The Norwesco 525 Gallon Vertical Liquid Storage Tank (SKU N-41490) is a 78-inch-tall polyethylene vertical tank standing on a 46-inch diameter footprint, built for above-ground bulk liquid storage where a tall, compact column saves floor space. The polyethylene shell carries a 1.5 specific gravity rating, meaning it is structurally rated to hold contents up to 1.5 times the weight of water - useful headroom if you are storing a liquid denser than water rather than water alone. If you have been searching for a Norwesco vertical storage tank in this capacity, this is the standard 525-gallon vertical configuration.
Will it work for your site?
The numbers that matter for placement and rigging are straightforward. Filled with water, the tank and contents weigh about 4,378 lbs; at the maximum 1.5 SG structural rating the contents can reach roughly 6,568 lbs. Size your pad, anchoring, and equipment access around the heavier figure if you intend to store a dense liquid - not the water-only weight. The footprint is 46 inches in diameter, so the entire load sits over that single circle; a slab sized only for the water weight will be under-built for full-rated service. The 78-inch height means you will also want to confirm fill-port clearance and overhead access for a hose or downspout. For help matching capacity and dimensions to your draw-down needs, run the Tank Sizing Calculator or read the Tank Sizing Guide before you order. See the technical drawing on this page for fitting locations and overall layout.
How freight works
This tank ships LTL freight from the Norwesco plant in Burnet, TX - the nearest fulfillment point for this SKU - and freight is quoted live to your ZIP rather than bundled into the list price. A 525-gallon vertical tank is a large, low-density item, so the carrier and packaging matter to the final number.

The mistake to avoid
The most common error on a tank like this is treating the 1.5 SG rating as a license to fill it heavy without checking the contents weight against your foundation. At full 1.5 SG service the contents alone push toward 6,568 lbs, all bearing down over a 46-inch circle, and a pad or stand sized only for water can crack or settle. Pour and reinforce the slab for the heaviest liquid you intend to store - the concrete pad sizing guide walks through the ACI framework for above-ground poly tanks. If this is headed into a rural fire-water or reservoir role, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and for grey-water or rainwater aggregation see the industrial water reuse topology guide.
