The Norwesco 220 Gallon Plastic Water Storage Tank (SKU N-43870) is a vertical polyethylene tank that stands 44 inches tall on a 42-inch diameter footprint, holding 220 gallons in a compact circle that fits through most gates and into tight corners along a wall or inside a pump house. If you are sizing a tank for residential water storage, livestock supply, rainwater capture, or a small fire-water reserve, this is one of the most placement-friendly capacities Norwesco builds.
Will it work for your job
This vertical storage tank is rated to a specific gravity of 1.0, which is the design point for water and contents no heavier than water. Filled to its full 220 gallons, the tank carries roughly 1,835 pounds, and that 1,835-pound figure is also the maximum rated contents weight. Use it for water only: for fertilizer, brine, or any chemical denser than water (above SG 1.0), you need a tank rated to a higher specific gravity, not this one. The 42-inch diameter base spreads that full load to roughly 190 pounds per square foot, the bearing number to confirm your pad and soil can carry before you pour. Run your daily draw and refill cycle through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 220 gallons is the right size before you commit.
Fittings and setup
The lid thread on this tank was revised per the current technical drawing, so match any aftermarket lid or vented cap to the thread shown on the drawing rather than an older spec. See the technical drawing on this page for the lid layout and confirm the lid thread before ordering a cap and gasket. This tank ships with the threaded lid as its defined fitting; outlet and bulkhead fittings are added per your plumbing plan, with the bulkhead and gasket sized to your pipe, so plan those locations against the drawing before the tank arrives. For a new install, our hydrostatic test methodology guide walks through fill discipline, pad settlement monitoring, and fitting-leak checks for acceptance, and the concrete pad sizing guide covers the ACI framework for the above-ground base that has to carry that 190 lb/ft².
Putting it to use
At 220 gallons this size lands between a small portable reserve and a full bulk vertical tank, which makes it a common pick for rural and remote water storage where space and access are limited. Where this tank feeds a private fire-protection setup, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. If you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse topology guide explains how a vertical storage tank this size fits a quality-banded storage train.
