Norwesco 750 Gallon Vertical HD Liquid Storage Tank in White without Fitting

The Norwesco 750 Gallon Vertical HD Liquid Storage Tank (N-40609) is a straight-wall vertical tank molded in high-density polyethylene for indoor or outdoor bulk liquid storage. It stands 103" tall on a 48" diameter footprint, weighs 155 lb empty, and ships in white without a fitting installed, so you spec the bulkhead and gaskets to match your service. This is a workhorse 750 gallon vertical tank for water, and the specifications below tell you exactly what it will and won't hold.

Will it work for your liquid?

This tank carries a 1.5 specific gravity rating, meaning the wall is built to hold contents up to 1.5 times the weight of water. Full of water, expect roughly 6,255 lb of contents; at the full 1.5 SG rating the tank is engineered to carry up to 9,382 lb. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm your fill height and contents weight before you order. The tank ships with a 16" lid and is set up for a 2" outlet, is rated to a maximum contents temperature of 120 F / 48 C, and is FDA approved. Because it comes without a fitting, you have a clean wall to locate that 2" outlet and any additional bulkheads where your plumbing runs best.

Sizing and placement

At 103" tall the tank needs adequate overhead clearance for the 16" lid and any fill plumbing. The placement number that matters is the loaded figure: at the full 1.5-SG rating the pad carries about 9,382 lb of contents plus the 155 lb tank, roughly 9,537 lb bearing on a 48" (about 12.6 sq ft) circle. Plan a level, engineered pad or slab rated for that load. For rural water reserve, fire-reservoir, or general liquid-storage duty, see our 750 gallon vertical (48" x 103") buyer's guide and the companion 46" x 107" guide for the alternate mold. If this is a private fire-protection reserve, our NFPA 22 fire-water reservoir guide walks through sizing discipline and cold-climate freeze protection. Outgrowing 750? The 2000 gallon vertical guide covers the next step up.

The mistake to avoid

Respect the 1.5 SG rating: it defines the heaviest liquid this wall is built for. If your product is heavier than 1.5 specific gravity, this is the wrong tank, and you should confirm your specific gravity before you buy rather than after. Because N-40609 ships without a fitting, the bulkhead, gasket, and outlet material are also yours to spec at the 2" outlet — choose them for your liquid, not just the tank. Call us before ordering if you want that hardware matched to your contents.
