The Norwesco 100 Gallon Portable Loaf Utility Tank in White is a low-slung polyethylene utility tank shaped to ride in a pickup bed or on a trailer for mobile water hauling. It holds 100 gallons in a 27 by 41 inch footprint and stands just 30 inches tall, so the 41 by 27 inch base drops in between most truck-bed wheel wells and the 30 inch height clears most bed rails. Molded in white polyethylene with a 1.5 specific gravity rating, it is built for water and water-density liquids in farm, fleet, and job-site service.
Will it work for your haul?
Filled with water, this tank carries roughly 834 pounds of contents riding low in the loaf shape, and its 1.5 specific gravity rating means the wall is rated to hold up to about 1,251 pounds of liquid at maximum density. That headroom matters: a 1.5 SG wall carries denser loads than a water-only tank rated 1.0 to 1.1 SG, and most agricultural and utility liquids fall at or under 1.5 specific gravity. The weight also matters more than the gallon number when you choose a trailer, a pickup bed, or a skid, so plan your tie-downs and axle rating around the loaded weight, not the empty tank. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide to confirm the loaded weight fits your platform before you buy.
Fittings and lid
This tank ships with a single 8 inch threaded top opening for fill and access, the only molded fitting shown on the technical drawing on this page. There is no molded bottom outlet or vent, so if you need a drain, a bulkhead outlet, or plumbing, plan on adding it in the field with a lid and bulkhead or gasket kit sized to your hose. Review the technical drawing for the exact opening callout and placement so your fill hose and any added fittings match what the tank ships with.
Loaf tank sizing and DOT considerations
The right portable loaf tank depends on how much water you move per trip and what your vehicle can legally and safely carry. For fleet and agricultural use, our guide to Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption walks through DOT classification for farm fleet use. If this tank will instead sit as a stationary reservoir, the concrete pad sizing guide covers the ACI 360R-10 framework for a level, supported base.
