The Bushman 1150 Gallon Plastic Vertical Water Storage Tank in Mocha (SKU BM-30752) is a 1,150-gallon polyethylene vertical tank standing 90 inches tall on a 63-inch diameter footprint. It is built for above-ground bulk water storage - rainwater harvesting, fire-water reserve, irrigation, and industrial water reuse - where you need real volume in a single compact column. The mocha exterior keeps the contents shaded and the tank visually low-key against a building or treeline.
Will this tank do the job
This is a vertical water storage tank, so it stores liquid at atmospheric pressure and drains under gravity. The polyethylene wall carries a specific gravity rating of 1.0, which matches plain water - the right and intended use for this tank. Filled to capacity, 1,150 gallons of water weighs 9,591 pounds, and that is also the maximum rated contents weight, so the tank is sized to hold a full column of water and nothing denser. At 90 inches (7.5 ft) tall, plan overhead clearance for the fill inlet and lid access - it will not slide under a standard 7-foot door header or a low eave. If you are deciding between this and an adjacent size, the Tank Sizing Calculator and the Tank Sizing Guide walk you through matching capacity to your demand and refill rate.
Water only - mind the specific gravity ceiling
This wall is rated to specific gravity 1.0, which means water and water only. Do not put any liquid heavier than water in it - fertilizer solutions, brine, or chemicals with a specific gravity above 1.0 will exceed the wall rating and need a 1.5- or 1.9-rated tank instead. Treating the SG rating as a hard ceiling rather than a suggestion is the difference between a tank that lasts decades and one that bulges or fails early. Fitting and outlet sizes and positions are confirmed at order, so call 866-418-1777 before you plumb in to match your inlet, outlet, and overflow to the layout you need.
Foundation and the mistake to avoid
The single most common mistake on a tank this size is the pad. Nearly five tons of water on a 63-inch (5.25 ft) diameter circle means the contents load has to land on a flat, level, fully-supporting base - not gravel humps, not a partial ring, not bare dirt that will rut after the first rain. Pour the pad larger than the tank footprint: a minimum 6-foot square or 6-foot round slab gives you full edge bearing under the entire floor. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework so the slab carries the load without cracking or tilting the tank. Get the foundation right and this tank serves for decades; get it wrong and you stress the floor knuckle from day one.
How it fits your water system
Because it is a Bushman vertical storage tank, it slots cleanly into rainwater and reuse setups. If you are harvesting roof runoff, the Bushman rainwater harvesting and first-flush diverter guide covers sizing the diverter ahead of the tank. For grey-water, condensate, or blended reuse trains, the industrial water reuse topology guide shows where a 1,150-gallon vertical tank lands in the train. Running it as a rural fire-water reservoir, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
This tank ships LTL freight from our Fairfield, Texas plant, palletized as a single oversized pallet and quoted live to your ZIP - because it ships from one plant, freight scales with distance, so pull a number before committing with the Freight Cost Estimator, or call 866-418-1777 to lock in delivery and confirm offload at your site. We will help you size the right tank and route the freight before you buy.
