The Bushman 265 Gallon Slimline Rainwater Storage Tank is built for the property where a round tank simply will not fit. At 25 inches wide and 59 inches long, this green polyethylene slimline tucks flat against a wall, fence line, or between a house and a property line while still delivering a 265-gallon rated capacity in a 62.5-inch-tall profile. If you have been searching for a water storage tank that solves a tight-footprint problem without giving up real storage, this is the slimline configuration that does it.
Will it work for your site?
The tank measures 62.5 in tall by 25 in wide by 59 in long, with a footprint of 25.0 x 59.0 inches - the narrow 25-inch dimension is what lets it sit in spaces a conventional vertical tank cannot. It is molded from polyethylene and rated to a specific gravity of 1.0, which is exactly right for water and rainwater service. Filled to capacity, the tank and its contents reach 2,210 lb (the full water weight and the maximum rated contents weight are the same here, since water is the design fluid). That number matters before you set it: the pad or surface underneath has to carry the full 2,210 lb without settling or tilting. For help confirming that this size matches your roof catchment and demand, run the numbers in our Tank Sizing Calculator and review the Tank Sizing Guide. Inlet, overflow, and outlet fitting configuration is confirmed at order - call 866-418-1777 to verify the connections for your harvesting setup, and see the technical drawing on this page for the tank's outline and dimensions.
Setting it up the right way
A slimline carries more of its weight up high relative to its narrow base, so a level, full-contact foundation is not optional. Because the footprint here is long and shallow (25 by 59 inches), the entire 59-inch length needs continuous support - a slab or compacted bed sized to the full footprint, not a few isolated points. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that base right. For the harvesting side - first-flush diversion, inlet screening, and overflow routing - see Bushman rainwater harvesting tank setup and first-flush diverter sizing. If this tank is part of a larger reuse or fire-reserve plan, the industrial water reuse tank topology and fire-water reservoir design guides cover sizing discipline and freeze protection.
The mistake to avoid
The most common error with a slimline is treating it like a round tank on the foundation. A round vertical tank distributes its 2,210 lb over a wide circular base; this one concentrates that same load along a narrow 25-inch-wide footprint. Skimp on the pad, or let one end sit lower than the other, and a slimline will lean - and a leaning, full tank is hard to correct. Plan a fully supported, dead-level base across the whole 25 x 59-inch footprint from the start.
