The Norwesco 1500 Gallon Black Vertical Storage Tank (SKU 40753) is a 1500-gallon polyethylene vertical built for bulk water and liquid storage where you need real volume in a tight footprint. It stands 116 inches tall on a 64 x 64-inch base, which works out to about 28.4 square feet of floor area for the full 1,500 gallons. The black exterior blocks light, which helps slow algae growth in standing water, and the 1.5 specific gravity rating means the tank wall is built to hold liquids up to 1.5 times the weight of water.
Will it work for your site?
This is a Norwesco vertical storage tank in the 1500-gallon class. Plan your site around the loaded weight, not the empty shell: filled with water it carries about 12,510 pounds, and at its full 1.5 specific gravity rating it can hold up to 18,765 pounds of contents. That load lands on a 64.0 x 64.0-inch footprint, so the pad underneath has to be engineered for it. For a poured base, our concrete pad sizing guide walks through the ACI 360R-10 framework and where the ACI 318 boundary applies. If you are still confirming this is the right capacity for your draw and refill rate, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. One more dimension to check before you buy: 116 inches is 9 feet 8 inches tall, so it will not clear a standard 8-foot (96-inch) doorway or a typical residential garage. Verify both the delivery path and the standing-location height before you order.
Sizing it into a working system
At 1500 gallons this is a common size for fire-water reserves, rainwater and water-reuse trains, and general bulk storage. If you are designing rural or remote fire protection, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze protection for cold-climate service, which matters if the tank will sit in a cold state where standing water can freeze. For reclaimed-water setups, the industrial water reuse tank topology breakdown shows how grey-water, rainwater, and HVAC condensate aggregate into quality-banded storage trains. And because verticals this size need correctly sized venting, the atmospheric vent capacity guide works API 2000 examples for thermal inbreathing, liquid-movement outbreathing, and combined sizing on 1500-to-10000-gallon verticals.
The mistake to avoid
The most common error on a tank this size is undersizing the foundation. An 18,765-pound rated load is not something a gravel pad or a few patio blocks will carry level over time, and a tank that settles unevenly puts stress on the wall and the plumbing connections. Build the pad to spec for the full rated weight and review the dimensions on the technical drawing on this page so your tie-downs, plumbing penetrations, and overhead clearance for the 116-inch height all line up before delivery. The 1.5 specific gravity rating means the wall is built for liquids heavier than water, up to 1.5 times its weight, but this is a water and general-service tank: confirm chemical suitability by phone before storing anything other than water. Fitting configuration (inlet, outlet, lid, and gasketed bulkhead options) is not published per unit, so call 866-418-1777 to confirm fitting sizes before you order.
