Hi Lisa. You would need an inline pump, or a shallow well pump to get pressure if you use tanks. I use shallow well jet pumps with a pressure tank. I know others who simply use a continuous duty jet pump that is inline, no pressure tank, but instead a pressure regulator that is inline.

There are some small inline pumps that work well, and put out about 5 gpm, I think they are Flo tech, and have tiny pressure tanks connected to the pumps.

I imagine a 50-100 gallon tank would be more than efficient for a couple small raised beds, you may have to fill it once a week depending on the crop, weather, and other variables.
