Yes, it IS there, but it is nearly invisible unless looking right at it from close by.  I did not find it until today when I (standing two or three meters from it) complained to a local that the map was wrong.  He said, "yes, it's right there" and pointed.  I still didn't see it until he pushed the button to make water flow!  If I ever go past there with spray paint, I'll make a sign!  :-)
