The Norwesco 9000 Gallon HDPE Vertical Liquid Storage Tank (SKU N-43620) is a large polyethylene reservoir holding 9,000 gallons in a 141-inch-diameter footprint, standing 146 in (12.2 ft) tall. It carries a 1.9 specific gravity rating - the high end for polyethylene storage - which is what lets this Norwesco vertical tank serve heavy bulk-water duty. If you are sizing a reservoir for rural fire protection, irrigation supply, bulk-water storage, or process makeup, this is a tank built to hold a serious column of liquid.
Will it work for your site?
Filled with water, this tank carries a full-water weight of 75,060 lb, and its 1.9 SG rating allows a maximum rated contents weight of 142,614 lb. That headroom is a real fact to work with: the tank is rated to roughly 1.9 specific gravity, nearly double water's density, so it has structural margin for denser bulk liquids - just never exceed 142,614 lb total contents weight. Those numbers also drive two decisions before you order. First, the pad: a 141-inch-diameter footprint loaded to this weight needs an engineered, level concrete base sized to spread the load - the ACI 360R-10 concrete pad sizing framework walks through how to do this within the ACI 318 boundary. Second, the column height: at 146 in tall, the static pressure at the lower wall is significant. To confirm the tank suits your capacity target, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before committing.
The mistake to avoid on a tank this tall
Don't treat a 9,000-gallon vertical tank like a small utility tank. Fitting, vent, and overflow locations are not standardized on this listing, so confirm the outlet and manhole layout against the technical drawing on this page and your own install before setting anchors, and plan those penetrations for the full 75,060 lb water load. There's also a less obvious failure mode on a tall column: premature wall problems rarely start where you inspect them. The vapor-saturated headspace above the liquid line is where HDPE wall thinning can originate, and a liquid-side inspection misses it entirely - the headspace wall-thickness field guide covers that mechanism and the ASTM D1998 sizing logic behind it. For a full walk-through of this size class, see the 9000 Gallon Vertical Liquid Storage Tank buyer's guide.
Fire-water and rural reservoir service
A 9,000-gallon vertical Norwesco storage tank is a common building block in private fire-protection reservoirs, where stored-water volume and freeze protection both have to be engineered for the site. If that is your application, the fire-water reservoir design guide covers NFPA 22 sizing discipline, where polyethylene tanks fit in the private fire-protection stack, and freeze-protection engineering for cold-climate service.
This Norwesco vertical storage tank ships LTL freight from the Norwesco plant in St. Bonifacius, Minnesota, quoted live to your ZIP - get an exact number on the Freight Cost Estimator or call 866-418-1777. Plan for the size: an empty tank of this 141-inch footprint still requires crane or heavy-equipment offload, and full operating weight reaches 75,060 lb on water (up to 142,614 lb at max rated contents), so arrange delivery access and offloading equipment in advance. Our team can help you coordinate the details before you order.
