The Norwesco 2500 Gallon Vertical Water Storage Tank (SKU 42232) is a free-standing polyethylene tank molded in California Green, built for bulk water storage where you need real volume on a stable footprint. It holds 2,500 gallons in a 95-inch diameter body standing 91 inches tall, and it ships without a fitting so you can specify the bulkhead and plumbing your install actually calls for. Empty weight is just 340 lb, so an empty tank is a roll-into-position job — but plan to have it in its final spot before any water goes in, because at full it carries roughly 20,850 lb and cannot be moved.
Will this tank work for your water job?
This is a vertical water tank with an FDA-approved polyethylene wall, rated for potable and drinking-water storage — the concrete reason it beats a generic industrial tank for a water job. It has a 16-inch lid for access and inspection and a 1.1 specific gravity rating. Rated maximum contents temperature is 120 F / 48 C, which makes it right for ambient and cold-supply water and cold-climate reserve, but not for heated or hot-water service or any process fluid above that ceiling. The 1.1 SG rating is worth understanding: it means this exact tank is rated for water plus slightly denser liquids up to a specific gravity of 1.1 — think light brines or some ag solutions — without derating. That is 22,935 lb of maximum rated contents versus 20,850 lb for plain water, so if your fluid runs heavier than water this is the tank that carries it where a 1.0-SG-only unit would not. See the technical drawing on this page for the lid and body layout before you finalize plumbing.
Getting the size and the pad right
If you are still choosing between capacities, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit. A 2,500-gallon vertical tank is a common pick for rural fire reserve, water reuse trains, and general bulk storage — our fire-water reservoir design guide and industrial water reuse topology walk through how these tanks fit each stack.
The mistake to avoid
The biggest error on a tank this size is the pad, not the tank. A full 2,500-gallon vertical concentrates over 20,000 lb on a 95-inch circle, so an underbuilt or unlevel base leads to settlement and fitting stress. Pour and cure a properly sized, level slab first — our concrete pad sizing guide covers the ACI framework — then run a hydrostatic acceptance fill to catch leaks and settlement before you rely on it. Because this tank ships bare — the only molded access point is the 16-inch lid — confirm your bulkhead and gasket selection before you order; call 866-418-1777 and we will spec it so the plumbing is right the first time.
