The 528 Gallon FatTank With Strainers from ThinTanks is a vertical water tank for sites where floor space is tight but stored volume still has to be real. It holds 528 gallons in a slim upright footprint of just 29.53 x 59.04 inches and stands 77.56 inches tall, so it tucks against a wall, into a utility alcove, or along a narrow equipment run where a round tank of the same capacity would never fit. Empty it weighs 298 lb, carries a 1-inch outlet, and includes the integral strainers that give the model its name and keep debris out of the outlet on rainwater capture, transfer, and reservoir duty.
Will it work for your water?
This tank is rated for a specific gravity of 1.0, exactly the density of fresh water, so a full 528 gallons of water is the right and complete duty for it. Size your pad and supports around the loaded weight, not the empty shell: at capacity the water adds 4,404 lb, and with the 298 lb tank that puts roughly 4,702 lb on the foundation every day. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 528 gallons matches your draw-down and refill cycle before you commit. It is rated to 120°F / 48°C, which covers ambient and warm-climate service but not hot-water or heated-process duty above that ceiling. Certification references 2282 and 2285 are listed for this model. One planning note on the 77.56-inch height: the strainers and fill point sit better than six feet up, so budget for a ladder or platform at the fill access point.
The mistake to avoid
The SG 1.0 rating is the line to respect. This is a water tank, and its wall thickness is sized for water-weight loading. Do not press a 528-gallon FatTank into service for a heavier liquid such as a fertilizer or brine with a specific gravity above 1.0 without moving to a tank rated for that density, because the same volume of a denser fluid pushes the wall past what this shell is built to hold. Keep it on water and it will run for years. If you are sizing storage for private fire protection, our guide on fire-water reservoir tank design and NFPA 22 sizing walks through reserve volume and freeze protection, and the concrete pad sizing framework covers the foundation under that roughly 4,702 lb load.
Freight
This tank ships LTL freight from Texas, quoted live to your ZIP code. Enter your delivery ZIP in the Freight Cost Estimator for a rate to your door, or call 866-418-1777 and we will handle the sizing and the freight quote together. For rainwater-capture setups, our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting pairs well with the strainer-equipped 528-gallon FatTank.
