The Norwesco 2500 Gallon Vertical Water Tank is a 96-inch-diameter polyethylene vertical built for sizable above-ground bulk water storage on farms, fire-reserve sites, rural homesteads, and industrial water-reuse trains. It holds 2,500 gallons in a round 96-inch (8 ft) diameter body that stands 96 inches (8 ft) tall, and it ships in green polyethylene. This is a water-service tank rated at 1.0 specific gravity, meaning it is built to store water and other contents at or below the density of water - not heavier chemical solutions. If you are checking site clearance, overhead height, or gate width, plan around an 8-foot circle and 8 feet of vertical room.
Will it work for your site?
Match the tank to two numbers: the contents and the load it puts on your pad. Filled to capacity with water, this 2500 gallon Norwesco tank carries roughly 20,850 pounds - which is also its maximum rated contents weight at the 1.0 specific gravity rating. That works out to 8.34 pounds per gallon, exactly water density, so you can compute any partial-fill load directly: gallons on hand times 8.34 is the weight bearing on your pad at that moment. The footprint that spreads that load is the 96-inch (8 ft) diameter base, so your pad needs to be at least 8 feet across and fully under the entire base. An above-ground polyethylene tank wants a continuously supported, flat, level bearing surface under the whole bottom - not point supports or a pad smaller than the tank. Confirm your pad is sized and level for a tank this size before delivery. Our concrete pad sizing guide walks the ACI 360R-10 framework for getting that base right, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 2,500 gallons is the right capacity before you commit. Refer to the technical drawing on this page for fitting placement and overall dimensions.
The mistake to avoid: the 1.0 specific gravity rating
This tank is rated for 1.0 specific gravity - water. That rating is the single most common place buyers go wrong on a vertical this size. The concrete trigger is simple: anything heavier than 8.34 pounds per gallon means a specific gravity above 1.0, and a 1.0-rated wall is not built for that sustained load. Denser contents also weigh more than the 20,850-pound full-water figure, compounding the load. Keep this one in water service - irrigation, rainwater and grey-water reuse, fire reserve, and similar at-or-below-water-density contents. If your application is a denser solution, you need a higher specific-gravity tank, not this one; call us at 866-418-1777 before you order and we will point you to the right rating.
Common uses
At 2,500 gallons this Norwesco vertical sits in a useful middle band - large enough to be a real reserve, compact enough for a single 8-foot pad. It is a workable fire-water reservoir for rural and remote sites where you are building a private fire-protection stack; see our fire-water reservoir design guide for NFPA 22 sizing discipline and cold-climate freeze protection. It also fits cleanly into an industrial water-reuse topology aggregating grey-water, rainwater, and HVAC condensate into quality-banded storage. On any new install, run a controlled water fill and watch the base - our hydrostatic test methodology covers the fill discipline, pad-settlement monitoring, and fitting leak-detection that should happen before this Norwesco tank goes into service.
