500 Gallon Portable Loaf Utility Tank in White

The Norwesco 500 Gallon Portable Loaf Utility Tank in white is a low-profile polyethylene tank built for mobile water hauling and utility transfer. Its loaf shape rides low on a trailer or truck bed, keeping the center of gravity down while you move 500 gallons of water across a field or between sites. This is the tank people search for as the Norwesco 500 gallon loaf tank, and it earns that reputation by staying stable and simple on the move.

Quick specs

Capacity 500 gallons / Brand Norwesco / Material polyethylene / Type Loaf Tank / Specific gravity rating 1.5 / Full-water contents load about 4,170 lb / Maximum rated contents about 6,255 lb. See the technical drawing on this page for the tank's footprint and profile.

Will it work for your job?

Full of water, this utility tank carries about 4,170 pounds of contents. Whatever holds it - trailer frame, cradle, or truck deck - has to support that load plus the tank itself. The polyethylene shell carries a 1.5 specific gravity rating, meaning it is structurally rated for contents up to 1.5 times the weight of water, or roughly 6,255 pounds at maximum rated density. If you haul anything heavier than plain water, size your axles and trailer to that 6,255 lb worst case, not the 4,170 lb water figure. To match this 500 gallon capacity to your flow and fill schedule, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. One note before you order: fitting and outlet configuration is not published for this model, so confirm bung and outlet size and gasket material for your pump and hose by calling 866-418-1777.

Mounting and a mistake to avoid

Because loaf tanks are designed to be moved when full, how you seat and strap the tank matters as much as the tank itself. Support the full length of the base and strap over engineered tie-down points, never over bare shell. The biggest error with a portable tank is treating a partial load as harmless - water sloshing in a half-full loaf tank shifts weight hard under braking and cornering, so fill fully or slow down. The second mistake is reading the 1.5 SG rating as a chemical clearance; it covers structural weight only, not chemical resistance, so keep this white tank on water and utility service. If you run this as a farm or fleet utility tank on public roads, review our guide on Norwesco loaf-style portable utility tanks and the agricultural exemption to understand how the tank is classified for farm fleet use.
