The Enduraplas 8000 Gallon Dark Green Vertical Water Storage Tank is built for serious bulk-water duty, where one large reservoir beats a cluster of smaller tanks. This is a vertical water tank molded from polyethylene with a 1.1 specific gravity rating, standing 142 inches (11.83 feet) tall on a 144 x 144 inch footprint, exactly 12 feet square. At full water capacity it holds 8,000 gallons, so site planning starts with the pad, the access, and the freight before anything else.
Will it work for your site?
The numbers that govern this water storage tank are weight and footprint, not just gallons. Filled with water it carries roughly 66,720 pounds, and at the 1.1 specific gravity rating its maximum rated contents weight is 73,392 pounds. That margin above plain water (SG 1.0) gives mechanical headroom for slightly denser or sediment-laden water without overloading the wall, though this is a water tank and is sized for water service. The load lands on a 144-inch base, and because this is a vertical tank with equal width and length, that 144-inch dimension is the diameter, so you need a clear 12-foot circular spread plus pad overhang, not just a 12-foot square edge to edge. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 8000-gallon size against your draw rate and refill schedule, then read our guide to concrete pad sizing for above-ground polyethylene tanks (ACI 360R-10 framework) so the foundation matches the contents weight above. See the technical drawing on this page for dimensional detail, and confirm the exact fitting layout by phone at 866-418-1777 before you order.
How it ships
A vertical storage tank this size moves by LTL freight, quoted live to your ZIP. It ships from the Enduraplas plant in Converse, TX, which is the named ship-from point for this tank. Because freight cost depends entirely on distance and delivery conditions, run your ZIP through the Freight Cost Estimator or call 866-418-1777 for a quote. It offloads as an 11-foot-10-inch upright unit, so plan your crane or forklift reach and a clear access path before the truck arrives, since 142 inches upright can exceed standard trailer clearance.
The mistake to avoid
The most common error on a tank this large is treating the pad and the fill as an afterthought. With more than 66,000 pounds of water bearing on the base, an undersized or unlevel foundation is the fastest way to compromise a polyethylene water storage tank. After install, fill it deliberately and monitor for settlement rather than topping it off all at once. Our hydrostatic test methodology for new-install tank acceptance walks through fill discipline, pad-settlement monitoring, fitting leak detection, and hold-time math. If this reservoir is part of a rural fire-protection plan, our fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection, and for grey-water, rainwater, or HVAC condensate aggregation see our industrial water reuse tank topology guide.
