The Bushman 3000 Gallon Rainwater Collection Storage Tank is a polyethylene above-ground tank built for harvesting and holding captured rooftop runoff at residential and light-commercial scale. It stands 113 inches tall on a 96 by 96 inch square footprint, holds 3,000 gallons, and is finished in Mocha to blend into landscaping and shade the water column against algae growth. Whether you are building out water storage, sizing a rainwater catchment, or setting a fire-water reserve, this is one of the workhorse sizes in the Bushman line.
Will it work for your site?
The tank carries a 1.0 specific gravity rating, which matches it to water and other contents at water density. Filled to capacity with water it weighs 25,020 pounds, and its maximum rated contents weight is the same 25,020 pounds, so plan your pad and base for that full load. This tank is rated to water density only; for liquids heavier than water, a higher-SG-rated tank is required. Pour or set a level, fully supporting foundation under the entire 96 by 96 inch footprint before you fill, since an unsupported or out-of-level base is the most common way these tanks get damaged. Measure your access before delivery too: the 8-foot square base and over-9-foot height set your pad dimensions and your door, gate, and overhead clearance, so verify the delivery path and overhead obstructions like eaves and lines. For pad detail, see our concrete pad sizing guide, and to confirm 3,000 gallons is the right capacity for your catchment area and demand, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Fittings and plumbing
Per the technical drawing on this page, this tank is configured with three flat fitting pads (a 12 inch by 14 inch, an 8 inch by 14 inch, and a 12 inch by 24 inch flat) that give you placement options for inlets, sensors, and accessories. It also includes a 4 inch outlet and overflow kit and a 1 inch bulkhead fitting with a polypropylene body and EPDM seal. The 1 inch PP/EPDM bulkhead makes a natural level-sensor or small-line tap, while the flat pads stay open for adding your inlet and accessories. Plumb the 4 inch overflow to daylight or to drainage sized to match or exceed your peak inlet flow, so the tank cannot pressurize or back the runoff up into your gutters during a heavy storm event. Confirm fitting locations and elevations against the technical drawing before you set the tank, because rotating it after placement to chase a plumbing run is far harder than planning the orientation up front.
Rainwater harvesting setup
To get clean storage, pair this tank with a first-flush diverter ahead of the inlet so the dirtiest initial runoff bypasses the tank. Our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting walks through the calculation. If your collected water is destined for grey-water blending, HVAC condensate aggregation, or a wider reuse train, the industrial water reuse tank topology guide shows how to band storage by quality. For rural fire protection, where a rainwater reserve doubles as a private fire-water supply, the fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection.
