The Bushman 300 Gallon Water Storage Tank is a vertical polyethylene tank built for reliable above-ground water storage on farms, job sites, rural properties, and residential water systems. It stands 66 inches tall on a 66-inch round footprint, giving you meaningful capacity in a compact, self-supporting profile that fits inside a small enclosure, on a pad, or against a wall run. If you are comparing 300-gallon vertical water tanks or shopping for a Bushman poly water storage tank, this is the workhorse size for hauling, gravity-feed, and buffer storage.
Specifications at a glance
Verified dimensions are 66 inches tall by 66 inches in diameter, holding 300 gallons in a vertical polyethylene body. A full tank of water weighs roughly 2,502 pounds, and the footprint you design your base around is a 66 x 66 inch circle. Fitting and outlet configuration is confirmed at order — call 866-418-1777 to specify bulkhead, gasket, and outlet size for your plumbing rather than guessing at connections.
Does it work for your site?
At roughly 2,502 pounds full, the pad and any platform underneath the tank need to carry that load without settling. Give the full circle of the tank continuous, level support rather than resting it on isolated blocks. For a repeatable way to check the base under a load like this, our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks. Not sure 300 gallons is the right volume for your draw and refill cycle? Run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide before you commit. On a new install, fill and hold the tank with water before you trust it in service so you can watch for pad settlement and confirm the fittings stay dry — our hydrostatic test methodology covers the water-fill discipline and hold-time math for acceptance.
The mistake to avoid
This is a water storage tank. The one error that catches buyers is treating it as a chemical tank: heavier-than-water fluids and aggressive chemistries call for a specific-gravity-rated tank, and that rating is not part of this water configuration. If you are storing anything heavier than water or a chemistry that attacks standard poly, call 866-418-1777 and we will match you to a specific-gravity-rated vertical tank instead. Store water here, match your fittings to a water service, and confirm the drawing details against the technical drawing on this page before you plumb the connections.
