This pump is in our garden. It still functions as a pump of sorts, with water falling into a small pond. We don't, but birds do, drink from it.
The interesting thing about it is that we found it inside the house, in the cellar.
This how we first saw it: it was once the original water source for the house.
If having a drink from a pump like that makes you think "ewww", spare a thought for many parts of the world where they would think it was the height of luxury.
