The Bushman 100 Gallon Vertical Emergency Water Storage Tank is a compact blue polyethylene reservoir built to hold a 100-gallon water reserve in a footprint that fits a garage corner, pump house, or shop bay with a properly rated floor. At 42 inches tall on a 30-by-30-inch base, it keeps a known volume of emergency water on hand for households, small systems, and remote sites where having a fixed reserve matters more than floor space.
Will this tank work for your reserve?
This is a vertical water storage tank rated for a specific gravity of 1.0, so it is sized for fresh water rather than heavier fluids. Filled to capacity, the 100 gallons inside weigh about 834 pounds, which is also the maximum rated contents weight. That full load sits on a 30.0 x 30.0-inch footprint, so plan the slab or platform accordingly: the supporting surface needs to be level, solid, and able to carry the full filled weight without flexing. The same dimensions make for a tall, relatively narrow profile, so an empty tank is light and easy to tip or move; site it where you want it and, if it lives outdoors, secure it before filling. If you are weighing this against a larger reserve, the Tank Sizing Calculator and the Tank Sizing Guide walk you through matching stored gallons to days of supply.
How sizing your reserve works
A 100-gallon vertical tank is a common starting point for emergency water storage and short-duration reserve needs. For small systems and rural households mapping out how much water to keep against an outage, our guide on emergency reserve water storage sizing covers the Ten States Standards and AWWA D100 practice behind those numbers. If your reserve doubles as a fire-water source, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. Bushman also builds rainwater harvesting systems, so if you plan to refill this water storage tank from a roof catchment, our walkthrough on first-flush diverter sizing is worth a read.
Two things to get right before you buy
First, this tank carries a 1.0 specific gravity rating, which means it is engineered for fresh water. Do not press it into service for heavier liquids or chemical storage that exceed that rating, since the wall thickness is matched to water density, not to denser contents. Keep this one on water duty; if you need to store a denser fluid, call 866-418-1777 and we will point you to a higher specific-gravity-rated tank (the 1.5 or 1.9 class) built for that load. Second, fitting sizes and locations are not specified in this listing, so confirm your outlet, overflow, and lid plumbing against the technical drawing on this page, or call 866-418-1777, before you commit to a connection plan.
This Bushman tank ships LTL freight from the Fairfield, Texas plant, with freight quoted live to your ZIP code, so transit and cost will vary with distance from that single Texas origin.
