Nancy, I'd be looking at 18 m of head at the worst with the longest run being 130-150 meters. I'm looking for "creative" ideas if possible. Love the peristaltic pump idea. I would be tearing apart and rubberizing all the seals if I used an old motor someone has laying around. I got the idea from someone here that made a fountain pump out of a 2-stroke mower and small wind wheel. The heads would require extensive reworking to make a 4-stroke work. Could be out of my depth, but I'm willing to try.
Jay, To be clearer, I'd be making the dry creek beds with a lot of clay, field rock, and the John Deere. They would be dry when runoff isn't traveling from one pond to another. John W. is right in that I'm looking to collect winter runoff and then be able to refill in times of drought. One of the other big reasons for these smaller ponds is to create a wildlife area and a Duck habitat for my layers. My ground is almost all sloped prairie with 3-12% grade sloping in one general direction. Soil runoff is a problem in spots. I've done some work to control the worst of it, but haven't put a bigger plan into place. Trees are slow and affect the prairie look we've come to love (we have ~200 trees on 7 acres as it is).
John W., Thanks for the reference! I have some of this material already on the farm.
John D., These were the approaches I initially thought of. I've maintained both types in years past at other people's farms before I could get my own. I've spent most of my career as an engineer of types and love a good Rube Goldberg machine. Working metal, wood, plastic, glass, electronics, cnc programming, etc. is all stuff I've comfortable with.
The Venturi effect? Like with compressed air?
Thanks everyone for the responses! Super excited to get going on this project!
