The Bushman 4050 Gallon Vertical Water Storage Tank (BM-45552) is a polyethylene bulk-water vessel standing 129" tall on a 101" x 101" footprint, rated for 4,050 gallons of water storage in dark green. Built for vertical water storage where a large, stable reservoir matters, it ships from Bushman's Temecula, California plant and carries a 1.0 specific gravity rating, which means it is engineered for water and other contents at or below the density of water.
Will it work for your site?
This is a vertical tank with a 101-inch diameter base and a 129-inch overall height, so plan your pad and overhead clearance around those numbers before you order. Filled to capacity, the tank and its water weigh 33,777 pounds, and the maximum rated contents weight is the same 33,777 pounds at a 1.0 specific gravity. Worth understanding for the foundation: the tank ships empty and light, then loads to roughly 16.9 tons on fill and returns toward empty as you draw it down, so the slab below sees that full load arrive and recede cyclically. A properly sized, level foundation is not optional - our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for designing the slab under a tank this heavy. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 4,050-gallon capacity and footprint suit your draw and your space.
Fittings and configuration
The tank comes with a vented manway for filling, inspection, and access, plus a 2" bulkhead fitting per the technical drawing on this page. That 2" bulkhead is your outlet - the draw and plumbing connection - so size your supply line, fittings, and gaskets to a 2" port, since besides the manway it is the only listed penetration on the tank. Review the technical drawing for the exact fitting locations and the manway placement before you plumb your inlet and outlet, because fitting positions drive how you route supply and draw lines. One practical caution: confirm the bulkhead gasket is seated and properly torqued before you fill, because the 2" bulkhead, not the tank wall, is the most common leak point on a poly tank. The vented manway matters here too - it lets the tank breathe as the water level rises and falls so you do not pull a vacuum on draw-down or pressurize the head space on fill. At a 2" outlet a fast pump draw is exactly when vacuum-collapse risk is highest, so keep that manway vent clear.
Common applications and the mistake to avoid
At 4,050 gallons this size works well as a vertical storage tank for water storage on farms, rural sites, and remote properties - including the fire-water reservoir and rainwater harvesting duty covered in our guides on fire-water reservoir tank design - which also covers freeze-protection engineering worth reading if this green tank is going outdoors in a cold climate - plus Bushman rainwater harvesting and industrial water reuse topology. The mistake to avoid: this tank carries a 1.0 specific gravity rating, so it is matched to water. Do not put a heavier-than-water liquid in it - a fluid denser than water exceeds the wall design and the 33,777-pound contents rating, and that is a different tank specification entirely. Keep this one on water.
