The Bushman 125 Gallon Vertical Rainwater Harvesting Tank in black is a polyethylene rainwater tank built for above-ground harvesting, standing 50 inches tall on a compact 30 x 30 inch footprint. The black wall blocks light to suppress algae growth in stored rainwater, and at 125 gallons it suits residential roof-runoff capture, garden and landscape irrigation, and supplemental supply where a slim 30-inch diameter has to fit against a wall or in a side yard. Whether you searched "bushman," "vertical tank," or simply "black water tank," this is a purpose-built rainwater unit, not a repurposed stock tank.
Will it work for your install?
The tank is rated for a specific gravity of 1.0, which covers water and rainwater only. Filled to capacity it holds roughly 1,042 pounds, so the base under it carries that load on a 30 x 30 inch footprint — about 167 pounds per square foot of sustained bearing across the 6.25 square foot base. That sits well within a standard 4-inch concrete pad, but above what bare or settling soil reliably holds, so pour or place a level, full-bearing pad before filling. A 50-inch-tall tank on an uneven or undersized base is the most common avoidable failure with above-ground polyethylene. For pad bearing, see our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide, and use the Tank Sizing Calculator with the Tank Sizing Guide to confirm 125 gallons matches your roof catchment and rainfall. Because it is rated to specific gravity 1.0, storing anything heavier than water requires a higher-rated tank — call 866-418-1777 and we will point you to a 1.5 to 1.9 SG-rated equivalent.
Fittings and harvesting setup
The technical drawing on this page shows the fitting layout: two molded flat pads (8" x 7" and 8" x 6") where an installer can land an added inlet, level gauge, or sensor without cutting into a curved wall, plus a 3-inch outlet and overflow kit and a 3/4-inch bulkhead fitting. That bulkhead uses a polypropylene body with an EPDM gasket, which is well matched to water and rainwater service — do not run petroleum-based liquids through the EPDM seal. The overflow path matters for rainwater work, since a harvesting tank should be plumbed to shed surplus during heavy storms rather than back up into your downpipe. Pair the inlet with a first-flush diverter so the dirtiest initial runoff bypasses the tank; our Bushman first-flush diverter sizing guide walks through diverter volume per the Texas Manual on Rainwater Harvesting, 3rd Edition.
Sizing rainwater capacity to your state
A 125-gallon tank is a starting block for harvesting, and the right total capacity depends on your roof area, local rainfall, and how you intend to use the water. Our Rainwater Harvesting Tank Sizing by State breakdown ties capacity to regional regulations and rainfall so you can decide whether one tank or a linked set fits your site. If this tank is part of a rural water-supply or fire-reserve plan, the Fire-Water Reservoir Tank Design guide covers the sizing discipline and freeze protection that rainwater storage in cold climates needs.
This tank ships LTL freight from the plant in Fairfield, Texas, with freight quoted live to your ZIP code. Because a 50-inch-tall, 30-inch-diameter tank ships by LTL and freight scales with distance from Fairfield, buyers in the Northeast or West should pull a live ZIP quote before assuming the list price is the freight cost. Get your freight cost with our Freight Cost Estimator, or call 866-418-1777 and we'll quote it for you. Listed before freight, the Bushman 125 Gallon Black Rainwater Tank is ready to ship.
