Why a Garden Hose in a CMU wall?

I didn’t know the answer to this and that is what I wrote in the report

But why would a garden hose run into (or out of?) a CMU wall 4feet below grade? It went up, somewhere into an interior wall and I could not trace it any further. There were no visible connections to a drain/vent/supplies.

Its wrong , could it have been a dehumidifier drain at one time ???

French drain or the like “any home made drainage field” maybe outside the wall? But what is draining? Is there a second floor or an a/c component above?
