The Norwesco 150 Gallon Plastic Water Storage Tank is a vertical polyethylene tank measuring 30 inches in diameter and 56 inches tall, built for above-ground water storage where a tall, small-footprint profile matters. Filled with water it carries 1,251 pounds, which is the number that drives your pad, your stand, and how you move it once it is full.
Will it work for your site?
This is a 150-gallon vertical storage tank with a 30-inch round footprint, so it fits tight equipment rooms, well houses, and corners where a wider squat tank will not. The 30-inch diameter and 56-inch height give a tall, narrow profile (nearly 1.9:1 height-to-width), trading floor space for vertical reach. A full 56-inch column yields roughly 2 psi of static head at the base outlet — enough to feed gravity lines, but size any pump accordingly if you need pressure for spray or distribution. The tank is molded from polyethylene and rated to a specific gravity of 1.0, which means it is engineered for water and water-weight contents, not heavier chemical solutions. At a full water weight of 1,251 pounds, the base needs to sit on a flat, fully supported surface — see the technical drawing on this page for the exact dimensional layout before you plumb it. If you are unsure whether 150 gallons covers your draw-down or storage window, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide.
Mounting, pad, and plumbing
A 30-inch round base loaded to 1,251 pounds concentrates real weight on a small area, so support the entire bottom — never let the tank bridge across joists or an uneven slab. Fitting and bulkhead configuration (inlet, outlet, vent, lid size) is not listed for this model, so confirm the exact fitting and gasket layout against the technical drawing on this page, or call 866-418-1777 before you order plumbing parts. For a permanent above-ground install, our guide to concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework so the pad carries the full load without settling. After the tank is set and plumbed, follow the hydrostatic test methodology for new-install acceptance to confirm fittings are tight and the pad holds before you put the tank into service. For rural fire-reserve or remote-site water duty, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
The mistake to avoid
The most common error on a vertical tank this size is treating the 1.0 specific gravity rating as optional. It is not. This tank is built for water and water-density liquids; do not put a heavier solution in it expecting the same service life. Reuse applications — grey water, rainwater, or HVAC condensate aggregation — are fine within that water-density band, and the industrial water-reuse topology guide shows how to band storage by water quality. The second mistake is under-building the base: 1,251 pounds is unforgiving on a weak slab.
