The Bushman 250 Gallon Vertical Rainwater Harvesting Tank (BM-30225) is a compact, freestanding catchment vessel sized for residential and light-commercial rainwater capture. It stands 66 inches tall on a 36 x 36 inch footprint, holds a nominal 250 gallons, and is molded from polyethylene in green to blend into a yard or building line. Whether you are buffering roof runoff for irrigation, building out a Texas rainwater harvesting system, or staging a vertical water tank for a remote site, this Bushman 250 gallon tank is configured for the job.
Will this tank work for your site?
Filled to capacity, this tank carries roughly 2,085 pounds of water, so size your pad for the full rated contents weight, not the empty shell. Over the 36 x 36 inch (9 square foot) footprint, that works out to about 232 pounds per square foot of bearing load - the number you actually need before you pour or frame a base. The footprint makes it straightforward to set on a level pad against a wall or under a downspout, and the tank is rated to a specific gravity of 1.0, matching water-density service: rainwater, fresh water, and irrigation supply. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground polyethylene tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 250 gallons is the right capacity for your rainfall and demand.
Fittings and rainwater-harvesting hardware
This tank is configured for harvesting service. Per the technical drawing on this page, it carries two flat fitting pads (8" x 7" and 8.5" x 6"), a 3-inch outlet and overflow kit, and a 1-inch bulkhead fitting with PP/EPDM hardware. The two flat pads are factory-provided mounting landings - not pre-cut ports - giving you clean locations to add an inlet strainer, a level gauge, or a second bulkhead, drilled and sealed in the field; confirm placement against the drawing before you cut anything. The EPDM gasket at the 1-inch bulkhead suits the rainwater and fresh-water service this tank is rated for at SG 1.0, but do not assume that hardware carries over if you later repurpose the tank for any chemical. For first-flush diverter and inlet-screening setups, our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting covers how to keep debris out of stored water. If this is part of a rural water-supply or fire-reserve plan, see our fire-water reservoir design notes on NFPA 22 sizing and freeze protection.
One mistake to avoid
The most common error on a vertical rainwater tank like this is plumbing the overflow undersized or downstream of the inlet. During a heavy storm, your inlet flow can exceed your draw, and an undersized overflow lets water back up into the diverter and inlet. Use the 3-inch overflow that ships with this tank, route it to daylight or a soakaway at full diameter, and keep it independent of the draw-off line. Match your fitting and gasket hardware - this tank uses PP/EPDM at the 1-inch bulkhead - and confirm capacity for your region using the state-by-state rainwater harvesting sizing guide.
