The Norwesco 1250 Gallon Black Vertical Storage Tank is a 1,250-gallon polyethylene vertical tank that stands 114 inches tall on a 60-inch (5 ft) round footprint, making it a practical bulk water store for fire-protection reservoirs, rural water supply, rainwater capture, and industrial reuse trains where vertical real estate is cheaper than ground area. The black resin blocks light penetration, which suppresses algae growth in stored water far better than a translucent tank, so this configuration suits long-dwell storage that sits for weeks between draws.
Will this tank work for your application?
Capacity is 1,250 gallons in a vertical storage tank measuring 114 in tall by 60 in diameter. It is molded from polyethylene and carries a 1.5 specific-gravity rating, which is structural headroom rather than a cue to store denser chemicals: this is a water-service tank, and the rating means the wall carries a full water load with a large margin. A full load of water weighs about 10,425 lb, while the wall is rated to carry contents up to 15,638 lb. Plan your pad and tie-downs around the filled weight, not the empty shell. If you are unsure whether 1,250 gallons matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Foundation, sizing, and freeze planning
Because this is a tall vertical tank on a relatively small base, the foundation matters more than people expect. A 114-inch column of water on a 60-inch footprint must sit on a continuous, flat, level pad that supports the entire bottom. The math a contractor needs is simple: about 10,425 lb of water spread over a 5-foot circle works out to roughly 530 lb per square foot of bearing pressure, so take that number to whoever pours your pad. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the framework. For fire-water reservoir duty, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse tank topology guide walks through quality-banded storage trains, and the first-flush diverter sizing guide helps you keep captured rainwater clean.
The mistake to avoid
The most common error on a tank this size is treating the empty shell weight as the design load. The contents govern: roughly 10,425 lb of water at full, against a wall rated for up to 15,638 lb. Don't undersize the pad or skip a level base, because an unevenly supported vertical tank concentrates stress at the bottom knuckle. And before you plumb it, verify outlet size, fitting type, and port heights with us at 866-418-1777 rather than assuming a layout, so your bulkhead and outlet connections land where you actually need them on this Norwesco vertical storage tank.
