The Bushman 205 Gallon Vertical Rainwater Harvesting Tank (SKU 45420) is a black polyethylene above-ground cistern built to catch, hold, and dispense collected rainwater on a compact footprint. It stands 60 inches tall on a 35 x 35 inch base, so it fits tight against a wall, downspout, or the corner of a shed while still banking a meaningful 205 gallons between rain events. The black wall color is deliberate for harvesting duty: it blocks light and discourages algae growth inside the tank.
Will it work for your rainwater system
This is a vertical storage tank rated at 205 gallons, measuring 60 in high by 35 in wide by 35 in deep (dimensions verified against the drawing on this page). The tank carries a single 1" NPT bulkhead fitting per the technical drawing, which seats through the tank wall with a gasket on the inside and gives you a clean threaded connection point for a spigot, hose bib, or pump feed. Confirm your mating hardware is 1" NPT threading into that bulkhead. Because this is the only factory penetration on the tank, any additional connection you add in the field needs its own bulkhead and gasket, not a self-tapping fitting. Size your catchment against your roof area and local rainfall before you commit to a single tank — the Tank Sizing Calculator and Tank Sizing Guide walk through the math, and Rainwater Harvesting Tank Sizing by State ties it to your region's rules and rainfall. If you plan to run a first-flush diverter, the first-flush diverter sizing guide covers how to keep the initial dirty runoff out of your stored supply.
Plan the pad before it arrives
Filled with water, this tank carries roughly 1,710 pounds over that 35 x 35 inch footprint — about 1.4 psi of bearing pressure across the base, on top of the tank's own dead load. That figure reflects water at a specific gravity of 1.0, which is what this tank is spec'd to hold. That load has to land on a flat, fully supported, level base: bare soil that settles or a pad that only catches part of the bottom will stress the wall over time. Pour or set a pad that supports the entire footprint. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework so your foundation matches the loaded weight. The mistake to avoid here is siting the tank first and thinking about the base second: with over three-quarters of a ton of water bearing down, the pad is not optional.
Cold-climate service
If this tank will sit through freezing winters, plan for it up front. Our freeze-protection engineering guide covers how to keep stored water usable in cold weather and how polyethylene tanks hold up through the freeze-thaw cycle.
