The Bushman 100 Gallon Vertical Water Storage Tank is a compact, freestanding polyethylene tank built for reliable general water storage and buffering duty where floor space is tight. At 23 inches in diameter and 63 inches tall, it holds a full 100 gallons on a footprint just 23 x 23 inches, so it drops into a pump-house corner, a utility closet, a well-water buffer setup, or a rainwater collection stand without sprawling across the pad. The vertical profile and narrow footprint make it easy to recognize for anyone searching for a slim 100-gallon water storage tank, a narrow vertical poly tank, or a green vertical water tank.
Will it work for your setup?
The tank ships with the fittings shown on the technical drawing on this page: a 2-inch standard bulkhead fitting, a 1-1/2-inch standard bulkhead fitting, and an 8-inch vented manway up top. Each bulkhead seals with its supplied gasket, so match your mating pipe thread to the 2-inch and 1-1/2-inch port sizes and you have a leak-tight connection out of the box. The 2-inch port suits a gravity or pump feed line, and the 1-1/2-inch gives you a second tap for a return, overflow, or level sensor. The vented manway keeps the tank from drawing a vacuum on draw-down and makes cleanout and inspection simple. Dimensions are verified: 63 inches tall by 23 inches in diameter, 100 gallons nominal.
Plan the pad and the weight
Filled with water, this tank carries roughly 834 pounds over that 23 x 23-inch footprint, so the pad or platform under it has to be flat, level, and fully supporting across the whole base — poly tanks want continuous bearing, not point loads on a joist edge. That 834 pounds is the in-service load, not the shipping weight; the tank travels empty, so a light freight quote is exactly what you should expect. If you are sizing the pad, walk through our concrete pad sizing guide before you pour, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 100 gallons matches your draw and refill cycle. For new installs, run a proper hydrostatic acceptance test to catch fitting leaks and pad settlement before the tank goes into service.
The mistake to avoid
This is a water storage tank, not a chemical tank. Sizing it right is the pitfall people hit — a 100-gallon buffer looks generous until a pump runs it dry between refills. Use the sizing calculator to match capacity to your real draw and refill cycle rather than guessing. For grey-water or rainwater aggregation, our water reuse topology guide shows where a tank this size fits in a staged storage train.
