I had been going to suggest a ram when I saw this thread, but I see it has been well covered (oops, the bit of the brain that engages puns has got involved, sorry). My grandfather's house had had one, installed by the previous occupant, an employee of a big house, without permission. The employer had sacked the employee and disconnected the ram. It ran off quite a small stream (creek).

I wonder if some of the discussion is relevant to me. I'm in a terrace, and all the roof water runs off at the ends, so I can't harvest it. The flagged area all runs towards the back door, and I have started digging a hole in which to sink the old cold water tank. This is about 2 1/2 feet diameter and about 2 foot deep. The idea is that this catches the run off which I can then use for watering. I have a small battery powered pump to get it out.

However, it has occurred to me that I could also run the water through a small fake stream down the side of the garden, by pumping it up that 2 foot, and across the garden about four yards up a slight slope - maybe another 6 inches. And I would like to do this using solar power. Is that possible?

And could Bobert use solar to move that water of his?
