Here is another simpler one. A fire hydrant is less than 20 yards away.
Might be those devices are use to inject water in case of fire by the fire brigade to operate the sprinkler system independent from the public water supply. I did see such water entries at a lot of German office and industry buildings. However, they look totally different.
All that devices can be reached from the road. You see here the gap in the wall. Another one is excluded from the fence around the property. There are no signs around.
