Water power pump question

Post: # 93343Post hoomin_erra »

Ok, i was thinking of putting a small water feature in the corner of the garden, but need some intelligent isher to help me out.

The idea is a pond, with a resevoir above which falls onto a wheel, and then down into the pond. All easy so far. Now....

I am wanting the wheel to drive a pump to get water from the pond to the resevoir thus sustaining itself. But not sure on exactly what size pump i would need to pump enough water up to the top to keep the whole system working. And also, what size wheel would be needed.

Anyone got any ideas, or websites??

It's a lovely idea which, unfortunately, won't work. What you've described is a perpetual motion machine. You can certainly use the wheel to drive a pump to lift the water to HELP drive the wheel - but you're also going to have to provide an external form of power to make the whole thing work.
