The 528 Gallon ThinTank with Strainers is a vertical water tank built for sites where floor space is tight but capacity still matters. At just 18.5 inches deep and 94.49 inches wide, its slim 18.5 x 94.49 footprint lets it stand against a wall, in a narrow equipment alley, or along a fence line where a round tank of the same volume would never fit. It stands 77.56 inches tall, holds 528 gallons, and ships from Texas with an empty weight of 298 pounds. Integrated strainers keep debris out of the stored water at the fill points, and the tank carries certifications 2282 and 2285 - confirm those cover your specific application before you commit.
Will it work for your site?
This is a 1.0 specific-gravity tank, rated for water and water-weight liquids up to a contents density of 1.0 - the standard band for water storage, rainwater, and process or reuse water. Filled to 528 gallons, the water alone weighs 4,404 pounds, and that full water weight is also the maximum rated contents weight. Add the 298-pound empty tank and you are planning the slab and any anchoring around 298 + 4,404 = roughly 4,702 pounds full. The tank carries a single 1-inch outlet and is rated to a maximum temperature of 120 F (48 C), so keep it out of hot streams and size your plumbing to that 1-inch draw. Because the ThinTank is a tall, narrow profile, a level, full-footprint pad and proper wind restraint matter more than on a squat tank - our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground tanks. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 528 gallons covers your draw, and check the technical drawing on this page for exact port and lid placement before you plumb it.
Common water-storage uses
The thin footprint makes this 528 gallon size a natural fit for rainwater harvesting against a building wall, grey-water and HVAC-condensate reuse trains, and rural fire-water reserve where the reservoir has to tuck into a limited yard. Keep the single 1-inch outlet in mind for fire service - it is a real throughput limit, so plan draw and refill around it. If you are stacking reuse-quality bands or sizing a private fire reserve, the water reuse tank topology guide and the NFPA 22 fire-water reservoir guide cover the sizing discipline. For rainwater specifically, first-flush diverter sizing is worth reading in our rainwater harvesting guide.
The one thing not to skip
A tall, slim tank is far more sensitive to a poorly prepared base than a wide one. Do not set a ThinTank on gravel, blocks, or an undersized pad - the full-footprint, level slab under the entire 18.5 x 94.49 base is what keeps the sidewall from flexing and the tank from tipping when full. Get the pad right first, then fill it.
