Norwesco 2500 Gallon Vertical Water Storage Tank in Green Without Fitting

The Norwesco 2500 Gallon Vertical Water Storage Tank (SKU N-42232) is a Hanford, California-built polyethylene tank for bulk water storage, sold here in California Green without a fitting installed so you spec the outlet and bulkhead exactly where your plumbing needs it. It's a squat vertical cylinder — 91" tall on a 95" diameter body, so it sits wider than it is tall — weighs 340 lb empty, and is FDA-approved polyethylene rated to a 1.1 specific gravity with a 120 F / 48 C maximum contents temperature. If you have been searching for a 2500 gallon Norwesco vertical water tank, this is the workhorse cylinder for the job.

Will it work for your site?

This is a self-supporting vertical cylinder that must sit on a level, fully-supporting pad sized to the full 95" diameter — the entire base carries the load, so a smaller slab will not do. Filled with water, plan for roughly 20,850 lb of contents on that footprint. The 1.1 SG rating allows up to about 22,935 lb of rated contents — roughly 10% above water weight — so as long as your liquid is at or below 1.1 specific gravity you are inside spec. The 16" lid gives you top access for filling, level sensors, and inspection. Use our Tank Sizing Calculator and Tank Sizing Guide to confirm 2500 gallons matches your draw and refill cycle before you buy.

The mistake to avoid

Because this tank ships without a fitting, the outlet is yours to place — call 866-418-1777 and we will help you spec a properly gasketed bulkhead sized to your pump, and support the plumbing independently so the tank wall carries no piping weight. Just as important: this tank is rated to a 1.1 specific gravity. Water sits at 1.0, so you have margin for water service, but do not repurpose it for a denser liquid without confirming the SG rating covers it. Set the pad first — a vertical tank on an uneven or undersized base is the most common and most expensive install error. Commission it correctly with a proper fill test, walked through in our hydrostatic test methodology guide, and size the slab per our concrete pad sizing guide.

Fit for the job

At 2500 gallons this size suits rural fire-water reserves, irrigation, and industrial water-reuse trains. For a standing fire reserve, remember that at 340 lb empty a 95"-wide tank is light on a wet pad — wind uplift, buoyancy, and freeze protection all matter when the tank sits full for long periods; our fire-water reservoir design guide walks through NFPA 22 sizing and cold-climate anchoring, and our industrial water reuse topology guide covers grey-water and rainwater trains. Check dimensions and the lid location against the technical drawing on this page before you finalize your pad and plumbing layout.
