The Norwesco 200 Gallon Vertical Water Storage Tank in black is a polyethylene vertical water tank built for steady on-site water storage where you need real volume in a compact footprint. Measuring 30 in. diameter x 72 in. height, it holds 200 gallons of water within a footprint just 30 inches across. That tall-and-narrow geometry is what makes this size useful: it fits along a wall, in a pump-house corner, or on a trailer pad without eating up the floor space a squat 200 gallon tank of the same capacity would demand.
Will it work for your water storage job?
This is a dedicated vertical water storage tank rated to a specific gravity of 1.0, which means it is engineered for water and water-weight contents. Filled to capacity, 200 gallons of water weighs about 1,668 pounds, and that full load sits on the 30-inch-diameter footprint. Plan your pad accordingly: a level, fully supported concrete or compacted base under the entire bottom is what keeps a tall vertical tank stable and the wall stress even. The black polyethylene wall blocks light, which suppresses the algae growth that plagues translucent tanks in outdoor service, so this is a sound pick for rural water supply, fire-water reserve, rainwater holding, and general bulk water storage.
Sizing it right
If you are weighing this 30 x 72 tank against the shorter, wider 35 x 59 version of the 200 gallon black tank, the choice comes down to your space and your fill height. Our Tank Sizing Calculator and Tank Sizing Guide walk you through matching capacity, footprint, and head height to your draw rate. For two detailed walk-throughs of this exact capacity, see the 200 Gallon (30 x 72) Buyer's Guide and the 200 Gallon (35 x 59) Buyer's Guide. For larger reserve planning, our coverage of fire-water reservoir tank design for rural sites and industrial water reuse tank topology covers grey-water, rainwater, and condensate aggregation.
The mistake to avoid
This tank carries a 1.0 specific gravity rating, which is the giveaway that it is built for water, not for heavier liquids. Do not press a water-rated tank into chemical or high-density service. If your contents are heavier than water, you need a tank rated to a higher specific gravity, and a call to 866-418-1777 will get you a higher-SG recommendation for that load. This is a closed water-storage tank, so before you plumb your inlet and discharge, check the technical drawing on this page for exact port and outlet locations and confirm that placement suits your application.
