The Bushman 100 Gallon Plastic Vertical Liquid Storage Tank in dark green is a 100-gallon polyethylene water storage tank built for tight-footprint general water service. It stands 42 inches tall on a 30 x 30 inch footprint, so it slots into a corner, a pump house, a trailer bed, or alongside a well system without claiming much floor space. As a vertical storage tank, it stores water upright and gravity-feeds or pump-feeds from the bottom outlet, making it a practical 100 gallon tank for hauling, backup supply, and point-of-use storage.
Will this tank work for your water
This is a polyethylene tank rated to a specific gravity of 1.0, which is exactly water's density. That rating means it is sized for water and water-weight liquids, not heavier chemical solutions. Filled to capacity, 100 gallons of water weighs about 834 pounds, and that 834-pound full-water load is the maximum rated contents weight for this tank. Plan your stand, pad, or platform for that number, not the empty weight: a level, fully supported base under the entire 30 x 30 inch footprint is what keeps a vertical tank stable and the fittings from taking stress. If you are weighing this 100-gallon size against a taller or wider model, the Tank Sizing Calculator and the Tank Sizing Guide walk you through matching capacity and footprint to your space and refill cycle.
Fittings, fill port, and level reading
The tank comes with a 2-inch FNPT spin-weld polyethylene fitting for your outlet plumbing and a 10-inch OD / 8-inch ID twist-lid assembly on top. That twist lid is your fill, inspection, and access port, and it is also where you would drop in a fill float or float switch on a backup-supply or auto-fill rig. The 2-inch outlet fitting is molded polyethylene, so it matches the tank wall rather than relying on a bolted gasket flange; the gasket and thread-seal step belongs at your downstream connection, where a 2-inch FNPT bulkhead, valve, or male-NPT cam-lock or hose adapter threads in with PTFE tape or thread sealant. Confirm your hose, valve, or bulkhead threads to a 2-inch FNPT connection before you order adapters. One thing to note: this tank has no molded gallon graduations, so for haul or batch metering, plan a sight tube or external gauge off the 2-inch outlet. For exact fitting placement and dimensions, see the technical drawing on this page.
The mistake to avoid
The one to watch on this tank is the specific gravity rating. At SG 1.0 it is built for water; it is not rated to safely hold liquids heavier than water, such as concentrated fertilizers, brines, or many chemical solutions, which can exceed SG 1.0 and overstress the wall over time. If your liquid is one of those heavier products, you need a higher-SG-rated tank instead, not this one. Call us at 866-418-1777 and we will point you to a tank built for that weight. Used as a water storage tank within its rating, this Bushman vertical tank is a durable, single-size workhorse for hauling, backup supply, and point-of-use storage.
