The Norwesco 55 Gallon Portable Flat Bottom Utility Tank in white packs 55 gallons into an 18" x 18" footprint that stands 44" tall - a dense, narrow column built for tight truck beds, trailers, and equipment bays where a wider tank would not fit. Full of water it weighs about 459 lb, and the polyethylene wall is rated to carry contents up to 688 lb, so this Norwesco utility tank gives you real headroom above plain water.
Will it work for your job?
This is a 1.5 specific-gravity-rated tank, meaning the wall is built to hold a liquid up to 1.5 times the weight of water. For straight water that rating is generous and leaves a long service margin; it also means the same tank handles heavier solutions - fertilizer mixes and similar liquids - up to the 688 lb maximum rated contents weight without stepping up to a thicker-wall model. If you are specifying for water today but your service might change later, that built-in headroom is the reason to buy this tank now. The flat bottom lets it sit directly on a deck or pad with no stand. Use the Tank Sizing Calculator to confirm 55 gallons covers your draw, and the Tank Sizing Guide if you are weighing this against a larger Norwesco utility tank.
Fittings and what you need to add
The tank is threaded for a single 5" cap at the top (see the technical drawing on this page for the exact layout). No outlet, bulkhead, or gasket ships installed - this tank arrives with one 5" threaded port and nothing else, so plan on sourcing a 5" cap and any outlet bulkhead and gasket sized to that thread before you fill it. Confirm there is exactly one port and lay out your plumbing around it.
Mounting and weight planning
The 44" height on an 18" base puts the filled center of gravity high, so a full tank's 459 lb rides up where it can shift a load. Strap it with tie-downs rated for that weight and keep it low and forward in the bed; if you intend to haul a heavier-than-water solution, design your platform and straps around the 688 lb maximum instead. For fleet and farm hauling specifics, the guide on Norwesco portable utility tanks and the 49 CFR agricultural exemption covers DOT classification for farm fleet use.
Where it ships from and how freight works
This Norwesco white utility tank ships LTL freight, quoted live to your ZIP - typically from the Sheldon, IA plant, with stock also moving from Iowa and Mississippi, so a southern buyer may draw a closer origin. Because freight on a tank this size depends on delivery distance and location, get a real number before you order with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. Listed price is before freight; LTL is quoted separately to your ZIP. For larger storage or reservoir projects, the guides on concrete pad sizing for above-ground polyethylene tanks and fire-water reservoir tank design for rural sites cover sizing discipline and freeze protection.
