The Norwesco 68-gallon flat-bottom utility tank gives you a compact, white polyethylene reservoir built for portable water hauling, transfer, and general-purpose storage where a low, stable footprint matters more than vertical height. It holds 68 gallons in a body that measures 42 inches long by 27 inches wide by 17 inches tall, so it slides into a truck bed, trailer deck, or skid platform and sits low enough to stay steady down a field road. The white tank lets you read the water level at a glance, and the flat bottom puts the full load flat on your deck instead of on a saddle or stand.
Will it work for your setup?
This is a polyethylene utility tank rated to a 1.5 specific gravity, which means the wall is built to carry contents up to 1.5 times the weight of water. Filled with water, the 68 gallons weighs about 567 pounds, and the tank is rated to carry up to 851 pounds of contents at its full 1.5 SG rating. That 1.5 SG is the ceiling for this tank: 851 pounds is the rated contents maximum, and a fluid heavier than 1.5 times water is out of spec for this body, so size your fill to stay under that number. Plan your deck, trailer, or mounting platform around the heavier of those weights and make sure the surface fully supports the 27-by-42-inch flat-bottom footprint, edge to edge, with no overhang.
The numbers at a glance:
- Footprint: 27 in x 42 in
- Height: 17 in
- Full water weight: 567 lb
- Max rated contents: 851 lb at 1.5 SG
If you are matching this tank to a load and want to check the full-weight math against your trailer or pad, the Tank Sizing Calculator and the Tank Sizing Guide walk you through it. For a poured base under an above-ground tank, the concrete pad sizing guide covers the ACI framework.
Fittings, mounting, and use
Confirm the outlet and fitting layout against the technical drawing on this page before you plumb the tank, so your bulkhead, valve, and hose run line up with what is actually molded into this body. Check that any gasket and bulkhead you fit are rated for the mechanical load and seated squarely on the drawing's molded boss. If you need the outlet size and bulkhead configuration verified before you buy, call 866-418-1777 and we will confirm it against the drawing and OEM data. As a portable flat-bottom utility tank, it is a natural fit for farm and fleet water transfer, sprayer fill, jobsite supply, and small fire-water or reservoir duty at remote sites. If you are running this Norwesco utility tank on a trailer or truck for agricultural use, the guide on 49 CFR 173.5 agricultural exemptions and DOT classification is worth reading before you hit the road. For rural fire protection planning, see the fire-water reservoir design guide, and for greywater or rainwater capture the water reuse topology guide covers quality-banded storage.
The mistake to avoid
The common error with a low, wide utility tank is supporting it like a stand-mounted tank. A flat-bottom Norwesco needs its entire base carried on a flat, level surface. Bridging the tank across rails, letting an edge overhang a deck, or setting it on a frame that only touches at the perimeter concentrates the load and stresses the bottom of the tank, especially as you approach the 851-pound rated contents weight. Set it flat, support it fully, and strap it for transport.
This tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant that stocks it. It is molded at seven plants — Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Shawnee, OK; Sheldon, IA; and St. Bonifacius, MN — so most regions have a nearby ship point, which keeps freight reasonable.
