I am wanting to set up a pump to get water from a very small stream. Before anyone jumps in about if this is allowed I have already checked and allowed to do this. The elevation change is about 80 feet on a fairly steep hillside and the run is about 250'. I have guessed about 5 GPM is about all I could reasonably pump from the creek much of the time. The flow is very dependent on recent rainfall, time of the year, etc and it stops completely in late summer on very dry years.
I had thought of putting a pump at the bottom but running wiring is going to be an issue. Burying it on the irregular hillside is not possible (or at least it doesn't seem practical). I could run overhead but would like to avoid that for visual reasons. I could put a gas pump at the bottom but that would require trips down with gas and to start - it would work but getting others to use it would be difficult.
I am thinking of using a deep well pump type setup with the pump at the top where it would be easy to run wiring and running 2 poly pipes to the bottom. I know its not efficient but it still seems like a reasonable solution. I am wanting to get some feedback on this...
I am also thinking I should have some way to adjust the flow for seasonal variations so I don't over pump when levels are low. Could I just put an adjustable valve on the inlet to the venturi to restrict flow when available water is low?
