The Enduraplas 730 Gallon Vertical Water Storage Tank (SKU 45441) is a black, above-ground polyethylene tank built for bulk water storage where you need real volume without a lot of headroom. It stands just 56 inches tall on a 74 x 74 inch base, so it holds 730 gallons as a low-profile, low center-of-gravity tank that fits under low ceilings and doorways and rides better on a trailer. If you are still working out how much storage the job actually needs, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Will it work for your site
This is a vertical storage tank for water and water-based service. Per the technical drawing on this page, it comes with a 2-inch bulkhead fitting (part 63481), a second bulkhead vertically in line with the upper fitting on the same side of the tank, and a 16-inch lid (part 60038) for filling, inspection, and access. The lid gives you room to check levels and service the interior; the bulkhead outlet gives you a clean plumbing tie-in for draw or transfer. A bulkhead is only as good as its gasket, so confirm the gasket material suits your water service, and torque the fitting evenly against the tank wall to keep it from weeping. The wide 74 x 74 inch footprint keeps the tank stable when full, which matters at this capacity.
Weight, pad, and freight planning
Filled to 730 gallons, this tank carries roughly 6,088 pounds of water. That load has to land on a flat, fully supported base. Size the foundation for the full-water weight, not the empty shell — our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework, and after install the hydrostatic test methodology covers water-fill acceptance and settlement monitoring so you catch a leak or a soft spot before the tank is in service.
The mistake to avoid
This is a water storage tank. It is not rated here for chemical service, so do not assume it will hold a heavier-than-water fluid — filling a water-rated tank with a high specific-gravity chemical over-stresses the wall. If your duty is fire reserve, feed storage, or reuse, match the tank to the job first: our writeups on fire-water reservoir design and industrial water reuse topology help you confirm the tank fits the water train. If you need a chemical- or higher-specific-gravity-rated tank instead, call us and we will source the right one.
