A 1000 gallon black flat bottom utility tank for low decks and dark storage
The Norwesco 1000 gallon flat bottom utility tank in black, part number 45736, is a polyethylene tank 134 inches long, 90 inches wide and 21 inches tall, weighing 250 lb empty. It carries a thousand gallons with almost no height, which is what you want on a flatbed, a trailer deck, a low rack or inside a building with a normal door. The black wall keeps light out of the contents, which slows algae in stored water and protects light sensitive liquids. It comes with an 8 inch lid on top. The tank is rated for liquids up to 1.5 specific gravity, which covers water, most liquid fertilizers and many common chemicals, with a service limit of 120 F. The resin is FDA compliant per Norwesco. A full load of water weighs 8340 lb.

Where it goes
Hauling water is the main job: dust control, stock water, a nurse tank behind a sprayer, or a reserve on a truck that also has to carry equipment. At 134 by 90 inches the footprint takes most of a flatbed or tandem trailer, so measure the deck and the gap between wheel wells before you order. The 21 inch height is also why these tanks end up indoors as holding or process tanks, in places a round tank cannot reach. Black is the better pick for water that will sit for weeks, and for anything that sunlight degrades. Our guide to portable utility tanks on farm vehicles covers the agricultural exemption and how these tanks are classified on the road, and the doorway tank sizing guide helps when the tank has to pass through an opening.
Full, you are carrying 8340 lb of water plus the 250 lb tank, and more with fertilizer. The vehicle payload or the floor is the limit, not the tank. If it is going on a slab, our note on concrete pad sizing for polyethylene tanks has the method. For the volume itself, use the tank sizing calculator and tank sizing guide.
What to check before you buy
- The surface under it. A flat bottom tank wants a flat, continuous surface under the whole footprint. On a trailer that means solid decking. A tank bridging open cross members flexes at every fill.
- The lid. One 8 inch lid on top for filling and venting. It is not a manway; clean the tank through the lid with a wand.
- The outlet. No outlet fitting is listed on this tank. Tell us where you want the drain and what size, and we confirm what ships on the tank and what to add.
- The liquid. Polyethylene handles water, most fertilizers and many common chemicals. Heavier than 1.5 times water, or hotter than 120 F, needs a different tank.
- Tie-down. Strap over the body, never across the lid, with enough straps that a half full tank cannot walk sideways.
