The Norwesco 220 Gallon Dark Green Vertical Water Storage Tank is a 220-gallon polyethylene vertical tank that stands 44 inches tall on a true 42 by 42 inch square base, a near-cubic profile that fits low-clearance sheds and pump houses where a tall, slim vertical will not clear the roof. The dark green color cuts light penetration to slow algae growth in outdoor service, and the tank carries a 1.0 specific gravity rating, meaning it is engineered for the weight of water and water-density liquids.
Will this tank work for your water storage job?
At full fill this tank carries roughly 1,835 pounds of contents, which is also its maximum rated contents weight, so it is built to hold a full load of water continuously rather than a denser liquid. That load number sets your pad requirement: our guide on concrete pad sizing for above-ground polyethylene tanks walks through supporting a full vertical tank on a 42-inch-square footprint. If you are deciding between this 220-gallon size and a larger or smaller vertical storage tank, run your draw rate and refill cycle through the Tank Sizing Calculator and the Tank Sizing Guide.
Fittings: confirm on the drawing before you order plumbing
This listing does not enumerate outlet size, bulkhead fitting, or gasket specification. The technical drawing on this page carries the current lid-thread and fitting detail, so confirm the bulkhead, outlet, and gasket arrangement against the drawing before you buy plumbing. If anything is unclear, call us at 866-418-1777 and we will read the spec with you rather than have you guess.
How it ships and what freight looks like
This vertical storage tank moves by LTL freight, fulfilled from the nearest Norwesco plant to your delivery ZIP. With regional stocking points spanning Fairfield, TX; Griffin, GA; Owego, NY; and Shawnee, OK, most of the lower 48 sits within one freight zone of a plant, which keeps your cost and transit time down. Freight is quoted live to your ZIP, so get an exact number before you commit using the Freight Cost Estimator or by calling 866-418-1777.
The mistake to avoid
The most common error with a water storage tank like this is loading it with something heavier than water. The 1.0 specific gravity rating means the wall is engineered for water-density contents only. For chemical or brine service, step up to a 1.5+ SG-rated vertical built for the higher load, not this tank. Once the tank is set on its pad, our guide on hydrostatic test methodology for new-install acceptance covers filling discipline and leak checks before service. For rural fire-reserve or reuse applications, see our guides on fire-water reservoir design and industrial water reuse tank topology.
