The 500 Gallon Plastic Water Storage Tank from Norwesco is a vertical polyethylene tank that holds 500 gallons in a 48-inch diameter footprint and stands 73 inches tall. It is built for above-ground water storage where a compact circular footprint and straightforward gravity or pump-fed plumbing matter more than horizontal sprawl. If you are searching for a 500 gallon vertical water storage tank for a well system, equipment yard, or rural water-supply setup, this is the size and shape that fits a small pad.
Will it work for your water storage job
At 48 inches in diameter the tank occupies a small slab, so it fits pump houses, well systems, and tight equipment yards. Before delivery, confirm the 48 in diameter clears your door or gate width and that the 73 in height clears any overhead obstruction or roofline. Filled to capacity it carries 4,170 pounds of water, and that full water weight is also the maximum rated contents weight, so the pad and any platform underneath must support the loaded figure plus the empty tank. This Norwesco tank carries a specific gravity rating of 1.0, which covers water and water-density liquids; it is not rated for liquids heavier than water. If you are weighing this 500-gallon vertical against a taller or horizontal alternative, run your numbers through the Tank Sizing Calculator and review the Tank Sizing Guide to match volume and height to your site.
Fittings, mounting, and head pressure
Fitting size, outlet count, and lid details are not listed in this product record, so read them off the technical drawing on this page, or call 866-418-1777 to confirm before you trench plumbing or pour a pad. Gasket material on any bulkhead fitting should be verified against your fluid at order time. The 73-inch tall body gives you some usable gravity head at a bottom outlet without a stand, but the actual delivery pressure depends on where the outlet sits, which is another reason to check the drawing first. Set the base on a level, fully supported surface. For the slab itself, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for sizing to the loaded weight.
The mistake to avoid
The most common error with a vertical water tank this size is treating the specific gravity rating as flexible. This tank is rated to 1.0, which means water. Filling it with a heavier-than-water liquid puts stress on the wall the tank was not engineered for. Keep it in water service. If you need to store a chemical or a heavier liquid, call 866-418-1777 for a chemical-rated tank instead. If your application is fire-protection reserve or reuse storage, read the fire-water reservoir tank design guide or the industrial water reuse tank topology guide to confirm this size fits before you order.
