The Norwesco 200 Gallon Portable Flat Bottom Utility Tank (SKU N-42347) is a white polyethylene tank built for hauling and dispensing water and field liquids where you need a stable, low-profile footprint. It holds 200 gallons, stands 36 inches tall, and sits on a 36 x 48 inch flat base, so it loads onto a truck bed, trailer, or skid and rides level without a cradle. Norwesco molds it with a 1.5 specific gravity rating, which means the wall is built to carry liquids up to 1.5 times the weight of water, and the tank ships from whichever Norwesco plant is closest to you.
Will this 200 gallon utility tank work for your setup?
Filled with water, this tank carries 1,668 pounds of contents, and its 1.5 SG wall is rated to hold up to 2,502 pounds of liquid at full capacity, which works out to roughly 12.5 pounds per gallon. That rating is what makes the difference: it suits water plus heavier field liquids, not just plain water, and the loaded weight matters far more than the gallon number when you plan your trailer rating, tie-downs, and any pad or deck. Both figures are contents weight only; add the empty tank weight, shown on the technical drawing, to size your transport and support correctly. At 1,668 pounds of water (2,502 pounds maximum rated contents), "portable" here means trailer- or truck-bed transport rated for that load, not a hand-carry move. If you are still choosing between sizes for a tank, water reservoir, or fleet application, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a footprint.
Fittings and access
The top carries a thread for an 8-inch lid for filling and access. As drawn, this is the only documented opening: the technical drawing on this page shows a single 8-inch threaded lid and does not document a bottom drain outlet, so plan to dispense by pump or siphon through the top unless you confirm an outlet option with us first. Before you order accessories, confirm the 8-inch lid thread matches the fill fitting you intend to use, and review the technical drawing on this page for the exact fitting layout and dimensions.
Mounting, hauling, and weight planning
The 36 x 48 inch flat bottom is the reason buyers choose this Norwesco utility tank over a round vertical: the larger footprint and low 36-inch height keep the center of gravity down for transport and reduce sloshing when the tank is partly full. If you are running this on a farm fleet, the guide to 49 CFR 1735 agricultural exemptions and DOT classification covers how portable utility tanks are treated in transport. For permanent above-ground placement, size your support using our concrete pad sizing guide built on the ACI 360R-10 framework. For rural fire-water storage, see our NFPA 22 fire-water reservoir design notes, and for greywater, rainwater, or condensate capture our water reuse tank topology guide.
The mistake to avoid
The most common error on a portable tank this size is under-rating the support and the haul. A full 200 gallons is 1,668 pounds of water before you add the tank weight, and the wall itself is rated to a 2,502-pound contents maximum. Build your deck, hitch, and tie-down plan around those loaded figures plus the empty shell weight from the drawing, and confirm your fill and access plan around the single 8-inch lid thread before you order.
