The 793 Gallon ThinTank With Strainers from ThinTanks is a vertical water tank built for tight-footprint bulk storage where a round tank simply will not fit. Its slim profile measures 22.83 inches deep by 117.32 inches wide and stands 77.56 inches tall, so it slides against a wall, into a narrow side yard, or along a garage run while still holding 793 gallons. Empty it weighs 385 pounds and carries a 1.0 specific gravity rating, which suits it to fresh water, rainwater capture, and general non-pressurized water storage. It ships with strainers and carries certifications 2282 and 2285.
Will it work for your site?
This is a low-profile answer to the classic space problem: a 793-gallon vertical tank without the diameter of a standard round tank. The narrow 22.83-inch footprint is the whole point, so confirm your pad or slab spans the full 117.32-inch length and that the ground is level and continuously supported edge to edge. The tank includes a 12-inch lid for fill and inspection access plus a 1-inch outlet. It is rated to a maximum service temperature of 120°F / 48°C, so keep contents below that ceiling. For the full port layout and slot dimensions, see the technical drawing on this page before you plumb it.
Plan for the filled weight
Water is heavy, and a slim tall tank concentrates that load. Filled to capacity this ThinTank carries roughly 6,614 pounds of water on a 22.83 x 117.32-inch footprint. Set it on an engineered pad sized for that load, not on bare or sloping soil. For a walkthrough of pad thickness and reinforcement, read our guide to concrete pad sizing for above-ground polyethylene tanks, and if you are still settling on capacity, run the numbers with our Tank Sizing Calculator and Tank Sizing Guide.
The mistake to avoid
The specific gravity rating on this tank is 1.0, which means it is engineered for water. Do not repurpose it for a heavier liquid such as a fertilizer or chemical concentrate with a specific gravity above 1.0; the tall thin wall is designed around water's weight, not a denser fluid, and a heavier product calls for a tank rated for that specific gravity. If your use is rainwater harvesting, our first-flush diverter sizing guide covers the upstream plumbing.
