The Norwesco 120 Gallon HD Vertical Storage Tank is a 54-inch-tall vertical tank on a compact 28 x 28 inch footprint, molded by Norwesco in high-density linear polyethylene and finished in white. It carries a specific gravity rating of 1.9, which means it is rated to hold liquids up to 1.9 times the density of water, so it covers plain water with room to spare and also handles heavier solutions up to its maximum rated contents weight. The resin is FDA-approved, making this tank suitable for potable water storage and general liquid storage.
Will this tank work for your job?
Filled with water, this Norwesco vertical storage tank holds about 120 gallons at roughly 1,001 pounds, and the 1.9 SG rating corresponds to a maximum rated contents weight of about 1,902 pounds. That density headroom is worth weighing if you are comparing this against a 1.5-SG tank for anything heavier than water. The top carries a single 8 3/8-inch molded opening sized for a standard 8-inch lid, giving you a clean fill point and access for cleaning. The pack does not confirm a lid or gasket ships with the tank, so verify lid and gasket inclusion at order. For exact port placement and wall geometry, see the technical drawing on this page. If you are still narrowing capacity against your draw rate or pump cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Siting and support
At 1,902 pounds at its maximum rated contents weight on a 28 x 28 inch footprint, this tank concentrates real weight over a small area, so it needs a flat, fully supporting base. A poured pad is the right call for permanent installs; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab carries the load without cracking. The compact 28-inch footprint makes this size practical where floor space is tight, and it palletizes tightly for freight. Whether you are setting it up as a buffer in an industrial water reuse train or as fixed liquid storage, the vertical profile stacks capacity upward rather than out.
Freight: how it ships
This tank ships LTL freight from the Fairfield, TX plant, and freight is quoted live to your ZIP code rather than rolled into the list price. Get an exact number before you buy with our Freight Cost Estimator, or call 866-418-1777 to set up the shipment. One mistake to avoid: do not under-size your footing or set this tank on uneven gravel. A vertical storage tank loaded near its 1,902-pound maximum rated weight will flex and stress at the base if it is not evenly supported, and even support is critical to long service life.
