The Norwesco 40 Gallon HD Vertical Storage Tank is a compact, heavy-duty polyethylene vertical tank built for water and general storage where floor space is tight. It stands 43 inches tall on an 18 x 18 inch footprint and holds 40 gallons in a natural white polyethylene shell. This is the HD version, molded from polyethylene and carrying a 1.9 specific gravity rating, so it handles fluids denser than water within its rated capacity.
Will it work for your setup?
The small 18 x 18 inch footprint makes this Norwesco vertical storage tank a good fit for utility closets, trailers, skid systems, and equipment rooms where a taller, narrower profile beats a wide one. Filled with water it holds about 334 pounds of contents (40 gallons of water is roughly 334 pounds), and at the 1.9 specific gravity rating the shell is built to carry up to about 634 pounds of contents. That 634-pound figure is what makes this the HD spec: a standard 1.5 SG tank would not give you the same headroom for denser fluids. To match capacity to your actual demand, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Fittings and mounting
Outlet and fitting sizes are not published in this listing, so confirm them from the technical drawing on this page before you plumb the tank in. Because a vertical tank concentrates its weight over a small base, set it on a flat, fully supporting surface, a level, continuous pad or platform rated for the full contents weight plus the tank's own dry weight (add that from the technical drawing) and a safety margin. Never support the tank on a partial ledge or let it overhang its base. If you are pouring a concrete base, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework so the pad carries the tank evenly.
The mistake to avoid
The common error with a small-footprint vertical tank is loading it with a fluid heavier than the shell is rated to carry. Stay within the 634-pound maximum contents weight; if your fluid's specific gravity would push the load past that, size up rather than overfill. For water and comparable-density storage this 40 gallon tank has ample margin, but confirm your fluid's specific gravity first.
