The Chem-Tainer 2150 gallon vertical liquid storage tank is a polyethylene bulk tank built for high-density water and liquid storage, standing 99 inches tall on an 86-inch-diameter round footprint. If you have been searching for a vertical storage tank in the 2000+ gallon class, this is one of the larger single-tank options before you step up to multi-tank trains, and its 1.9 specific gravity rating gives you real headroom over plain water.
Will this tank work for your application?
Capacity is 2,150 gallons in a vertical, polyethylene configuration. The 1.9 specific gravity rating is the heavy-duty tier on this Chem-Tainer: many vertical storage tanks ship at a standard 1.0 to 1.5 SG, so a 1.9 wall is engineered to hold liquids substantially denser than water without overstressing the shell. Filled with water at full volume, contents weigh roughly 17,931 lbs; at the maximum rated 1.9 SG, contents can reach about 34,069 lbs. That ~16,000 lb delta is exactly why you would choose this tank over a standard-wall 1.0 SG vertical of the same size, and it is also why your pad, anchoring, and site access have to be sized for the rated load, not just the water figure. The tank stands on a round 86-inch-diameter footprint at 99 inches overall height. Outlet and fitting configuration is not published on this page, so confirm outlet size and locations against your plumbing run by calling 866-418-1777 before you order.
Sizing the pad and the load
A vertical tank this size lives or dies on its foundation, and the pad has to extend past the full 86-inch diameter, not just sit under it. The difference between the water weight and the maximum rated weight is more than 16,000 lbs, so spec the slab for the actual liquid you intend to store, not for water by default. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity and headspace, and review our concrete pad sizing framework before pouring. If this tank is going into a rural fire-water or reservoir role, the fire-water reservoir design guide walks through NFPA 22 sizing and freeze protection.
The mistake to avoid
The 1.9 SG rating is the headline spec here, and it is also where buyers trip up. A high SG rating tells you the tank can structurally handle a denser liquid, but it does not by itself qualify the tank for any specific chemical or for potable use. The polyethylene shell and the wetted elastomers are separate components: gaskets, O-rings, and fitting bulkhead materials must be chemical-matched independently (EPDM versus Viton versus Buna-N) for whatever you store, because SG covers the structure while the elastomers cover the chemical contact. Match the contents to the resin, verify the fitting and gasket materials, and do not assume a heavier-duty wall changes what the polyethylene is rated to contact.
