The Norwesco 120 Gallon Vertical Water Storage Tank is a compact green polyethylene vertical tank built for residential and rural water storage where space is tight and a small, stable footprint matters. It holds 120 gallons in a 38-inch diameter by 31-inch tall body, with a 38.0 x 38.0-inch footprint that drops onto a small pad or platform without consuming the area a larger vertical tank demands. This is the green California-only color variant from Norwesco, well suited to water storage, hauling reserve, irrigation buffering, and use as a building block in a vertical storage train.
Will this vertical water storage tank work for your job?
The polyethylene shell carries a 1.0 specific gravity rating, which means it is built for water only. Do not use it for fertilizer, brine, or any liquid heavier than water (specific gravity above 1.0). Filled to capacity, the tank holds 120 gallons at a full water weight of 1,001 pounds, which is also the maximum rated contents weight, so plan your pad, stand, or platform around roughly 1,000 pounds of static load plus the empty tank. The technical drawing on this page shows the fitting layout, including a sump with a 4-segment configuration and the revised lid thread. Because the inlet, outlet, and vent thread sizes are shown only on that drawing, confirm them there before buying bulkhead fittings or gaskets so your inlet, outlet, and vent runs line up. For multi-tank or odd-volume installs, the Tank Sizing Calculator and Tank Sizing Guide help you confirm 120 gallons is the right increment before committing.
How this Norwesco tank ships to you
This Norwesco vertical tank ships LTL freight from the nearest stocking plant, which for this SKU is Hanford, California. This green variant is produced and stocked only in California, so buyers outside the West should expect longer LTL transit and quote freight to ZIP accordingly. Freight is quoted live to your ZIP code rather than baked into the list price, so use the Freight Cost Estimator to see a real number for your delivery address, or call 866-418-1777 for help. Because this is a vertical storage tank under a thousand pounds full and modest in diameter, it crates and moves cleanly on a single pallet, but always confirm the gated quote for your location before you budget the install.
The mistake to avoid
The most common error on a tank this size is under-building the base. At 1,001 pounds full on a 38 x 38-inch footprint, the load concentrates on a small area, and an unlevel or undersized pad will let the tank rock, stress the lid thread, and strain the sump fitting at the bottom. Set it on a flat, fully supported, level surface sized to carry the full water weight. If you are planning a permanent above-ground install, walk through concrete pad sizing for above-ground polyethylene tanks first, and before you put the tank into service, run a proper fill test using the hydrostatic test methodology for new-install acceptance to catch any fitting leak or pad settlement before it becomes a problem.
