The Norwesco 13000 Gallon Vertical Liquid Storage Tank is a 13,000-gallon HDPE vessel built for bulk water and liquid storage at agricultural, municipal, fire-protection, and industrial sites that need a single large reservoir rather than a bank of smaller tanks. It stands 198 inches tall on a 144-inch by 144-inch footprint, molded in blue High Density Linear Polyethylene with a 1.9 specific gravity rating. This is the kind of Norwesco vertical storage tank operators reach for when one tank has to hold a meaningful volume of water.
Will it work for your site?
This tank carries a 1.9 specific gravity rating, which means the polyethylene wall is built to hold liquids heavier than water without exceeding its design margin. Filled with water alone (a 1.0 specific gravity liquid), the contents weigh roughly 108,420 pounds; the tank is rated to hold contents weighing up to 205,998 pounds at its full 1.9 specific gravity rating. Because that wall is rated to 1.9 SG, you have nearly double the rated headroom over plain water, so the same tank handles denser liquids up to 1.9 SG without stepping up to a heavier vessel. At 198 inches (16.5 ft) tall on a 12 ft x 12 ft footprint, confirm overhead clearance for fill access and any roof or structure overhead, and confirm the footprint plus working clearance fits the pad site before freight is scheduled. The Tank Sizing Calculator and Tank Sizing Guide help confirm 13,000 gallons is the right volume before you commit to a tank this size.
The mistake to avoid
At this scale, the foundation is where projects go wrong. Size the pad and any anchorage to the full rated load of 205,998 lb (1.9 SG), not just the 108,420 lb water weight — at this footprint that is roughly 97,500 lb of additional dead load your foundation must carry if you ever run a denser liquid. The pad has to stay flat and level under that weight; any settling or edge gap puts uneven stress into the tank wall. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. There is also a less obvious failure point: HDPE tank walls often begin to fail at the vapor-saturated headspace above the liquid line, not at the bottom where you would expect, which is why this breakdown of headspace wall thickness and ASTM D1998 sizing logic is worth reading before you put this tank into long-term service. For fire-water reservoir duty in rural or remote locations, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for this class of tank.
Fittings and going deeper on this size
Fitting sizes and locations are not listed in our spec data for this SKU — confirm the exact outlet, fill, and vent configuration against the technical drawing on this page before ordering gaskets or bulkhead fittings. If you are still weighing whether this is the tank for the job, the complete 13,000-gallon vertical liquid storage tank buyer's guide covers the trade-offs of a single large vertical against alternative configurations, along with what to expect from a tank of this height and capacity.
