The Norwesco 2000 Gallon Vertical Liquid Storage Tank is a white polyethylene vertical tank built for bulk water and liquid storage where you need real capacity in a tight footprint. It stands 84 inches tall on a 90 by 90 inch base, holds a true 2000 gallons, and carries a 1.5 specific-gravity rating, so it has structural headroom for liquids heavier than water without pushing the wall past its design limit. If you have been searching for a Norwesco vertical storage tank in the 2000-gallon class, this is the workhorse size that anchors most rural water, irrigation, and stored-supply systems.
Will it work for your site?
The two numbers that drive your install are the loaded weights. Full of water this tank weighs about 16,680 pounds, and at its maximum 1.5 SG rating it can carry up to 25,020 pounds of contents - so your pad must be rated for roughly 25,020 pounds loaded, square to the 90 by 90 inch footprint, with clearance on every side for plumbing and inspection access. A tank this size needs a level, continuously supported base: a reinforced concrete slab or compacted, ringed pad that holds the full loaded weight without point-loading the bottom. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you pour, and size the slab against the loaded weight, not the empty tank weight.
The 1.5 SG rating: what it does and doesn't mean
The 1.5 specific-gravity rating is a structural number - the wall is built to support a liquid up to 1.5 times the density of water. That makes this tank the correct choice when your liquid is heavier than plain water, where a standard 1.0 or 1.35 SG tank would be under-rated. It is not a chemical clearance, and it is not a potable or food-grade statement. For ordinary water - well supply, hauled water, irrigation reserve, livestock supply - the 1.5 rating is generous overhead. If you are storing anything denser than water, confirm your liquid's specific gravity stays at or under 1.5 and verify the wall is rated for the full loaded weight you calculated above before you commit.
Fittings, venting, and freeze protection
Outlet, bulkhead, and lid provisions vary by build, so call 866-418-1777 to confirm the exact fitting and gasket schedule for this SKU before you order plumbing - don't assume a configuration. Atmospheric vent and freeze-protection hardware are sized and supplied separately; for a closed vertical of this size, work through our API 2000 atmospheric vent sizing guide so inbreathing and outbreathing are handled correctly, and review the technical drawing on this page for dimensional detail.
Comparing your options
If you are weighing brands at this capacity, our Snyder vs Norwesco vs Chem-Tainer 2000 gallon vertical comparison breaks down the differences, and the 2000 gallon vertical storage tank buyer's guide walks through specs and applications (note that guide covers a different-dimension variant; this SKU is the 84 by 90 by 90 inch tank). If this tank is feeding a private fire-protection reserve, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
