The Bushman 420 Gallon Vertical Rainwater Harvesting Tank in Mocha is a purpose-built above-ground cistern for collecting and storing captured rainwater at homes, farms, and remote sites. It stands 64 inches tall on a compact 47 x 47 inch footprint, so it fits tight against a wall or in a narrow side yard while still holding a meaningful reserve. The mocha exterior is designed to blend into residential and landscaped settings rather than announce itself. If you are still deciding how much capacity your roof catchment and local rainfall actually justify, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Specifications and fittings
Verified dimensions are 64 inches high on a 47.0 x 47.0 inch footprint. The technical drawing on this page calls out a single 1 inch NPT bulkhead fitting, which is your take-off point for plumbing a spigot or pump feed. If you need a separate overflow or a second draw-off line, plan to add a tee or an additional bulkhead, since the tank arrives with the one tapped port. That 1 inch NPT bulkhead accepts standard 1 inch NPT male threaded fittings, so match your gasket and thread sealant to the line you are running. Filled to its rated 420 gallons of water, the tank carries a full water weight of roughly 3,503 pounds, which means the pad or ground surface underneath has to be flat, fully supporting, and rated to hold that load without settling.
Siting and pad prep
Because a rainwater tank this size concentrates a lot of weight on a small footprint, the base matters as much as the tank itself. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting the foundation right. For catchment plumbing, the first-flush diverter sizing writeup and our state-by-state rainwater sizing breakdown cover the regulations, rainfall math, and hardware that make a harvesting system work rather than just collect water.
The mistake to avoid
The common misstep with a tall vertical rainwater tank is setting it on soil, gravel, or an undersized pad. At about 3,503 pounds full, an uneven base lets the tank lean, stresses the single bulkhead fitting, and can crack plumbing connections. Level the pad, support the entire 47 x 47 inch footprint, and confirm your fitting and gasket material suit the line before you fill.
