Yard hydrands, like fire department hydrants. Very often,
there is a controlling rod, the actual valve is below the
frost line. There shoul d be a drain on the bottom. When the
valve is closed, the water within the vertical pipe drains
into the ground.

It's probably a frost free hydrant. The water lines
should be
buried below the frost line. Your footing probably is too.
I live in
southeast Nebraska. The frost line is something like 4 feet
here.
