The Norwesco 525 Gallon Plastic Water Storage Tank is a vertical polyethylene storage tank standing 78 inches tall on a 46-inch diameter footprint, shipping from Norwesco's plant in Burnet, TX. It holds 525 gallons of water and is built for vertical storage where you need real capacity without a wide ground footprint. If you have been comparing Norwesco water storage tanks, vertical storage tanks, or general water storage for a tight pad, this is the size that does the work.
Does it fit your job and your space?
The tank measures 78 inches in height and sits on a 46-inch diameter circular footprint, so plan your pad and overhead clearance around those numbers. The molded polyethylene body carries a specific gravity rating of 1.0, meaning it is rated for water and water-weight liquids at that density. Use the Tank Sizing Calculator to confirm 525 gallons matches your draw-down needs, and the Tank Sizing Guide if you are choosing between sizes. Before you plumb suction or fill lines, confirm the fitting layout from the technical drawing on this page rather than assuming a port location.
Weight and pad planning
Filled with water, this tank carries a full contents weight of 4,378 pounds, which is also its maximum rated contents weight. That entire load sits on the 46-inch diameter footprint, so the pad underneath has to be level, full-contact, and engineered for that concentrated weight. For pad design, see Concrete Pad Sizing for Above-Ground Polyethylene Tanks. After install, fill and check the pad and fittings using the method in Hydrostatic Test Methodology for New-Install Tank Acceptance. Refer to the technical drawing on this page for fitting locations and overall dimensions before you set the tank.
The mistake to avoid
The single most common error with a tank this size is treating the 1.0 specific gravity rating as a license to store anything liquid. It is rated for water at SG 1.0. Heavier liquids exceed that rating and the load the wall and fittings can safely carry. If you need to store something denser than water, do not force it into this tank, call us at 866-418-1777 and we will point you to the right rating. If your stored water also serves a secondary role, such as fire-water reserve or reuse storage, size and plumb it for that use up front rather than after the tank is set. For rural fire-water planning, see Fire-Water Reservoir Tank Design for Rural and Remote Sites, and for grey-water or rainwater aggregation, the Industrial Water Reuse Tank Topology guide.
