The Bushman 1150 Gallon Dark Brown Rainwater Collection Tank is a 1,150-gallon polyethylene rainwater tank built for above-ground harvesting and bulk water storage. It stands 90 inches tall on a 63 x 63 inch footprint, so it holds real capacity without spreading across the yard. The dark brown color is made to sit unobtrusively against a house wall, fence line, or treeline while a full reservoir of rainwater collection sits behind it.
Will it work for your site?
At 1,150 gallons, a full tank of water weighs about 9,591 pounds, which is also its maximum rated contents weight at a 1.0 specific gravity. That number matters more than the gallon figure: it tells you what the pad under the tank has to carry. Nearly five tons sitting on a 63 x 63 inch footprint needs a flat, level, continuously supported base. If you are sizing or pouring that base, the concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. To check whether 1,150 gallons is the right capacity for your roof catchment and demand, run the numbers in the Tank Sizing Calculator and the Tank Sizing Guide.
Fittings and plumbing
The tank comes configured for a rainwater-harvesting plumbing run. Per the technical drawing on this page, it carries three flat fitting pads (an 11" x 10" pad, an 8" x 11" pad, and an 8" x 20-1/4" pad) that give you flexibility on where you land your inlet and accessory penetrations. It also includes a 3-inch outlet and overflow kit and a 1-inch bulkhead fitting in polypropylene with an EPDM seal. That EPDM gasket sets the temperature and service limits on the connection, and the 1-inch polypropylene bulkhead mates to standard 1-inch plumbing, so confirm your fitting and valve threads against the technical drawing before you set the tank and rough in your lines, since the pads also determine where penetrations can be cut cleanly.
Freight and offload planning
An empty polyethylene tank is light, so the install concern is not weight on arrival but clearance: at 90 inches tall and 63 inches wide, plan your offload path and gate, door, or driveway access around those dimensions before delivery day. In cold climates, also plan freeze protection on the 3-inch outlet and overflow lines so standing water in the plumbing does not freeze and split a fitting; the NFPA 22 fire-water reservoir guide covers the freeze-protection engineering for cold-climate service that applies to any outdoor rainwater install.
The mistake to avoid
This is a rainwater collection tank rated at a 1.0 specific gravity, meaning it is sized for water. Do not press it into chemical or heavier-than-water service; that calls for a higher-SG-rated tank, so call 866-418-1777 and we will point you to the right vessel. The other common miss on harvesting systems is skipping first-flush diversion, which keeps roof debris and the dirtiest initial runoff out of stored water. Built in Fairfield, Texas, this tank pairs naturally with our first-flush diverter sizing guide, which sizes that hardware per the Texas Manual on Rainwater Harvesting, 3rd Edition. If the same reservoir is doing double duty for grey-water or HVAC condensate aggregation, the water reuse tank topology guide covers quality-banded storage.
