The Norwesco 140 Gallon HD Vertical Storage Tank is a natural white polyethylene vertical tank built for reliable above-ground water storage in a compact footprint. Standing 73 inches tall on a 25 x 25 inch base, this vertical storage tank holds 140 gallons in a straight-wall profile that stores real volume without spreading across your pad. The "HD" designation reflects a heavy-duty build rated to a 1.9 specific gravity, so the tank wall is engineered for contents heavier than plain water.
Will it work for your site?
Filled with water, this Norwesco tank carries roughly 1,168 pounds of contents, and it is rated to hold up to about 2,218 pounds at its 1.9 specific gravity limit. Plan your pad and support around that 2,218-pound maximum load: a full vertical tank concentrates weight on a 25 x 25 inch footprint, so it needs a level, continuously supported base beneath the entire bottom. If you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to your draw and refill cycle.
Where the 1.9 rating matters
The 1.9 specific gravity rating gives you extra wall-strength headroom for rainwater, fire-reserve, and general bulk water storage. The mistake to avoid runs in the opposite direction from most tanks: buyers often under-spec wall strength for dense contents, and here you already have margin. Use that margin for demanding, long-service water duty rather than pushing the tank toward chemistry it was not quoted for. One note before you plumb it: fitting and gasket configuration is not specified in our data for this SKU, so call 866-418-1777 to confirm outlet size, bulkhead fitting, and gasket before ordering any plumbing parts. You can also review the technical drawing on this page for dimensional detail.
Common uses
This size suits rural and remote water setups well, including fire-water reservoir builds where a compact vertical tank anchors the private fire-protection stack. See Fire-Water Reservoir Tank Design for Rural and Remote Sites for NFPA 22 sizing discipline and cold-climate freeze protection. Before you set it, review Concrete Pad Sizing for Above-Ground Polyethylene Tanks so your foundation carries the load correctly. If you are aggregating grey-water, rainwater, or HVAC condensate, the Industrial Water Reuse Tank Topology guide covers quality-banded storage trains, and rainwater harvesters should read the first-flush diverter sizing guide.
