents weight is 34,861 pounds, so the pad and any structure underneath have to be designed for a fully loaded tank, not an empty one. Treat the 1.9 SG strictly as a weight/density spec for sizing your foundation and outlets - and because fitting and bulkhead configuration is confirmed per order for this SKU, call 866-418-1777 before you finalize your plumbing layout.
Foundation and siting
A loaded vertical tank of this size puts significant point load on whatever it sits on. The 86 x 86 inch footprint needs full, level, continuous support across the entire base - no spanning gaps, no soft spots. For a permanent above-ground install, a poured concrete pad sized for the loaded weight is the right call; our concrete pad sizing guide walks through the ACI 360R-10 framework and where the ACI 318 boundary comes in. If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to your real demand. For private fire-protection and rural water-reservoir use, this 2,200-gallon class is a common building block - see our fire-water reservoir design guide for NFPA 22 sizing discipline and cold-climate considerations.
The mistake to avoid
The most common error on a tank this size is treating the headspace as a non-issue. HDPE wall thickness has to carry hydrostatic load at the bottom, but the vapor-saturated headspace at the top is where a surprising share of premature failures actually originate, and standard liquid-side inspection often misses them. If you want to understand the ASTM D1998 sizing logic behind the wall and where to look, read HDPE tank wall thickness at the vapor-saturated headspace. The second mistake is over- or under-buying: if you are weighing this against comparable 2,000-class verticals, our Snyder vs Norwesco vs Chem-Tainer comparison lays out how the brands stack up. You can also check the technical drawing on this page to confirm overall dimensions and fitting positions before you build.
