I'm not quite sure what it's capacity is, maybe a couple hundred gallons? It is just a plain bucket style tank, I will add a picture. The way the water system works, is we siphon the water from the well via a long 3/4 inch plastic hose, once the siphon gets going it is then connected to another hose that leads into the basement and into the tank. It is a very old school and simple water system.
