The Bushman 1000 Gallon Vertical Rainwater Harvesting Tank in black is a polyethylene cistern built for residential and light-commercial rainwater capture. It stands 65 inches tall on a 75-inch diameter footprint - a stable, low-profile vertical that holds 1,000 gallons without tip-loading a slab the way a tall, narrow tank can. The black wall blocks light, which keeps algae from growing in stored water - a meaningful detail for anyone harvesting roof runoff for irrigation or non-potable household use.
Will it work for your harvesting setup?
Dimensions and ports are where most people get it wrong, so here are the numbers. This is a 1000 gallon vertical tank measuring 65" high on a 75.0" diameter footprint - check your gate, doorway, and slab form against that before delivery. For connections, the tank distinguishes uncut flat pads from supplied plumbed fittings: the 10" x 12", 8" x 11", and 9-3/8" x 20-1/4" flat areas are flat-fitting blanks you locate and drill yourself for your inlet, screen, or vent. The supplied connections are a 3-inch outlet/overflow kit and a 1-inch bulkhead fitting in polypropylene with an EPDM seal. See the technical drawing on this page for exact port placement before you trench or plumb.
Overflow, weight, and the slab
The included overflow kit is sized at 3 inches - check that against your roof's peak inflow, because in a hard rain event your catchment can deliver more than your draw, and an undersized overflow backs water up the downspout. Size your first-flush diverter and overflow to your roof area, not to the tank. Then think about the load: filled to 1,000 gallons, this tank carries 8,340 pounds of water on that 75-inch diameter footprint - over four tons on a roughly 6-foot circle. That number, not the empty weight, determines your pad. Pour or verify a level, load-rated base before delivery; a tank set on uneven ground or undersized fill will stress the wall over time. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to match capacity to your annual rainfall and demand, and use the concrete pad sizing framework to spec the base under that 8,340-pound load.
One mistake to avoid
This is a rainwater harvesting tank rated to a specific gravity of 1.0 - it is built for water, not for fertilizer concentrates, chemicals, or any liquid denser than water. The supplied bulkhead seal is EPDM, which holds up well for water and rainwater but not for petroleum or oils, and a heavier-than-water contents load exceeds what the wall is rated to carry. Don't repurpose this tank for chemical storage. For sizing the harvesting system itself - catchment area, first-flush diversion, and storage targets - the Bushman first-flush diverter sizing guide and the state-by-state rainwater sizing guide walk through it with real numbers.
