The Bushman 730 Gallon Low Profile Vertical Rainwater Collection Tank in Mocha is a polyethylene water storage tank built for sites where headroom is tight and a wide, stable footprint matters more than height. At 730 gallons in a 74-inch-wide body that stands only 55 inches tall, this low profile vertical tank needs roughly 55 inches of vertical clearance plus room for lid and fitting access, so it tucks under eaves, decks, and overhangs that a taller water storage tank can't clear. The earthy Mocha color helps it blend into residential and rural settings, and it's a practical fit for rainwater harvesting, irrigation reserve, and general bulk water storage.
Will this tank work for your site?
This tank holds 730 gallons and measures 55 inches tall by 74 inches wide by 74 inches long, giving a 74.0 x 74.0 inch footprint. It's molded from polyethylene with a specific gravity rating of 1.0, which means it's rated for water and water-weight liquids only - water sits right at that 1.0 line, so a rainwater or stored-water application is a correct match. Anything denser than water, including most chemical solutions, fertilizers, and brines, exceeds the 1.0 SG rating and is not supported by this tank. Filled to capacity, the contents weigh 6,088 pounds, so plan your base accordingly: a low profile vertical storage tank loads its full water weight across that 74-inch footprint, and the pad underneath has to carry all of it. For setting that base correctly, see our concrete pad sizing guide, and use the Tank Sizing Calculator with the Tank Sizing Guide to confirm 730 gallons covers your draw between rain events.
Fittings and plumbing
The tank comes with a 1-inch bulkhead fitting (part 60427), which accepts standard 1-inch NPT pipe and valves at the outlet. A bulkhead seals against the tank wall with a gasket, and that gasket is what keeps the connection from weeping over time - so keep the area around it supported and free of side load. For exact fitting placement and dimensions, see the technical drawing on this page.
Sizing rainwater and reserve correctly
For rainwater capture, the size that matters is how much you can bank between storms versus how fast you draw it down. Our guide to first-flush diverter sizing walks through keeping the initial dirty runoff out of stored water, which is the single most useful upgrade for a collection tank like this one. If you're banking water for irrigation, fire reserve, or grey-water and condensate reuse, the fire-water reservoir design guide and our water reuse topology guide cover how a single low profile vertical storage tank fits into a larger banked-storage train.
The mistake to avoid
The common error with a wide, short tank is treating the pad as an afterthought. Full, this 730-gallon Bushman spreads 6,088 pounds across its 74 x 74 inch base - roughly 1.1 psi of average bearing pressure - and an uneven or undersized pad lets the tank settle and stress the bulkhead fitting at the outlet. Build the base to carry the full rated 6,088-pound contents weight, keep it dead level, and support the entire footprint, not just the perimeter.
