The Norwesco 110 Gallon Portable Flat Bottom Utility Tank is a black polyethylene unit measuring 48" long by 35" wide by 18" tall, built for hauling and stationary utility duty where a low, stable profile matters more than vertical height. The black resin blocks light to slow algae growth, and the flat-bottom design sits directly on a truck bed, trailer deck, skid, or concrete pad without a stand. This is the kind of low-slung Norwesco utility tank fleets reach for when they need water or a compatible liquid on the move.
Will it work for your job?
At 110 gallons, a full load of water weighs roughly 917 lbs of contents in the tank. The shell carries a 1.5 specific-gravity rating, so it is engineered to hold liquids up to 1.5 times the weight of water - a maximum rated contents weight near 1,376 lbs. Both of those are contents figures and do not include the tank's own shell weight, so when you size a trailer or plan your tie-downs, treat them as the liquid load on top of the empty tank, not the total. That 1.5 SG headroom is why this tank handles denser utility liquids, not just water. The 35" x 48" footprint spreads the load across a wide base, which keeps it planted in transit. If you are weighing this against other sizes, run your volume and liquid weight through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Fittings and stationary mounting
Fitting size and thread are not specified in our data for this model, so see the technical drawing on this page for fitting locations and exact dimensions, and confirm the thread against that drawing or call us before you order gaskets or adapters - we will not guess an outlet size for you. If you are setting this tank in a fixed location rather than hauling it, a flat-bottom poly tank wants a flat, fully supported base; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for doing that pad right.
How does it ship?
This tank ships LTL freight, palletized, with the rate quoted live to your ZIP code. Norwesco molds this model at three plants - Fairfield, TX; Hanford, CA; and Sheldon, IA - so your freight cost and lead time depend on which of those is nearest you. Pull a number before you buy with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you from the closest plant.
The mistake to avoid
The most common error on portable utility tanks is treating the 1.5 SG rating as permission to mount and drive without securing the load. A 110-gallon tank under a moving liquid load shifts hard - strap it down across the full footprint and never run it partially filled on rough roads. The flat black shell also reads as a general-purpose vessel, so confirm your specific liquid is compatible with HDPE and stays within the 1.5 SG ceiling before filling; the 1.5 SG rating is the ceiling for this tank, not a starting point. If you are running this on a farm fleet, the DOT classification details for portable utility tanks are worth reading in our guide on the 49 CFR 173.5 agricultural exemption.
