The Chem-Tainer 2100 Gallon Vertical Storage Tank (SKU TC8787IC-BLACK) is a black polyethylene vertical storage tank built for bulk water and general liquid storage. It stands 87 inches tall within an 87 x 87 inch bounding footprint - a nominal 87-inch round diameter per the technical drawing on this page - so it holds serious volume without a sprawling pad. The tank carries a 1.5 specific-gravity rating, which is the number that tells you how heavy a liquid it can safely hold.
Will this tank work for your site?
Filled with water, this tank weighs about 17,514 lb, and at its full 1.5 specific-gravity rating it can carry up to 26,271 lb of contents. That gap - roughly 8,757 lb, about 50 percent of density headroom above water - means the wall is nowhere near stressed in plain-water service. The loaded weight is what your pad and site prep need to account for: plan a level, engineered foundation sized for the full contents load. Our concrete pad sizing guide walks through the ACI framework for above-ground poly tanks. If you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand before you buy, and our 2000 gallon vertical storage tank comparison shows how this size stacks up across manufacturers.
What the 1.5 rating means - and the mistake to avoid
The most common mistake with a vertical storage tank is reading specific gravity backward. A 1.5 SG rating means the wall is built to hold liquids up to 1.5 times the weight of water. Water sits at 1.0, so this tank has ample margin above water's density. The rating is a ceiling on liquid density, not a promise about any particular chemical - confirm the tank resin along with the fitting and gasket materials against the liquid you plan to store before committing to anything heavier or more aggressive than water. Fitting and outlet detail is not specified in our data for this SKU, so confirm outlet size, placement, and gasket material against the technical drawing or the OEM before ordering gaskets or bulkhead fittings. For a fire-water reservoir or other standby supply, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
Applications
This 2100 gallon black vertical tank suits rural and municipal water storage, irrigation supply, rainwater capture, and industrial water reuse trains where grey-water, rainwater, and condensate get aggregated into quality-banded storage - our water reuse topology guide maps out those systems. The black color helps limit light penetration and algae growth in outdoor installations.
This tank ships LTL freight from the Chem-Tainer plant in Hanford, CA, quoted live to your ZIP code. Because a 2,100-gallon tank is oversize freight moving from a single California plant, East and Midwest ZIPs should expect a long-haul LTL run - get an exact number with our Freight Cost Estimator before committing, or call 866-418-1777 and we will handle the quote for you. List price shown is before freight.
