The Norwesco 9000 Gallon Black Vertical Storage Tank is built for serious bulk water storage on rural, agricultural, fire-protection, and industrial sites. This is a 9,000-gallon polyethylene vertical tank in black, standing 146 inches tall on a roughly 141-inch diameter footprint, with a specific gravity rating of 1.5. If you are scaling up a private water reservoir, an irrigation supply, or a long-haul reuse system, this is the kind of high-capacity Norwesco vertical storage tank that anchors the whole setup.
Will it work for your site?
Start with the capacity math, because at this size it dominates everything else. Filled to 9,000 gallons of water, the tank carries roughly 75,060 pounds of contents, and at its full 1.5 specific gravity rating the maximum rated contents weight is 112,590 pounds. That is 37,530 pounds of density headroom above plain water, and it is the single most decision-relevant number here: engineers should size the pad and ringwall to the rated load, not the water load. The footprint is a clean cylinder at roughly 141-inch diameter (146 inches tall), so a lot of weight concentrates on a small area and the foundation matters as much as the tank. For above-ground installs, read our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide before you pour, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 9,000 gallons matches your draw-down and refill cycle. The black polyethylene wall also limits light penetration, which helps suppress algae growth in stored water compared with translucent tanks. See the technical drawing on this page for dimensional detail.
Sizing it into your system
A tank this large rarely stands alone. On rural and remote sites it often serves as the reservoir behind a private fire-protection stack; our guide on Fire-Water Reservoir Tank Design for Rural and Remote Sites walks through NFPA 22 sizing discipline and freeze protection for cold-climate service. If you are aggregating grey-water, rainwater, or HVAC condensate into a reuse train, our Industrial Water Reuse Tank Topology guide covers quality-banded storage trains, and for harvesting setups the first-flush diverter sizing guide shows how to keep incoming water clean. Because no installed fittings are recorded for this configuration, confirm fitting and gasket sizes, materials, and placement at quote time rather than assuming a layout.
The mistake to avoid
The number one error on a tank this size is treating the specific gravity rating as a green light to store anything. The 1.5 rating describes the maximum density of liquid the tank wall can carry, not chemical compatibility. This is a water storage tank, and the smart move is to keep it on water and water-grade reuse duty, fire reservoir, and irrigation service unless you have verified the specific liquid against the polyethylene resin and the gasket and fitting materials you intend to install. The second mistake is under-building the foundation: 112,590 pounds of fully rated load on a roughly 141-inch-diameter footprint will punish a pad that was sized for a smaller tank.
This Norwesco vertical storage tank ships LTL freight from the Norwesco plant in St. Bonifacius, Minnesota, quoted live to your ZIP. LTL cost and transit scale hard with distance from Minnesota, so run your actual ZIP through our Freight Cost Estimator before you commit, or call us at 866-418-1777 to plan delivery and offloading, since you will need equipment on site to handle a tank this size.
