The Norwesco 5000 Gallon Plastic Water Storage Tank (SKU N-40641) is a black, vertical polyethylene tank measuring 102 inches in diameter and 152 inches tall, built for bulk water storage where one large reservoir beats a cluster of smaller drums. It holds 5,000 gallons and carries the full water load through its molded sidewall, so it suits water backup, irrigation supply, livestock water, rainwater collection, and rural fire-water reserve. The black resin blocks light to discourage algae growth, which is why this is a common pick for outdoor water storage and vertical storage tank installs.
Will it work for your site?
This tank carries a specific gravity rating of 1.0, meaning it is engineered to hold water and water-density liquids - not heavier chemical solutions. Plan the foundation around the real numbers: a flat, level pad that fully covers the 102-inch-diameter footprint and carries roughly 41,700 pounds of contents at full capacity, with no overhang and no soft spots. A partially supported base is the most common cause of premature sidewall stress on a tank this size. Account for height too - at 152 inches (12 feet 8 inches) tall, confirm overhead clearance for the delivery truck's offload and for any roofed or enclosed location before you order. If you are weighing this tall 102 x 152 profile against a wider, shorter 5000-gallon option, compare it directly with the 119 x 112 low-profile buyer's guide, and use our Tank Sizing Calculator and Tank Sizing Guide to match the dimensions to your space and clearance.
Fittings and connections
Inlet, outlet, lid, and gasket details are not part of the listed spec data for this SKU, so don't assume a particular plumbing configuration. Call us at 866-418-1777 to confirm the available fitting and gasket setup for N-40641 before you order, so your pump, fill line, and overflow plan match what the tank ships with.
What freight looks like
A 5000-gallon tank of this height ships LTL (freight truck), not parcel. Norwesco molds this tank at several plants - Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Merced, CA; Owego, NY; Shawnee, OK; Tooele, UT; and Washougal, WA - and we ship from the plant nearest your delivery ZIP to keep transit short and freight reasonable. Because the rate depends on your destination, get an exact number with the Freight Cost Estimator before you order, or call 866-418-1777 to confirm the nearest stocking plant and lead time.
The mistake to avoid
The trap on a 1.0 specific-gravity water tank is storing anything denser than water in it. Liquids that exceed water density will overstress a tank rated for water service - that calls for a tank with a higher specific-gravity rating instead. If your liquid is heavier than water, call 866-418-1777 so we can route you to a compatible higher-SG tank rather than risk this one. Keep N-40641 on water, build the pad around the full 41,700-pound load, and it will serve as a long-term reservoir.
