The Norwesco 20-gallon portable utility tank gives you a compact, white polyethylene reservoir for water hauling, spot spraying, and small-batch transfer where a full loaf or vertical tank is more than the job needs. At 34" tall on an 11" x 15" flat-bottom footprint, it sets upright on a truck bed, trailer, or skid and stays put in tight space. The white resin lets you read your fill level at a glance, and the flat bottom means no stand or cradle to build before you put this Norwesco white utility tank to work.
Will this tank work for your job
This is a 20-gallon Norwesco utility tank molded from polyethylene with a 1.5 specific gravity rating, so it carries water and water-density liquids without de-rating the wall. Filled with water, the contents weigh about 167 lb, and the tank is rated to hold up to 250 lb of contents. Here is the number that matters most: at 20 gallons of 1.5-density liquid the math works out to roughly 250 lb — exactly the rated maximum. That means the 1.5 SG rating is fully consumed at full volume, with zero weight margin left for anything denser. You cannot exceed 1.5 SG at a full fill, so size your liquid to stay at or under that ceiling. The flat 11.0 x 15.0 footprint and 34" height make it easy to strap down, but plan your mounting so a full tank rides low and centered rather than top-heavy on a moving vehicle. If you are not sure this size matches your draw-down or refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you buy.
What to check before you order
The most common mistake on a small utility tank like this is treating the 1.5 SG rating as a license to carry anything. The rating governs liquid density and total contents weight — it is not a chemical-compatibility approval. For plain water, hauled water, and general utility use it is exactly the right tank; for anything beyond water, verify compatibility separately and stay inside the 250 lb contents limit. Fittings vary by configuration, so confirm outlet, fill-port size, placement, and any gasket spec with us at 866-418-1777 before you plumb anything to this 20 gallon Norwesco tank — that detail drives how you mount and drain. If you are spec'ing this for a farm or fleet portable-water role, our guide on Norwesco portable utility tanks and the 49 CFR 173.5 agricultural exemption walks through the DOT classification questions that apply to portable farm tanks.
