The Norwesco 100 Gallon Portable Loaf Utility Tank is a black polyethylene loaf-style tank built for mobile water hauling on the farm, the job site, and the back of a utility trailer. Its low, wide loaf profile keeps the center of gravity down when the tank is full, which is exactly what you want bouncing down a field road. At 48 inches long, 20 inches wide, and 32 inches tall, it carries 100 gallons on a compact 20.0 x 48.0 inch footprint, so it drops into a truck bed or onto a skid without eating your whole deck.
Quick specs for load planning: 100 gallon capacity, 20 x 48 in footprint, 32 in tall, 834 lb full of water, 1,251 lb maximum rated contents at 1.5 specific gravity.
Will this 100 gallon utility tank work for my job?
Filled with water, this loaf tank carries roughly 834 pounds of contents, and the shell is rated to a 1.5 specific gravity, which means it is engineered for liquids up to about 1,251 pounds at full volume. That is real headroom: it covers field liquids heavier than water, up to 1.5 SG, so many farm fertilizer and chemical solutions in the 1.1 to 1.4 range fall inside its rating. The rule is simple before you fill it: confirm your specific liquid's specific gravity is at or below 1.5, and verify your fitting and gasket materials suit that liquid. Run your volume and weight numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you decide between a single 100 gallon unit and a pair of smaller tanks.
Mounting and the mistake to avoid
The most common mistake with a portable loaf tank is treating it like a stationary storage tank. It is not. A loaf tank is meant to travel, and it needs continuous, full-length support beneath the flat bottom plus banding or straps over the top so it cannot shift, walk, or chafe in transit. Plan your tie-downs and trailer deck around the full load of up to 1,251 pounds, not the dry weight of the tank, and do not suspend it on bearers with gaps or rely on the fittings to hold it in place. See the technical drawing on this page to confirm the molded-in fill opening and outlet locations before you plumb it. If you are running this behind a farm fleet truck, read our guide on Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption so you know where your DOT classification lands.
Setting it on a pad or skid
If this tank lives in one spot between hauls, give it a flat, level, fully supporting base. For a permanent above-ground pad, our guide on concrete pad sizing under the ACI 360R-10 framework covers how to size and finish the slab so the tank bottom stays fully bedded. If you are cross-shopping a larger form factor, the Norwesco Doorway Tank Sizing Guide walks the 100 to 1000 gallon range by application for the doorway style.
