The Enduraplas 2100 Gallon Black Vertical Storage Tank (SKU THV02100B) is a polyethylene vertical storage tank built for bulk water and general liquid storage where a tall, compact footprint matters. It stands 100 inches tall on an 85 x 85 inch base and holds 2,100 gallons, so you get real volume without spreading across a wide pad. The black shell limits light penetration to slow algae growth in outdoor water storage, and the 1.9 specific gravity rating means this Enduraplas vertical tank is engineered for liquids heavier than plain water.
Will this tank work for your site?
Start with weight, because it drives the whole install. Filled with water this tank carries roughly 17,514 pounds of contents; at its full 1.9 specific gravity rating it is built to hold up to about 33,277 pounds. That 1.9 rating is the buying reason on this unit: it handles denser, heavier-than-water liquids up to 1.9 SG that most water-only tanks are not built for. Spread the loaded weight over the 85 x 85 inch base and your foundation and soil need to carry roughly 660 pounds per square foot at full 1.9 SG, so a level, fully supporting pad is not optional. Size the pad to the loaded weight, never the empty tank. For volume and pad planning, use the Tank Sizing Calculator and the Tank Sizing Guide, and our guide to concrete pad sizing for above-ground polyethylene tanks walks the ACI framework for a load this heavy.
Common uses and cold-climate notes
At 2,100 gallons in a black vertical storage tank profile, this is a common choice for rural and remote water storage, including fire-water reservoir duty; our write-up on fire-water reservoir tank design covers NFPA 22 sizing and freeze protection. The black shell absorbs solar gain, which helps in cold climates, but it is not freeze-proof, so plan heat or insulation for winter service. For reuse plumbing, see the industrial water reuse tank topology guide and our rainwater harvesting first-flush diverter guide.
The mistake to avoid
Do not order plumbing, valves, or a pump before you confirm the actual fitting layout. Call us at 866-418-1777 and we will verify the inlet and outlet positions and sizes on this specific tank so your connections match on the first try rather than assuming a standard configuration.
This tank ships LTL freight, quoted live to your ZIP from the nearest stocking plant. The Converse, TX plant serves the South and Southwest; the Neche, ND plant serves the Northern Plains and Upper Midwest, so freight tracks to whichever is closer to you. Get an exact number with the Freight Cost Estimator, or call 866-418-1777 and we will help you lock in the right vertical storage tank and delivery.
