The Enduraplas 210 Gallon Black Vertical Storage Tank (SKU THV00210B) is a 210-gallon polyethylene vertical tank standing 48 inches tall on a 40-inch by 40-inch footprint, rated to a 1.9 specific gravity. That 1.9 rating is the reason to choose this tank over a standard water-grade vertical: most water tanks this size are built to 1.5 SG, so this Enduraplas vessel is engineered to hold heavier, denser liquids up to 1.9 SG without exceeding its design limit. The black polyethylene wall blocks light, which discourages algae growth in stored water compared to a translucent tank.
Will it work for your site?
The two weights that matter for siting are easy to scan: full of water this Enduraplas vertical holds roughly 1,751 pounds, and its maximum rated contents weight is 3,328 pounds at the full 1.9 specific gravity. Size your pad and anchoring to the heavier 3,328-pound figure if there is any chance you will store a liquid denser than water. The 40-inch by 40-inch footprint keeps it compact for tight equipment yards, well houses, and remote pump sheds, while the 48-inch height stays low enough to fill and inspect without a tall ladder. If you are still settling on capacity, our Tank Sizing Calculator and Tank Sizing Guide help you match draw-down and refill rates to your demand.
Fittings and pad foundation
Outlet, lid, and fitting configuration on this tank is verified per order, so call us at 866-418-1777 to confirm the exact bulkhead, inlet, and lid setup for your application before you buy rather than assuming a package. See the technical drawing on this page for dimensional reference. A loaded vertical concentrates real weight on a small footprint, so the slab matters: before you pour, read our walkthrough on concrete pad sizing for above-ground polyethylene tanks and size the pad to the 3,328-pound loaded contents weight, not the empty tank. The most common mistake on a vertical this size is treating the 1.9 SG rating as a license to store any heavy liquid without checking the rest of the system; confirm your fittings, gaskets, and supply line are rated for the same density before you fill.
Sizing it into a larger system
At 210 gallons this storage tank works as a point-of-use buffer, a haul-and-store reservoir, or a building block in a banded storage train. If you are designing fire-water reserve for a rural or remote site, see our guide on fire-water reservoir tank design and NFPA 22 sizing discipline. For water-reuse projects that aggregate grey water, rainwater, or HVAC condensate, our industrial water reuse tank topology guide covers staging multiple vessels into a treatment train, and if you are capturing roof runoff, our rainwater harvesting first-flush diverter guide walks through keeping the dirty first flush out of a black vertical like this one.
This tank ships LTL freight from the Enduraplas plant in Converse, TX, with the carrier rate quoted live to your ZIP code. Because LTL rate and transit scale with distance from Converse, a Texas or South-Central destination quotes lower than a coastal one.
