The Bushman 330 Gallon Black Vertical Water Storage Tank is a polyethylene vertical water tank built for above-ground bulk water storage where you need real volume without a sprawling footprint. It stands 63 inches tall on a square 41 x 41 inch base, so a full 330 gallons sits in a compact column rather than a wide pad. The black resin blocks light into the tank, which is why most growers, ranchers, and rural property owners pick it for outdoor water storage, irrigation supply, and rainwater storage.
Will it work for your install?
This is a 330-gallon vertical storage tank with a 1.0 specific gravity rating, meaning it is engineered for water and water-weight liquids (specific gravity up to 1.0). Filled to capacity, the contents weigh 2,752 pounds, so plan your stand or pad for the full max rated contents weight of 2,752 pounds bearing on that 41.0 x 41.0 inch footprint - not the empty tank weight. That works out to roughly 1.64 psi of uniform bearing across the 1,681-square-inch base, a useful number for slab design under the ACI 360R-10 pad sizing guide. The tank ships with a 12-inch lid (part 64323) for fill and inspection access and a 2-inch bulkhead fitting (part 63481) for outlet plumbing. Before you cut any pipe, confirm on the technical drawing on this page whether the lid is threaded or slip-on and what thread the 2-inch bulkhead uses (NPT vs. buttress), and remember that a polyethylene bulkhead is only watertight when its supplied gasket is seated and the backing nut is torqued evenly. If you are still deciding between sizes, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide.
The mistake to avoid
The 1.0 specific gravity rating is the line that trips people up. This tank is rated for water and liquids at or below 1.0 SG. If you are storing anything heavier than water - most fertilizers, brines, or chemicals run above 1.0 - this Black water tank is the wrong spec: call 866-418-1777 and we will match you to a 1.5 or 1.9 SG-rated tank in a comparable footprint. The other gotcha is the outlet height: the single 2-inch bulkhead sits at the height shown on the drawing, not at the absolute floor of the tank, so a few gallons of dead volume remain below it - plan for that when you think about full draindown, sediment flush, and winterizing. And size your foundation for the loaded weight, not the empty shell: 2,752 pounds on a 41-inch square base is a real point load, and a tank that settles or leans will stress the 2-inch bulkhead over time. For rainwater capture, our Bushman first-flush diverter sizing guide walks through the inlet side.
Cold-climate service
A 63-inch vertical column of standing water with one low outlet is a classic freeze risk: the tall water mass holds cold and the single drain can ice off below the bulkhead. For winter standing service, drain the tank down or heat-trace it - our fire-water reservoir and freeze-protection guide covers the engineering for cold-climate polyethylene storage.
