The Norwesco 5025-gallon horizontal leg tank is built for large-volume liquid transport and field nurse-tank duty, molded from white polyethylene. The rounded horizontal body sits on integral molded legs, keeping a full load low and stable whether the tank rides a trailer chassis or sits on a saddle skid in the yard. Plan the supporting structure and tie-downs around a fully loaded tank, not an empty shell.
Will it work for your job?
Capacity is 5,025 gallons in a polyethylene horizontal leg-tank format. The number that drives every mounting and hauling decision is loaded weight: filled with water, this tank carries 41,908 pounds of liquid, and that figure climbs with any product heavier than water. Fitting and outlet configuration varies by build, so call 866-418-1777 to confirm the fill, outlet, and vent layout before you spec your plumbing and cradle. Before you commit to a trailer or transport frame, run your numbers through the Tank Sizing Calculator and review the Tank Sizing Guide so the axle rating, frame, and cradle match the loaded weight. See the technical drawing on this page for the body profile and leg layout.
The mistake to avoid
The classic error on a tank this size is treating it like a stationary storage vessel. A horizontal leg tank is a haul-and-transport design: a 41,908-pound load shifting in a partially filled tank changes how a trailer behaves on the road, so plan for surge, secure the tank to a continuous cradle that supports the full length of the body, and never exceed the loaded-weight rating of your chassis. The water load alone is already near a legal-load ceiling for many trailers — a fertilizer or brine product heavier than water pushes that figure up proportionally, so a 1.5 specific-gravity liquid would put roughly 62,900 pounds of product in the tank. Account for that in your weight math before the spreader ever leaves the yard. These fundamentals are covered in our guides on Norwesco applicator and leg tanks for fertilizer and portable utility tanks under the 49 CFR agricultural exemption.
Running blended fertilizer?
At this volume, stratification and density-driven salting-out are real operational risks, not footnotes — a blend that layers out in the tank sends the spreader off-spec before you notice. Read our fertilizer-blend tank stratification guide for the mixing protocol and field-verification methods that catch a stratified tank before your first load goes out.
