Norwesco 200-40"W LOAF NATURAL

The Norwesco 200-40"W Loaf is a portable utility water tank built for farm and fleet use where a low, stable profile matters more than height. At 31" tall on a 48" x 40" footprint, this natural white polyethylene tank holds 200 gallons and rides low enough to sit in a truck bed or on a skid without turning into a rollover risk. The natural white translucent wall lets you eyeball the water level at a glance, and the 8" lid gives you a wide opening for filling, cleaning, and inspection. Empty, it weighs about 80 lb, so one or two people can reposition it when it's drained.

Will it work for your job?

This is a water and general-utility tank, FDA-approved polyethylene, rated to a maximum contents temperature of 120 F / 48 C. The wall is engineered to a 1.5 specific gravity rating, which is why it handles water and comparably heavy liquids without deforming. Run the numbers before you load it: 200 gallons of water weighs about 1,668 lb, and with the 80-lb shell a filled tank rides at roughly 1,748 lb — that's the number your pad, bed, or trailer has to be rated for. The structural ceiling is 2,502 lb of contents, so measured contents-to-contents you have about 834 lb of headroom above plain water. That headroom is a weight ceiling, not a volume ceiling: don't fill past the 200-gallon mark. If you're sizing across a fleet or a job, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to your haul-weight limits.

What the 1.5 SG rating actually buys you

That 834 lb of contents headroom is real capability, not just margin. Because the wall is rated to 1.5 specific gravity, you can run liquids denser than water — brines, light slurries, and heavier water solutions up to about 1.5 SG — as long as the volume stays at or below 200 gallons and the liquid is chemically compatible with polyethylene. The limit you hit first is weight, so a denser liquid means a lower fill line. Keep the fill under 120 F, too: on a translucent tank sitting in an open truck bed or on a spray rig, sun-heated or hot-fill water can climb, and 120 F / 48 C is the stated wall rating.

The loaf shape, mounting, and fittings

The loaf profile — wide, low, and flat-bottomed — is what makes this a favorite for pickup beds, spray rigs, and portable water supply. Because it carries its load low, it stays planted in transit better than a tall vertical tank of the same capacity. Strap it down across the top and support the full flat bottom; never let it hang unsupported or ride on point loads. This listing ships with the 8" lid — the only opening in its spec set; outlet and bulkhead fittings are not specified for this SKU, so call 866-418-1777 to confirm fitting options before you plumb it. See the technical drawing on this page for exact height, width, and lid placement before you build a rack or cut a bed liner. For farm-fleet operators, our guide on Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption covers where DOT classification does and doesn't apply to farm use.

The mistake to avoid

The 1.5 specific-gravity rating is a structural weight rating, not a chemical-service license. This tank is FDA-approved poly built for water and light utility duty — nothing in its spec set covers chemical resistance. If your liquid is chemically active, stop and confirm poly compatibility and the right resin before you fill. For water and compatible water solutions within the weight ceiling, it's exactly what it's built for.
