I'm pretty sure it hold 250 gal. We bought it at a yard sale for $40. It was already fitted with a faucet for a hose, because the people had used it to haul water for the brick layers to use while building their house, since they weren't connected to a water system yet.
It may be worth mentioning, that the gravity factor is ultimate when setting up your system. I used cement blocks and went 5 high thinking this would be plenty high enough. As fate would have it, the place I put it (basically out of sight from the front of the house) is where the ground slopes down some and I cannot use the hose to water on the opposite side of the yard as it is actually higher then the faucet on the rain barrel. When you are contemplating height in setting up a gravity system, remember that the height of the faucet is the important measurement, not the height of the barrel itself! I learned that the hard way. I am draining off the water now and watering everything so I can rebuilt the platform higher before we get our spring rains.
Another bonus in having the rain barrel is when the power goes out.... no pump, no well water. We can fill buckets with water and bring water in to fill the toilet tank so we can flush. That's a real plus out here in the country where we are not a first priority with the power company in getting the power back on.
