The Norwesco 150 Gallon Flat Bottom Tank with Slosh Guard (SKU N-43296) is a white, flat-bottom polyethylene portable tank rated to a 1.5 specific gravity. It stands 28.375 inches tall on a 36 x 48 inch footprint, so it drops onto a standard pickup bed, trailer deck, or skid without overhanging the rails. The integrated slosh guard is the reason this Norwesco tank earns its keep on a moving vehicle: it dampens the wave action that would otherwise shove a partially full tank around in transit. If you have been searching for a 150 gallon flat bottom tank that hauls reliably, this is the portable Norwesco built for the job.
Will it work for your job
Capacity is 150 gallons in a white polyethylene shell. Full of water, the tank and contents weigh about 1,251 pounds; at the tank's maximum 1.5 specific gravity rating, rated contents weigh up to 1,876 pounds. Use those two numbers to spec your trailer, truck bed, and tie-downs before you fill it. The 36 x 48 inch footprint and 28.375 inch height keep the center of gravity low, which is exactly what you want under load on the road. If you are not sure 150 gallons is the right size for your water volume and haul distance, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide first.
Spec it right the first time
The 1.5 specific gravity rating is a ceiling, not a license to fill with anything. It means the tank is built to carry contents up to 1.5 times the weight of water. At plain water (SG 1.0) the loaded tank and contents run about 1,251 pounds; at the full 1.5 ceiling that climbs to roughly 1,876 pounds. If your fluid's specific gravity exceeds 1.5, this tank is not rated for it, so call 866-418-1777 and we will spec a higher-rated tank instead. The common mistake on a portable tank is loading it on a deck that cannot carry roughly 1,900 pounds at full rated weight, or skipping tie-downs and letting an under-filled tank slosh, which is the very thing the slosh guard is engineered to control. Because fitting and outlet placement varies by build, confirm the outlet location, fitting thread size, and gasket type from the technical drawing on this page before you order bulkhead hardware, and call 866-418-1777 to verify the exact fitting spec for your N-43296 before you plumb it.
Sizing and footprint
Mounted dimensions are 36 inches wide by 48 inches long by 28.375 inches tall. Lay that out against your bed or trailer deck before ordering so the tank sits flat and fully supported. A flat-bottom tank needs continuous support across the whole base, not just at the corners. Fully loaded at the 1.5 ceiling, roughly 1,876 pounds sits on a 36 x 48 inch (12 square foot) base, about 156 pounds per square foot, so set it on a flat, continuous surface and do not bridge it across rails or perch it on corner blocks. For permanent above-ground placement on a pad rather than a vehicle, the concrete pad sizing guide walks through the support framework, and the portable utility tank classification guide covers the DOT and agricultural-exemption side of farm fleet hauling.
