The Norwesco 2500 gallon vertical water storage tank (part #40631) is a black polyethylene tank measuring 95" in diameter and 91" tall, built for bulk water storage where you need real volume in a compact round footprint. The black resin blocks light to discourage algae growth, which makes it a practical choice for rainwater collection, fire-water reservoirs, irrigation, and general water storage. With a 2500 gallon working capacity and a polyethylene wall rated to a specific gravity of 1.0, this is a vertical storage tank engineered for water and water-density liquids.
Will it work for your site?
The numbers that drive placement and plumbing: 95-inch diameter, 91-inch height, and a 95-inch-diameter footprint. Filled to capacity with water, the tank and its contents weigh approximately 20,850 lbs, which is also the maximum rated contents weight. Because more than ten tons of water sits on the base, that load drives your pad design - a fully supported, level concrete or compacted base sized to the full 95-inch diameter is essential, since polyethylene tanks rely on continuous bottom support rather than spanning gaps. Plan to set the tank in its final position empty and fill it on the pad; at ~20,850 lbs full you cannot relocate a filled tank. Run your fill volume and pad dimensions through the Tank Sizing Calculator, and if you are matching this to a fire-water or storage duty, the Tank Sizing Guide walks through capacity and footprint planning. See the technical drawing on this page for the fitting and outlet layout - confirm fitting size and placement there, since they are shown on the drawing rather than assumed - before you finalize plumbing.
Service limit: this is a 1.0 specific gravity water tank
The polyethylene wall on this tank is rated to a specific gravity of 1.0, so it is built for water and water-density liquids only. For fertilizer, brine, or chemical service heavier than water (above 1.0 SG), you need a tank rated to a higher specific gravity - do not fill this one with a heavier liquid. If you are unsure where your liquid falls, the Tank Sizing Guide covers how to match rating to contents, or call our team at 866-418-1777 and we will point you to the right tank.
Freight: how it ships
At roughly 20,850 lbs full and 95 inches across empty, this is an LTL freight item, not a parcel-ship product. Norwesco produces this tank at nine plants - Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Merced, CA; Owego, NY; Shawnee, OK; Tooele, UT; and Washougal, WA - so your tank ships from the nearest of those plants to your delivery ZIP, which keeps LTL distance and cost down whether you are on the coasts or in the central states. Before delivery, confirm the 95-inch-wide tank can clear the gate or path to the pad and that the site has overhead clearance to offload a tank just over 7.5 feet tall.

The mistake to avoid
The most common error on a tank this size is the foundation. A 2500 gallon vertical tank carrying over ten tons of water will crack or deform if it sits on an uneven, undersized, or partially supported base. Build a level pad that supports the entire 95-inch diameter, and never set the tank on blocks or a ring that leaves the center unsupported. The second pitfall is mismatching the liquid: this is a 1.0 specific gravity water tank, so confirm your stored liquid is water or water-weight before filling. For deeper planning on reservoir and reuse applications, our fire-water reservoir design guide and industrial water reuse topology guide cover sizing and storage-train design in detail.
