The Enduraplas 2520 Gallon Black Vertical Storage Tank (SKU THV02520B) is a polyethylene bulk water tank built for high-volume above-ground storage. It holds 2,520 gallons in a black, UV-shielded vertical body measuring 110 inches in diameter and 86 inches in overall height, seated on a 110 x 110 inch footprint (the square bounding box around the 110-inch circular base). The black resin blocks light penetration, which suppresses algae growth in stored water - a practical reason many buyers pick a black vertical storage tank over a translucent one for outdoor water service.
Will this Enduraplas vertical tank work for your site?
This tank carries a 1.9 specific gravity rating, meaning the wall thickness is built to support contents up to 1.9 times the density of water. For plain water storage that leaves a wide margin. Called out as discrete foundation specs: a full load of water weighs 21,017 lb, and the tank is rated to carry contents up to 39,932 lb at its 1.9 SG rating. Design your pad around the loaded weight, not the empty shell. Before you set it, confirm the 110-inch base clears your pad and access route, and verify inlet and outlet positions against the Enduraplas manufacturer specifications and the technical drawing on this page before you plumb it in. If you are still sizing the tank to your draw and refill cycle, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand.
Foundation and site planning
At more than 21,000 lb full, this tank demands a properly engineered base: a level, continuously supported pad, most commonly a reinforced concrete slab. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting the slab right. Where a black vertical tank of this size serves as a rural fire-protection reservoir, see our write-up on fire-water reservoir tank design and NFPA 22 sizing. If you are aggregating grey water, rainwater, or HVAC condensate, our industrial water reuse tank topology guide covers how a tank like this fits a reuse train.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation. The 1.9 specific gravity rating is not permission to skip pad engineering for water service - the loaded weight is what drives your slab design, and an unlevel or undersized base is the leading cause of stress cracking on large vertical tanks. Set it level, set it fully supported, and confirm your fitting locations against the manufacturer specifications before plumbing.
