Norwesco 5000 Gallon Vertical Storage Tank 1.5 S.G. in Black no Fitting

The Norwesco N-40346 is a 5000-gallon vertical storage tank rated to 1.5 specific gravity, molded in black polyethylene and shipped with no fitting installed so you spec the outlet and bulkhead placement yourself. It stands 152 inches tall on a 102-inch diameter footprint and weighs 986 pounds empty. The 1.5 SG rating is the number to read first: it means the wall is validated to hold liquids up to 1.5 times the density of water, so on straight water (1.0 SG) you are well inside its structural rating. That makes it a heavy-duty choice for bulk water and general liquid storage.

Will it work for your site?

Full of water this tank holds roughly 41,700 pounds of contents. At the full 1.5 SG rating the arithmetic (5,000 gal x 1.5 SG x 8.34 lb/gal) works out to about 62,550 pounds of rated contents, so plan your pad for real load - a 102-inch diameter circle carrying 20-plus tons demands a level, engineered base. Our Tank Sizing Calculator and Tank Sizing Guide help you match a 5000 gallon tank to your draw-down and refill cycles, and the concrete pad sizing guide walks the ACI framework for a foundation this size. The tank has a 16-inch lid for access and inspection, an FDA-approved resin, and a maximum service temperature of 120 F (48 C). Because it ships with no fitting, confirm your outlet size and gasket material at order time - sized for the head pressure of a 152-inch liquid column - and order the bulkhead hardware alongside the tank so nothing holds up your install.

Common bulk-water applications

At 5000 gallons this Norwesco vertical is a workhorse for rural fire-water reserves, industrial process water, and water-reuse storage. If you are sizing a private fire-protection reservoir, the NFPA 22 fire-water reservoir design guide covers sizing discipline and freeze protection for cold-climate sites. For grey-water, rainwater, and HVAC condensate aggregation, the industrial water-reuse topology guide shows where a tank this size fits in a quality-banded storage train. Once it is set and plumbed, follow the hydrostatic test methodology to confirm the install before you commit it to service.

One thing not to overlook

The most common mistake on a tank this large is treating the 1.5 SG rating as an invitation to store anything. This is a water and general liquid-storage tank - the SG rating tells you the wall handles denser-than-water contents mechanically, but it says nothing about chemical resistance. If you have a specific chemical in mind, confirm resin compatibility before you fill it. And because it ships without fittings, size and locate your outlet for the full head pressure of that 152-inch column; an undersized or poorly placed bulkhead is the failure point buyers regret. See the technical drawing on this page for exact port and dimensional detail.
