Thanks folks for the links - now all I have to do is translate it into UK
equivalents (I don't think we have these rubbermaid tanks over here!


I took the basic concept but used a hole in the ground with liner instead of
a tank. The pipe goes on top of the liner to the bottom, not through the
liner. The output flows into a stream to the pond. Works great.
