The Bushman 2500 Gallon Black Rainwater Collection Tank is a vertical polyethylene cistern built to capture and hold harvested rainwater for irrigation, livestock, fire reserve, and general non-potable supply. It is rated for a specific gravity of 1.0, meaning it is engineered for water and water-density contents, so it serves as a true water and rainwater tank rather than a vessel for anything heavier than water. The black shell blocks light, which suppresses the algae growth that plagues translucent or light-colored tanks holding stored rainwater. It holds 2,500 gallons in a 96-inch diameter footprint and stands 95 inches tall, staging a large volume on a compact pad. This is the Bushman rainwater tank platform buyers search for under terms like black water tank and 2500 gallon rainwater storage.
Will it work for your site?
Filled to capacity, the stored water weighs 20,850 pounds, and the maximum rated contents weight is the same 20,850 pounds. That full-water figure is the number your foundation has to carry, so plan the pad before the tank arrives. For pad design, see our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide, and use the Tank Sizing Calculator with the Tank Sizing Guide to confirm 2,500 gallons matches your catchment area and draw schedule.
Fittings and connections
This tank arrives plumbing-ready and stays configurable to your layout. The 4-inch outlet and overflow kit (KIT TK OUTLET OVERFLOW 4IN) handles drainage and overflow protection, and the 1-inch bulkhead fitting (RFTG 1IN BH PP/EPDM) gives a sealed penetration for a feed or gauge line with a polypropylene body and an EPDM gasket as the seal material in contact with the stored water. Three molded flat fitting areas (12" x 14", 8" x 14", and 12" x 24") act as field-adaptable mounting pads where additional bulkheads or inlets can be located to suit your plumbing run. Confirm inlet, outlet, and overflow placements against the technical drawing on this page before you cut or install anything.
Rainwater harvesting setup
For a clean catchment system, pair this tank with first-flush diversion sized to your roof area. Our guide on Bushman Rainwater Harvesting Tanks: First-Flush Diverter Sizing per the Texas Manual on Rainwater Harvesting walks through diverter sizing. If you are aggregating multiple water streams, the Industrial Water Reuse Tank Topology guide covers grey-water, rainwater, and HVAC condensate storage trains. Holding rainwater for rural fire protection? The Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and cold-climate freeze protection.
This tank ships LTL freight from Fairfield, TX, with freight quoted live to your ZIP. Get your exact number with the Freight Cost Estimator, or call 866-418-1777 to confirm delivery access and forklift or strap handling for a 96-inch-diameter unit. The most common mistake on a tank this size is underbuilding the foundation: footprint is 96 x 96 inches and the unit stands 95 inches tall, so the pad must be level and rated for the full 20,850-pound loaded weight, not the empty shell.
