The Bushman 2650 Gallon Rainwater Harvesting Tank in Black is a vertical, rotationally molded polyethylene storage tank built to hold and protect collected rainwater for irrigation, fire-reserve, and non-potable household supply. It stands 80 inches tall on a 102" x 102" footprint, giving you a large-volume harvesting vessel that stores 2,650 gallons in a single upright tank. The black exterior blocks light, which suppresses algae growth in stored water — a practical reason harvesting systems lean toward dark tanks rather than translucent ones.
Will it work for your site?
Confirm two things before you build the pad: the loaded weight and the fitting. Filled to capacity, this tank carries roughly 22,101 pounds of water on a 102" x 102" footprint. That load has to sit on a level, engineered base — an above-ground poly tank of this size needs a properly sized concrete pad, and our concrete pad sizing guide walks through the ACI 360R-10 framework for exactly this situation. For plumbing, the connection to plan around is:
- Outlet fitting: 1" NPT bulkhead (per the technical drawing on this page)
Verify that thread and diameter against your first-flush diverter, pump inlet, and overflow line before ordering connectors. To sanity-check the volume against your roof catchment area and rainfall, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Sizing it into a real harvesting system
A 2,650-gallon tank is a serious rainwater reservoir, not a rain barrel — it earns its footprint when it's fed by a correctly sized first-flush diverter and matched to your regional rainfall. Our Bushman first-flush diverter sizing guide (built on the Texas Manual on Rainwater Harvesting, 3rd Edition) and the state-by-state breakdown in Rainwater Harvesting Tank Sizing by State help you match this tank to local regulations and precipitation. If the tank is doubling as a rural fire-water reserve, the NFPA 22 reservoir design guide covers the sizing and freeze-protection discipline that stored-water fire supply demands.
The mistake to avoid
Don't order connectors before you've confirmed the fitting on the drawing. The 1" NPT bulkhead sets what your inlet, outlet, and overflow hardware has to thread into, and mismatched fittings are the most common reason a harvesting install stalls at hookup. A bulkhead seals with a gasket, not the thread alone — confirm the gasket seats cleanly and is appropriate for non-potable water service before you pressurize the line. Match the thread, seat the seal, then plumb.
