Melingriffith Water Pump

Taken while out for a run - I always go past this water pump, which was restored recently: http://www.bbc.co.uk/news/uk-wales-13999352 but I never see it in operation. There is a seating area in front but it's always locked so had to take this photo from behind bars.
There's quite an interesting history about Melingriffith, a village that has disappeared really and been subsumed.
