The 2500 Gallon Norwesco Vertical Water Storage Tank holds 2,500 gallons of water in a 102-inch diameter polyethylene body standing 79 inches tall. It is built for rural water supply, fire-water reservoir duty, irrigation drawdown, rainwater aggregation, and bulk agricultural or municipal storage where you need serious volume on a single footprint. This is a wide, low-slung vertical tank: a 102-inch diameter base under a 79-inch overall height keeps its center of gravity down when full, which matters on graded pads and in regions that see real wind load.
Will it work for your site?
Filled to capacity this tank carries 20,850 pounds of water, and that figure is also the maximum rated contents weight - this body is engineered around the weight of water, and that is the ceiling. Spread across a 102-inch-diameter footprint (about 56.7 square feet), that works out to roughly 370 pounds per square foot, so spec your slab or compacted pad in psf, not just gross tonnage, and rate it across the full circle. The polyethylene wall is rated to a specific gravity of 1.0, which matches plain water exactly. Use the Tank Sizing Calculator with your daily demand and refill interval - 2,500 gallons usable assumes full drawdown - and check the Tank Sizing Guide before you commit. If you are designing a private fire-protection reservoir, our guide on fire-water reservoir tank design and NFPA 22 sizing covers how a polyethylene tank fits the stack and how to handle freeze protection in cold climates.
Footprint vs. height: two 2500-gallon options
We list this 2,500-gallon black tank in two shapes, and the choice comes down to your pad. This one is 102-inch diameter by 79-inch height - the wider, lower-CG option that needs a 102-inch pad. The sibling is 98-inch diameter by 86-inch height - a smaller footprint but taller overall. If pad area is tight, the taller tank saves ground; if overhead clearance or stability is the concern, the wide one wins. See the complete buyer's guide for the 102 x 79 tank and the guide for the 98 x 86 version to weigh the trade-off.
Fittings and the mistake to avoid
This listing does not specify a fitting, outlet, or gasket schedule, so do not assume any are included or located where your manifold expects them. Confirm port sizes, outlet positions, and gasket material against the technical drawing on this page or by phone before you plumb anything. The bigger error on a tank this size is treating the 1.0 specific-gravity rating as a suggestion - it is a hard limit for water only. Anything denser than plain water exceeds what the wall and floor were molded to carry at this diameter, and on a 2,500-gallon body that mistake is measured in tons. If your project blends or stages multiple water sources, our guide on industrial water reuse tank topology covers grey-water, rainwater, and HVAC condensate aggregation in quality-banded storage trains.
This vertical water storage tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant - Hanford, CA; Merced, CA; or Washougal, WA. All three origins are western, so a West-coast pad is a short haul and an East-coast site should plan on a longer LTL run; the Freight Cost Estimator shows which origin applies to your ZIP. Get your estimate there or call 866-418-1777 to lock in delivery. Listed price is the tank only; LTL freight is quoted separately to your ZIP.
