Title says it all. I am looking for a submersible water pump, a few
litres an hour would do, driven by propeller/turbine working off the flow
in the stream to pump water up a few feet. Or of course any relevant
components of this idea would be useful. Many thanks for your thoughts.
Water wheel, unless on a raft, is no use as water lever varies about 5000%
of minimum 100mm or so.

Sir might want to look at this old, but effective concept

Sir may also like to get some ear defenders if he uses one...

But if it's submerged in a stream at the bottom of the garden, who
cares ?



Lots of food for thought there, many thanks to everyone who replied.
What I want is a small, unobtrusive installation that just trickle feeds
a flower bed on top of a retaining wall, so I can grow water's edge
plants on top of it. I will report back when I implement a solution.
