The Norwesco 5000 Gallon Vertical Liquid Storage Tank (N-40166) is a polyethylene vertical storage tank built for high-volume water and bulk liquid holding, where one large reservoir replaces a bank of smaller tanks. It stands 152 inches tall on a 102-inch diameter footprint, so confirm your pad size and overhead clearance before it arrives. The wall carries a 1.9 specific gravity rating, which gives you real headroom over plain water and the option to store denser liquids without overstressing the polyethylene.
Will this tank work for your job
At 5000 gallons, a full load of water weighs about 41,700 pounds, and the tank is rated to hold contents up to 79,230 pounds at its 1.9 specific gravity rating. That max-rated figure, not the lighter water number, is what your foundation has to be sized for. Pour a level, reinforced concrete pad sized to the full 102-inch diameter and confirm the ground bearing capacity for a static load in the 79,000-pound range. If you are still deciding between one large vertical storage tank and several smaller units, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide to match capacity, height, and footprint to your space.
Use the 1.9 SG rating as capability
The 1.9 specific gravity rating is more than a limit, it is what this wall is engineered to carry. Plain water sits at 1.0, so for water storage you have substantial margin. Beyond water, this tank is rated for liquids up to 1.9 specific gravity, so if you plan to store anything denser than water, verify the target liquid's specific gravity stays at or under 1.9 before you fill. Fitting configuration on a tank this size is confirmed at quote, so finalize your outlet and manifold layout with our team rather than assuming a standard port arrangement.
The mistake to avoid
The most common error on a vertical tank this large is undersizing the foundation. At nearly 41,700 pounds of water alone, and up to 79,230 pounds at full rating, a thin or unlevel pad is the failure point long before the tank itself. The second error is treating the specific gravity rating as optional: 1.9 is the ceiling for liquid density, and exceeding it overstresses the wall. Size the pad for max-rated contents, verify your liquid's specific gravity, and confirm fitting and dimension details against the technical drawing on this page before you commit to plumbing and pad layout.
