The Norwesco 210 Gallon Vertical Liquid Storage Tank (SKU N-47401) is a 67-inch-tall polyethylene tank on a 32-inch-diameter footprint, built for above-ground storage of water and liquids up to a 1.5 specific gravity rating. That SG rating is the spec to read first: at 1.5, the wall is engineered to hold contents up to 50 percent denser than water, so this Norwesco vertical tank covers a wider band of liquids than a water-only 1.0-rated vertical of the same size. Buy the headroom once and you avoid replacing the tank when the service gets heavier.
Will it work for your storage job?
The tank holds 210 gallons in a tall, narrow profile that fits tight pads, corners, and indoor mechanical rooms where a wide-diameter tank will not. Full of water it carries about 1,751 pounds; at its maximum 1.5 SG rating the contents alone reach roughly 2,627 pounds, so plan the pad and anchoring for the heaviest liquid you intend to store, not for water. The 32-inch diameter is the dimension to check against your doorway or curb opening before delivery. Installed fitting size, location, and gasket material are shown on the technical drawing on this page, along with overall height and clearance dimensions, so confirm them against your inlet and outlet plumbing before you order. If you are matching this tank to a flow or volume target, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
Common uses and sizing
At 210 gallons this is a practical size for rural water hauling, jobsite supply, equipment make-up water, and small-volume reservoir duty, and the 1.5 SG rating opens it up to moderately heavy process liquids that a standard water-only vertical cannot safely hold. If you are stacking it into a fire-protection or reuse plan, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection, and the industrial water reuse tank topology guide walks through grey-water, rainwater, and HVAC condensate aggregation. For a full walkthrough of this exact model, see the 210 Gallon Vertical Liquid Storage Tank buyer's guide.
The mistake to avoid
The most common error on a vertical storage tank this size is setting it on an undersized or unlevel base. A tank loaded near its 1.5 SG limit can exceed 2,600 pounds of contents, and that load wants a full-diameter, level, continuously supported pad sized for the heaviest liquid you will store, not for water. The tall, slim geometry adds a second failure mode the base does not cover: an empty or near-empty tank is light relative to its 67-inch profile, so strap or anchor it on exposed outdoor pads to prevent tip-over before it is filled. For outdoor cold-climate installs, plan freeze protection such as heat trace or insulation per the fire-water guide above, since the polyethylene wall does not keep the contents from freezing. Our guide to concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework for getting that base right.
