The Norwesco 100 Gallon Flat Bottom Tank with Slosh Guard is a portable polyethylene utility tank built for moving and storing 100 gallons of water and water-based fluid on a truck bed, trailer, or skid. It carries a 1.5 specific-gravity rating, has a 26.75 x 42.5 inch footprint, and stands 27.75 inches tall, so it loads under most canopies and sits low for a stable center of gravity in transit. The molded slosh guard is the reason to pick this version over a plain portable tank: it dampens the wave action that builds inside a partially filled tank on the road, so the load stops shoving against your vehicle on stops and turns. Buyers shopping this as a 100 gallon Norwesco tank land here for exactly that combination of low profile and slosh control.
Will it work for your job?
This is a polyethylene tank rated at 1.5 specific gravity, meaning it is engineered to carry contents up to 1.5 times the weight of water. Filled with water, a 100 gallon load weighs roughly 834 pounds; the tank structure is rated to a maximum content weight of 1,251 pounds, which gives you headroom for denser water-based fluids without exceeding the shell rating. The flat bottom seats directly on a flat, fully supported surface - a truck bed, trailer deck, or skid - so the entire base carries the load rather than concentrating it on edges or legs. The 42.5 inch dimension is the long axis, so orient it fore-and-aft on a truck bed and confirm bed and door clearance against the 26.75 x 42.5 inch footprint and 27.75 inch height before loading. To match tank volume to your refill cycle and haul weight, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Fittings and connections
Outlet, bulkhead, and lid details are not published in this listing, so there is no fitting or gasket dimension here to cross-reference against your plumbing - do not assume a standard outlet ships. Confirm the outlet size, fitting configuration, and gasket sizing by phone at 866-418-1777 before you order so the tank arrives ready for your hookup.

The mistake to avoid
The most common error with portable water tanks is treating the 1.5 specific-gravity rating as a license to fill completely with any liquid. The rating governs the weight per gallon of the contents, not the chemistry - this is a water-service tank, and your vehicle, trailer, and tie-downs have their own load limits that an 834 pound full water load (or heavier with a denser fluid) can exceed. The second mistake is hauling a partially filled tank without respecting the slosh dynamics: even with the slosh guard cutting wave action, a half-full tank shifts weight, so secure it to a fully supported flat deck and drive accordingly. For portable utility tanks used in farm fleet hauling, the 49 CFR 173.5 agricultural exemption guide covers the DOT classification questions that come up with on-road transport.
