The Chem-Tainer 2100 Gallon Black Vertical Water Storage Tank (SKU TC8787IW-BLACK) is a polyethylene vertical water tank built for bulk water storage where a tall, compact footprint matters. It stands 87 inches tall on an 87-inch round footprint and holds 2,100 gallons in a single upright vessel. The black resin blocks light transmission, which suppresses algae growth in stored water - the practical reason black is chosen for outdoor water storage rather than appearance alone.
Will this tank work for your application?
This vertical storage tank carries a 1.0 specific gravity rating, meaning the wall is engineered for water and water-weight liquids at that density. Filled to its 2,100-gallon capacity, the water alone weighs 17,514 pounds, and the tank's maximum rated contents weight is the same 17,514 pounds - so plain water fills it to the structural limit with no margin for heavier liquids. The footprint is 87.0 x 87.0 inches; confirm clearances and gate widths before delivery. One detail worth settling up front: fitting and gasket configuration is not published for this SKU, so confirm bulkhead outlets, gasket material, and lid size by calling 866-418-1777 or asking when you pull your freight quote, rather than assuming a layout. If you are still deciding between sizes, the Tank Sizing Calculator and the Tank Sizing Guide will help you match capacity to demand.
How it ships
This water storage tank ships LTL freight from the Hanford, CA plant, quoted live to your ZIP code. A 2,100-gallon vertical tank is an oversized load, so freight is handled as a less-than-truckload shipment rather than parcel. It ships empty and light - the bare shell can be placed by a forklift or a small crew - but every pound of the 17,514-pound load is added on site, so siting accuracy matters before the first fill, not after. Get an exact number for your delivery address with the Freight Cost Estimator before you order, or call 866-418-1777 and we will quote it with you.
The mistake to avoid
The single most common error on a tank this size is treating the 1.0 specific gravity rating as flexible. It is not. This wall is sized for water; a denser liquid at the same fill level would exceed the 17,514-pound rated contents weight and overstress the tank. Keep it on water-weight service - if you need to store anything heavier than water, call 866-418-1777 and we will point you to a vessel rated for the higher specific gravity instead. The second mistake is under-building the base. With the full load reaching more than 17,500 pounds, the pad has to carry that concentrated weight without settling or cracking, which is exactly what trips up rushed installs. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that foundation right. In cold climates, remember that an 87-inch standing water column needs freeze planning before winter service.
