What a coincidence. My yoga teacher just turned me on to "Art of Fermentation" last week. I rushed out and got a copy and am about a third of the way through. I love the concept of Biophilic Consciousness and how you express that idea throughout the book. I had started to become afraid of bacteria over the last few years as so much anti-bacterial propaganda has been forced upon us, but now I realize that I can just relax and not worry about it and start to love the little critters!

I'm glad Brad stepped in here. You definitely need to consider the actual lift requirement. You also mentioned that your spring feeds a hole that you dug. How quickly does the spring fill the hole and what are the chances of the hole being emptied too quickly by the pump? (No water = burned out pump!) You might need a float switch to cycle the pump on/off based on the water supply. And if that were the case, I'd probably put a couple of batteries (two 12v in series) down there by the pump.
