The 9000 Gallon Vertical Liquid Storage Tank from Norwesco is a high-volume bulk vertical tank built for sites where footprint efficiency matters as much as raw capacity. Molded from polyethylene, it stands 146 inches tall on a 141 x 141 inch square footprint and holds 9,000 gallons in a single tank. If you are sizing a fire-water reservoir, a rural water supply, or an industrial reuse train, this is one of the most compact ways to stage that much liquid on a tight pad.
Will it work for your application
This Norwesco vertical storage tank carries a 1.5 specific gravity rating, the highest standard rating offered, which means it is engineered to hold contents up to 1.5 times the density of water. Filled with water alone, the contents weigh roughly 75,060 pounds; at the full 1.5 SG rating, the tank is rated to carry up to 112,590 pounds of contents. For a water buyer that 1.5 build is genuine over-spec: water is SG 1.0, so you are carrying a 50 percent density margin as a conservative safety factor, and you are not boxed in if the service fluid ever changes to something denser. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 9,000 gallons is the right volume before you commit to a tank this large.
Layout, fittings, and the pad
At 141 inches wide and deep with a 146-inch overall height, this vertical tank packs 9,000 gallons into a square footprint, which is exactly why vertical storage tanks win on tight sites versus sprawling horizontal designs. The technical drawing on this page shows the overall geometry so you can plan plumbing connections and clearances before the tank arrives. One honest note: the fitting and gasket configuration is not listed on this page, so confirm inlet, outlet, vent, and manway sizes and gasket material against the technical drawing or by calling 866-418-1777 before you finalize any plumbing. Equally important, size your pad and anchoring off the actual loaded weight, not the empty shell: our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks. If the service fluid is denser than water, size the pad and subgrade off the 1.5 SG figure of 112,590 pounds, never the 75,060-pound water number.
Common applications
This size sits in the sweet spot for private fire protection storage, where a single reservoir tank serves a rural or remote site; our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. It also fits industrial water reuse work, where grey-water, rainwater, and HVAC condensate are aggregated into quality-banded storage; our industrial water reuse tank topology guide details treatment-stage sequencing.

Freight and ordering
This tank ships LTL freight from Norwesco's plant in St. Bonifacius, Minnesota, quoted live to your ZIP code. At roughly 12 feet tall on a 12-foot-square footprint, a 9,000-gallon vertical tank is an over-height, oversized load, so the height and footprint drive both the truck and the offload equipment you will need on site. The tank itself ships empty, but confirm your delivery site and any positioning equipment can handle a tank of this size before it lands. Freight is handled and quoted separately from the tank price, so run your delivery ZIP through the Freight Cost Estimator for a live quote, or call us at 866-418-1777 and we will line up the carrier, confirm offload requirements, and walk you through delivery for a tank this size.
