Water fountain

Today's picture: Water fountain

Below's picture is of a water fountain in Darling Harbour (Sydney). It's been in the city since I was a child. It's interesting design: half has triangle points for you to step on and the water will flow down. There's also one non-water foot path to walk to the centre.
There's more water fountains for children to play in these days. But makes me wonder how clean the water is.
