Norwesco 25 Gallon Rectangular Flat Bottom Utility Tank with Fitting in White

The Norwesco 25 Gallon Rectangular Flat Bottom Utility Tank (SKU N-45879) is a compact, White polyethylene tank built for portable water handling where a low, stable profile matters more than vertical height. At 34 inches long, 14 inches wide, and just 12 inches tall, it sits low on a truck bed, trailer, or utility skid, and its flat bottom keeps it planted on a pad without a stand. It holds 25 gallons and weighs only 15 pounds empty, so one person can lift and position it before filling. It shows up in searches as a "25 gallon" Norwesco "rectangular flat bottom utility" tank, and this is that tank.

Will it work for your job?

This is a loaf-style utility tank sized for small-batch water transport and dispensing. Filled with water it carries about 208 pounds of liquid, so with the 15-pound empty tank you are looking at roughly 223 pounds of static load — and it is rated to a maximum contents weight of about 313 pounds, which corresponds to its 1.5 specific gravity rating. Plan your deck, shelf bracket, or pad for that range. That SG headroom is the number to check first: as long as your liquid weighs no more than 1.5 times water and stays within the tank's compatibility, the wall structure is within its design limit. The 14 x 34 inch footprint tells you the space to reserve. A 0.75-inch outlet handles gravity draw-down or a small transfer pump — treat it as the flow limiter, since it is garden-hose scale, not a high-flow dump — and the 5-inch lid gives you a fill and inspection opening up top. The resin carries an FDA-approved rating for potable contact. Not sure this capacity fits your duty cycle? Run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide.

Watch the service temperature

Maximum service temperature is 120 F / 48 C. That is a real ceiling for a portable tank that may sit in the sun or hold a dark, heat-absorbing liquid — hot-fill or sustained high-temperature service at that limit will de-rate the polyethylene, so keep your contents below it.

The mistake to avoid

The 1.5 specific gravity rating is a weight ceiling, not an invitation to fill this with any liquid. Confirm your product's specific gravity before you load it — a solution heavier than 1.5 SG will overstress the walls even though the gallon mark says there is room. For farm-fleet and agricultural transport, the classification rules matter too; our guide on Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption walks through when a farm-use tank is and isn't exempt. If you are setting it on a permanent base rather than a vehicle, review concrete pad sizing for above-ground polyethylene tanks. See the technical drawing on this page for the full dimensional layout before you build a mount.
