The Norwesco 2500 Gallon Black Heavy Duty Vertical Storage Tank is a large-format vertical tank built for serious bulk water storage, standing 79 inches tall on a footprint roughly 102 inches in diameter. It holds 2,500 gallons, and the black polyethylene wall blocks light to discourage algae growth in stored water. With a 1.9 specific gravity rating, this is a heavy-duty shell that carries a meaningful margin over plain water, which is why it shows up in searches for a Norwesco vertical storage tank built to take a beating.
Will this tank work for your site?
Plan around the real footprint and the loaded weight before you pour a pad. The tank stands 79 inches tall on a footprint that fits within a 102 by 102 inch bounding box, so size your base to cover the full circle. Filled with water, the contents alone weigh 20,850 pounds, and the shell is rated to carry up to 39,615 pounds of contents at its full 1.9 specific gravity. That loaded number is what your foundation has to support, not the empty tank weight. For dry weight of the tank itself, see the technical drawing on this page. To confirm the size against your demand and refill cycle, use the Tank Sizing Calculator and the Tank Sizing Guide.
Heavier-than-water service
The 1.9 specific gravity rating is not just a safety cushion. It means this same shell is rated for liquids up to 1.9 SG, roughly 15.85 pounds per gallon, so a buyer storing brine, liquid fertilizer, or other fluids heavier than water can use this exact tank rather than stepping up to a larger or thicker model. Fitting, outlet, and gasket detail are shown on the technical drawing on this page. Confirm your outlet size and gasket material against your plumbing before ordering, since the right gasket depends on the fluid you intend to store.
Pad and foundation
At over 20,000 pounds of water and up to nearly 40,000 pounds of rated contents, a 2,500 gallon vertical tank needs an engineered base. A flat, level concrete pad that fully covers the 102 inch footprint circle keeps the floor evenly supported and the tank plumb. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right.
Where it fits
This size is a common backbone for rural and remote water programs, including fire-water reservoirs and water-reuse trains. If you are stocking water for private fire protection, our piece on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection. For greywater, rainwater, and HVAC condensate aggregation, see our overview of industrial water reuse tank topology.
