The Norwesco 150 Gallon Vertical Liquid Storage Tank (part #41859) is a natural white polyethylene vertical tank that stands 56 inches tall on a 30-inch diameter footprint and is rated for liquids up to a 1.5 specific gravity. The translucent natural white wall lets you read the fluid level at a glance, and the upright profile keeps the footprint compact at just 30 inches across, so it fits the tight pad space, equipment sheds, and back-of-shop corners where a wider vertical storage tank would not.
Will this Norwesco vertical tank work for your job?
This is a 150-gallon working-capacity tank in a standard Norwesco vertical storage tank build. Filled with water it carries roughly 1,251 pounds. Because the wall is rated to a 1.5 specific gravity, it is engineered to hold contents up to about 1,876 pounds at full rating - that is the headroom that lets it store liquids denser than water within the limit. The buying gate here is simple: if your fluid is heavier than water, your loaded weight climbs toward 1,876 pounds, so check your pad, stand, and forklift ratings against that 1,876-pound ceiling, not the 1,251-pound water number. If you are weighing this against a larger or smaller size, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first. Comparing the two 150-gallon verticals?

Fittings and the technical drawing
Outlet, bulkhead, and gasket sizes are not specified in this listing, so confirm them on the technical drawing on this page before you buy any mating fittings or gaskets. The drawing also carries the exact dimensions and fitting locations you will need to plumb the tank in - read it before drilling or ordering hardware.

The mistake to avoid
The most common error on a tank like this is treating the 1.5 specific gravity rating as a license for any liquid. The 1.5 rating governs wall strength for fluid density - it does not make the tank chemically compatible with every product. This is a water and general liquid storage tank, so match your fluid's specific gravity to the 1.5 rating and confirm the contents are appropriate for polyethylene before filling. The 1.5 rating is also the top of Norwesco's standard range; it covers the large majority of stored liquids, but if your product exceeds 1.5 SG, this is not the right tank - call 866-418-1777 to spec a higher-rated build. The other frequent miss is under-building the base: a full tank runs well over half a ton, so pour or set a flat pad at least 30 inches across to fully support the entire tank diameter.
