The Bushman 4050 Gallon Vertical Water Storage Tank in dark brown is built for serious bulk water storage on rural, fire-protection, and reuse sites where you need real volume on a single footprint. It stands 129 inches tall on a 101 x 101 inch base and is molded from polyethylene with a 1.0 specific gravity rating, which covers fresh water and other contents at or below the weight of water. Filled to capacity, this vertical storage tank holds 33,777 pounds of water, so the pad and siting decisions matter as much as the tank itself.
Will it work for your site?
At 4,050 gallons on a 101 x 101 inch footprint, this is a large-volume vertical water tank that consolidates storage you would otherwise split across several smaller tanks. The 1.0 specific gravity rating is matched to water and similar-weight liquids; if you are storing anything heavier than water, that rating is your ceiling and you should confirm before filling. The tank ships with a vented manway up top and a 2-inch bulkhead outlet per the technical drawing on this page, so you have a defined outlet and an atmospheric vent. Size your discharge line and any valve to that 2-inch bulkhead. The vented manway has to stay clear on fill as well as draw-down, so the tank never sees positive pressure going in or a vacuum coming out. Inlet and overflow are not pre-defined on this tank's drawing, so plan to add a top inlet and overflow and confirm the gasket and fitting kit for the 2-inch bulkhead before install. Review the manway and fitting callouts on the technical drawing before you plumb anything, since those positions drive your inlet, outlet, and overflow layout.
Sizing the pad, the fill, and the placement
Because a full tank weighs 33,777 pounds, the foundation under it is not an afterthought. A flat, fully supported, level pad sized to the full 101 x 101 inch footprint is the baseline for any above-ground polyethylene tank this size. Our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab carries the load without point-stressing the tank floor. At 129 inches tall — nearly 11 feet — confirm overhead clearance and a crane or forklift plan before the truck arrives, since this tank sets empty and fills in place. To confirm 4,050 gallons is the right capacity for your draw and refill, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first. If this is going into a fire-water reservoir or harvested-rainwater role, the fire-water reservoir design guide and the Bushman rainwater harvesting guide cover sizing discipline and first-flush diverter setup. For grey-water, condensate, or other reuse trains, see the industrial water reuse tank topology guide.
The mistake to avoid
The most common error on a tank this size is treating the 1.0 specific gravity rating as a suggestion. It is the structural limit: this Bushman vertical is rated for contents at the weight of water, and putting a denser liquid in it overloads the wall. Keep it on water-weight service, confirm the vented manway stays vented so the tank breathes during both fill and draw-down, and size the pad to the full footprint and full 33,777-pound loaded weight.
