The 500 Gallon Slimline Water Storage Tank from Bushman is a vertical storage tank built for sites where floor space is tight but capacity still matters. At 29 inches wide and 69 inches long, its slim footprint tucks against a wall, into a side yard, or along a utility run where a round tank of the same volume would not fit — while standing 78 inches tall to hold the full 500 gallons in black polyethylene, whose opacity blocks light and helps resist algae growth in stored water. If you are matching a tank to an available space or a target volume, the Tank Sizing Calculator and Tank Sizing Guide help you confirm the fit before you commit.
Will it work for your site
This is a vertical storage tank rated at 500 gallons, measuring 78 inches high by 29 inches wide by 69 inches long. The narrow 29 x 69 inch footprint is the whole point of the slimline design — real volume in a shape that fits where a conventional round tank cannot. It is spec'd for water storage at roughly the specific gravity of water (SG about 1.0); it is not rated here for chemical or heavier-than-water service, so keep it to potable water, rainwater capture, and reuse duty. Dimensions are verified against the launch spec, and the technical drawing on this page shows the tank's profile plus the outlet and fitting configuration, so you can plan clearances, plumbing runs, and overhead fill space.
Plan the pad and the loaded weight
Filled with water, this tank carries about 4,170 pounds across a 29 x 69 inch footprint — an average bearing load near 2.1 pounds per square inch, concentrated by the tall, narrow profile that raises the center of gravity above a squat round tank. That load has to land on a flat, fully supporting base: a level concrete pad or a continuously supported surface, never bare soil or a partial cradle. For sizing and reinforcing that pad, see our guide on concrete pad sizing under the ACI 360R-10 framework. Weighing a tall slim vertical against a horizontal layout for a larger install? The tradeoffs are in vertical vs horizontal water-storage tank tradeoffs.
The mistake to avoid
Under-building the base is the failure that shows up months later, not on day one. Anchor and support the tank across its full footprint, keep the base continuous, and account for the roughly 4,170-pound loaded weight and elevated center of gravity when you pour or select the pad.
