The Norwesco 500 Gallon HDPE Vertical Liquid Storage Tank is a blue, high-density linear polyethylene tank built for upright water and liquid storage where you need real volume in a compact footprint. It measures 48 inches in diameter and stands 73 inches tall, so it tucks into a corner of a pump house, barn, or equipment yard and fits through standard gates without sprawling across the slab. The number that sets this Norwesco apart for water buyers is its 1.9 specific gravity rating: the wall is rated to carry liquids up to 1.9 times the weight of fresh water, which means it is rated well beyond plain water storage and gives you real density headroom if you ever move heavier fresh liquids into it later.
Will it work for your application?
Full of water, this 500 gallon vertical storage tank carries about 4,170 pounds of contents, while the wall is rated to hold up to 7,923 pounds at its 1.9 specific gravity ceiling. Use both numbers to plan your install: a full tank needs a level, continuously supported concrete or compacted base under the entire 48 x 48 inch footprint, never a ring or partial support. Sequence the job around the weight, too. Empty HDPE is light enough to set by hand or forklift, but once it holds water it cannot be moved, so site it, level it, and plumb it before you fill. If you are weighing this against a taller or shorter 500 gallon vertical, run your numbers through the Tank Sizing Calculator and read the Tank Sizing Guide to match drawdown and refill timing to your usage. For fitting locations, outlet positions, and base geometry, see the technical drawing on this page.
The mistake to avoid
The most common error with a vertical HDPE storage tank this tall is treating the headspace like the liquid side. Most premature failures originate at the vapor-saturated zone near the top of the wall, not where the liquid sits, because routine inspection focuses on the wetted surface and misses it. Our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through the ASTM D1998 sizing logic and where to actually look when you inspect. If you are speccing this tank for rural fire-water reservoir duty, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites.
Compare the 500 gallon vertical options
This 48 inch diameter by 73 inch tall blue tank is one of a few 500 gallon vertical formats. If you want to weigh it against the natural white variants, see the buyer's guides for the 48 x 68 natural white build and the 48 x 73 natural white build.
One freight advantage on this tank: we ship it LTL from the nearest of four Norwesco plants covering the western half of the country, Fairfield, TX; Hanford, CA; Tooele, UT; or Washougal, WA, so your rate is built off the closest origin.
