The Norwesco N-41399 is a 2,100 gallon vertical liquid storage tank molded from polyethylene, standing 69 inches tall on a 102-inch diameter footprint in natural white. This is a Norwesco vertical storage tank built for above-ground bulk liquid storage where you need real volume without going taller than a standard ceiling or door header. Because natural white polyethylene is translucent, you can read the liquid level straight through the tank wall without opening the lid - a genuine day-to-day advantage when you are checking a water or rinse-water supply at a glance.
Will it hold what you're storing?
This tank carries a 1.5 specific gravity rating, which means the wall thickness is engineered to safely hold liquids up to 1.5 times the weight of water. Filled with water (specific gravity 1.0), 2,100 gallons weighs about 17,514 lbs resting on that 102-inch diameter base. At its full 1.5 SG rating the tank is built to support up to 26,271 lbs of contents - that headroom is what lets you store heavier-than-water liquids without overstressing the wall. Plan your pad and foundation for the loaded weight, not the empty tank: a slab sized for the 102-inch diameter and rated for the full contents load is the single most important part of a successful install. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 2,100 gallon size fits your draw-down and refill needs before you order.
Reading the technical drawing before you plumb
See the technical drawing on this page for fitting locations, lid size, and outlet placement so you can plan plumbing and overflow before the tank arrives. The outlet and bulkhead fitting size are not enumerated here, so confirm the exact fitting dimensions, and verify that the gasket and seal material is right for the liquid you are storing, against that drawing rather than assuming. If you are weighing this 102" x 69" size against more volume, the larger Norwesco verticals share this same 102-inch base diameter - so stepping up to the 2,500 gallon (102" x 79") or 3,000 gallon (102" x 93") gets you more gallons on the very same pad. A bigger tank goes up in height, not width, so if you are on the fence about draw-down you can add capacity without re-pouring a wider foundation. The complete buyer's guide for this exact tank walks through the spec sheet in detail.
Avoid the most common mistake on this size
The mistake that catches buyers on a 2,100 gallon vertical is treating the empty footprint as the planning number. A tank weighing more than 17,500 lbs full needs a level, fully supporting base - never set a large vertical on uneven ground, blocking, or a partial pad, because the polyethylene is designed to be uniformly supported across the entire bottom. Get the foundation right and this tank will run for years.
